Carpal Tunnel Syndrome | Special Tests | Rationale & Interpretation

The video tutorial covers various diagnostic tests for carpal tunnel syndrome, including nerve conduction studies and several special tests like Phalen's, Reverse Phalen's, Tinel's, Hand Elevation, Flick Sign, and Square Wrist Sign. Each test is explained with its procedure, sensitivity, and specificity, helping in diagnosing carpal tunnel syndrome effectively.
