Claims13
An apparatus for controlling movement of a user's leg relative to a stationary surface for enabling muscular stretching of the leg, comprising:
- a boot member configured to receive a single leg of a user and including two opposing sidewalls extending from a back and defining an opening to permit the user to insert the leg between the sidewalls so that the back is adjacent to the Achilles tendon of the user when the user's leg is received in the boot member;
- an inflatable bladder connected along a length of the back of the boot member and positionable adjacent to the surface and configured to expand between the back of the boot member and the stationary surface by a varying amount along the length so that expansion of the bladder causes movement of the entire boot member relative to the other leg of the user and away from the stationary surface.
