Abstract : Rehabilitation following flexor tendon repair has been the focus of a number of prior studies, with inconsistent results. To compare the effects of active and passive mobilization exercises on function and range of motion, records of 72 patients undergoing post-operative rehabilitation were examined. There was no significant difference between the two processes in the outcomes. However, over time, it seems that both strategies work. Rehabilitation helps patients' range of motion and joint function whether it is based on passive or active mobilization. To determine which form of exercise should be favored, more studies are required.
