A hydraulic actuator for orthotics or prosthetics, comprising a control element with a housing, in which a cylinder is arranged, in which a piston is mounted so as to be movable and divides the cylinder into a flexion chamber and an extension chamber, a fluidic connection is arranged between the flexion chamber and the extension chamber, and in each of said chambers there is arranged a control valve for influencing the extension movement or flexion movement, a motorised pump being arranged in the fluidic connection, with the hydraulic fluid being conducted from one chamber to the pump through at least one control valve in an intake-side connection line, and a check valve being arranged in a delivery-side connection line from the pump to the other chamber and blocking a return flow of the pumped medium from this chamber to the pump against the conveying direction of the pump.

The present invention relates to a system for neuromuscular rehabilitation of a patient having an affected limb comprising: a feedback member arranged to give real-time visual feedback; a plurality of electrodes arranged to acquire an electric signal corresponding to an intent to move said affected limb; a control unit configured to: perform pattern recognition of said electric signals, wherein at least one feature in said electric signal is used to predict motion intent of said affected limb adjacent to at least one joint, such aggregated motions of said affected limb are predicted; based on output signals from said performed pattern recognition, control said feedback member to perform actions corresponding to said motions, whereby said actions of said feedback member are individually and simultaneously controlled by said patient via said intended motions.

A prosthetic attachment system and corresponding lock assembly are provided for connecting a distal end of a prosthetic liner to a distal end of a prosthetic socket, by combining vacuum suspension and mechanical suspension. An attachment pin extends from a distal end of the prosthetic liner. A connector assembly secures to a distal end of the prosthetic socket and is adapted for receiving and locking to the attachment pin. A lanyard assembly has a first end secured to the connector assembly and a second end extending outwardly from the distal end of the prosthetic socket and adapted to secure to an exterior surface of the prosthetic socket by an external securing system.

In embodiments, a shock absorber system for a prosthesis includes an outer housing having a bore and attachable to a prosthetic limb; an inner housing, attachable to a prosthetic socket, within the bore for axial and rotational movement relative to the outer housing; a first resilient element within the outer housing that resists axial movement of the inner housing into the bore and urges the inner housing back to an uncompressed configuration; and alternatively or in addition a second resilient element within the outer housing that resists rotational movement of the inner housing relative to the outer housing, wherein a torsional force urging relative rotation between the inner housing and the outer housing causes compression of the second resilient element such that the second resilient element resists the torsional force and urges the inner housing and outer housing back to an aligned configuration.

A system can be used to record real-time pressure and/or shear force data within a socket for a prosthetic device. The system includes a socket for a prosthetic device that can be designed to fit a patient's residual limb. The system also includes a sensor array that can be placed within the socket for the prosthetic device to detect pressure and/or shear force on the patient's residual limb. The sensor array includes a piezo-electric material and a uniform distribution of a plurality of metal pads on either side of the piezo-electric material. Each of the plurality of metal pads on either side of the piezo-electric material comprises at least one wire connected to a common port.

A prosthesis includes first and second prosthetic limb components and a fastening system for fastening the first and second prosthetic limb components. The first prosthetic limb component is provided with a first coupling member and the second prosthetic limb component is provided with a second coupling member. The first coupling member includes a cylindric member having an axis, with a wall generally parallel with said axis. The second coupling member includes a circular skirt element having an axis and having corresponding external dimensions to the cylindric member whereby to permit a sliding fit therewith in an unfastened state. The fastening system includes a resilient member having an axis and is operable to expand laterally, orthogonally with respect to the axis such that, in a coupling mode of operation, the lateral expansion operates to cause the skirt to be in a state of frictional engagement with the other coupling member.
