Shirley Sahrmann, PT, PhD. is a world renowned physical therapist and house hold name in connection with movement system impairment syndromes (MSI). Shirley has been shaping the education system in the States for many decades and continues to be active as a clinician and teacher at Washington University. Recently, I attended her lower quadrant course on MSI of the lumbar spine and the influences of and relationship to the hip. This blog is an overview of the key messages I took away from the course.
