Osteopathic Lesion Theory — Still Lesion Map
Osteopathic Lesion Theory — Still Lesion Map is a Modern / Somatic manual therapy — Osteopathic lesion theory body system as transmitted through the lineage A.T. Still framed osteopathy as an integrated approach in which structure, function, circulation, and the body’s self-regulation are considered together. This entry translates that doctrine into a modern teaching map of structural and somatic–visceral examination regions; Still’s works do not supply a canonical six-to-eight-point front-view diagram.. This page lists every point in the system with sourced placements and links to cross-tradition correspondences curated for The Body Spiritual.

- A.T. Still, The Philosophy of Osteopathy (1899, published by the author) — Chs. 1–3 set out Still’s osteopathic philosophy, including the body as an integrated whole and the relation of structure, function, and circulation; these chapters support the doctrine, not a fixed six-zone chart.
- A.T. Still, Osteopathy: Research and Practice (1910, published by the author) — Chs. 1–2 describe Still’s research-and-practice rationale for osteopathic examination and treatment; the source does not prescribe the front-view coordinates used here.
- Carol Trowbridge, An American Original: The Life of A.T. Still and the First Osteopathic School (Devin-Adair, 1991) — Historical study of Still, early osteopathic institutions, and the changing meanings of lesion and osteopathic practice.
Known lineage variants
- Still’s lesion language changed across early osteopathic writings and later schools; no single primary text establishes the exact eight loci or the two visual routes rendered here.
- The cranial, spinal, and visceral markers are editorial projections onto a front silhouette. Anatomical right is x < 0.5; wide uncertainty radii signal that these are regions of examination rather than palpable coordinates.
- Osteopathic lesion theory is a historical clinical framework, not a substitute for contemporary diagnosis. The map makes no efficacy, safety, or disease-causation claim.

Frequently asked
What is Cranial base lesion focus?
Still’s whole-body philosophy supports examining the cranium in relation to the rest of the body. This front-view mark is an editorial cranial-base projection, not a claim that a discrete lesion can be seen at this coordinate.
What is Cervical spine lesion focus?
The cervical region is rendered as a representative site for osteopathic structural examination. Still’s texts discuss relationships among structure and function, but they do not establish this single point as a universal lesion location.
What is Upper thoracic lesion focus?
This upper-thoracic mark represents a manual-examination region where rib, vertebral, and respiratory relationships may be considered together. Its position is a diagrammatic grouping, not an anatomical diagnosis or a prescribed treatment target.
What is Lower thoracic / diaphragm focus?
The lower thoracic focus keeps the diaphragm and thoracolumbar transition visible in the lesion map. The front projection is an editorial teaching proxy and does not claim that a lesion has one fixed depth or side.
What is Lumbar spine lesion focus?
This point marks the lumbar region as a common structural relationship in the osteopathic reading of posture and movement. It is not a claim that osteopathic lesion theory reduces to low-back pathology or that every patient shares this finding.
What is Sacroiliac lesion focus?
The sacroiliac focus represents the pelvic ring as a region of load transfer and positional assessment in manual practice. Coordinates are a front-view editorial projection; they are not a radiographic or anatomical lesion map.
What is Visceral relationship — upper abdomen?
This upper-abdominal point makes the osteopathic tradition’s interest in visceral and somatic relationships visible without asserting a specific organ lesion. It is a broad region marker assembled from modern teaching language, not a canonical Still coordinate.
What is Visceral relationship — pelvis?
This broad pelvic marker represents visceral–somatic relationships at the lower trunk in a teaching diagram. The source lineage does not provide a fixed front-view visceral map, so the location and uncertainty are intentionally wide.
