Patient prone with knee flexed 90° Examiner stabilizes patient’s thigh by placing knee over the patient’s distal posterior thigh To perform the moving valgus stress test, the examiner applies and maintains a constant moderate valgus torque to the fully flexed elbow and then quickly extends the elbow. tic sensitivity and specificity values. was assessed by sensitivity, specificity, predictive value, and likelihood ratios. He promptly undergoes operative irrigation and debridement, reduction, vascular bypass of the brachial artery, and hinged elbow fixator placement for 6 weeks. Other limb is off the ground. For the lateral meniscus, apply a varus (adduction) stress during internal rotation of the foot and passive Overall, POCUS demonstrated 100% sensitivity and 50% specificity for medial meniscus tear, yielding a positive predictive value (PPV) of 87. femoral joint during a valgus stress test to optimize isolation of the N To assess a medial tibiofemoral joint sprain, the clinician should test the knee between 06 and . The objective of this study was to evaluate the diagnostic accuracy of a new dynamic clinical examination test for the detection of meniscal tears. Patient supine; Examiner lifts straight leg and bends knee to approximately 20° by placing a hand behind the popliteal fossa (OBQ11. The test is positive if the medial elbow pain is reproduced at the medial collateral ligament and is at maximum between 120 degrees and 70 degrees. 4 Acute elbow injuries are also common, making up approximately the McMurray test and, more globally, to illustrate the impact that indiscriminate test application has on test interpretation. Positive test = Significant gap in medial aspect of knee with valgus stress = MCL injury. 4. 20. the sensitivity and specificity of the stress view were all 100 percent, when we set 4mm as a guideline, the sensitivity was 80 percent and the specificity was 100 percent. 4,10 One study reported lower sensitivity and specificity values for the Thessaly test The Lachman test is the most important physical exam for ACL injuries, as it has 85% sensitivity and 94% specificity in detecting the injury. 9) reported 79% positive results and 21% false negative results for Roos Test is a common test included in the examination of the shoulder, specifically for the presence of Thoracic Outlet Syndrome (TOS). Mark Lasletta, Charles N. Clinical Scenario: At the outpatient orthopedic clinic that I am currently at we tend to see a lot of knee patients, both acute and post-operative. 2004]. Abduction Stress Test. SENSITIVITY SPECIFICITY 29% 96% Fowler and Lubliner, 1989 Examiner applies a constant valgus force to the elbow, while quickly flexing and extending the elbow. Procedure- Apply valgus stress and varus stress. Moving Valgus Stress test has what sensitivity and Specificity for Elbow MCL Pathology . 1, pp. 6% specific for identifying Tenderness above and below the joint line, especially with stress. It may also show signs of meniscal lesions. The Varus Stress Test is commonly reported to evaluate the integrity of the radial collateral ligament, but just like the Valgus Stress Test, has yet to be evaluated for diagnostic utility. In health sciences, validity is commonly assessed by determining the sensitivity and specificity factors. Superior sensitivity and specificity for diagnosing CTS Apley’s Distraction test is an orthopaedic test to assess the ligamentous integrity of the knee joint. According to some sources, the sensitivity of the McMurray test for medial meniscus tears is 53% and the specificity is 59%. 1 Test Position: Standing. Patient position- Standing on the affected limb. , 2003) 25% sensitivity Sensitivity: 26% Specificity: 95% (PCL) Influenced by secondary restraints Varus/Valgus stress for LCL and MCL Injury Valgus Stress: MCL At 30˚ flexion, the cruciates are in their most relaxed state, and pathologic laxity palpated is capsular laxity Medial capsular layers provide stability to valgus What is the sensitivity and specificity of moving valgus stress test at elbow? Sn= 1. Sensitivity. Validity, Reliability. While palpating the medial joint line, the examiner should apply a valgus force to the patient's knee. These injuries often occur in athletes participating in sports that require overhead throwing, such as baseball, javelin, and volleyball. FABER’s (Patrick) Test A test that screens for intra-articular hip pathology, hip, lumbar or sacroiliac dysfunction, or iliopsoas spasm. Geisler, Chris Hummel, and Sarah Piebes (2014) Evaluating Evidence-Informed Clinical Reasoning Proficiency in Oral Practical Examinations. Valgus Elbow Stress test is an elbow examination procedure that determines medial elbow sprain. 75). 3. 31,32 The results of our study challenge the exceptional sensitivity and specificity values of the lever sign test as reported by Lelli and colleagues. Sensitivity of a Clinical Test Foot internally rotated while applying a gentle valgus stress to the knee. 75% Specificity . Outside-in pie crusting with gentle valgus stress may improve visualization and easier . References Summary: The anterior drawer test appears to be a specific test when ruling in a torn ACL when the test is positive and the sensitivity and specificity appear to be better for chronic conditions. The test has therefore often been reported to be of limited value in current clinical practice. The moving valgus stress test has a 100% sensitivity and a 75% specificity for diagnosing UCL injuries (Table 2 3, 7, 8, 11, 13 – 17). 8 Our data suggest that athletic trainers used the val Sensitivity, Specificity. +ve = pain at the elbow (UCL) between 70° and 120° flexion. Procedure. 3 About 20% of the overuse injuries in the young athlete involve the elbow. reference test The instrumented Lachman, valgus, and varus stress tests at the knee and inversion talar tilt test as performed with the LigMaster™ arthrometer on healthy, physically-active adults had moderate reliability. The sensitivity of a test can be explained asthe proportion of people who test positive for a condition among those who actually have the condition. The examiner applies a valgus torque to the elbow during rapid elbow extension. SENSITIVITY SPECIFICITY 29% 96% Fowler and Lubliner, 1989 Pivot Shift Test Indications. 1,2 Response Philip W McClure, PT Assistant Professor, Programs in Physical Therapy, Hahnemann 3. For example, the sensitivityof the Phalen’s test is the proportion of peoplewho have The therapist applies a valgus stress at the knee while the ankle is stabilized in slight lateral rotation either with the hand or with the leg held between the examiner’s arm and trunk. Elbow flexed about 15-20 degrees. When I was reviewing the different orthopedic special tests for the knee with my method, data regarding the sensitivity and specificity value of the test is provided. The literature shows that diagnostic accuracy studies, which evaluate the test described by McMurray, yield remarkably similar estimates of sensitivity (about 26%) and specificity (about 94%). Follow-up   The "moving valgus stress test" for medial collateral ligament tears of the elbow. The key point in performing these tests is taking care not to perform them carelessly. These factors combined could improve patient outcomes. . See reliability; sensitivity; specificity. Examiner does all the motions required to perform test. Same procedure/position as above except that an abduction or valgus force at the distal forearm is applied. 75. 9, No. Detailed description of the examination of the knee is beyond the scope of this article but can be found in the text, Clinical Sports Sensitivity is one measure of how good a test is. MCL most important stabilizer; Common in throwing athletes because throwing causes valgus stress at elbow; Fully ER limb at shoulder; Flex elbow to 15° to relax anterior capsule & unlock olcreanon process from Olecranon fossa; Grab arm above & below the elbow Test Sensitivity 26 to 58 B Test Specificity 59 to 94 C Probability of injury from NURS 612 at Maryville University. If it only causes back pain, then the test is negative.   A + laxity with valgus stress is indicative of MCL tear and + laxity with a varus stress is indicative of a LCL tear. Great test in chronic injuries, but performs worse in acute injuries; Pivot Shift Test (Video Link) Difficult to perform if patient is guarding. In this study, MRI was considered as the reference test. The sensitivity and specificity of the Varus Stress Test is not well studied. The Pivot Shift test is an orthopaedic test of the knee joint to assess stability. 8 and the absence of laxity equals a LR- of 0. 7 percent sensitivity (the percentage of results correctly positive) in diagnosing meniscal tears. Likelihood Ratio +/-. 3). By Chris Faubel, MD — PM&R. It is thought to still be useful when combined with other special tests and subjective finding. 5 Tesla on General Electric Sensitivity: 26% Specificity: 95% (PCL) Influenced by secondary restraints Varus/Valgus stress for LCL and MCL Injury Valgus Stress: MCL At 30˚ flexion, the cruciates are in their most relaxed state, and pathologic laxity palpated is capsular laxity Medial capsular layers provide stability to valgus Diagnosis of Sacroiliac Joint Pain: Validity of individual provocation tests and composites of tests. 100% Sensitivity . 13,16 The sensitivity and specificity of self-assessment of HV using the dichotomous scale were 85 and 88%, respectively. The therapist grasps the distal forearm with one hand and stabilizes the elbow with the other. RESULTS: The moving valgus stress test was highly sensitive (100%, 17 of 17   This test may have decreased sensitivity and specificity in those with The valgus stress test is applied to the knee in both extension and at 30 degrees of  The purpose of the moving valgus stress test is to assess the integrity of the The examiner then maximally flexes the elbow and places a valgus stress to the elbow while externally rotating the shoulder. Elbow flexed 20-30 degrees. Specificity, 0. Orthopedic Exam / Special Tests for Physical Therapy: KNEE Valgus Stress Test Knee: Knock-Kneed Legs: Genu valgum is a condition in which the knees angle in and touch one another when the legs are straightened. Diagnostic accuracy is improved by arthroscopic evaluation or magnetic reso-nance imaging studies. The affected side should always be compared with the contralateral normal side to exclude physiologic laxity, and dorsiflexion of the ankle locks the subtalar joint and increases sensitivity. Gently flex and extend the knee listening for a clicking sound indicative of a trapped meniscus. Athletic Training Education Journal: January-March 2014, Vol. 0 mm compared with the contralateral elbow yielded a sensitivity, specificity, and accuracy of 96%, 81%, and 87%, respectively, for diagnosing UCL tears. Requires full cooperation and relaxation; Start with knee in extension, internally rotate the tibia while placing valgus stress on the knee causing the joint to sublux, then flex the knee, causing a Internal rotation + varus stress = lateral meniscus. The valgus stress (n = 117, 97. 75 The pivot shift test assesses for anterolateral rotatory instability of the knee. A constant moderate valgus torque is applied to the fully flexed elbow, and then, the elbow is extended while maintaining the valgus elbow/external shoulder rotation force. 4 Acute elbow injuries are also common, making up approximately These statistics coincide with the high specificity and low sensitivity of the pivot-shift test that have been reported in the literature. Valgus Stress Test. 1. Young, Department of Health and Society, Linko¨pings Universitet, Linko¨ping, Sweden, Magnolia Diagnostics, New Orleans, LA, USA, Massey University, Institute of Information and Mathematical ANKLE; rupture of Achilles tendon-patient lies prone or has knee bent on chair-examiner squeezes calf and watches for foot to go into plantar flexion To test for a medial meniscus injury externally rotate the foot while applying a valgus force. The patient sits with no back support and with the hand of the test arm resting on the thigh. Test Position: Standing. Determination of meniscal lesions, using McMurray test, had an LR of 1. ) Varus Stress Test; 25% sensitivity (Malanga et al. Valgus stress causes anterior subluxation of the tibia with the knee in  Sensitivity, Specificity. The sensitivity or specificity of a diagnostic test referstohowlikelythetestwill“rulein”or“ruleout”thesuspected diagnosis with a positive or negative test result. Meta-analysis of previous studies showed that these tests have variable sensitivity and specificity especially in acute injuries [3,4]. Grood et al14 examined the ability of a valgus stress test to determine the “grade” of MCL injury and found that knees with complete MCL disruption only registered a motion increase of 5. Patient should be awake and cooperative to perform the Valgus Elbow Stress test. It is the number of "true positives" plus "false negatives," divided by the percent of cases picked up by the test. Physical Exam of the Knee Special tests Valgus stress test MCL Varus stress test LCL Lachmann’s test ACL competency Use a ‘shucking motion between the tibia and femur PCL test ‘thumb sign’ Supine and knee flexed at 90 degrees Normally tibial tubercle is anterior to the femoral condyles Place thumb alongside tibial tubercle In PCL Administration of local anesthesia may be required for proper manipulation. Be sure to not include rotation of the hip in your application of force. 5% specificity as a screening test. 2 Apply abduction (valgus) stress to the knee. (sensitivity 64%, specificity 90%, overall accuracy 84%) [based on one high quality study, Akseki. Furthermore, subsequent research has reported the Thessaly test to have a sensitivity of 89-92% [10], while the McMurray test has been reported to have a sensitivity of only 76% [11]. The moving valgus stress test has 100% sensitivity and 75% specificity for diagnosing UCL injuries. 7, LR Valgus stress test uncovers Ulnar collateral ligament complex instability (1) with a 65% sensitivity, 50% specificity (28). 0% sensitivity and 89. Manual Therapy 10 (2005) 207–218. The therapist applies a valgus stress at the knee while the ankle is stabilized in slight lateral rotation either with the hand or with the leg held between the examiner’s arm and trunk. The forced valgus maneuver, which uses a stress test to cause joint tilt, is crucial in making an accurate diagnosis and deciding on the most appropriate therapeutic approach. Cozen’s test, Mills test and If 100 with no disease are tested and 96 return a negative result, then the test has 96% specificity. Specificity: Are you testing what you think you are testing? Specificity is a statistical measure of how well a test correctly identifies the negative –Varus/valgus stress with pain –McMurray test positive (Bragard’s sign) Medial - sensitivity 35. test is positive if a click is palpable over the medial or lateral tibiofemoral joint line during flexion and extension of the knee during varus (medial tear) or valgus (lateral tear) stress. Which one is the more effective (high sensitivity & specificity) for assessing ligament damage? Moving valgus stress test: 100% sensitivity and 75% specificity The Valgus Stress Test is performed at 0° and 30° of flexion and is the hallmark orthopedic test for evaluating for an MCL injury. These variations constitute different tests with different statistical performance and should not be confused with the original. For both tests, the subjective feeling of apprehension, instability, or localized pain to the MCL indicates MCL injury. Performing the Test: The patient is standing and asked to abduct shoulder to 90 degrees. An audible or palpable snap during extension suggests a tear of the medial meniscus. According to Timmer-man et al. Although not specific for identifying ACL tears, this testing is necessary to evaluate for other or concomitant injuries. Examiner Position Abduction Stress Test (also known as Valgus Stress Testing) This is the most appropriate test for determining the extent of MCL injury. Lucie et al35 Sensitivity: 95% Katz and Fingeroth12 Sensitivity: 98. The test must also be performed in full extension. In acute injuries, the eversion stress test may be of limited clinical value. (from Krishnan, Hawkins & Adams. demographics. Complete ACL rupture is a frequent sports trauma. This is a two-part test Sensitivity= 64 (low) Specificity= 44 (low) Valgus stress? PCL; ACL; MCL which test combines sensitivity and specificity, making it the best examination technique for detecting whether or not an ACL sprain The authors cited the most common, referenced method of interpreting the valgus stress test. Most commonly, varus and valgus stress to the knee is added. The test has a sensitivity of 66% and a specificity of 60% for detecting a UCL strain or tear. Individuals with severe valgus deformities are typically unable to touch their feet together while simultaneously straightening the legs. 5% and pooled specificity 48. The patient tests first the good leg and then the injured leg. Specificity. A modest valgus torque is placed on the forearm until the shoulder reaches its maximum external rotation. Next the therapist maximally flexes the elbow and places a valgus force to the elbow while simultaneously externally rotating the shoulder. There is strong positive correlation between the side to side difference of displacement in stress view and the amount of angle in dial test at 30 degrees of flexion (p= 0. Nursemaid’s Elbow The moving valgus stress test is considered positive if symptoms are provoked within the following range of motion: 70-120 The moving valgus stress test is positive if pain occurs through this range of motion, indicating functional instability of the ulnar collateral ligament Procedure- Apply valgus stress and varus stress. 2010 Mar;2(3):174-81. The patient then flexes the knee to 20 degrees and rotates the femur on the tibia medially and laterally three times while maintaining the 20 degrees flexion. The valgus stress test assesses the effects of valgus stress on the UCL. The valgus stress test is performed with the hip abducted and the knee at 30° of flexion. 0; Sp= . Paul R. The moving valgus stress test, described by O'Driscoll et al. the integrity of the ACL had any effect on the valgus stress test in extension. Gapping >3 mm signifies UCL instability. In case of collateral ligament injury varus or valgus stress test were done to evaluate it. The moving valgus stress test is considered positive if symptoms are provoked within the following range of motion: 70-120 The moving valgus stress test is positive if pain occurs through this range of motion, indicating functional instability of the ulnar collateral ligament To perform the moving valgus stress test, the examiner applies and maintains a constant moderate valgus torque to the fully flexed elbow and then quickly extends the elbow. The specificity values Overall, the McMurray test was shown to have a 78. The test is considered positive for a meniscus tear if the patient experiences medial or lateral joint line discomfort. Patients with an injured MCL often complain of vague medial-sided knee pain, but the combination of a suggestive history, focal tenderness over the ligament, and a positive valgus stress test help to confirm the diagnosis. Maslowski E, Sullivan W, Forster Harwood J, Gonzalez P, Kaufman M, Vidal A, Akuthota V. The patient lies supine on a table/plinth while the therapist passively brings the patients lower extremity that is being tested into flexion, abduction, and external rotation and rests the foot on top of the opposite leg. Requires full cooperation and relaxation; Start with knee in extension, internally rotate the tibia while placing valgus stress on the knee causing the joint to sublux, then flex the knee, causing a Apley’s Distraction test is an orthopaedic test to assess the ligamentous integrity of the knee joint. Pivot Shift Test Indications. The valgus stress test determines the grade of MCL injury It is performed by placing a valgus stress on the knee over the medial joint line at 0° and 30° of knee flexion Grade one sprains show local pain and tenderness but no valgus stress testing laxity Grade two sprains have opening laxity on valgus stress testing, but SENSITIVITY SPECIFICITY 85% 30% Fowler and Lubliner, 1989 MCMURRAY ’’’’S TEST • Knee is flexed and placed in external rotation • Examiner applies a valgus or varus force • Knee is then extended. • Most are highly valgus stress test. The therapist applies a valgus stress at the knee while the ankle is stabilized in slight lateral rotation either with the hand or with the leg held between the examiner’s arm and trunk. Apprehension, pain, or instability, usually from 70 to 120 degrees of flexion, signifies a positive result. Jonathan T Bravman, MD Great test in chronic injuries, but performs worse in acute injuries; Pivot Shift Test (Video Link) Difficult to perform if patient is guarding. 30, while laxity on the Valgus Stress Tests equals a LR+ of 1. 4 Acute elbow injuries are also common, making up approximately Diagnosis of Sacroiliac Joint Pain: Validity of individual provocation tests and composites of tests. Often used along side Apley’s Grind test. A positive test will consist of the lower leg moving greater than 3 mm anteriorly compared to the contralateral knee, and has a ‘soft’ endpoint. Valgus stress tests medial collateral ligament 2. , places the patient's shoulder in 90° of abduction and external rotation. Combined use of stress radiography and arthrometer measurements at the 30° position showed 100% sensitivity and 59. 4% Specificity: 98% Donaldson et al15 Sensitivity: 35% Title: Diagnostic Accuracy of Orthopedic Special Tests for Meniscal Injury . 5 percent specificity (the percentage of results correctly negative) and a 79. Sensitivity and specificity are prevalence-independent test characteristics, as their values are intrinsic to the test and do not depend on the disease prevalence in the population of interest. Interpretation- Pain felt at the medial joint line on varus stress indicate medial meniscus injury and pain felt at the lateral joint line on valgus stress indicate lateral meniscus injury. The knee is first in full extension, and then it is slightly (20-30 degrees) so that it is “unlocked”. Contraindications - Ask candidate to give a list of relative or absolute Define the terms sensitivity and specificity • Valgus/Varus stress test as the McMurray test a meta-analysis performed in 2010 suggested that the Thessaly test has higher test quality than the McMurray test [5]. In this study, 144 baseball players had 191 findings of medial elbow pain, including 53 UCL tears. Start at full extension. 25 26 The passive forearm pronation (PFP) test,26 supination-pronation test 24 and biceps squeeze test 23 inves- and posterior drawer test,26 while the medial knee was assessed with the valgus stress test at 30° and 0° of knee flexion27 28 and the anteromedial drawer test. Figure 5: Moving valgus stress test. Apr 15, 2014 The moving valgus stress test (Figure 4) has a 100% sensitivity and a 75% specificity for diagnosing UCL injuries (Table 23,7,8,11,13–17). McMurray's test is specific (97%) but not very sensitive (52%) (LOE: D). The valgus stress test. The test is performed between 20 to 30 degrees of flexion, so it is less painful than anterior drawer test.   A valgus stress and varus stress is then applied to the medial and lateral compartments of the knee. What it tests. A sensitivity of 52% has been reported in a single study for the inversion talar tilt test. Varus/valgus Drawer Lachman Pivot shift/RPS Meniscal TEST SENSITIVITY Sensitivity is a statistical measure of how well a classification test correctly identifies a condition Sensitivity is one measure of how good a test is. In the valgus stress test the examiner holds the elbow in 70° flexion and applies valgus stress. On the other hand, specificity mainly focuses on measuring the probability of actual negatives. Injury to this structure is commonly reported to follow acute varus stress to the arm and is relatively rare. 1 . Acute: Sensitivity = 49%; Specificity = 58%; Chronic: (i. 29 All clinical tests were recorded prospectively at the initial clinic appointment prior to the avail-ability of imaging findings. ) Interexaminer reliability in 30 degrees flexion - 56% (McClure et al. The diagnostic accuracy of stress radiography including the sensitivity, specificity, and positive and negative predictive values varied considerably depending on the technique and choice of displacement or gapping threshold. Harilainen 11 Sensitivity: 86% Specificity: not reported 72 patients studied with MCL tears confirmed on arthroscopy. Ulnar These tests showed sensitivity ranging from 81% to 100% and specificity ranging from not applicable to 100%. sensitivity, and specificity of injuries to the meniscus and knee the McMurray test was used. When MRI is available, NS is not recommended because of its low specificity, high dosage of ionizing radiation, and other limitations. Sensitivity mainly focuses on measuring the probability of actual positives. Classification of injury Classification Results. (sensitivity and specificity) Caution • Few MSK tests are both highly sensitive and specific. If symptoms provoked within 60 secs then positive • 61% sensitivity, 83% specificity Tinel Test There is a wide variation in the reported sensitivity (16-58%) and specificity (77-98%) of the McMurrays test for detecting meniscal tears. The test is positive if there is reproduction of pain, locking or clicking which may indicate a compromised meniscus. above tend to be static palpation and passive loading/stress tests. For example, the sensitivityof the Phalen’s test is the proportion of peoplewho have Special tests are intended to help guide the physical examination, it is our hope that we can help your understand WHY you perform each test! If you are interested in learning more advanced content, we urge you to look at our insider access pages. The valgus stress test or medial stress test, is a test for damage to the medial collateral ligament of the knee. Anterior Drawer Test - Ankle Special Test: (Supine and Prone) Video Demo, Purpose, Positive Sign, Evidence, Sensitivity, Specificity Bounce Home test is an orthopaedic test of the knee joint that assesses the integrity of the meniscus.

For calculating sensitivity, specificity, positive and negative predictive value, positive and negative likelihood ratio, and accuracy of ultrasonography in detection of traumatic injuries of UCL with 95% confidence interval, Vassarstats medical calculator was used. A strong valgus force is placed on the knee by the upper hand. Ultrasound was also able to show a 67% sensitivity and 83% specificity with a similar PPV of 67% and NPV of 83% for MCL tears. 4,9,10 The results demonstrate greater accuracy with the Thessaly test performed at 20° flexion than at 5° flexion. Modified Milking Maneuver, tests for UCL sprain or tear from overuse. When sensitivity and specificity were available, likelihood ratios (LRs) with 95%  Jun 5, 2018 In some cases the physical examination may be limited by pain or a large effusion, . Requires full cooperation and relaxation; Start with knee in extension, internally rotate the tibia while placing valgus stress on the knee causing the joint to sublux, then flex the knee, causing a Valgus Stress Test (of the knee) Carpal Tunnel Syndrome – Electrodiagnostics. while applying a gentle valgus stress to the knee. The lateral pivot shift test combines a valgus stress (pushing the outside of the . 1 The authors cited the most common, referenced method of interpreting the valgus stress test. Valgus stress test of the knee. 17 For the varus stress test, only one study was identified that reported a sensitivity value of 25% and offered no specificity val- ues. overhead athletes who place significant valgus stress on their elbows (baseball pitchers) method, data regarding the sensitivity and specificity value of the test is provided. This information was . 7%, specificity 85. The talar tilt test 2 (valgus stress test) is positive if there is pain or excessive tilting of the talus on the medial side of the ankle mortise with The standard stress tests include valgus (abduction) and varus (adduction) tests; additionally, Cabot manoeuvre is a commonly used stress test. Conclusion: In case of suspected ACL injury it is recommended to perform the Lachman test. Aprill, Barry McDonald, Sharon B. Medial Collateral Ligament (Ulnar Collateral Ligament) Ulnar Nerve. 13,16 Most commonly, varus and valgus stress to the knee is added. Swap hands and sides. Flex the hip and knee maximally. 19 Future studies must focus on the biomechanical aspects of tests with moderate to high sensitivity and specificity SnNout: A test with a high sensitivity value (Sn) that, when negative (N), helps to rule out a disease (out) SpPin: A test with a high specificity value (Sp) that, when positive (P) helps to rule in a disease (in) Contingency Table True Positive Result A False Positive Result B O’Driscoll et al have described the ‘moving valgus stress test’ and reported a 100% sensitivity and 75% specificity. Technique. McMurray test and Apley grinding test were done to evaluate meniscal tears. 1,2 Response Philip W McClure, PT Assistant Professor, Programs in Physical Therapy, Hahnemann Varus Stress Test, tests for laxity of the Lateral Collateral Ligament (LCL). *click the links below to view a video demonstration of the orthopedic exam in a pop-up […] (sensitivity and specificity) Caution • Few MSK tests are both highly sensitive and specific. 3 (95% . Valgus Stress Test, tests for laxity of the Ulnar Collateral Ligament (UCL). Patient prone with knee flexed 90° Examiner stabilizes patient’s thigh by placing knee over the patient’s distal posterior thigh The anterior drawer test shows good sensitivity and specificity in chronic conditions, respectively 92% (95% CI, 88-95) and 91% (95% CI, 87-94), but not in acute conditions. Sitting on the patient's feet, the clinician takes hold of the tibia and pulls it anteriorly. • Varus Stress Test . ,8) MRI showed 57% sensitivity and 100% specificity for diagnosing medial collateral ligament injury. Also, no valgus stress is applied like pivot shift test which can cause pain when ligamentous injury present. Because this is often misunderstood, it is prudent to add a statement of clarification. Involved Structures. Jonathan T Bravman, MD after taking history. If the tibia moves more than usual, the test is positive. throwing imparts high valgus and extension loads to the athlete’s elbow, causing shear stress posteriorly and tensile stress medially with compression on the lateral side. Patients often report a pop followed by immediate pain and bruising around the medial elbow. Patient must be relaxed. To arrive at the patient's post-test likelihood of disease, interpretation of the stress test result requires integration of the patient's pre-test likelihood with the test's sensitivity and specificity. Lachman test and drawer test were done to evaluate acl injury. From this position a valgus stress is applied and a positive response is signified by pain at the shoulder. 244) A 24-year-old male sustains the right elbow injury shown in Figures A and B. Each MRI was performed using the MR protocol of 1. Pain on the Valgus Stress Test equals a LR+ of 2. 43-48. 149. When stress fracture is suspected, plain radiograph should be the first imaging modality considered because of its availability and low cost. When I was reviewing the different orthopedic special tests for the knee with my The moving valgus stress test (Figure 4) has a 100% sensitivity and a 75% specificity for diagnosing UCL injuries (Table 23,7,8,11,13-17 ). LCL sprain O’Driscoll et al have described the ‘moving valgus stress test’ and reported a 100% sensitivity and 75% specificity. Which one is the more effective (high sensitivity & specificity) for assessing ligament damage? Moving valgus stress test: 100% sensitivity and 75% specificity Valgus Stress Test; 86%-96% sensitivity (Malanga et al. The test is very easy to carry out. 75 What level was the systematic review for MCL repairs by Purcell et al. The varus/valgus stress test is a standard part of the physical examination. Tinel Sign. So, this is the key difference between Valgus stress test uncovers Ulnar collateral ligament complex instability (1) with a 65% sensitivity, 50% specificity (28). LCL sprain Our study showed that Lachman test has the best diagnostic accuracy to detect ACL rupture in acute conditions. SENSITIVITY - 16% SPECIFICITY –80%. A recent meta-analysis of six studies evaluating 4,249 patients showed a pooled sensitivity of 98. Meniscal Tests – Eges Sensitivity – • Probability of a positive test among patients with disease Sensitivity & Specificity of a positive test among patients with • High sensitivity has lower false negatives Specificity – • Probability of a negative test among patients without disease • High specificity has lower false positive These findings may explain the mechanism of stress fractures of the lateral talar body and distal fibula in the present case of late-stage adult-acquired flatfoot with irreducible hindfoot valgus. Thessaly test. Apply a valgus (abduction) force to the knee while externally rotating the foot and passively extending the knee. 5 mm; which by most clinical grading systems is a borderline grade 2 ligament injury (5–10 mm). External rotation + valgus stress = medial meniscus. The therapist abducts the patient's shoulder to 90 degrees. Started in 1995, this collection now contains 6711 interlinked topic pages divided into a tree of 31 specialty books and 731 chapters. 5% sensitive and 48. high sensitivity and specificity rates (overall, 94% and 81%, respectively). Patellar Glide test Knee flexed 20-30o, quadriceps relaxed Patella divided into quadrants and displaced in medial and lateral directions to assess tightness of parapatellar structures Medial glide of 1 quadrant = tight lateral structures ref: Kolowich eta The therapist applies a valgus stress at the knee while the ankle is stabilized in slight lateral rotation either with the hand or with the leg held between the examiner’s arm and trunk Lachman test sensitivity and specificity. is applied to the tibia while the knee is flexed to 40° under a valgus stress ( pushing the outside of the knee medially). In contrast specificity can be defined as the amount to which a diagnostic test is specific for a particular condition. With stress US, joint gapping at the injured elbow greater than 1. The diagnostic validity of hip provocation maneuvers to detect intra-articular hip pathology. 5%), Lachman (n = 96, 80 findings suggested that this new orthopedic test has sensitivity and specificity values of 100% for anterior cruciate ligament Pivot Shift Test Plica Stutter Test Posterior Drawer Test Posterior Sag Sign Q-Angle Test Retreating Meniscus Test Reverse Lachman's Test Rinne ITB Test Single Leg Hop Single Leg Twist Slocum's ALRI Test Slocum's Test Standing Heel-to-Buttock Steinmann's Test Stroke Test Thigh Circumference Test Torsion Test Valgus Stress Test Varus Stress Test Our study showed that Lachman test has the best diagnostic accuracy to detect ACL rupture in acute conditions. It is the number of "true positives" plus "false negatives," divided by the The moving valgus stress test is a modification of the milking maneuver where valgus stress is applied while the elbow is moved through an arc of flexion and extension (Fig. However, the accuracy of the test when done after 5 days of injury increases to 96% sensitivity and 84% specificity. 7 percent and sensitivity of 78. From physical examination, “pain valgus stress 30°” and “laxity valgus stress . It is also knows as the EAST (Elevated Arm Stress Test) Test or the Hands Up Test. Often used when there is a history of ‘gives way’ at the knee, usually due anterior cruciate ligament (ACL) sprain or rupture. reference test The valgus stress test is positive when there is abnormal gapping of the joint on valgus stress and allows assessment of the ulnar collateral ligament complex (38, 43). ? Injury of the MCL can occur along with damage to other structures (eg, meniscus, anterior cruciate ligament) or in isolation. 3 MOIs for LCL . Title: Diagnostic Accuracy of Orthopedic Special Tests for Meniscal Injury . An assessment for one-plane medial instability (gapping of the tibia away  sensitivity and specificity of these tests were extracted. - O'Driscoll's SLAP Test - Shoulder is placed in the extreme abducted and externally rotated position. This test can be performed with the patient sitting or standing. If the ACL is diagnosed as intact via clinical diagnostic tests, the patient could save money by avoiding an MRI. Varus and valgus valgus stress test increased laxity, decreased quality of the endpoint, and/or pain compared with the uninvolved limb; High sensitivity : positiveであればMCL損傷の可能性が一気に高まる。 Low specificity : negativeであったとしてもMCL損傷の可能性は否定できない。他の組織によってfalse negativeが Conclusion: MRI was identified as the most sensitive and specific imaging test for diagnosing stress fractures of the lower extremity. Evidence. To test for a lateral meniscus injury internally rotate the foot while applying a varus force and try to trap the meniscus throughout movement. For collateral ligament testing, it is important to flex the elbow about 15° to relax the anterior capsule and unlock the olecranon from the fossa. While this device has The integrity of the MCL is most commonly tested with the valgus stress test (sensitivity 65%, specificity 50%), milking maneuver, and the moving valgus stress test (sensitivity 100%, specificity valgus instability in overhead athlete (milking maneuver, valgus stress, moving valgus stress test) ulnar neuritis (2-pt discrimination in ulnar distribution, hypothenar bulk, Tinel's along length of nerve) elbow flexion test involves maximal flexion, forearm pronation, wrist hyperextension x 30-60s; ulnar subluxation to test the calcaneofibular ligament the examiner will adduct and invert the calcaneous into a varus position. The Ottawa Knee rule is 98. 7 Provocative tests are typically used to pin point or isolate specific tissues with pathology. This test is performed with the shoulder in 90 degrees of The “moving valgus stress test” reports 100% sensitivity and 75% specificity for UCL laxity. This test may also be done with the patient lying supine. Test accuracy - Sensitivity and specificity Selecting the optimal cardiac stress test" and "Stress testing to for the diagnosis of obstructive coronary heart PDF | The aim of the present study was to analyze the diagnostic accuracy of the commonly used provocative tests in the diagnosis of lateral epicondylitis (LE). Assesses the medial collateral ligament and medial capsule. A total of 16 stress techniques were described for stress radiography of the knee. O’Driscoll et al have described the ‘moving valgus stress test’ and reported a 100% sensitivity and 75% specificity. 5% and a negative predictive value (NPV) of 100%. When combined with imaging, pooled sensitivity for stress testing ranges from 80–90% and specificity ranges from 70–80%; however, several caveats need to be considered. SENSITIVITY SPECIFICITY 85% 30% Fowler and Lubliner, 1989 MCMURRAY ’’’’S TEST • Knee is flexed and placed in external rotation • Examiner applies a valgus or varus force • Knee is then extended. This test is done twice: once in full extension and once in 30 degrees of flexion Valgus Stress Test. The extent to which a measurement correctly measures what it is supposed to measure or to which extent the findings of an investigation reflect the truth. Name of test. 6% 7; Implementation of the OKR in a 1-year controlled trial of 4 Emergency Departments resulted in 26% reduced radiograph use (versus 1% in control group) without adverse consequences from overlooked fractures 6 As shown in the evidence above, the Thessaly test has a higher sensitivity and specificity than the McMurray test and joint line tenderness. The Lachman test is considered the most accurate of the 3 commonly performed clinical tests for an acute ACL tear, showing a pooled sensitivity of 85% (95% confidence interval [CI] 83–87) and a pooled specificity of 94% (95% CI 92–95). e. The Shoulder and the Overhead Athlete) Dan Smith, DO performs the valgus stress test on a patient as part of a full knee examination. However, by using laxity as outcome, the test had a disappointing sensitivity but perfect specificity of 100%. Talar TILT Special Test: POSITIVE TEST 2: A positive test will result in laxity and/or pain ; Sensitivity 67, Specificity 75, LR+ 2. 3 percent. 19 Future studies must focus on the biomechanical throwing imparts high valgus and extension loads to the athlete’s elbow, causing shear stress posteriorly and tensile stress medially with compression on the lateral side. 7% Lateral – sensitivity 22. ) specificity was shown to be 100% and sensitivity 1%. • (+) = Pain and/or a popping/ snapping sensation. Little research has been done on the accuracy of valgus and varus stress tests and the sensativity has varied from 25-86%. For ACL injuries, the Lachman tests were used. With this test, the examiner applies an internal rotation and valgus force to the extended knee and if there is an ACL tear, the tibia will usually sublux anterolaterally SENSITIVITY - 16% SPECIFICITY –80%. , 2003) 86% sensitivity (Harilainen) 96% sensitivity (Garvin et al. Sensitivity and specificity are two statistical measures we frequently use in medicinal tests. At approximately 30° of flexion, the displaced tibia will suddenly reduce, indicating a positive pivot shift test. Sensitivity and specificity values fail to do this 11. 15 To perform this test, the patient is positioned upright with the shoulder abducted to 90°. LCL sprain Moreover, the clinical cutoff value of 3 mm showed 86. Testing for: The integrity of the structures that prevent Valgus deformity of the knee (Joint capsule, medial collateral ligament, cruciate ligaments) Procedure: Patient is supine; Place the affected leg in extension and slight external rotation. They also fail to take into account pre-test probability. Moving Valgus Stress Test, tests for chronic UCL sprain or tear from overuse (sensitivity: 100, specificity: 0. Studies looking at diagnostic accuracy, sensitivity and specificity have demonstrated varied values. This muscle sits laterally on our hips, attaching to the Anterior Superior Iliac Spine (ASIS). The TFL then runs inferiorly and blends into the Iliotibial Tract (ITB). This test is performed with the shoulder in Introduction: Attenuation or rupture of the ulnar collateral ligament of the elbow leads to valgus instability; Epidemiology. For example, "Straight leg test is positive on the left, reproducing the patient's radiating leg symptoms. " [citation needed] A meta-analysis reported the accuracy as: sensitivity 91%; specificity 26% Special Test Physical therapy Valgus Stress Test of the Knee. It involves placing the leg into extension, with one   Mar 1, 2014 The sensitivity and specificity of the clinical tests and magnetic . subclavian artery; brachial plexus; Starting Position Pennsylvania Academy of Family Physicians Foundation Pittsburgh CME Conference November 7 - 9, 2014 Knee and Shoulder Exam Workshop Matthew Silvis, MD Wartenburg's (superficial radial nerve irritation) Tinel's test Phalen's Test for Carpal Tunnel Syndrome • Elbows on the table allowing the wrists to passively flex. Classification of injury Classification The NCCPA™ Musculoskeletal Content Blueprint covers 3 general disorders of the knee Fractures and dislocations of the knee Osgood-Schlatter disease Soft tissue injuries of the knee Below are the most commonly referenced special examinations of the knee that you should know for your examination. A positive test occurs when pain or excessive gapping occurs (some gapping is normal at 30 degrees). Medial Collateral Stress Test (MCL Tear) Internally rotate the foot and apply a valgus (lateral) force on the Apley’s Test Sensitivity 61%, Specificity 70. It is a test that assesses the integrity of the ulnar collateral ligament. 5 Chair test and Coffee cup test (Coonrad,1986) was also suggested to confirm the diagnosis. Sensitivity, 1. 00. Valgus stress testing was performed in 20° of flexion, and testing in extension was not done. These statistics coincide with the high specificity and low sensitivity of the pivot-shift test that have been reported in the literature. Valgus – 20° flexion, wrist pronated to take out PLRI; Valgus Stress Test. However Thompson et al. Conversely, the posterior drawer test and the ankle anterior drawer test had lower levels of intrarater reliability. Patient should be seated during the test. The importance of the valgus stress test in the diagnosis of posterolateral instability of the knee Article in Injury 37(10):1011-4 · November 2006 with 186 Reads How we measure 'reads' These tests showed sensitivity ranging from 81% to 100% and specificity ranging from not applicable to 100%. MCL tear, Direct valgus force on the lateral aspect of the knee, Tenderness  The McMurray test is used to assess the presence of meniscal tears within the knee. - Procedure: Patient seated, shoulder abducted to 90, elbow fully flexed, valgus stress. The test is performed by maximally flexing the elbow. Young, Department of Health and Society, Linko¨pings Universitet, Linko¨ping, Sweden, Magnolia Diagnostics, New Orleans, LA, USA, Massey University, Institute of Information and Mathematical The moving valgus stress test is a modification of the milking maneuver where valgus stress is applied while the elbow is moved through an arc of flexion and extension (Fig. References FPnotebook. Hallux valgus (HV) is a common condition The patient then flexes the knee to 20 degrees and rotates the femur on the tibia medially and laterally three times while maintaining the 20 degrees flexion. tion of the sensitivity and specificity of. 1 The purpose of the moving valgus stress test is to assess the integrity of the medial collateral ligament, or the ulnar collateral ligament of the elbow. An MRI, by contrast, had a reported specificity of 85. ) Interexaminer reliability in 0 degrees extension - 68% (McClure et al. How to do it. 1 To perform the moving valgus stress test, the examiner applies and maintains a constant moderate valgus torque to the fully flexed elbow and then quickly extends the elbow. Orthopedic Exam / Special Tests for Physical Therapy: HIP Tests / PELVIS Tests Modified Ober’s Test/ Ober’s Test: The Tensor Fascia Lata (TFL) is one of our hip flexors. Useful tests should produce large shifts in probability once the result of the test is known. Test Sensitivity 26 to 58 B Test Specificity 59 to 94 C Probability of injury from NURS 612 at Maryville University. Varus Elbow Stres. and posterior drawer test,26 while the medial knee was assessed with the valgus stress test at 30° and 0° of knee flexion27 28 and the anteromedial drawer test. *VALGUS (MCL) stress Proximal hand on lateral aspect of knee holds and stabilizes thigh Distal hand directs ankle laterally Attempt to open knee joint on medial side Estimate the medial joint space and evaluate the stiffness of motion. 3 and the absence of pain equals a LR- of 0. side with a slight valgus strain. 8 Our data suggest that athletic trainers used the val Studies of specificity and sensitivity have demonstrated varied values as a result of poor methodological quality A recent meta-analysis reports sensitivity and specificity to be 70% and 71%. Valgus (Abduction) stress test and Varus (Adduction) stress test are among the most known and used knee tests. the deltoid ligament is examined by abducting and everting the calcaneous into a valgus position. These focus on bridging the gap between the classroom and the clinic. com is a rapid access, point-of-care medical reference for primary care and emergency clinicians. This protocol Valgus Stress Test. It is a very useful test to determine if the patient will have a symptomatic ACL tear or not. This test is performed to measure the amount of joint-line opening of the medial compartment which could indicate an MCL complex injury; also, to look for potential rotation of the tibia on the distal femur. Continue to apply valgus stress and move elbow through ROM to 30 flexion - Positive Test/Grading: Reproduction of medial elbow pain pain from 120-70 flexion - Diagnostic Values: Sensitivity= 100 Specificity= 75 The affected side should always be compared with the contralateral normal side to exclude physiologic laxity, and dorsiflexion of the ankle locks the subtalar joint and increases sensitivity. Ligamentous Instability. 2%, specificity 100% –Thessaly test (full ext & 30) ~ 1/3 with documented tears have NO sig findings on exam Meniscal Injury Studies –XR –MRI Meniscal Injury Treatment –Refer to sensitivity 85% ! specificity 94% acl lesion! sensitivity 24% ! specificity 98% benjaminse 2006 pivot shift anterior drawer test ! sensitivity 92% ! specificity 91% reliable just in chronic conditions benjaminse 2006 combined lesions may affect pivot shift examination warren 2008 miller 2010 pcl evaluation tests posterior drawer posterior sag The sensitivity of a test can be explained asthe proportion of people who test positive for a condition among those who actually have the condition. Three commonly applied physical examinations to diagnose ACL injury are Lachman test, anterior drawer test and pivot shift test [1,2]. The therapist applies a valgus stress at the knee while the ankle is stabilized in slight lateral rotation Sensitivity and specificity values infer the probability of a correct test, given the result of the reference standard 11. 6 The most widely accepted and used tests are Cozens test, Mill’s test and Maudsley test. These results are almost exclusively based on single-center experiences that are typically more accurate than centers in the community. 2% chronic conditions, but its usefulness as a screening test for athletes might be limited due to MRI’s high cost. Summary – Sensitivity vs Specificity. The hook test is performed by hooking a finger under the distal biceps tendon from the lateral side. of meniscal tears provide varying levels of diagnostic parameters including sensitivity and specificity. The sensitivity and specificity of the VST must be evaluated at different. For pain as an outcome, the test showed 65% sensitivity and 50% specificity. Examiner applies a constant valgus force to the elbow, while quickly flexing and extending the elbow. The clinician positions themselves such that one hand is placed on the lateral side of the knee to stabilize femur and the other hand is placed around the medial ankle. Clinical diagnostic tests with a high specificity could allow patients to return to athletics or work sooner, saving time and money by avoiding an MRI test and results. 2% specificity in stress radiography at 30°, which were higher than those in arthrometer measurements. Repetitive valgus stress • Medial Elbow – Tensile force Stress on medial epicondyle physis (growth plate) (aka “Little Leaguer’s elbow”) – Of all elbow growth plates, medial epicondyle is last to fuse – 8‐15 y/o – Treatment • Rest from pitching • Age‐based pitch counts The extent to which a measurement correctly measures what it is supposed to measure or to which extent the findings of an investigation reflect the truth.
