Biophysical Factors in Range-of-Motion Exercise.

In brief: Studies of the physical properties of connective tissue have helped determine improved techniques for therapeutic range-of-motion exercise. Laboratory studies indicate that the best way to permanently lengthen connective tissue structures without compromising their structural integrity is prolonged, low-intensity stretching at elevated tissue temperatures and cooling the tissue before releasing the tension. This article provides some practical therapeutic guidelines for physicians, trainers, and therapists who prescribe range-of-motion exercise for both rehabilitation and physical conditioning.
