A cross-crawl chair including a chair frame for supporting a headrest,
chair back, chair seat, right and left arm supports, right and left leg
supports, and four actuators for moving the supports. The chair also
includes a control system which synchronizes the movement of the right
arm actuator with the left leg actuator and the movement of the left arm
actuator with the right leg actuator so as to provide an "arm and
opposing leg" or cross-crawl motion. Further, the electro-mechanical
control system controls a speed, a length of time, and a range of the
cross-crawl motion.
