To the Editor:—  In QUESTIONS AND ANSWERS (203:814, 1968) the problem of stiffness of the wrists after a night's sleep was raised.These symptoms are often due to the carpal tunnel syndrome (compression of the median nerve at the wrist). Paresthesia in the fingers is often reproduced by tapping the median nerve at the wrist (Tinel's sign) or maintaining the wrist in a position of extreme flexion (Phelan sign).1 Measurement of the conductivity of motor and sensory fibers of the median nerve by electrodiagnostic methods is a more precise means for confirmation of the diagnosis.2
