ABSTRACT:
A machine for exercising or testing the lumbar muscles of the human body. The machine has a movement arm pivotable about a horizontal axis through forces exerted by said muscles while the subject is seated with his pelvis restrained against movement and with his back engaging a resistance pad. The rear of the pelvis engages a pelvic pad which is movable to detect any unwanted movement of the pelvis during the exercise. The resistance pad is movable relative to the movement arm to enable measurement of the effective lever arm of the moment applied to the movement arm by the subject. On one side of the movement arm is a mechanism for connecting the movement arm to a weight stack to impose a predetermined yieldable resistance to the movement arm. On the other side of the movement arm is an adjustable counterweight mechanism which may be releasably connected to the movement arm to counterbalance the subject's torso mass.
