A brace configured for attachment to a joint of a subject is provided. The brace includes a first arm having a first end and a second end. The brace includes a second arm having a first end and a second end. The brace includes a hinge assembly coupling the first end of the first arm with the first end of the second arm such that the first arm and the second arm are movable to different relative angular orientations. The brace includes a potentiometer coupled to the hinge assembly. A method of monitoring a relative angular orientation of a first arm of a brace relative to a second arm of the brace is also provided. The method includes monitoring an output of a potentiometer coupled to one of the first arm and the second arm.

A walking training system includes a leg orthosis fitted to a leg of a user, a pulling member coupled to the leg orthosis, a first drive mechanism configured to apply pull force to the pulling member, according to walking motion of the user, a holding device that holds the pulling member at a holding level, at a point between a coupling point of the leg orthosis and the first drive mechanism, and a second drive mechanism configured to change the holding level of the pulling member held by the holding device, according to the walking motion of the user.

A system for supporting a liner on a frame element includes a liner and a frame element. A fastener connects the liner to the frame element, such that the fastener corresponds to an aperture defined by the frame element. The fastener is configured and dimensioned to removably secure to the frame element at the at least one aperture. The frame element comprises a semi-rigid or rigid base frame element, and an interface layer secured about the base frame element. The interface layer is formed from a resilient material more compressible than the base frame element, and the liner is more flexible than the interface layer.

The present disclosure is relates to an orthosis device. The orthosis device, in one embodiment, includes an actuator housing, and an electric motor coupled to the actuator housing, the electric motor including a motor stator and a motor rotor, and the electric motor further having high output torque. The orthosis device, in this embodiment, further includes a low-ratio transmission coupled to the actuator housing, the transmission including a gear system coupled to the actuator housing, and a drive system coupling the electric motor and the gear system, wherein a combination of the electric motor and transmission provide a user backdrivable orthosis device.

Artificial limbs and joints that behave like biological limbs and joints employ a synthetic actuator which consumes negligible power when exerting zero force, consumes negligible power when outputting force at constant length (isometric) and while performing dissipative, nonconservative work, is capable of independently engaging flexion and extension tendon-like, series springs, is capable of independently varying joint position and stiffness, and exploits series elasticity for mechanical power amplification.

A hinge has a hinge body forming an articulating section extending between a first end and a second end of the hinge. The articulating section is adapted to bend from a neutral axis when the first and second ends are parallel to an angular range in which the first end is arranged among a plurality of angles within the angular range relative to the second end. The hinge body may define a receptacle along the articulating section, and an insert may be provided for insertion into the receptacle. The insert can modify the stiffness of the hinge in the angular range and is arranged parallel to the neutral axis.

Apparatus and methods relate to a multi-modal rehabilitation device having a reconfigurably lockable, adjustable knee stabilizer and a removable foot plate provided with removable resistance elements. In an illustrative example, the resistance elements may be repositionable. The foot plate may be provided with rollers. The rollers may be configured for use in gliding exercises. The rollers may be configured for self-massage therapy. The rollers may be removable. The rollers may be disposed in a removable leg band which may be disposed around a leg of a user. In an illustrative example, the device further includes a graduated self-deflating thermal-compression device. Various embodiments may provide multiple therapy modalities in an efficient, economical, and user-friendly device.

An adjustable knee ankle foot orthosis for unloading weight from a knee joint afflicted with osteoarthritis, thus reducing pain and improving mobility, comprising: an upper and lower frame connected by an unloading hinge assembly, optionally comprising a sensor and processor allowing for remote or automatic control of brace tension. In embodiments, the brace includes a user mechanism that is capable of adjusting a tensioning element while the brace is being worn. In other embodiments, electronic motors, sensors, and indicators may be included in the brace to improve brace performance and user interaction.

A brace incorporates an elongated strut having rigid hinge bars interconnected by an adjustable dual-axis ROM hinge. An exchangeable hinge stop is removably positioned within the ROM hinge, and designed to engage the hinge bars at a predetermined flexion/extension limit, thereby restricting pivoting movement of the strut and custom limiting a range of extension or flexion of the body part. A stop retention post cooperates with a flex member to hold the hinge stop in position relative to the first and second hinge bars. Lifting the flex member outwardly away from the hinge plate allows the hinge stop to be removed from the ROM hinge and exchanged.
