Performing Tinel's test and Phalen's test
CARPAL TUNNEL SYNDROME (CTS) is caused by compression of the median nerve as it travels with the flexor tendons through a canal at the base of the hand, called the carpal tunnel. Tinel's test and Phalen's test are physical assessment maneuvers that may produce the symptoms of CTS and help in diagnosis.
To perform Tinel's test:
Gently tap (percuss) over the median nerve on the ventral aspect of the patient's wrist.
