The prosthesis or orthosis comprising a moveable component, a motor operable to move the component, wherein the motor has at least one operating parameter, the application of which to the motor results in the component having at least one operating condition; and an electronic device operable to: determine at least one operating parameter of the motor and determine at least one instantaneous operating condition of the component from a predetermined operating profile of the motor and component and the determined at least one operating parameter of the motor, the predetermined operating profile of the motor and component being based on one or more operating parameter inputs to the motor and one or more resulting operating condition outputs of the component.
An adjustable prosthetic socket includes proximal and distal ends and an axis extending between the proximal and distal ends. A distal base is adapted to support a distal portion of a residual limb and is located at the distal end of the socket. First and second spines extend upward from the distal base that define at least part of a circumference of the socket about the axis. A proximal support is connected to the second spine and arranged to distribute pressure from the second spine over a portion of the residual limb. A tensioning system is operatively connected to the first and second spines and arranged to selectively adjust the circumference of the socket. The tensioning system includes a dial tensioner connected to the first spine.
