ABSTRACT:
A lower body stabilization apparatus for a back test, rehabilitation and exercise machine designed for the isolated testing, rehabilitation and exercise of the lower back musculature of a person in rotation about a vertical axis is disclosed. The lower body stabilization apparatus has a seat on which the person sits. The seat may be raised or lowered so that a scapula pad of an upper body rotation assembly of the machine is against the scapula of the person. A seat back which bears against the lower back of the person may be moved forward or backward in order to align the natural anatomical axis below the waist of the person with the axis of rotation of the rotation assembly. A lap belt secured into a lap belt buckle holds the person against the seat back and also down against the seat. Two side cushions bear against the pelvis to prevent lateral movement of the pelvis. Two knee pads of a knee pad assembly bear against the inside of the legs between the knees and thighs. Leg straps of the knee pad assembly looped around the outside of the thighs are secured to leg strap buckels on top of the knee pad assembly above the thighs. The knee pads and the leg straps prevent pelvic rotation and thigh movement. The feet of the person are secured in foot bindings on footplates. The height of the footplates relative to the seat is adjustable.
