Visceral organs have two types of motion; mobility and motility. Mobility is movement of the organs in response to movement of the body. Motility is movement that is inherent to the organ itself. There should be no restriction of visceral organ motion, in either mobility or motility. Restriction and/or abnormal motion implies functional impairment of the organ.
We find that musculoskeletal pain can often times be a result from restricted viscera. In order to improve our patient's pain we must address the mobility and motility of the viscera.
