After a hand that has sustained a tendon injury,passive versus active limitations of joint motion must be evaluated. Limitations in active motion may indi-cate joint stiffness, muscle weakness,or scar adhe-sions. If passive motion is greater than active motion, the therapist should consider that tendons may be caught in the scar tissue. The therapist should be able to determine if a tendon is adhering and causing a flexion contracture or if the tendon is free but the joint itself is stiff. Treatment should be based on this type of evaluation.
