Abstract: Embodiments of the invention are directed to devices and methods for providing shoulder forward flexion, abduction, external rotation, and internal rotation stretch assistance. A device for manipulating an arm of a user, thereby providing abduction or flexion assistance to a shoulder of the user includes an engagement mechanism configured to operatively couple with the user's arm and configured to pivot about an axis defined by the gleno-humeral joint of the shoulder as the shoulder abducts or flexes; a scapular restriction mechanism restricts movement of a scapula of the user's shoulder during a first phase of abduction or flexion and to move in an anatomically correct ratio with gleno-humeral motion during a second phase of abduction or flexion; and a force application system operatively coupled with the engagement mechanism, and configured to apply a force to the engagement mechanism, providing the abduction or flexion assistance to the arm about the shoulder.

Abstract: A device performs a flexion process or an extension process with respect to a knee joint. The device includes a support frame extending in a longitudinal direction. A flexion system includes a foot support assembly configured to translate relative to the support frame in the longitudinal direction thereof and a flexion linear actuator configured to cause the translation of the foot support assembly. The extension system an extension pad assembly including a first expansion pad configured to engage an upper surface of the leg at a position above the knee joint and a second expansion pad configured to engage the upper surface of the leg at a position below the knee joint. An extension linear actuator is configured to translate the extension pad assembly with respect to the transverse direction. A power system is configured to selectively actuate each of the flexion linear actuator and the extension linear actuator.

Abstract: Embodiments of the invention are directed to devices and methods for providing extension and flexion assistance. A device manipulates a foot of a user, thereby providing extension or flexion assistance to an ankle of the user, and includes a footplate positioned at a pre-determined distance from the user and adapted to pivot about an axis defined by the ankle as the foot extends or flexes about the ankle; and a force application system comprising a force applicator connected to the footplate, and a force application mechanism, wherein the force application mechanism is configured to apply a force to the force applicator, thereby providing the extension or flexion assistance to the foot about the ankle.

Abstract: A device is provided for manipulating an arm of a user, thereby providing extension or flexion assistance to the arm about an elbow. The device has an arm engagement system, having an upper arm member with an upper arm frame having a pivot end and a distal end, a posterior elbow pad, a forearm member with a forearm frame having a pivot end and a distal end and a distal wrist pad, and a pivoting connection operatively coupled with the pivot end of the upper arm frame and the pivot end of the forearm frame. A force application system having a force applicator is connected between the distal end and the pivot end of the forearm frame. A force application mechanism is connected at or near the distal end of the upper arm frame.
