Cervical myofascial pain (CMP) is a muscular-skeletal disorder that causes pain in the muscles and its surrounding connective tissue "known as fascia" in the neck region. The pain may be localized or widespread and can also be characterized by multiple trigger points. Trigger points are highly sensitive muscle focal that are painful to touch and refer pain to the surrounding area. The prevalence rate of CMP is 22-70%, and the age range is between 20–54 years more in women than men. Study proposed to confirm the efficiency of low laser therapy with a wavelength 830nm in improving cervical myofascial pain syndrome. This study was conducted on 40 patients with CMP both sex with their age from (20-60) years old. They were chosen from the outpatient physical therapy clinic of Benha Teaching Hospital. They were divided randomly into two groups equal in number: Group A (control group): received physical therapy sessions only (Isometric exercise and stretching exercises for cervical region) for 5 sessions per week for a period of 3 weeks. Group B (study group): received low level laser therapy (GA–As–Al diode laser device) with wavelength 830nm on three trigger points bilaterally of cervical region for 5 sessions per week for 3 weeks as well as the previous program of physical therapy in group A. In this study, visual analogue scale was used for measurement of pain intensity and goniometer instrument was used for measurement of active range of motion of cervical region for all patients of both groups before and after 3 weeks of the study. The results were statistically analyzed, as it was concluded that there is significance difference in both group after treatment in favor of group (B). This study concluded that low level laser therapy with wavelength 830nm improve pain and cervical range of motion in patient with cervical myofascial pain syndrome.
