Dry Needling and acupuncture are the same modality. It doesn’t matter the paradigm 

If I prescribed physical therapy exercises but said I wasn’t doing physical therapy because physical therapists look at muscles and acupuncturist look at energy it would working outside my scope of practice. 

This is exactly what physical therapists are doing they’re saying dry needling is different than Acupuncture because dry needling focuses on the muscles and Acupuncture focuses on energy. 

Regardless of what you’re looking at the techniques are exactly the same.
