Despite the fact that carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, the diagnostic accuracy of clinical screening examinations for CTS is controversial. This nerve characteristically arises from the anterior rami of three spinal nerve roots: the fifth, sixth, and seventh cervical nerves (C5-C7), although the root from C7 may be absent. Apely's Scratch Test Gerber Lift-Off Test Feagin Test Neer's Test. This study aims to perform a systematic review of literature to assess the data on the reliability of the SCT as a diagnostic test for entrapment neuropathy. This article offers a clear outline of all stages of the test to improve interrater reliability. a fairly common diagnosis and should be treated as a significant functional problem The purpose of our study was to determine the diagnostic accuracy of the SCT for CTS. The preoperative EMG did not correlate with intraoperative nerve stimulation in 13 patients (72%) and did correlate in 5 patients (28%); 3 patients had a nerve transfer (3 thoracodorsal to long thoracic at lateral chest, 1 pec to long thoracic at supraclavicular incision). Cause of long thoracic nerve palsy: a possible dynamic fascial sling cause.
