Abstract

Passive knee extension systems and related methods of promoting knee extension. The system comprises a shell comprising a pliable base portion and a rigid top portion. The base portion comprises first and second ends, first and second lateral sides, a top side and an interior cavity. The system further comprises a first and second mounting straps extending between the first and second lateral sides proximate to the first and second ends, respectively. The system also comprises a rigid container with an open top positioned within the interior cavity, and a plurality of base weights positionable within exterior weight pockets of the first and second lateral sides. The system further comprises a compressible support cushion positionable on the top portion. The top portion is movable between a closed position extending over the top of the container, and an open position with the top of the container being exposed.

Dependent claims

A knee extension system, comprising:

a shell comprising a pliable base portion and a rigid top portion, wherein the pliable base portion comprises a first end, a second end, a first lateral side extending between the first and second ends comprising a first plurality of exterior weight pockets, a second lateral side extending between the first and second ends comprising a second plurality of exterior weight pockets, a bottom side, a top side and an interior cavity;
a first mounting strap extending between the first and second lateral sides proximate to the first end;
a second mounting strap extending between the first and second lateral sides proximate to the second end;
a rigid, hollow container with an open top positioned within the interior cavity;
a compressible support cushion positionable on a top surface of the top portion of the shell;
and
a plurality of base weights individually positionable within the first and second plurality of exterior weight pockets,
wherein the top portion of the shell is movable with respect to the base portion of the shell between a closed position wherein the top portion extends over the top side of the base portion and the top of the container, and an open position wherein at least a portion of the top portion is spaced from the top side of the base portion and the top of the container is exposed.

A method, comprising:

promoting extension of a knee of an extended supported leg of a user, comprising:
positioning a first mounting strap of a knee extension system over the user's leg at a first side of the knee, the first mounting strap extending between first and second lateral sides of a pliable base portion of a shell of the knee extension system;
positioning a second mounting strap of the knee extension system over the user's leg at a second side of the knee, the second mounting strap extending between the first and second lateral sides of the pliable base portion, wherein the first mounting strap is positioned proximate to a first end of the base portion of the knee extension system, and the second mounting strap is positioned proximate to a second end of the base portion of the knee extension system;
placing a first base weight of the knee extension system within a first exterior weight pocket of a first plurality of exterior weight pockets positioned on the first lateral side of the base portion;
and
placing a second base weight of the knee extension system within a first exterior weight pocket of a second plurality of exterior weight pockets position on the second lateral side of the base portion,
wherein positioning the first mounting strap and positioning the second mounting strap over the user's leg suspends the shell of the knee extension system from the user's leg beneath a posterior side of the user's knee.
