B
Feedback:
Phalen's sign involves having the client flex the wrist for 30 seconds to determine if pain or numbness occurs (a positive sign for carpal tunnel syndrome). The examiner percusses the median nerve, located on the inner aspect of the wrist, to elicit this response. Tinel's sign is also a test that elicits pain and numbness in clients with carpal tunnel syndrome and occurs by lightly tapping the median nerve. Crepitus is a grating sound that is elicited when two bones rub together. Spasm is not indicative of carpal tunnel syndrome.
