Patent ID: 7207960

Claim:
An orthotic device for restoring range of motion to a patient's limb, said orthotic device comprising: a. a first device cuff configured for attaching said device to an upper region of said patient's limb above a limb joint; b. a second device cuff configured for attaching said device to a lower region of said patients limb below said limb joint; c. spring means attached between said first and second cuffs for bending in a manner counteracting muscle contraction of the limb to which the device is attached attempting to bend said limb from an extended position to a more contracted position, said spring means having spring characteristics whereby a counteracting spring force of said spring means increases during an initial flexing of the spring means through a first angle range, then remains peaked during a subsequent flexing of the spring means through a second angle range and finally decreases with a subsequent flexing of the spring means through a third angle range.
