Prevalence of Chapman Reflex Points in Medical Students and Their Association With Visceral Symptoms

Study Summary

Chapman Reflex Points (CRPs) are small palpable nodules found within connective tissue that have traditionally been associated with dysfunction of internal organs and the autonomic nervous system. However, little is known about how commonly these findings occur in healthy individuals or whether they are associated with symptoms experienced by otherwise healthy people. The purpose of this study is to determine the prevalence of Chapman Reflex Points in young healthy adults and to evaluate whether the presence and distribution of these points are associated with self-reported visceral symptoms. Participants complete a standardized health questionnaire regarding recent and recurrent symptoms and undergo a blinded physical examination of established Chapman Reflex Point locations performed by a trained investigator. The results of this study may improve understanding of the physiological mechanisms underlying Chapman Reflex Points and help clarify their potential role in preventive osteopathic assessment and early identification of altered autonomic, lymphatic, fascial, or neuroendocrine function.

Primary Outcome

The prevalence and distribution of Chapman Reflex Points identified during a standardized palpatory examination of established Chapman Reflex Point locations performed by a blinded trained investigator. The total number of Chapman Reflex Points observed per participant was recorded and summarized using descriptive statistics.
