Study Details:

Brief Summary
This study will look at gender differences in high resolution ultrasonographic measurements of the median nerve as it relates to carpal tunnel syndrome, and predictors of good outcome with conservative management.

Intervention(s)
This is a natural history study of carpal tunnel syndrome and consists of nerve conduction studies, ultrasound and questionnaires at two study visits separated by 6 weeks of wrist splinting, along with a 3 month follow-up questionnaire via mail. Compensation will be provided for all visits.
