Abstract
In one aspect, an orthosis for increasing range of motion of a body joint generally includes first and second dynamic force mechanisms for simultaneously applying a dynamic force to body portions on opposite sides of a body joint.
Claims18
An orthosis for increasing range of motion of a body joint, the orthosis comprising:
- first and second dynamic force mechanisms for simultaneously applying a dynamic force to body portions on opposite sides of a body joint;
- and
- first and second linkage mechanisms operably connected to the corresponding one of the first and second dynamic force mechanisms,
- wherein the first and second dynamic force mechanisms each comprise a lever arm and a force element, the lever arms being pivotably connected to corresponding bell cranks by lever pivot pins, the force elements being configured to apply torques to respective lever arms to pivot the lever arms about the lever pivot pins and relative to the respective bell crank links in a biased direction.

An orthosis for increasing range of motion of a body joint, the orthosis comprising:
- an actuator mechanism;
- first and second linkage mechanisms operatively connected to the actuator mechanism, the first and second linkage mechanisms being crank mechanisms comprising first and second bell crank links;
- first and second cuffs operatively connected to the first and second linkage mechanisms, wherein the first and second linkage mechanisms are configured to transmit force from the actuator mechanism to the respective first and second cuffs to impart movement of the first and second cuffs relative to one another;
- first and second dynamic force mechanisms operably connected to the first and second bell crank links and comprising levers corresponding to the first and second cuffs,
- wherein the first and second dynamic force mechanisms comprise a lever arm and a force element, the lever arms being pivotably connected to corresponding bell crank links by lever pivot pins, the force elements being configured to apply torques to respective lever arms to pivot the lever arms about the lever pivot pins and relative to the respective bell crank links in a biased direction.

- first and second dynamic force mechanisms for simultaneously applying a dynamic force to body portions on opposite sides of a body joint;
- and
- first and second linkage mechanisms operably connected to the corresponding one of the first and second dynamic force mechanisms;
- a transmission assembly, wherein the first and second linkage mechanisms are operatively connected to an output gear of a transmission assembly;
- a drive assembly, the drive assembly comprises an input shaft, a knob, and a clutch mechanism,
- wherein the transmission assembly comprises an input gear connected to the input shaft, a reduction gear, an output shaft, and the output gear,
- wherein the input gear is rotatable about an input axis, while each of the reduction gear, output shaft, and output gear are rotatable about an output axis, the input gear is operatively connected to the reduction gear for driving rotation of the reduction gear about the output axis,
- wherein the output axis is generally parallel to the input axis.
