ABSTRACT:
The exercise apparatus is for supportively aiding a patient's therapeutic upper limb movements and rehabilitation of those corresponding muscles. A skeletal frame has two exercise assemblies mounted on it. Each exercise assembly has a substantially horizontal boom, a first weight resistance assembly in depending relationship to the rearward end of said boom, a flexible connecting line extending from the first weight assembly and then along the boom to a sling for a patient's upper limb, and a depending leg to which the boom is pivotally mounted at its rearward end for pivot swinging adduction and abduction movement of the boom. An adjustable stop system is associated with the boom pivot mounting and permits step-wise setting of stop limits for the adduction and abduction pivot swinging movement of the boom. The flexible connecting line does not extend across the axis for the pivot of the boom. Color coded connecting lines for different slings and weight assemblies are used. Torsion resistance adjustability is provided to vary the resistance to adduction and abduction pivot swinging movement of the boom. A spring-biased locking pin is used to set the stop limits for the movement of the boom.
