ABSTRACT:
A cart for measuring dynamic physiological forces has a plurality of wheels, a handle, and a brake attached to at least one of the wheels for controlling the amount of force required to move the cart. A directional sensor indicates the direction in which the cart is moving, and a velocity sensor indicates the velocity of the cart. Grip sensors on the handle detect the gripping force applied to the handle. A force sensor between the handle and the cart indicates the amount of force applied to the handle to move the cart. Data loggers connected to sensors record indications from the sensors. A computer is connected to the data loggers for accepting the recorded indications. A method of using the cart for measuring dynamic muscle function includes presetting the brake for a known resistance to movement, having a test subject move the cart along a predetermined course, measuring the force required to move the cart, measuring the velocity of movement of the cart, and measuring the direction of the cart.
