ABSTRACT:
A cart for rehabilitation exercise and testing dynamic pushing and pulling forces has a plurality of wheels, a handle, and a braking device attached to one or more pulleys. Said pulleys are affixed to an axle in static positions. Two or more bearingless wheels are affixed to said axle on which the pulleys are positioned in such a manner as to allow said wheels to turn in unison with the axle. A strap, which is suspended on one end from a housing, is held in contact with the perimeter of the pulley and is threaded through a slip buckle. Said slip buckle is connected to one end of a tension spring. The other end of said tension spring is suspended from said housing. Tension on the brake is regulated by adjusting the amount of said strap which is pulled through the slip buckle. The amount of force applied to the cart for rehabilitation exercise, or generated by a subject during a test, can be measured by using a manually-operated, commercially available, force gauge. Using a multiple test protocol, it is possible to analyze consistency of effort during a pushing and pulling assessment.
