The prevalence of myofascial pain ranges from 30 to 93% and can result in sensorimotor and autonomic deficits. In routine neuromuscular electrical stimulation, conventional electrode placement (CEP) and inverse electrode placement (IEP) are used to deliver electrical stimulation for pain modulation. However, Whether pain modulation can be achieved better from the intramuscular electrical stimulation (IMES) using the inverse electrode placement (IEP) or the conventional electrode placement (CEP) is still an open issue. Thus, current study's aim to compare the effects of IMES using IEP and CEP, and sham-IMES on pressure pain threshold (PPT), EMG activity, upper trapezius (UT) muscle length and pain severity in the UT muscle with myofascial trigger points (MTrPs) among young adults.
