Summary

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.

Conditions

  • Myofacial Pain Syndrome

Interventions

PROCEDURE

IMES using IEP

First group (n=12) received IMES using inverse electrode placement. The needle electrode inserted into the paraspinal region was connected to the active or cathode pole of the electrical stimulator. The reference or anode pole of the electrical stimulator was connected to the electrode that was inserted into the MTrP area of the UT muscle. The muscle was stimulated for 10 min with a tolerable intensity in a single session to induce muscle relaxation

PROCEDURE

IMES using CEP

Second group (n=12) underwent IMES with conventional electrode placement. In this group, the cathode pole of the stimulator was connected to the needle inserted into the UT muscle, and the anode pole was connected to the needles of the paraspinal region of the cervical spine. Needle electrodes were connected using alligator clip connectors. The muscle was stimulated for 10 min with a tolerable intensity in a single session to induce muscle relaxation.

OTHER

Sham-IMES

Third group (n=12) received sham-IMES. Similar to the experimental intervention groups, the cathode pole of the stimulator was connected to the needle inserted into the UT muscle, and the anode pole was connected to the needles of the paraspinal region of the cervical spine. However, the delivered IMES was very minimal intensity
