Method and apparatus for restraining the legs and pelvis for exercising and/or testing the lower trunk of the human body

摘要

Method and apparatus of the present invention fix the legs of a seated human body with the knees bent and the thighs including the femurs extending downwardly and rearwardly with the rear of the pelvis engaged against a pelvic pad located above the rear of the seat on which the body is seated. Forward movement of the legs is restrained by footrests receiving the feet of the body while upward movement of the legs and thighs is prevented by a pad extending across the top of the thighs. Because of the orientation and fixation of the femurs which are connected to the pelvis, the pelvis cannot rotate or pivot and nor can the legs due to their restraint by the thigh pads and footrests. In the apparatus disclosed, the thigh pad is fixed to a pivot arm pivotable in a plane between the legs, and the pad and its pivot arm are held in operative position due to the inclination of the thighs and the restraint of the legs.
