Clinical and experimental studies have shown that postoperative rehabilitation is an important factor that improves digital function after flexor tendon repair. In the current study, the effect of synergistic wrist and finger motion therapy and fixed flexed wrist motion therapy on the in vivo gliding excursion was evaluated after repair of partial laceration of the canine flexor digitorum profundus tendon. The gliding excursion of the repaired tendons treated with synergistic wrist and finger motion therapy was significantly greater than that of tendons rehabilitated with the wrist fixation therapy, suggesting that wrist extension generates force that can pull the repair site through the pulley, thereby increasing passive excursion of the tendon. As a result of increased tendon excursion, synergistic therapy may improve the clinical outcome after repair of partial tendon lacerations.
