Range of motion improvement device
First Claim
Patent Images
1. An end range of motion improving device comprising:
- a linkage, the linkage including;
a first link member;
a second link member supported on the first link member, the second link member configured for being secured to a lower leg of a patient and being rotatable about a second link member axis for rotating the lower leg of the patient about a knee axis of the patient through a lower leg range of motion, the second link member axis being displaceable into a selectable fixed position aligned with the knee axis and maintaining the fixed position during rotation of the second link member;
an actuator for rotating the second link member about the second link member axis; and
a controller controlling the actuator for selectively rotating the second member link member about the second link axis through the lower leg range of motion.

7. An end range of motion improving device comprising:
-
a linkage, the linkage including; a first link member; a second link member mounted on the first link member, the second link member configured for being secured to a lower leg of a patient and being rotatable about a second link member axis for rotating the lower leg of the patient about a knee axis of the patient through a preset lower leg range of motion, the second link member axis being displaceable into a selectable fixed position aligned with the knee axis by an adjustment of the first link member, the fixed position being maintained during rotation of the second link member; an actuator for rotating the second link member about the second link member axis; and a controller controlling the actuator for selectively rotating the second link member about the second link member axis through the preset lower leg range of motion.
