Visceral Manipulation was developed by French Osteopath, Jean-Pierre Barral. The visceral system relies on the interconnected synchronicity between the motions of all the organs and structures of the body. At optimal health, the relationship between the organs (viscera) and structures of the body (muscles, membranes, fasciae and bones) remains stable despite the bodyâ€™s endless varieties of motion. But when one organ canâ€™t move in harmony with its surrounding viscera due to abnormal tone, adhesions or displacement, it works against all the bodyâ€™s organs and structures. This disharmony creates fixed, abnormal points of tension that the body is forced to move around. That chronic irritation, in turn, paves the way for disease and dysfunction.
