<P>PROBLEM TO BE SOLVED: To provide a system and a method having a motion-controlled limb and, in particular, an ankle-motion-controlled prosthesis. <P>SOLUTION: The lower end of a lower limb member 102 of a prosthesis 100 is coupled to a foot unit 104 of a pivot assembly 114. As illustrated, the lower limb member 102 is coupled to an ankle plate of the foot unit 104, which extends generally rearward and upward from a toe portion of the foot unit 104. The pivot assembly 114 allows for angular movement of the foot unit 104 with respect to the lower limb member 102. The system includes an actuator 116 that actively controls, or adjusts, the angle between the foot unit and the lower limb member. A processing module controls the movements of the actuator based on data obtained from a sensor module. For instance, sensing module data includes information relating to the gait of a user and is used to adjust the foot unit to substantially mimic the movements of a natural, healthy ankle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
