A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. The actuator preferably selectively locks during a desired phase in a gait cycle of the limb and minimizes friction against a rotor of the actuator. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up/down stairs, traveling up/down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface. For example, the processing module may receive a heel height input from the user.

Actuator assembly for prosthetic or orthotic joint

Control systems and methods are disclosed for processing a time series of signals associated with the movement of a device associated with a limb. The time series of motion signals is filtered, such as thorough an autoregressive filter, and compared to stored data sets representing a limb-motion event and/or phase. In certain examples, a plurality of accelerometers generate the time series of motion signals based at least on acceleration measurements in three orthogonal directions and/or planes. The acceleration measurements may relate to the movement of an artificial limb, such as a prosthetic or orthotic device. Upon determining an event and/or phase of limb motion, the control system may trigger an actuator to appropriately adjust one or more prosthetic or orthotic joints.

An orthotic frame has proximal and distal frame members joined by a knee joint, and a foot support joined by an ankle joint to a distal end of the distal frame. A knee actuator connected between the proximal and distal frame members has a selective stiffness allowing selection of a relatively rigid stiffness during stance and a relatively flexible stiffness during swing. The stiffness of the knee actuator is selected according to the gait cycle, either mechanically according to dorsal flexion of the ankle joint or electronically according to gait cycle phases recognized based on read sensor data. An ambulatory unit gathers data from sensors located on the orthotic frame. Sensor data may be provided to a base unit for diagnostic and biomechanical evaluation, or evaluated by the ambulatory unit to control active components of the orthotic frame according to the recognized gait cycle phases for functional compensation.
