Cranial Adjusting Research Library

This page is meant to be a living resource rather than a one-time article. As I come across relevant research, I’ll add it here, organized by category, so readers who want to go deeper have a starting point.

Cranial anatomy and biomechanics

Research on the structure of cranial bones and sutures, and biomechanical studies measuring cranial deformation under load. See cranial bones anatomy and cranial sutures for summaries.

Cranial manual therapy: reliability and effectiveness

Systematic reviews and meta-analyses examining the diagnostic reliability and clinical effectiveness of cranial osteopathy and craniosacral therapy. See what the evidence shows for a summary of the current state of this research.

Manual muscle testing and Applied Kinesiology

Research on the reliability of manual muscle testing, including recent systematic reviews specific to Applied Kinesiology-style testing procedures.

Sensory input and motor function

Neurophysiology research on how sensory input — including from the craniofacial region — can influence motor output elsewhere in the body, and how manual and mechanical stimulation can affect muscle activation.

History of cranial techniques

Cranial work actually developed along two separate historical tracks. See the history of the endonasal cranial technique, from Finnell and Stober to CFR, drawn primarily from André Saine’s 2025 practitioner’s manual and 2026 historical article; and the history of direct cranial manipulation, the older, separate tradition associated with Sutherland, Cottam and Toftness.
