A rehabilitative exercise device has two foot supports 8 connected together, which are alternately reciprocatable back and forth in a generally horizontal plane, and pivotable about a horizontal axis perpendicular to the direction of reciprocation. The foot supports 8 may be mounted on a pivotable shaft 7 and be pivotable about a vertical axis relative to the shaft 7. The foot supports may extend from a casing, and be connected to endless belts (figs 7, 8). The device can be clamped 2 to the end of a bed 3. Shaft 7 and foot support 8 rotation may be limited. Variable clamping resistance can prevent shaft 7 pivoting (fig 2). Leg bending exercises can thus be conducted by pushing a foot forward against the resistance of the other foot or of the device, and ankles and calf muscles exercised by swivelling of the foot supports 8 about the horizontal axis. Such swivelling may also reposition the supports 8 on the shaft 7. Supports 8 may be attached by connecting rods and having rollers running along parallel tracks in a body (fig 6). Deep venous thrombosis can be prevented after hip or knee surgery. |
