Document Summary

Specificity: to increase rom of a particular joint, select exercises that stretch the appropriate muscle groups. Overload: to improve rom at a joint, your client must overload the muscle group by stretching the muscle beyond their normal resting length but not beyond pain-free rom. Inter-individual variability: pain-free rom varies among individuals, depending on their stretch tolerance and their perception of stretch and pain (stretch tolerance: the amount of resistive force to stretch within target muscles that a person can tolerate before experiencing pain) Progression: increase the total time of stretching by increasing the duration or number of repetitions of each stretch in order to ensure the overload required for further rom improvements. Ballistic: jerky, bouncy movements, lengthening the target muscle. Static use slow, sustained muscle lengthening to increase rom. Pnf maximal or sub-maximal contraction or target and opposing muscle groups followed by a passive stretching of the target muscle group. Active client move body part without external assistance.
