The scratch collapse test: a systematic review

The diagnosis of nerve compression relies on collecting diagnostic clues from the history, physical exam, imaging, and diagnostic testing. There are several provocative tests to aide in the diagnosis of nerve compression. The 'Scratch Collapse Test' (SCT) has emerged as a new provocative test to assist in the localization of peripheral nerve compression. This study aims to perform a systematic review of the literature to assess the data on the reliability of the SCT as a diagnostic test for entrapment neuropathy.
