Abstract

A computer-based system provides arm movement therapy for patients with sensory motor impairments. The system is based off a web site that provides access to assessment and therapy exercises designed to test and improve motor coordination in the arm. It operates over the World Wide Web using client-side applets, and can track user movement recovery over time and report it to a remote server computer. The system can also be customized to provide a personalized program of therapeutic exercise to a multiplicity of individuals. A mass manufactured computer input device senses the user'"'"'s movement and provides a means to track sensory motor performance.

means for providing interactive video feedback to said patient in response to a predetermined desired therapeutic exercise.

16. The apparatus of claim 15 where said mass produced computer input device is a force feedback joystick, where said rest is arranged and configure to cancel the effects of gravity on said limb, thus resulting in less torque resistance applied to said force feedback joystick, and where said means for providing interactive video feedback to said patient also provides an assistive force to said limb through said force feedback joystick.

17. The apparatus of claim 16 where said force feedback joystick is a mass produced, unmodified force feedback joystick.

18. The apparatus of claim 15 further comprising means for monitoring rehabilitation status of said patient using client sided computer applets downloaded between said server computer and said client computer.

19. The apparatus of claim 15 further comprising means for providing a library of rehabilitation status tests and therapy activities using JAVA based software communication using client sided computer applets downloaded between said server computer and said client computer.

20. The apparatus of claim 15 further comprising means for displaying changes in sensory, motor, and/or cognitive status of said patient using client sided computer applets downloaded between said server computer and said client computer.

21. The apparatus of claim 15 further comprising means for displaying said patient'"'"'s frequency of use of said status tests and therapy activities using client sided computer applets downloaded between said server computer and said client computer.

22. The apparatus of claim 15 further comprising means for monitoring through said computer network a patient'"'"' performance and frequency of exercise using client sided computer applets downloaded between said server computer and said client computer.
