I understand why physical therapists would like to add "needling" into their scope of practice. It would enhance their practice and probably give better outcomes. However, they do not receive enough training for them to safely needle their patients and could cause harm to the public. For more thoughtful information on the subject, one should refer to http://www.liveoakacupuncture.com/dry-needling/
Physical therapist should build relationships with local acupuncturists and refer their patient to them for proper care. In the medical world, we are forced or refered to specialists for a reason, and in this instance it should be the same.
