Tools to help people get better should never be "owned" by any one group of healthcare professionals.  We are all in the healthcare field for the benefit of the patient.  As part of their entry level education, physical therapists are well educated in anatomy and therapeutic treatment of the body.  Physical therapists who perform dry needling supplement that knowledge by obtaining specific postgraduate education and training.  Physical therapists are therefore well trained and educated to perform dry needling with no increased risk to the patient compared to other healthcare professionals.
