The physician providing treatment will use, depending on his professional judgment for each subject, one of four treatment modalities: (1) soft-tissue stretch, (2) myofascial release, (3) muscle energy, or (4) functional (indirect) method. These modalities are standard to the care and practice of osteopathic manual medicine, they are taught in the Osteopathic curriculum, and they are practiced each day at the Michigan State University Clinical Center.
