Abstract

A system for use in rehabilitation of a target patient is provided. The system includes at least two bicycle devices for use by the target patient and a second operator other than the target patient. The at least two bicycle devices each include pedals. At least one of the pedals may have at least one sensor mounted thereon for monitoring operation of the first bicycle device and the target's condition. A servomotor is coupled to the pedals for providing gear-like resistance or pedal assistance for the at least two bicycle devices. A controller is programmed to electrically couple the at least two bicycle devices to each other.

First claim

What is claimed is:

1. A system for use in rehabilitation of a target patient, the system comprising:
at least two bicycle devices for use by the target patient and a second operator other than the target patient, the at least two bicycle devices each including:
pedals, indicating operation of the first bicycle device and the target patient's condition; and
a servomotor coupled to the pedals for alternatively providing resistance and assistance for the at least one bicycle device;
a controller programmed to couple the at least two bicycle devices to each other; and
wherein the controller includes a human in the loop control system programmed to:
react and adapt to changes initiated by at least one of the target patient and the second operator;
detect and accommodate inappropriate interaction by at least one of the target patient and the second operator;
accommodate different skill level and competency levels between the target patient and the second operator;
detect and respond to wear and fault conditions of the system; and/or
protect the at least one of the target patient and the second operator and the system.

2. The system of claim 1 , wherein the controller is further programmed to acquire performance data taken from the group of torque, speed and user ability related to each of the at least two bicycle devices.

3. The system of claim 1 , wherein the controller is further programmed to:
collect performance data from each of the target patient and the second operator; and
generate a mathematical model of an interaction between the target patient and the second operator from the performance data.

4. The system of claim 3 , wherein the mathematical model provides the controlled coupling between the at least two bicycle devices to effect dynamic changes in the control of each of the bikes.

5. The system of claim 3 , wherein the controller is further programmed to:
generate a statistical model developed from patient data; and
adjust operation of the system to be responsive to the mathematical model and the statistical model.

6. The system of claim 5 , wherein the controller adjusts operation of the system by being further programmed to:
dynamically alter a cadence and a torque experienced by each of the target patient and the second operator through a real-time power management control algorithm.

7. The system of claim 3 , wherein the controller is further programmed to dynamically alter a cadence and a torque experienced by each of the target patient and the second operator through a machine-learning algorithm.

8. The system of claim 1 , wherein the system operates with the target patient operating one of the at least two bicycle devices and a second user different from the target patient operating another of the at least two bicycle devices.

9. The system of claim 1 , wherein the system operates with the target patient operating one of the at least two bicycle devices and the controller operating another of the at least two bicycle devices.

10. The system of claim 1 , wherein the human in the loop control system includes:
a plant component that includes actual output data of the target patient, the second operator and the system; and
a plant model component that includes an expected output data of the target patient, the second operator, and the system.

11. A system for use in rehabilitation of a target patient, the system comprising:
at least one bicycle device for the target patient, the at least one bicycle device including: pedals, at least one of the pedals having at least one sensor associated therewith for monitoring operation of the at least one bicycle device and a condition of the target patient;
a servomotor coupled to the pedals for providing resistance for the at least one bicycle device;
a controller programmed to:
acquire data related to target patient performance obtained from the at least one sensor; and
adjust operation of the system in real time responsive to the target patient performance; and
wherein the target patient operates the first bicycle device and the controller operates the second bicycle device.

12. The system of claim 11 , wherein the controller is further programmed to acquire performance data related to each of the at least one bicycle device.

13. The system of claim 11 , wherein the controller is further programmed to: collect performance data from the target patient; and
generate in real time a mathematical model of an interaction between the target patient and the at least one bicycle device from the performance data.

14. The system of claim 13 , wherein the mathematical model provides a coupling between a first bicycle device and a second bicycle device.

15. The system of claim 11 , wherein the controller includes:
a control model for providing the user with an experience similar to riding a tandem bicycle; and
a captain model for sensing capabilities of the rider and adjust the process control for the system accordingly.

16. A system for use in rehabilitation of a target patient, the system comprising:
at least one bicycle device for the target patient, the at least one bicycle device including:
pedals, at least one of the pedals having at least one sensor associated therewith for monitoring operation of the at least one bicycle device and a condition of the target patient;
a servomotor coupled to the pedals for providing resistance for the at least one bicycle device;
a controller programmed to:
acquire data related to target patient performance obtained from the at last one sensor; and
adjust operation of the system in real time responsive to the target patient performance; and
wherein the controller includes a human in the loop control system, the human in the loop control system including:
a plant component that includes actual output data of the target patient and the at least one bicycle device; and
a plant model component that includes expected output data of the target patient and the at least one bicycle device.

17. A system for use in rehabilitation of a target patient, the system comprising:
at least one bicycle device for the target patient, the at least one bicycle device including:
pedals, at least one of the pedals having at least one sensor associated therewith for monitoring operation of the at least one bicycle device and a condition of the target patient;
a servomotor coupled to the pedals for providing resistance for the at least one bicycle device;
a controller programmed to:
acquire data related to target patient performance obtained from the at least one sensor; and
adjust operation of the system in real time responsive to the target patient performance; and
wherein the controller includes at least one of:
