Dynamic splinting following flexor tendon repair

Electromyographic investigation of subjects wearing dynamic flexor tendon repair (Kleinert) splints shows a wide variability in the amount of contraction in the flexor digitorum profundus muscle during extension of the finger. We suggest there is no advantage in giving extra resistance to the extensor muscles, and that the strength of the rubber bands needs to be only just sufficient to flex the finger passively back to its resting position.
