1. A hinge assembly for an orthotic, prosthetic, or rehabilitative device, comprising:

  • a proximal member movably connected to a distal member to allow angular displacement of the proximal member relative to the distal member;

    a spring housing communicating with the proximal and the distal members, wherein movement of the spring housing tracks, and is tracked by, movement of one of the proximal or the distal members; and

    at least one elastomeric spring in bearing engagement with the spring housing, wherein angular displacement of the proximal member relative to the distal member in a first direction compresses the at least one elastomeric spring to dampen the angular displacement in the first direction, wherein decompression of the at least one elastomeric spring urges angular displacement of the proximal member relative to the distal member in a second direction.
