At the elbow, the radial nerve enters a narrow tunnel formed by muscles, tendon, and bone. Eur Radiol. Scratch collapse test for evaluation of carpal and cubital tunnel syndrome. The scratch collapse test had significantly higher sensitivity than Tinel’s test and the flexion/nerve compression test for carpal tunnel and cubital tunnel syndromes. The scratch collapse test (SCT) is a relatively new clinical test in which a positive result implies entrapment neuropathy of the nerve tested. Eighty-eight adult patients that were prescribed electrophysiological testing t …. 6 The SCT is based on the theory that stimulation of the skin around the area of nerve injury (‘Scratch’) results in a brief period of inhibition of voluntary … National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Surgical and Clinical Decision Making in Isolated Long Thoracic Nerve Palsy. Kuschner SH, Ebramzadeh E, Johnson D, Brien WW, Sherman R. Neurotherapeutics. The scratch collapse test (SCT) is a relatively new clinical test in which a positive result implies entrapment neuropathy of the nerve tested. J Clin Neurosci. The sensitivity of the scratch collapse test was not superior to other clinical signs and physical examination manoeuvers for CTS, and the specificity of the scratch collapse test was superior to that of Durkan's test and CTS-6 lax. The scratch collapse test (sensitivity 64%, specificity 99%) is a supplemental exam that uses a different outcome measure to diagnose CTS. This is also termed ulnar nerve entrapment and is the second most common compression neuropathy in the upper extremity after carpal tunnel syndrome. Szabo RM, Slater RR Jr, Farver TB, Stanton DB, Sharman WK. Epub 2013 Sep 22. Tinel's sign and Phalen's test in carpal tunnel syndrome. Scratch Collapse Test. 2012 Sep;12(50):307-18. doi: 10.15557/JoU.2012.0016. Provocative testing can be done with Tinel testing over the course of the nerve, having patients hold their elbow in maximal flexion while the examiner holds pressure on the ulnar nerve at the cubital tunnel and a test called the scratch-collapse test. 2009 Jul;16(7):929-33. doi: 10.1016/j.jocn.2008.09.004. ... Mackinnon-Patterson B, Beck JL, Mackinnon SE. Accuracy for this test was 82% for carpal tunnel syndrome and 89% for cubital tunnel syndrome. This prospective study measured and compared the diagnostic performance characteristics of various clinical signs and physical examination manoeuvres for carpal tunnel syndrome (CTS), including the scratch collapse test.  |  This prospective study measured and compared the diagnostic performance characteristics of various clinical signs and physical examination manoeuvres for carpal tunnel syndrome (CTS), including the scratch collapse test. Epub 2009 Mar 27.  |  Basic Test: • Patient seated/standing, arms at sides with elbows flexed to 90°, wrists at neutral and fingers extended. doi: 10.1097/GOX.0000000000001933. The scratch collapse test (SCT) is a novel test that may be of diagnostic advantage. Eighty-eight adult patients that were prescribed electrophysiological testing to diagnose CTS were enrolled in the study. NIH doi: 10.1097/GOX.0000000000001933.  |  Results showed the scratch collapse test had a sensitivity of 7% and a specificity of 78% for carpal tunnel syndrome when using electrodiagnostic criteria as a reference standard. HHS Scratch Collapse Test for Carpal Tunnel Syndrome: A Systematic Review and Meta-analysis. Evaluation of the scratch collapse test for the diagnosis of carpal tunnel syndrome. Tinel's test had the highest negative predictive value (98%) for cubital tunnel syndrome. Tinel test, however, had the highest negative predictive value (98%) of all tests for cubital tunnel.14 A thorough elbow exam is needed to look for other sources of pain and to rule out other etiologies for the See this image and copyright information in PMC. Epub 2017 May 25. Introduced in the year 2008, this test helps to diagnose CTS and differentiate … Hand (N Y). All the potential sites of entrapment should be released, including a complete rele… The test offers an advantage over these other tests in that … Conclusions: The scratch collapse test had significantly higher sensitivity than Tinel's test and the flexion/nerve compression test for carpal tunnel and cubital tunnel syndromes. Evaluation of the Scratch Collapse Test for Carpal and Cubital Tunnel Syndrome-A Prospective, Blinded Study. J Hand Surg Am. NLM Susan Mackinnon, the pioneer of SCT, ‘was first introduced to the SCT in the early 1990 s by Bronson and Beck’,5 and the first study describing SCT was published in 2008 ‘Scratch collapse test for evaluation of carpal and cubital tunnel syndrome’. The scratch collapse test had significantly higher sensitivity than Tinel's test and the flexion/nerve compression test for carpal tunnel and cubital tunnel syndromes. Scratch Collapse Test Is a Useful Clinical Sign in Assessing Long Thoracic Nerve Entrapment. CONCLUSIONS: The scratch collapse test had significantly higher sensitivity than Tinel's test and the flexion/nerve compression test for carpal tunnel and cubital tunnel syndromes. NIH The value of diagnostic testing in carpal tunnel syndrome. Initially described for carpal and cubital tunnel syndromes, subsequent authors have found it useful for the assessment of median, ulna, radial… The purpose of our study was to determine the diagnostic accuracy of the SCT for CTS. Attending surgeons documented symptoms and results of standard clinical manoeuvres. A clinical test for the cubital tunnel syndrome. RESULTS • 170 wrists and 139 elbows studied • Sn and Sp for the two primary observers summarized in Table 1 • κwas -0.025 (worse than chance alone) for the resident/tech 1 and 0.211 (fair) for the resident/tech 2 CONCLUSIONS • Sn and Sp for the SCT were lower than those found in non-blinded studies. Radial Tunnel Syndrome is a syndrome resulting from the compression of the posterior interosseous nerve at the level of the proximal forearm.  |   |  2008 Nov;33(9):1518-24. doi: 10.1016/j.jhsa.2008.05.022. 24 A positive test is noted if there is transient loss of muscle resistance resulting in the arm collapsing, thus, coining the term of this provocative test “the scratch collapse test.” This concept can also be applied to other nerve … Of clinical tests for identifying multilevel ulnar nerve entrapment ; scapula winging scratch...
