1. A prosthetic foot comprising:
a first plate extending between a proximal end and a distal end; a second plate disposed below the first plate and extending between a proximal end and a distal end; an adapter pivotally coupled to the proximal end of the first plate at a first joint; and a mechanical actuator assembly coupled to the proximal end of the second plate and pivotally coupled to the adapter at a second joint disposed rearward of the first joint, the actuator adjustable to adjust a heel height of the prosthetic foot, the actuator comprising:
a first component having one or more magnets;a second component having one or more magnets, the second component sized to extend into an opening in the first component;wherein when at least one magnet or at least a portion of at least one magnet in the first component having a first polarity is aligned with at least one magnet or at least a portion of at least one magnet in the second component having a second polarity opposite to the first polarity, a position of the second component is substantially fixed relative to the first component, substantially locking the actuator, andwherein when the at least one magnet or at least a portion of at least one magnet in the first component is not aligned with the at least one magnet or at least a portion of at least one magnet in the second component, the position of the second component is adjustable relative to the first component to adjust a heel height of the prosthetic foot. |
