This exercise mobilizes the primary muscle tendons that are within the carpal tunnel. This can reduce pressure on the median nerve as any adhesions that may have developed through the inflammatory healing process can be released, allowing the tendons and more importantly the nerve to move within the tunnel.
To perform the exercise, move your fingers from position 1 to 2 to 3 and reverse. See the table below for details
