The efficacy of thread embedding acupuncture on pain score, neck disability index, and pressure pain threshold for myofascial pain therapy in the upper trapezius muscle

Myofascial pain characterized by myofascial trigger point (MTrP) is a common cause of musculoskeletal pain and the main cause of neck and shoulder pain in the working population. Thread embedding acupuncture (TEA) is a new modality that can provide long-term stimulation to prolong the same therapeutic effect as conventional acupuncture. This study aimed to determine the effect of TEA therapy on pain score, neck disability index (NDI), and pressure pain threshold (PPT) for myofascial pain in the upper trapezius muscle.
