Dry needle is good and it is acupuncture. Acupuncturist need about 3000 hours trainning in USA and about 6000 hours trainning in China. If PT want to practice Dry needle, they should receive at least 2000 hours trainning and pass the NCCAOM examination. Then they can apply for the Acupuncture license to treat the patient. In USA even MD need 300 hours trainning to obtain the Acupuncture license and most of the MD with Acupuncture license just hire the licensed Acupuncturist to work for them because their trainning is no enough to practise the acupuncture.
