Abstract
An upper body rotation assembly 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 rotation assembly has a curved chest pad which bears against the chest of the person and a scapula pad which bears against the scapula of the person. The curve of the chest pad is designed to fit the greatest variety of upper body shapes and sizes, providing the greatest comfort and stabilization to the largest portion of the population possible. Two belts, one on each side of the rotation assembly, secure the chest pad to the scapula pad. The rotation assembly is attached to a frame of the machine such that when the person exerts a rotational force against the chest pad and the scapula pad the rotation assembly rotates relative to the frame of the machine. A handle is provided on the chest pad for the person to grab onto with his or her hands while exerting a rotational force against the chest pad and the scapula pad. An operator of the machine can align a natural anatomical axis of the upper body of the person with an axis of rotation of the …
