The only this that is similar between trigger point dry needling and acupuncture is the needle.  Otherwise the philosophy behind the 2 techniques are completely different.  Trigger point dry needling focuses on targeting specific muscles that can lead to pain and looks to minimize the presents of active trigger points which have been associated with various types of pain.  Acupuncture focuses on meridians and energy flow to restore balance within the body's system.  These are 2 techniques that can treat the same conditions and if a physical therapist or acupuncturist goes through the formal education to perform those techniques, then why not.  It has been establish that physical therapist are the leaders in understanding anatomy and kinesiology.  And since neither an acupuncturist or a physical therapist has x-ray vision, each possess the necessary skills to perform the task of trigger point dry needling as along as advance education or certification through courses has taken place.  A physical therapist should not be performing acupuncture without an acupuncture license.  Trigger point dry needling is not acupuncture, it is a technique. 

Each practitioner should look to expand his or her knowledge to best help clients or patients.  This should not be a battle about who owns the rights to perform a technique but rather a way to create unity across all health care fields for best practice.  Best practice includes providing the appropriate type of care, at the appropriate time for each and every client/patient. 

I support the use of trigger point dry needling for physical therapist.  Hope you can do the same.
