Athletic trainers should not be performing acupuncture or dry needling due to their lack of specialized education and training required. Acupuncturists have extensive training, typically 4 years of education and over 800 hours of clinical experience to master the techniques. Dryneedling is marketed as a new technique but it's simply a new name for acupuncture but lacks the depth, educational, techniques and safety protocol. It's a shoot / needle and spray, hope for a trigger point system. when there is so much more behind proper needling techniques and point location education needed. Each point on the body has an effect even though PTs and western doctors think it's just a muscle, just a needle. 

Athletic trainers should not be stepping into this field. Refer to a Licensed Acupuncturist instead.
