Low back pain is one of the most debilitating and costly epidemics in industrialized society, comprising over 25% of all outpatient physical therapy visits with a notable increase expected over the next 15 years. Consequently, this course has been designed to provide an evidence-based approach to the evaluation and treatment of lumbosacral dysfunction. This two day lab intensive course incorporates medical screening procedures, differential diagnosis, muscle energy techniques, functional exercise prescription, mobilization and manual therapy of the lumbosacral complex. Evaluation and treatment is approached as a systematic process utilizing clinical reasoning and scientific evidence. Significant lab time allows each attendee to process, practice, and polish intervention techniques under the guided supervision of experienced manual therapists. The end result is the ability to immediately apply new skills upon return to the clinic.
