In 2006, Dallas chiropractor Dr. Francis X. Murphy put into practice a unique form of analysis and correction targeted at the condition known as Frozen Shoulder Syndrome (FSS). Since then, hundreds of patients with FSS have sought out Dr. Murphy for this treatment and have had their FSS successfully resolved. After two years of observation, study, and the assistance of many health care institutions and patients, a new understanding of the nature and causes of FSS has emerged and has been developed in the OTZ curriculum. FSS has been linked to certain neurological disorders which the OTZ diagnosis and treatment approach has also shown tremendous promise as well as generated new questions.
