Medical acupuncture is used by GP's and physios etc, and is not bases on the old concepts but on a western interpretation of body function, and is used primariliy for pain relief, rather than say, insomnia or infertility. Training can be as short as 24 hours over 2 weekends. Dry needling is a term used by this group to differentiate from injections- it generally refers to something called "Trigger point" acupuncture.
