Dry needling and trigger point are belonge to acupuncture.  They are called ASHI or Pain point. Also we offen use Trigger Points for Tueina, acupressure or massage. We have go to Chinese Medical school for three years study and pass the board exam to get a license to do so. For PT only use 60 hours training and can use needling to patiens ? This is worry! Dry needling by PT should STOP!
