Abstract
A self-operable knee therapy device includes a first elongate platform on which the lower leg of a person may be secured so that the back of the leg is in contact with the platform, a second elongate platform pivotally joined at one end to an end of the first platform and on which the upper leg of the person may be secured with the back of the upper leg being in contact with the second platform, and an elongate central support member pivotally joined at its upper end to the joined ends of the first and second platforms for supporting the joined ends in an elevated position. A handle is coupled to the first platform to enable grasping by a user so that when the handle is moved away from the person, the free end of the first platform is caused to pivot downwardly, and when the handle is moved toward the person, the free end is caused to pivot upwardly. By manual movement of the handle, the lower leg can be pivoted relative to the upper leg of a person in a selective manner to exercise and rehabilitate the knee and/or leg muscles.
