## Abstract

A programmable range of motion system has a frame, a range of motion device, a controller, a computer and sensors. The frame has a seat to support a rehab patient. The range of motion device is attached to the frame. The actuator, servo or alternate mechanism selectively rotates the range of motion device through a range of motion for a rehab patient's limb. The controller controls the actuator, servo or alternate mechanism. The computer is connected electronically to the controller. The computer has a software, program or application including a plurality of programmable range of motion movements for exercising the limb. The sensor detects movements of the actuator, servo or alternate mechanism and records data back to the computer. The term actuator as used hereafter includes servo or alternate articulating mechanism.

## Claims

### Claim 1

A programmable end range of motion system for a leg comprises:
a frame having a seat adjustably mounted on the frame configured to support a rehab patient, a plurality of legs elevating the seat above a floor and one or more frame attachment locations for receiving one or more range of motion improving devices;
a first end range of motion improving device for attachment to a patient's leg, the first end range of motion improving device attached to the frame, a leg linkage connected to said frame, the leg linkage including a support affixed to said frame at one of said attachment locations;
a leg linkage, the leg 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 the 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;
the first link member being independently rotatable about a first link member axis without causing the second link member to rotate about the second link member axis, and the second link member being independently rotatable about the second link member axis without causing the first link member to rotate about the first link member axis;
a leg actuator for rotating the second link member about the second link axis;
a controller controlling the leg actuator for selectively rotating the second link member about the second link axis through the lower leg range of motion or the arm actuator;
a computer connected electronically to the controller, the computer having a software, program or application including a plurality of programmable range of motion movements for exercising the limb; and
a sensor to detect movements of the actuator and record data back to the computer.

### Claim 10 (depends on 1)

The programmable range of motion system of claim 1 wherein the software, program or application provides a neutral or at rest position for the range of motion device.

### Claim 11 (depends on 1)

The programmable range of motion system of claim 1 wherein the software, program or application provides an entry ingress or egress position to facilitate attaching or detaching the range of motion device to the limb.

### Claim 12 (depends on 1)
