A prosthetic arm apparatus comprising a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a harness mount that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user.

A prosthetic arm apparatus comprising a plurality of interconnected segments that provide the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connected to one another and connectable to a harness mount that may be adorned by the user. Each segment of the plurality of segments includes an actuator providing a portion of the movement capability, and each segment may operate independently of each of the other segments of the plurality of segments. One segment of the plurality of segments includes a non-backdriving clutch that transfers power from the actuator to an output interface of the segment when the actuator is actuated to generate movement of the output interface in either of two opposing directions and prevents backward transfer of power from the output interface to the actuator of the segment in both of the two opposing directions.

Proprioceptive feedback is provided in a residual limb of a person that includes forming a linkage between a pair of agonist and antagonist muscles, forming a sliding surface over which the agonist and antagonist muscles slide. The sliding surface can include a synovial sleeve, a bridge formed between the distal ends of bones, or a fixture that is osseointegrated into the bone. The invention also includes a system for transdermal electrical communication in a person that includes a percutaneous access device, a sensory device that communicates signals between a muscle and the percutaneous device, and a stimulation device in communication with the percutaneous access device. In another embodiment, a closed-loop functional stimulation system restores lost functionality to a person that suffers from impairment of a neurological control system or at least partial loss of a limb.

The present invention relates to a system (100, 200) for neuromuscular rehabilitation of a patient (102, 202) having an affected limb (104, 204) comprising: a feedback member arranged to give real-time visual feedback; a plurality of electrodes (110, 210) arranged to acquire an electric signal corresponding to an intent to move said affected limb (104, 204); a control unit (108, 208) 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 (104, 204) adjacent to at least one joint, such aggregated motions of said affected limb (104, 204) 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 (102, 202) via said intended motions.

Methods and systems to interface between physiological devices and a prosthetic device, including to receive a plurality of types of physiological activity signals from a user, decode a user movement intent from each of the plurality of signals types, and fuse the movement intents into a joint decision to control moveable elements of the prosthetic device.

Disclosed is a virtual tactile implementation device, which includes one or more micro-displacement stimulation elements in close contact with a skin, a signal processor that applies a displacement signal to the micro-displacement stimulation element, and a power supply device that supplies electrical energy to the micro-displacement stimulation element and the signal processor, and the signal processor controls a waveform and an amplitude of the displacement signal to allow the micro-displacement stimulation element to selectively fire action potentials of a plurality of tactile receptors within the skin, and controls a time interval at which each of the action potentials is fired to allow the micro-displacement stimulation element to provide a sense of pressure or a sense of texture.

Various aspects of this disclosure relate to a layered polymer substrate with electrodes and conductive ink embedded in the substrate. In some embodiments, a prosthetic liner may be bonded onto the polymer substrate. The substrate may include an interconnect coupled to the electrodes via the conductive ink. The system may include a controller (e.g., an electrode controller) in communication with the electrodes via the conductive ink. The electrodes may be activated such that they may stimulate nerve fibers in a user's residual limb.
