<qa>  What is the name of the skilled intervention that uses acupuncture filiform needles?Dry Needling DN is a skilled intervention that uses acupuncture filiform needles that are inserted into myofascial trigger points or other tissues underneath the skin. It is used to treat myofascial or neuromusculoskeletal pain and to improve movement impairments. Although more and more physical therapists add this treatment tool to their skill box, there is uncertainty about its working mechanism and its efficacy. The latter is partially due to the challenging task of finding and using a true control or sham treatment. The investigators will use blunted needles, which will not perforate the skin, as sham treatment.
