Two hundred and sixty-two patients with carpal tunnel syndrome （CTS） were analyzed retrospectively. Results showed that middle-and older-age women were more apt to have CTS than men

and that the dominant hand was more frequently affected. Hormonal changes

repetitive and forceful movements

awkward positions of hand and wrist

and other factors may be associated with CTS. Typical clinical manifestations include pain and paresthesia in the median nerve territory

worsening at night or in the early morning

and being relieved by shaking the hand. Although the patients may localize the discomfort beyond the territory

sensory changes are variable and not entirely reliable. Conduction abnormalities often appeared selectively in the median nerve distal to the wrist in CTS. If the patient who is clinically suggestive of CTS shows normal conduction with conventional methods

palmar stimulation and inching technique is recommended. The diagnosis of CTS requires confirmation of illness history

symptoms and signs with objective electrodiagnostic tests.
