Biodynamic Osteopathy was developed by James Jealous and is based on W.G. Sutherlands' Cranial Osteopathy
J. Jealous added another element termed 'the Neutral'. This neutral is achieved without any force or interference applied by the osteopath. The osteopath is there to facilitate the inherent Breath of Life, the life force within the Primary Respiratory Mechanism (PRM).
The neutral can be seen as the midpoint between (thoracic) breathing in and breathing out cycle but then within the PRM. In disease, with injuries,... this PRM cycle is disregulated and causes interference in the healing process.
