Carpal tunnel syndrome is a condition in which the median nerve in the wrist is compressed, causing symptoms like numbness and tingling. This study investigated whether the time it takes for provoked symptoms during a controlled-pressure Carpal Compression Test is related to the severity of nerve damage, classified by electrodiagnosis study in 124 hands. The results showed no significant relationship between the time to symptom appearance and the severity of carpal tunnel syndrome. These findings suggest that the duration of the wrist pressure test may not be a reliable indicator of the severity of nerve damage in carpal tunnel syndrome.
