Orthotic/electrotherapy for treating contractures due to immobility
First Claim
1. An orthotic device useful for extending the range of angular movement between adjacent first and second skeletal body parts which have been drawn to and involuntarily held in a limited angular range of motion (LROM) position relative to one another by contraction of muscle fibers and connective tissue due to immobility of one or both of said skeletal body parts, said orthotic device comprising:
- a. a first orthotic device portion;
b. a second orthotic device portion;
c. means interconnecting said first and second orthotic device portions for permitting angular movement and for enabling the setting of a selected angle therebetween;
d. means for applying or attaching said first orthotic device portion to the first body part and said second orthotic device portion to the second body part after the second body part has been moved against contracture forces away from said LROM position to an extended range of motion (EROM) position relative to the first body part, said first and second orthotic device portions being then set at said EROM position relative to one another;
e. spring means associated with the first and second orthotic device portions for urging the second orthotic device portion to return to said EROM position in response to the second orthotic device portion being pulled by the applied or attached first body part through at least one of muscular contraction and the elastic properties of the muscles and connective tissue away from said EROM position and toward said LROM position, thereby causing a cycling movement of said second body part between said EROM and LROM angular positions and a gradual loosening of said second body part relative to said first body part and an ultimate extending of the range of angular motion of said second body part relative to said first body part at said EROM position without additional external intervention;
f. an electrode component positioned to be effective to conduct an electrical current to at least one of said body parts; and
g. an electrotherapy unit in electrical communication with said electrode component, said electrotherapy unit adapted to provide electrical energy to at least one of the first and second skeletal body parts to reduce the contraction of the contracted muscle fibers.

Abstract
A therapeutic system comprising an orthotic device adapted to extend the range of angular movement between adjacent first and second skeletal body parts which have been drawn to and involuntarily held in a limited angular range of motion position relative to one another by contraction of muscle fibers and connective tissue due to immobility of one or both of said skeletal body parts and an electrode component positioned to be effective to conduct an electrical current to at least one of said body parts.

22. A therapeutic system comprising:
-
a. an orthotic device adapted to extend the range of angular movement between adjacent first and second skeletal body parts which have been drawn to and involuntarily held in a limited angular range of motion position relative to one another by a contraction of agonist muscle fibers and connective tissue due to immobility and neurological disfunction of one or both of said skeletal body parts, trauma, injury or surgical intervention affecting a joint connected to the first skeletal body part and the second skeletal body part;
b. an electrode component positioned to be effective to conduct an electrical current to at least one of said first and second skeletal body parts; and
c. an electrotherapy unit in electrical communication with said electrode component, said electrotherapy unit adapted to provide electrical energy to at least one of said first and second skeletal body parts to inhibit the contraction of the agonist muscle fibers, wherein the electrotherapy unit is adapted to deliver electrical current to at least one of said first and second skeletal body parts according to a regimen selected from the group consisting of administering a biphasic electrical pulse, using low voltage to stimulate a motor nerve, applying two electrical currents of different frequencies that summate to stimulate large muscle fibers, and applying high voltage galvanically.
