Abstract
This article discusses tonal asymmetry as an adaptation to spinal and cranial dysfunction and examines the use of holistic tonal assessment as a tool to guide and prioritise the application of Bowen therapy. The authors introduce the concept of the‘ Window of Symmetry’ and outline its clinical value in helping to transition patients from a state of dysfunction and adaptation to a phase of global reorganisation and healing. Possible mechanisms of action involving the autonomic nervous system are explored.
Introduction
The term, Bowen Therapy, is commonly used to describe several interpretations of remedial body work that are based on the methods used by an informally trained Australian osteopath named Thomas Ambrose Bowen 1( 1916-1982). The most simplistic interpretations of Bowen Therapy employ standardised sequences of predetermined‘ moves’ to elicit a therapeutic response, while more complex interpretations adopt a more patient-specific approach, whereby interventions are informed by clinical assessment. 1
We argue that the integration of holistic assessment methodologies into Bowen Therapy practice offers considerable potential to individualise treatment and enhance clinical outcomes. To this end, we outline a model of holistic tonal assessment consistent with traditional osteopathic principles and informed by the observation and interpretation of craniospinal dynamics.
Background The Dura Mater The Central Nervous System( CNS), including the brain and the spinal cord, are protected by the bones that make up the skull and the spine. These bony structures are specialised to allow for movement as well as protection. The close relationship between these bony structures and the CNS is mediated and facilitated, in part, by a sensitive connective tissue matrix, which forms a substantial interface between them – a large and extensive fascial structure known as the dura mater. 2-5
The outermost layer of the meninges, the dura mater is a tough protective covering that surrounds the brain and spinal cord. It provides additional support and protection to the CNS, particularly to protect it from mechanical injury. Anatomically, it is firmly attached to the bones of the cranial base( including the occiput, sphenoid, and temporal bones), to the upper cervical regions( particularly C2 and C3), to the sacrum( around S2), and to the coccyx( via the filum terminale). 2, 3, 6 Its fascial nature could be described as extensive
