Cranial Rhythmic Impulse (CRI) or Primary Respiratory Mechanism (PRM), a rhythm felt by Osteopaths at the surface of skin, is fundamental concept that some them in their practice for diagnosis and treatment. However, physiological basis this phenomenon remains unclear. Sutherland, founder cranial osteopathy, proposed 1939 theory remained dogmatic, despite scientific advances refuted it. Since 1990, osteopaths have tried to find better explanations, such as those presented previous systematic review. In narrative review, we first revisit each pillar Sutherland’s theory, analyzing light latest studies assess whether contemporary research supports challenges his ideas. After showing model inconsistent with current evidence, explore knowledge mechanisms underlying PRM/CRI. The most plausible hypothesis explain based on variation extracellular matrix fascial texture, influenced rhythmic oscillations blood pressure (Traube Hering Mayer waves), interplay other rhythms (ventilation, baroreflex, heart rate variability…). Finally, discuss relevance practical applications PRM osteopathy. While Sutherland's continues hold sway mainstream beliefs, literature has increasingly emphasized autonomic system activity leading hypothesis. This analysis underscores need paradigm shift regarding CRI/PRM arguing clearer communication aligned evidence.
