Orthoses with microprocessor control placed around the joint of a patient are used to perform and to monitor isometric, range-of-motion, proprioception and isotonic exercises of the joint. A variety of improved hardware elements result in an orthosis that is easier to use and interacts more efficiently with the controller to allow the monitoring of a greater range of motions while holding down cost and provide suitable accurate evaluation of the exercises. Efficient ways of programming the exercises, monitoring the exercises and evaluating the exercise provide a comprehensive program for the rehabilitation of an injured or weakened joint.

1. A method of performing coordination exercises for neuromotor training, the method comprising:flexing a first joint of a patient such that a cursor on a display moves to reach a target position on the display at a selected, predetermined time, the motion of the cursor being correlated with the motion or strain of the joint by way of a sensor in an ambulatory orthosis placed at the joint, the ambulatory orthosis comprising a portable controller and a support portion that fits around the joint such that the ambulatory orthosis is carried by the patient during the flexing step, the controller comprising a digital microprocessor. 2. The method of claim 1 wherein the orthosis comprises:a first support portion that fits around a first body portion on a first side of the joint; a second support portion that fits around a second body portion, the second body portion being on the opposite side of the joint from the first body portion; a flexible connection connecting the first support portion and the second support portion; a position sensor operably connected to the flexible connection such that the position sensor detects the relative orientation of the first support portions with respect to the second support portion. 3. The method of claim 1 wherein the cursor motion is correlated with the strain of a joint by way of a strain sensor.4. The method of claim 1 wherein the cursor moves in two dimensions with the motion in one dimension corresponding to output of a position sensor and motion in the other dimension corresponding to output of a strain sensor.5. The method of claim 1 further comprising flexing a second joint to simultaneously vary the display along with motion of the first joint, wherein variations in the display due to motion of the second joint is determined by the output of a position or strain sensor at the second joint.6. The method of claim 5 wherein the sensors are operably connected to a portable controller comprising a digital microprocessor, the digital microprocessor providing a target for the flexing of the first and second joint on the display.7. The method of claim 1 wherein the sensor is selected from the group consisting of a strain sensor and a position sensor.8. An ambulatory orthosis system comprising:a display, a support portion that fits around a joint and is carried by the patient during activities and a sensor on the support portion, and a portable controller comprising a digital microprocessor, the controller being operably connected to the sensor, wherein the controller controls the display based on signals from the sensor, and wherein the patient, flexing the joint, causes a cursor movement on the display, in which the motion of the cursor is correlated with motion of the joint as detected by the sensor in the support portion when the support portion is associated with the joint of the patient. 9. The ambulatory orthosis system of claim 8 wherein the display is integral with the portable controller.10. The ambulatory orthosis system of claim 8 wherein the display is part of a television.11. The ambulatory orthosis of claim 8 wherein the support portion has an appropriate structure to fit around a patient's knee.12. The ambulatory orthosis of claim 8 wherein the support portion has an appropriate structure to fit around a patient's elbow.13. The ambulatory orthosis of claim 8 wherein the display provides a target to be reached by the patient through their movement of the joint.14. The ambulatory orthosis of claim 8 wherein the sensor comprises a strain sensor.15. The ambulatory orthosis of claim 8 wherein the sensor comprises a position sensor connected to a hinge.16. The ambulatory orthosis of claim 8 wherein the orthosis comprises a binge.17. An ambulatory orthosis system comprising:a display, a support portion that fits around a joint and is carried by the patient during activities and a sensor on the support portion, wherein the support portion comprises a hinge, and a portable controller comprising a digital microprocessor, the controller being operably connected to the sensor, wherein the controller controls the display based on signals from the sensor, and wherein the patient, flexing the joint, causes a cursor movement on the display, in which the motion of the cursor is correlated with motion or strain of the joint as detected by the sensor in the support portion is associated with the joint of the patient.
