SYSTEMIC in its approach to chronic or acute pain and tension, the entire pattern of musculoskeletal involvement is assessed and treatment strategies formulated. The commonality of SDTT with other types of physical therapy lies only probably, in its manual delivery of the treatment. Everything else is based on principles of "systemic" structural deviations with all of the three dimensional implications that are inherent in such patterns. Key compensation sites of the body, believed to condition and underlie the patient's symptoms, are determined and addressed each session.
