MYOFASCIAL PAIN, NECK DISORDER
The structural arrangement of the cervical spine makes it susceptible to mechanical changes,Myofascial trigger points (MTrPs) play a significant role in the context of mechanical neck pain.Numerous manual and electrotherapy options, including TPI,Manual therapists increasingly turn to post-isometric relaxation (PIR) to address tight muscles and impaired joint function in myofascial pain syndrome.Spinal manipulation is a commonly used therapy for neck disorders and is effective.Recent research demonstrates PIR’s effectiveness in myofascial pain, stiffness, and mobility management in mechanical neck pain patients.Various studies have demonstrated the efficacy of single interventions like cervical mobilization and PIR in addressing neck pain, cervical range of motion (ROM), and functional limitations linked to mechanically induced pain from MTrPs.
