Abstract: A method and system for treating self-adaptive motion of a jointed body part of a patient, the jointed body part has at least three rotatable body sections interconnected by at least two joints, by collecting data regarding limb movement displaying representations of the data in real time, and modifying current device function based upon such data so as to meet predefined therapeutic treatment parameters with regard to device-actuated movement needs of the limb regarding device-actuated movement, and/or assist limb rotation.

Abstract: The present invention is a portable orthotic system that performs predefined or user-controlled limb movements, collects data regarding limb movement, performs data analysis and displays representations of the data and data analysis results in real time, and modifies current operational parameters based upon such data so as to optimize the rehabilitative process performed by the system.

Abstract: A hydraulically actuated artificial muscle for use with orthetic devices, prosthetic devices or as an actuator for other applications in medical or robotic devices. Working fluid is pumped between two expandable fluid-containing cells, which are complimentary active elements of the artificial muscle. This eliminates the need for a storage reservoir, thereby providing a self-contained, force efficient device. Each of the preferred embodiments described has one or more expandable fluid-containing cell defined by at least one flexible wall. The flexible walls are configured so as to have elastic properties that are limited to predefined directions of expansion and contraction.
