Which mechanism best explains how OMM can improve lymphatic drainage?

• A. By stimulating the sympathetic chain ganglia.
• B. By addressing fascial restrictions and improving diaphragmatic and thoracic mobility to enhance lymphatic flow.
• C. By increasing rib cage rigidity.
• D. By shortening the thoracic duct.

Answer: (B)

Lymph drainage relies on external forces to move lymph through the vessels—primarily the rib cage and diaphragm acting as pumps, plus the surrounding fascia that needs to be free to slide and compress. Osteopathic manipulative treatment helps by releasing fascial restrictions and improving the movement of the diaphragm and thoracic cage. When the diaphragm and rib cage can move more freely, the thoracic cavity can generate better suction and propulsion for lymph, boosting drainage through the thoracic inlet and related lymphatic pathways. Stimulation of the sympathetic chain ganglia would alter autonomic tone but isn’t the main driver of lymph propulsion. Increasing rib cage rigidity would reduce the mechanical pumping action, hindering drainage. Shortening the thoracic duct would directly impede lymph flow, which is counterproductive.
