Disclosed herein are devices, systems, and methods for measuring socket fit in lower limb prostheses and detecting motion of a residual limb relative to a prosthetic socket. Also disclosed herein are methods for developing a socket-fit detection system for sock management that can be applied to adjustable socket systems.

Devices, methods and systems for transmitting signals through a device located in a blood vessel of an animal for stimulating and/or sensing activity of media proximal to the devices. The media can include tissue and/or fluid. A method of controlling an apparatus in communication with a brain machine interface. The method can include measuring a first neural activity in a first neural area and measuring a second neural activity in a second neural area. The first neural activity can be associated with a first intent. The method can include creating and delivering, via the processor, one or more first control signals to the apparatus upon comparing the second neural activity with the first neural activity, and confirming, based on this comparison, that the second neural activity is associated with the first intent.

Prosthetic devices allow for full articulation of the joint, while absorbing impact of the components during normal use that will reduce wear on the device components and prolong life. The device may include a bone implantable component and a bearing component having an articulation surface that is sized and shaped to substantially mate with at least a portion of the bone implantable component and a damping mechanism that includes a contact member disposed at least primarily inside a cavity; a biasing member biasing the contact member toward an upper aperture of the cavity and means for capturing the contact member within the cavity.

A system for control of a device includes at least one sensor module detecting orientation of a user's body part. The at least one sensor module is in communication with a device module configured to command an associated device. The at least one sensor module detects orientation of the body part. The at least one sensor module sends output signals related to orientation of the user's body part to the device module and the device module controls the associated device based on the signals from the at least one sensor module.

A system and method for transmission of a signal for a powered assistive device has a sensor node with a wireless transmitter adapted for digitally transmitting a transmitted signal, the sensor node adapted for receiving and monitoring a sensor signal from a sensor attached to a user, and a master node with a controller and a wireless receiver for receiving the transmitted signal from the wireless transmitter. The master node processes the transmitted signal and communicates a control signal to the powered assistive device. The wireless transmitter transmits the transmitted signal at a first rate when the wireless transmitter adapted to transmit the transmitted signal at a first rate when the sensor signal is indicative of the rest state and to transmit the transmitted signal at a second rate when the sensor signal is indicative of the active state, the second rate being greater than the first rate.

A prosthetic device control apparatus includes at least one sensor worn by a user. The sensor(s) determines a user's movement. A control module is in communication with the sensor(s). The control module communicates movement information to a prosthetic. A method for controlling a prosthetic device includes sensing a user's movement, communicating the movement through a control module to a prosthetic device; and controlling the movement of a prosthetic device.

A method for controlling the standing-phase damping of an artificial knee joint comprising an upper part and a lower part which are secured together in a pivotal manner about a pivot axis, a resistance unit which is arranged between the upper part and the lower part and has an adjustment device via which the damping resistance can be modified, and a control unit which is coupled to the adjustment device and which is connected to at least one sensor. The adjustment is carried out on the basis of sensor data, and the knee angle is detected by the at least one sensor during the standing-phase inflexion up to the terminal standing phase. The flexion damping is increased to a level above an initial flexion damping in order to prevent a further inflexion upon reaching a specified maximum knee angle.

A prosthetic arm apparatus including 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 prosthetic support apparatus that may be adorned by the user. Some segments may provide movement about more than one axis using a single actuator. The prosthetic arm apparatus may include a user interface incorporated therein and may include one or more communication systems for communicating with external devices.
