Hand-over-hand assistance is provided by placing an object in the person's hand, firmly grasping their hand and the object and guiding the arm movement, i.e. you do 70% to 90% of the work. Range of motion, trunk stability and sustained attention are the benefits. Washing, wiping, painting, and rubbing are familiar movements with obvious effects. Hand-over-hand techniques do not need to be limited to feeding and grooming and their attention may be sustained longer, and with more effort on their part, doing something else with the metronome.
