Features for a prosthetic wrist and associated methods are described. The wrist couples with a prosthetic socket and a prosthetic hand. The wrist may rotate the hand. The wrist includes features to prevent or mitigate undesirable separation of the wrist from the socket. The wrist may have an expanding coupling, such as an expanding ring, to better secure the wrist with the socket. An actuator may cause the coupling to expand outward to prevent or mitigate undesirable separation of the wrist from the socket. Alternatively or in addition, the wrist may include torque control features to prevent undesirable or premature separation of the hand from the wrist, for example when using a “quick wrist disconnect” (QWD) apparatus. A torque control method may tailor or limit multiple torques to be applied by the wrist to the hand based on operational requirements and phases, such as anticipated torque loads and operational timing.

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.

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.

Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD. A processor analyzes the data collected to determine a locomotion activity of the user and selects one or more control parameters based on the locomotion activity. The inference layer may be situated between a reactive layer control module and a learning layer control module of the control system architecture.

The invention relates to a method for transmitting data between a prosthesis system and an input device, wherein the prosthesis system has a plurality of prosthesis components which have at least one electronic and/or mechatronic component, wherein the prosthesis system is connected to the input device via at least one interface, wherein at least two electronic and/or mechatronic components, in a state when connected to the prosthesis components, are together connected to the input device, and data are transmitted or exchanged via the one input device.

A method for configuring a prosthesis and/or orthosis or for determining malpositions in the set-up of a prosthesis or orthosis of the lower limb. The method includes recording a first set of measurement data of at least one sensor that is fixed to a body part of a person, wherein the first set of measurement data is allocated to a first state of movement of the person, recording a second set of measurement data of at least one sensor that is fixed to a body part of a person, wherein the second set of measurement data is allocated to a second state of movement of the person, and evaluating the first and second set of measurement data.

Technology is described to provide a powered prosthetic wrist flexion device or elbow device. This device helps individuals with upper-limb loss to orient and position grasped objects.

A system for powering a prosthetic arm is disclosed. The system includes at least one internal battery located in the prosthetic arm, at least one external battery connected to the prosthetic arm, and a master controller configured to connect either the at least one internal battery or the at least one external battery to a power bus to power the prosthetic arm.

An active suspension system with body wearable device integration is disclosed. The system includes a prosthetic having a shock assembly with at least one active valve and a controller communicatively coupled with the at least one active valve of the shock assembly, the controller configured to communicate damping adjustment information to the at least one active valve of the shock assembly, the damping adjustment information used by said at least one active valve to modify a damping characteristic of the shock assembly.

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.
