Abstract
An ankle stretch orthosis includes a foot assembly having a ball support assembly adjustably mounted on a foot plate. The foot assembly includes an adjustment mechanism for selectively adjusting a position of ball support assembly relative to the foot plate to align the ball support assembly with a ball portion of a foot that is one of supinated and pronated.
Claims17
An ankle stretch orthosis comprising a foot assembly having a ball support assembly adjustably mounted on a foot plate, the foot assembly comprising an adjustment mechanism configured for selectively adjusting a position of ball support assembly relative to the foot plate to align the ball support assembly with a ball portion of a foot that is one of supinated and pronated.
An orthosis comprising:
- a frame including a first body portion securement assembly and a second body portion securement assembly movably connected to the first body portion securement assembly for movement relative to the first body portion securement assembly;
- and
- a drive assembly configured to drive movement of the second body portion securement assembly relative to the first body portion securement assembly comprising:
- an actuation mechanism;
- a linkage mechanism comprising at least one driving link and a driven link, the driving link being mounted on the first body portion securement member and operatively connected to the actuation mechanism and driving link to transmit a driving force from the actuation mechanism to the driven link to move the driven link relative to the first body portion securement member;
- and
- a dynamic force mechanism operatively connected to the driven link and the second body portion securement member to transmit a movement force from the driven link to the second body portion securement member, the dynamic force mechanism being configured to move the second body portion securement assembly relative to the first body portion securement assembly using the movement force until a maximum range of motion of the second body portion securement assembly has been reached and being configured to dynamically impart the movement force upon the second body portion securement assembly after the maximum range of motion has been reached.
