Dry Needling/IMS should definitely fall under the scope of practice of Physical Therapy with the proper education and training.  I can speak first hand at the difference this has made in my therapy and over all goals of being pain free and increased modility.  There is a huge difference between accupuncture and Dry Neeling/IMS.  I have found with Dry Needling/IMS, my physical therapist is able to get to the muscle and relax it to the point that I am in immediately relief of pain.  I bruise easily and with dry needling I have no bruises afterwards vs manually manipulating trigger points causing brusing and sensitivity.  In addition, once the therapist has completed the dry needling, I go to the gym and work with the PT techs to stretch reiforcing the dry needling treatment.  Anyone making a decision on this should experience first had the difference between accupuncture and DryNeedling/IMS.  I highly, highly recommend that this follow under the scope of practice of physical therapy.
