Systems and methods are provided for supporting an arm of a user using a harness configured to be worn on a body of a user; and an arm support coupled to the harness configured to support an arm of the user, the arm support configured to accommodate movement of the arm while following the movement without substantially interfering with the movement of the user's arm. One or more compensation elements may be coupled to the arm support to apply an offset force to at least partially offset a gravitational force acting on the arm as the user moves and the arm support follows the movement of the user's arm, the one or more compensation elements providing a force profile that varies the offset force based on an orientation of the arm support.

Systems, devices and methods for providing active and/or passive compression therapy to a body part can include a compression device worn over a compression stocking. The compression device can have a pulley based drive train that is driven by a motor to tighten and loosen compression elements, such as compression straps, in a precise, rapid, and balanced manner. Sensors can be used in the compression device and/or compression stockings to provide feedback to modulate the compression treatment parameters.

The disclosure provides apparatus and methods of use pertaining to a biomechanical finger brace assembly. In one embodiment, the assembly includes a coupling tip, a proximal ring configured to concentrically receive a user's finger, a distal ring configured to concentrically receive the finger, and a rocker formed in an H-shape. The distal ring and the rocker are pivotally suspended between a proximal coordinated pivot point anchored on the proximal ring and a distal coordinated pivot point anchored on the coupling tip, such that movements of the finger within the proximal ring articulate the distal ring together with the rocker to articulate the coupling tip. The coupling tip may include an open end or an enclosed recess to accept a minimally-amputated or non-amputated finger. Other embodiments are also disclosed.

A support for an appendage includes a flexible main body having a generally hollow, tapered, cylindrical shape defining a cavity that is configured to receive an appendage of a wearer. One or more apertures are formed in a wall of the main body to provide bendability to the main body and to allow the appendage to breathe when disposed in the main body. The support further includes a support member disposed adjacent a surface of the main body opposite the one or more apertures to provide rigidity to the main body.

An orthopedic joint hinge assembly includes a first elongated member, a first coupler attached to the first elongated member and including a first interface surface, a second elongated member, and a second coupler attached to the second elongated member and including a second interface surface. Each of the first and second couplers is constrained to rotate about an axis of rotation. The first and second interface surfaces are offset from the axis of rotation and engage each other to block a relative rotation between the first and second members in a first direction and separate from each other to permit a relative rotation in an opposite direction.

An orthotic device includes an upper arm section for receiving an upper portion of an arm of a subject, a forearm section for receiving a forearm section of the arm, and at least one elbow joint rotatably coupling the upper arm section and the forearm section. In the orthotic device, the forearm section includes a release control operatively coupled to the at least one elbow joint, where the release control is configured to transition the at least one elbow joint from a restricted motion state to a free motion state when the release control is activated.

A method for producing an orthosis includes at least the steps of receiving patient data of at least one body part of a patient, wherein the body part is borne substantially without a holding apparatus during the reception, ascertaining and/or receiving reference coordinates of virtual and/or physical target objects on the body part, wherein the body part is borne substantially without a holding apparatus during the ascertainment and/or reception and wherein the target objects represent at least one location on the surface of the body part that is representative for attaching the orthosis on the body part, individually fitting a digital orthosis model on the basis of the patient data and the reference coordinates, and manufacturing the orthosis on the basis of the digital orthosis model that is fitted in this way.

A protective sleeve for treating injury to a wearer's elbow joint comprises a central pad; a protective opening one wearer's medial elbow region, a cap attached on the exterior side of the central pad; a relatively thin sheet; a cylindrical sleeve formed by the relatively thin sheet and the central pad; a first compression strip attached on the interior side within the upper portion of the central pad; a second compression strip attached on the interior side within the lower portion of the central pad; and a fastening means for securing the protective sleeve on the wearer's arm; and a treatment method thereof.

The robotic gripping assist (RGA) provides a user with additional grip strength by supporting and forcefully pushing a user's fingers and hand to a gripping position. Motors are supported on a user's forearm and act as a source for the forced movement. A flexible member is worn on the back of a user's hand. The motors individually draw in or let out wires that cause the flexible member to move from a gripping to non-gripping position, and may pivot the flexible member laterally to provide for ulnar and radial wrist flexion. By bending the flexible member downward, through reeling in wires below the member, the attached fingers of the user are forced into a gripping position. Lateral movement is provided by reeling in the wires on the side of the intended bending direction.

A device for treating a carpal tunnel syndrome comprises: (a) a brace configured for at least partially receiving a patient's hand; (b) displaceable support members mounted on the first member and spaced apart from each other and configured for supporting the patient's palm at areas adjacent to first and fifth metacarpal bones the patient's hand; and (c) a pressing member mounted on the second member and configured for adjustable pressure on dorsum of the patient's hand; The two displaceable support members and pressing member are mountable symmetrically to each other on palm and dorsum of the patient's hand to be received. The device comprises a generator of mechanical vibrations mounted between the displaceable support members. The vibrator is configured to apply the mechanical vibration in an area of carpal tunnel of the patient's hand.
