An accurate diagnosis of carpal tunnel syndrome can be made if the wrist-flexion test is positive, Tinel’s sign is present over the median nerve at the wrist, and all objective sensory findings are strictly limited to the distribution of the median nerve distal to the wrist. These are the three most reliable clinical findings, and in almost every patient found to have the syndrome at least two of the three findings are present.1
