I recently took an advanced spine course from the McKenzie Spine Institute in Harrisburg, PA. It is based on a comprehensive evaluation of your movement patterns. The approach attempts to establish which patterns can reduce the patient symptoms for various musculoskeletal conditions including the extremities. Some of the things that I like about the philosophy is that it uses a system, empowers the patient, and is research based. One of the common misconceptions is that everyone for the treatment of the spine gets a prone extension exercise. A true evaluation from a McKenzie physical therapist provides exercises to a patient only on the basis of the patients positive response to a particular movement.
