Abstract: A device for rehabilitating or strengthening the ankle includes a plank that is connected by a transversely oriented hinge and a longitudinally oriented pivot, as well as a pair of compression springs at its forward end. The connections of the plank to the underlying base limit the plank to motion in two directions about two axes, thereby providing four types of therapeutic ranges of motion, including dorsiflexion and plantar flexion, eversion and inversion. A transversely slidable foot rest enables the user to hold device 21 in position with one foot while using the plank of the device to rehabilitate the other foot.

Abstract: For lifting, aligning and holding a side-hinged door during its installation into a door frame, an improved hand tool, of the type having an elongated base with proximal and distal ends, a fulcrum attached to the base near its distal end, and a pivoting lever, has the improvements of: (a) a vertical guide extending from the base proximate its proximal end, and (b) a movable lifting member having side portions that have a configuration which is adapted to align and cooperate with the vertical guides so as to limit the movement of the lifting member to only vertical motions, and with this lifting member having a front surface that that is configured to allow it to be easily placed beneath the bottom surface of a door and to support the door over a sufficient part of its width so as to minimize the chance of the lateral tilting of the door when it is being installed.
