METHODS: The scratch collapse test was studied prospectively in 24 consecutive patients with a diagnosis of common peroneal nerve compression neuropathy. The mechanism behind the scratch collapse test is not understood. Patients who are interned in a hospital for several days and who do not routinely present as a fall risk may present with insidious peroneal nerve … 3 Proponents of the scratch collapse test hypothesize that, if the skin overlying a site of nerve … Nerve compression was evaluated with the Tinel test and the scratch-collapse test. Gillenwater J, Lorant J, Kay S, Au K, Magee W The patient was scheduled for elective surgery release of the nerve. The utility of the scratch collapse test has been demonstrated in examination of patients with carpal and cubital tunnel syndromes and long thoracic and peroneal nerve compressions. The original search terms included “scratch collapse test” and “carpal tunnel syndrome” or “median nerve entrapment”; however, articles were missed with these search terms; therefore, the authors performed a broader search using only “scratch collapse test” to ensure articles were not overlooked. Provocative testing by the scratch collapse test and Tinel's sign was performed. BACKGROUND: The scratch collapse test is a recently described provocative test for diagnosis of peripheral nerve compression. Our purpose was to review the clinical usefulness of the scratch collapse test (SCT) in the diagnosis of proximal entrapment of the median nerve in the forearm. 2 When a painful stimulus is applied to a subject, there is a cutaneous silent period during which voluntary muscle tone is temporarily inhibited.

Evaluation of the scratch collapse test in peroneal nerve compression Gillenwater J, Cheng J, Mackinnon, S. E. Telemedicine: A four-year experience. N2 - BACKGROUND: The scratch collapse test is a recently described provocative test for diagnosis of peripheral nerve compression. It can provide one more clue or confirmation of the level of nerve injury, in addition to providing insight to the hierarchy of nerve injuries within multiple levels. RESULTS: The scratch collapse test showed a sensitivity of 0.77 and a specificity of 0.99, while the Tinel's sign showed 0.65 and 0.99, respectively. The purpose of this study is to introduce the hierarchical SCT as a physical examination tool for identifying multilevel nerve compression in patients with cubital tunnel syndrome. It is difficult for the student of peripheral nerve surgery to select a procedure for a specific patient based on these reports alone. Abstract. Directly over the suspected nerve compression, the examiner gently scratches the skin. Sensation in the deep peroneal nerve distribution on the dorsum of the foot was also tested.
