Chapman reflex points

Chapman reflex points refer to nerve gangliform contractions located deep to the skin and subcutaneous tissue, most often within the deep fascia or periosteum of the bone. These neurolymphatic points are found at specific areas of the body that correspond to visceral dysfunctions (also termed viscerosomatic reflexes). Pain at any of these points represents potential internal dysfunction or pathology of a specific organ. They can be felt as small, discrete, and smooth palpable nodules, approximately 2 mm in diameter. Although Chapman points are typically diagnostic, they may also be manipulated for therapeutic purposes.

• First described by Dr. Frank Chapman in the 1920s as “gangliform contracted lymphoid tissue nodules”
• Arise due to lymphatic congestion or blockage from nerve sheaths at free nerve endings
• Primarily correspond to the sympathetic fibers of the autonomic nervous system running along dermatomal patterns
• Round, smooth, discrete and tender palpable nodules (∼ 2 mm in diameter)
• Associated with visceral dysfunctions
• Should not be confused with myofascial trigger points (MTrP) or Jones (counterstrain) tender points
• Located in either the deep fascia or periosteum of bone
• Corresponding anterior and posterior points
  • Anterior points used diagnostically
  • Posterior points used therapeutically

General considerations

• Typically utilized selectively for diagnostic purposes
• Somatic manifestations clue into visceral dysfunctions → Conduct further evaluation of corresponding Chapman points.
• Findings
  • Reflex points can be slightly painful to extremely tender without radiation → supports potential visceral dysfunctions of corresponding organ
  • Nontender reflex points by themselves are inconsequential.

Treatment

• Pelvic diaphragm release
• Apply gentle pressure in concentric circular motions for 20–60 seconds (or until the point softens and pain is reduced).
• Associated somatic dysfunctions may also be treated separately.
