ABSTRACT:
A continuous passive motion device for the hand and its method of use is disclosed. The continuous passive motion hand device includes a base member which is mounted on the hand. The device also includes a rotatable arm mounted on the base member and a rotatable lever mounted on the rotatable arm. A drive bar is fixedly mounted on the rotatable lever and a plurality of linkages connect the drive bar to a respective finger tip. During a cycle of the device, between a full extension and a full flexion of the hand, the drive bar is moved through two hundred and seventy degrees or more by the concerted rotations of the rotatable arm and rotatable lever. Also, during a cycle, each linkage controls and urges the movement of a respective finger tip. Specifically, the end of each linkage that is attached to the drive bar is prevented from rotating about the axis of the guide bar. Additionally, the linkage establishes a second axis for that end of the linkage which is attached to the finger tip. This second axis is maintained substantially parallel to the axis of the guide bar by the linkage, and the linkage also prevents rotation of the finger tip about the second axis to prevent compression and distraction of a finger during a cycle of the device.
