摘要
Methods and apparatus for exercising or testing the strength of muscles in the lower trunk of the human body. The patient or exerciser is seated with his pelvis and legs fixed against movement and with his head, arms and upper back fixed relative to a movement arm (40) which extends above the seat (22) and is mounted for pivotal movement relative to the seat (22) about a horizontal axis (20). While the movement arm (40) is in a predetermined position, the patient applies a force through the upper back to the movement arm (40) to stress the muscles of the lower trunk, and the strength of these muscles is measured. To exercise these muscles, the movement arm is moved by a force exerted by the upper back against a bias of a resistance weight (W) to lift the weight, and then the force is released to lower the weight and the process is repeated. A compound weight system is employed to allow precise weight adjustment to suit the strength of the exerciser. The movement arm including the weight of the exerciser is balanced about the pivot axis by means of counterweights (110) including an adjustable counterweight (114).
