Carpal tunnel syndrome (CTS), compression of the median nerve as it passes through the wrist, is the most common entrapment syndrome of upper extremity. The purpose of this study was to evaluate the relationships between clinical findings (symptoms and physical findings) and the electrophysiologic severity of CTS by Bland classification. We evaluated the clinical findings for 382 hands and electrophysiologic examination for 3 years. The results were as follows: 1) The most common symptom was tingling sensation and sensory loss (94%). 2) The most common physical finding was muscle weakness or atrophy of the abductor pollicis brevis (APB) (71%). 3) The frequency of symptoms and physical findings obtained were significantly correlated with electrophysiologic severity of CTS groups (p<0.05). In conclusion, these results indicated that a positive correlation existed between the frequency of clinical findings and electrophysiologic severity of CTS.
