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.

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.

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.

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.

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.
