The Washington Regimen: rehabilitation of the hand following flexor tendon injuries.

This article describes the use of the "Washington Regimen" of early controlled motion in the rehabilitation of flexor tendon injuries of the hand. This regimen is derived from a combination of Kleinert's controlled active extension with rubber-hand passive flexion, Duran's controlled passive techniques, and the modification of the Kleinert orthosis that uses a palmar pulley system. Based on results of clinical investigations, this regimen of early controlled motion appears effective in inhibiting peritendinous scarring, joint contractures, and other complications that commonly occur secondary to flexor tendon repairs. A six-week staged regimen of postoperative rehabilitation is presented. Splint design, exercise regimen, and rationale for treatment are reviewed.
