Physiology, Chapman’s Points

Excerpt

The intimate connection between the nervous system and the lymphatic system in both health and disease has long been acknowledged in osteopathic medicine. In fact, treatments such as rib raising and occipital inhibition have as their foundation this very principle. Though first described as neuro-lymphatic points by Frank Chapman, DO in the early 1900s, Chapman's points are now defined as organ-specific gangliform contractions associated with underlying visceral dysfunction. More specifically, Chapman's points present as smooth and discreetly palpable nodules located deep within the fascia in regions related by dermatome to the dysfunctional viscera. These points are sharp, pinpoint, non-radiating, and anatomically consistent between individuals.

Though initially considered somatic representations of neuro-lymphatic reflexes, the contributions of osteopathic physicians such as Charles Owens, DO, H.L. Samblanet, DO, and Paul Kimberly, DO, expanded the consideration of these nodules to be somatic manifestations of general visceral dysfunction, including of the lymphatics and endocrine glands. Eventually, these nodules were coined Chapman's points or Chapman's reflexes.

This article intends to expand on issues of concern regarding Chapman's points, their embryologic basis, mechanism of development, and function in clinical practice.
