This week Travis welcomed Rett Nicolai to the show. Rett is a physical therapist who specializes in advanced manual therapy. He has gone through advanced training and now instructs residents and fellows seeking further education in manual therapy. It has enlightened him with a deeper understanding of not only anatomy and how the body works, but more specifically how the nervous system has control over how the body functions, or doesn’t. He understands how the sympathetic nervous system can interfere with the regular functions of the all components of the body, from muscles and joints to organs and tissues.
