Sep 28, 2001

Appl. No.:

09/967641

Inventors:

David J. Reinkensmeyer - Irvine CA
Christopher C. Painter - Irvine CA
Clifton T. Pang - San Jose CA

Assignee:

The Regents of the University of California - Oakland CA

International Classification:

A61B 5103

US Classification:

600587

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 users movement and provides a means to track sensory motor performance.

Appl. No.:

10/226494

Inventors:

David J. Reinkensmeyer - Irvine CA

Assignee:

The Regents of the University of California - Oakland CA

International Classification:

A63B 2200

US Classification:

482 8, 482 51, 601 33

Abstract:

A backdriveable device for manipulating and measuring limb movement, and a method of use thereof. The device comprises a plurality of forcers, at least one linear guide for constraining the forcers to reciprocate along respective linear trajectories, and a linkage for attachment to a limb of a user, the linkage rotatably connected between the forcers and including two bars rotatably connected together at a vertex. Movement of the forcers along their linear trajectories results in movement of the vertex along a spatial trajectory. In specific embodiments, the forcers are moving coils of a linear motor. The movement and forces applied by the coils can be controlled through a computer interface, providing robotic control of limb movement.

International Classification:

A01K015/02

US Classification:

119700, 119421, 119728

Abstract:

A robotic system and method for locomotion assessment and training of a mammal, exemplified by a rodent. A neurologically impaired animal is suspended over a moving surface in a harness, and the animal's hindlimbs are connected to robotic arms that apply force to the hindlimbs or measure limb movement characteristics. The moving surface can be a physical or virtual surface. A single robotic mechanism comprising two robotic arms can simultaneously apply force, measure limb movement, and provide a virtual surface. Manual or automatic adjustment of load support allows the mammal to step at varying body weight loads.

International Classification:

A61H 3/00

US Classification:

601 5, 601 23, 601 35

Abstract:

A method and a robotic device for locomotion training. The method involves shifting a subject's pelvis without directly contacting the subject's leg, thereby causing the subject's legs to move along a moveable surface. The device comprises two backdriveable robots, each having three pneumatic cylinders that connect to each other at their rod ends for attachment to the subject's torso. Also provided is a method of determining a locomotion training strategy for a pelvic-shifting robot by incorporating dynamic motion optimization.

US Classification:

482001000, 601001000

Abstract:

A method and apparatus for upper limb rehabilitation training of coordinated arm/forearm, forearm/forearm and grasping movements of a motor impaired patient comprises a nonrobotic, passive support, an arm/forearm sensor, a gripping device, a grip sensor capable of measuring an impaired grasping force of a grasping of the patient, a computer to process measurements of coordinated and simultaneous impaired arm/forearm, forearm/forearm and grasping movements to control a graphical representation of the arm/forearm and grasping movements in interaction with a virtual environment, and to provide a visual feedback signal to the patient of simulated normal activities of daily living performed with enhanced motor ability relative to the actual impaired motor ability. A visual feedback signal of the simulated activities of daily living is provided to motivate the patient to perform the upper limb rehabilitation movement training despite limited motor ability.

International Classification:

A61B 500

US Classification:

600595

Abstract:

The present invention provides a guide that can be used to quantify impaired movement performance of a limb, to diagnose whether passive, active, or reflexive impairments limit movement performance, to quantify the resistance to movement provided by the limb at the workspace boundary, and to provide a means for a user to practice improving movement performance of the limb.
