A prosthetic or orthotic device includes a body configured to support at least a portion of a human limb of a user wearing the prosthetic or orthotic device. The device can also include a shock absorption member coupled to the body. The shock absorption member includes one or more magnetorheological elastomer (MRE) springs disposed between a first portion of the body and a second portion of the body. The one or more MRE springs are selectively actuatable to vary a stiffness of the shock absorption member via the application of a magnetic flux, thereby adjusting a stiffness of the body of the prosthetic or orthotic device to a level corresponding to an activity level of the user.

Prosthetic and orthotic devices having magnetorheological elastomer spring with controllable stiffness

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.

Intelligent orthosis

Disclosed is a device and method to aid in the monitoring of the health of an amputee's limb. The device employs a socket preferably including a liner. The liner may be constructed of an inner layer and an outer layer. The inner layer is configured to hold a plurality of sensors able to monitor the physiological health of the enclosed limb. The inner layer further employs a transmission device able to receive data from the sensors and send such data to an end user; the end user being a computer, the amputee, or a doctor. Through receipt of such data, the end user is aided in monitoring the health of the limb.
