Systems and methods for improving motor function with assisted exercise

1. A forced exercise system for improving motor function in a patient exhibiting abnormal motor function, said system comprising:

an exercise machine having a movable portion that moves in response to a first contribution to movement of said movable portion by a patient;

a motor coupled to said exercise machine that provides a second contribution to said movement of said movable portion, wherein the second contribution increases a cadence of said movable portion;

at least one mechanical sensor on the exercise machine; and

a control system coupled to said motor and said at least one mechanical sensor, said control system programmed to:

receive data from said at least one mechanical sensor, and

alter the amount of the second contribution based on the data from said at least one mechanical sensor.

2. The system of claim 1 , wherein the at least one mechanical sensor comprises a plurality of sensors that sense speed or cadence, torque generated by the patient, torque generated by the motor, and power generated by the motor.

3. The system of claim 1 , wherein altering the amount of the second contribution alters a speed of the motor.

4. The system of claim 3 , wherein said control system is further programmed to:

compute a patient summary score based on the data from the mechanical sensor, wherein the summary score comprises the following weighted factors:

(a) an intensity of the exercise movement, and

(b) a patient contribution to the exercise movement and a motor contribution to the exercise movement; and

compare the patient summary score to a predetermined desired summary score range.

5. The system of claim 4 , wherein the patient summary score includes the patient contribution to the exercise movement; and

wherein the weighting for the intensity, as expressed in terms of cadence rate in per minute units, is greater than the weighting for the patient contribution to the exercise movement, as expressed in terms of watts of power.

6. The system of claim 4 , wherein the patient summary score includes the patient contribution to the exercise movement; and

wherein the weighting for the intensity is greater than the weighting for the patient contribution to the exercise movement.

7. The system of claim 4 , wherein the patient summary score includes the motor contribution to the exercise movement; and

wherein the weighting for the intensity, as expressed in terms of cadence in per minute units, is greater than the weighting for the motor contribution to the exercise movement, as expressed in tenets of watts of power.

8. The system of claim 4 , wherein the patient summary score includes the motor contribution to the exercise movement; and

wherein the weighting for the intensity is greater than the weighting for the motor contribution to the exercise movement.

9. The system of claim 4 , wherein the patient summary score includes both the patient contribution to the exercise movement and the motor contribution to the exercise movement; and

wherein the weighting for the patient contribution to the exercise movement is greater than the weighting for the motor contribution to the exercise movement, as expressed in the same units of measure.

10. The system of claim 4 , wherein the patient summary score includes both the patient contribution to the exercise movement and the motor contribution to the exercise movement; and

wherein the weighting for the patient contribution to the exercise movement is greater than the weighting for the motor contribution to the exercise movement.

11. The system of claim 3 , wherein said system further comprises a physiological sensor that senses a physiological condition of the patient indicative of aerobic activity.

12. The system of claim 4 , wherein if the patient summary score is less than the predetermined desired summary score range, said control system is further programmed to:

provide instructions to said patient to increase said first contribution.

13. The system of claim 4 , wherein if the patient summary score is more than the predetermined desired summary score range, said control system is further programmed to:

provide instructions to said patient to decrease said first contribution.

14. The system of claim 12 , wherein if the patient does not increase the first contribution after a set time interval, said control system is further programmed to:

increase said second contribution.

15. The system of claim 1 , wherein said exercise machine is one of a stationary exercise bicycle, a treadmill, a stair climber, a treadmill, a rowing machine, or a motorized bicycle.

16. The system of claim 1 , wherein the neurological disorder comprises at least one of Parkinson's Disease, Alzheimer's Disease, dementia, Parkinsonian syndrome, Multiple Sclerosis, amyotrophic lateral sclerosis, dystonia, stroke, and trauma-induced brain damage.

17. A forced exercise system for improving motor function in a patient exhibiting abnormal motor function, said system comprising:

a stationary bicycle having cranks that move in response to a first contribution to movement of said cranks by a patient;

a motor coupled to said exercise machine that provides a second contribution to said movement of said cranks, wherein the second contribution increases a cadence of said cranks;

at least one mechanical sensor on the stationary bicycle; and

a control system coupled to said motor and said at least one mechanical sensor, said control system programmed to:

receive data from said at least one mechanical sensor, and

alter the amount of the second contribution based on the data from said at least one mechanical sensor.
