Analysis of pinch and grip strength after carpal tunnel release.

This study evaluates the time required for grip and pinch strength to return to preoperative levels after carpal tunnel release. Grip strength was 28% of preoperative level at 3 weeks; 73% by 6 weeks, and returned to the preoperative level by 3 months. At 6 months grip strength was found to increase to 116%. Pinch strength returned sooner being 74% of preoperative level at 3 weeks and 96% by 6 weeks. By 3 months an increase to 108% was seen and at 6 months an increase to 126% of preoperative levels was found. This data should prove useful in predicting when patients may be able to return to their previous level of occupational-related activity.
