How do we initiate exercises wrt flexor tendon and extensor tendon repair? Which joints in the wrist should be given active and passive exercises?

The joints to be mobilized depend on which tendons were surgically repaired. The choice to employ either passive or active exercises depends on the stage of injury. The early post-op stage is the stage of protection of the surgery site and isometric exercises are recommended. In the later stages, passive movements may be commenced which may then be progressed to active exercises.
