What is full range of motion (ROM) and why is it important?
A. Full range of motion refers to taking the muscle or joint through a full excursion of its possible movement. This would include allowing a muscle to move from its shortest length to its longest length or a joint through its full rotation. All muscles have a position where the muscle can generate optimal force within the range of motion (ROM). Working through the full range of motion strengthens the weaker ends of the muscle, preparing them for activities of daily living (ADL). An advantage of the dynamic pulley system is that it is best designed to provide resistance through the full range of muscle and joint motion.
