Comparing the rate of carpal tunnel syndrome between 100 female students and 100women with other occupation

Carpal tunnel syndrome (CTS) is a clinical entity characterized with pain, paresthesias, and numbness in the distribution of the median nerve with weakness and atrophy of the thenar muscle in advanced cases. It is universally accepted that CTS is the clinical concordate of compression of the median nerve as it pass through the carpal channel. It is reported to be the most common of the entrapment neuropathies. Increasing evidence suggests that occupational factors, including forceful use of the hands repetitive use of wrist hands, and hand-arm vibration, are etiologic for CTS. When occurring as result of occupational exposure, the term "worked related carpal tunnel syndrome" is applied. In this study, we have randomly chosen and examined 100 university female students without any hard work and 100 women with various occupations (dentist, carpet- weaver, tailor, surgeon, housewife, etc) for having CTS with neurography. The neurography test showed that 3 female students and 29 working and housewife women were suffering from this syndrome (the ratio were about 1110). Nerve conduction velocity have been decreased significantly and distal nerve latency have been increased significantly (p<0.001) in subjects with CTS. There was a direct relationship between having CTS and wrist activity (x^2= 25.1, p<0.001). The results showed that the rate of CTS increases in women with higher wrist activity.
