Abstract
A muscle exercise and diagnostic system which includes a lever arm, a mounting arrangement for mounting the lever arm for rotation about a fixed axis, and a connecting arrangement for connecting a selected portion of the human body to the lever arm for rotation about a selected anatomical axis of rotation. The connecting arrangement provides a fixed tangential and sliding mounting to permit free radial movement of the point of attachment of the patient relative to the axis of rotation of the lever arm. A velocity control arrangement coupled to the lever arm limits the velocity in accordance with a preselected velocity control function. The radial distance from the point of attachment to the axis of rotation is measured and used in the velocity control function. Range of motion limits are set in one embodiment by way of a potentiometer for each limit position and by a pushbutton and limit storing arrangement in another embodiment.
