Abstract: An orthotic device including a plurality of posterior dynamic struts and an adjustable posterior multiple strut engager, wherein the plurality of posterior dynamic struts has a first posterior dynamic strut and one or more additional posterior dynamic struts, and wherein the adjustable posterior multiple strut engager is affixed to the first posterior dynamic strut and is adapted to restrain the movement of said one or more additional posterior dynamic struts, and wherein the adjustable posterior multiple strut engager may be adjusted to engage said one or more additional posterior dynamic struts in combination with the first posterior dynamic strut, thereby forming a single posterior dynamic strut assembly of greater rigidity than the first posterior dynamic strut alone.

Abstract: Disclosed herein are devices and methods for therapeutic exercise. In one embodiment a device is disclosed for facilitating a therapeutic exercise of a user. The device includes an upper rigid member configured for contacting a right knee of the user, a lower rigid member configured for contacting a right instep of the user, a vertical brace, a first mechanical coupling configured for attaching the upper rigid member to the vertical brace, and a second mechanical coupling configured for attaching the lower rigid member to the vertical brace. In another embodiment, a method of performing a therapeutic exercise using a device is disclosed. The method includes positioning a right knee of a user against an upper rigid member of the device and positioning a right instep of the user against a lower rigid member of the device.

Abstract: A knee brace includes: an elastic sleeve; first and second stiffening members coupled together to crisscross to form an X-shape, and secured to a medial side of the sleeve; third and fourth stiffening members similarly coupled together and secured to a lateral side of the sleeve; and a plurality of slits in the sleeve into a corresponding pockets that receive a thermal pack. The thermal packs and pockets are triangular shaped, with two triangular-shaped pockets on the medial side of the sleeve, and two on the lateral side, each disposed in a respective triangular shape positioned between the x-shape of the stiffening members. The pairs of stiffening members are either: fixedly coupled together to store energy when the user bends at the knee, and to expend the stored energy to assist in lifting the user upward; or pivotally coupled together to pivot according to movements of the wearer's knee joint.
