There are many similarities and differences between trigger point dry needling and acupuncture. Licensed physical therapists in a growing number of states can use trigger point dry needling under the scope of their practice. Physical therapists at One on One Physical Therapy are not licensed acupuncturists and do not practice acupuncture. (Although we do have licensed acupuncturists on staff.) In contrast to most schools of acupuncture, trigger point dry needling is strictly based on Western medicine principles and research.
