Any medical practicitioner can choose to take courses that teach them skills over and above what they have learned in their basic training in school which got them their license.  Trigger point Dry Needling is one that is taught very skillfully and can be practiced by a licensed physical therapist.  It is not accupuncture nor has any physical therapist ever said that it is accupuncture.  There shouldn't be a problem here between the two professions as we are practicing two completely different techniques which are all meant to benefit the patient.  PT's should be allowed to do dry needling.
