Dual Frequency Low-Level Laser Therapy in Myofascial Trigger Points of Upper Trapezius

The goal of this clinical trial is to learn if dual frequency low-level laser therapy (DF-LLLT) works to reduce pain and improve neck function in adults with myofascial trigger points in the upper trapezius muscle. It will also determine whether DF-LLLT improves cervical range of motion. The main questions it aims to answer are: i)Does DF-LLLT reduce pain intensity on the Visual Analog Scale (VAS) more than sham laser therapy? ii)Does DF-LLLT improve functional status (Neck Disability Index) and cervical range of motion more than sham laser therapy? Researchers will compare DF-LLLT plus conventional therapy to sham laser plus conventional therapy to see if DF-LLLT has greater therapeutic effects. Participants will: 1. Receive either DF-LLLT or sham laser therapy twice weekly for 4 weeks 2. Perform a standardized stretching and strengthening exercise program for the neck and shoulders. 3. Attend clinic visits at baseline, week 2, and week 4 for assessments of pain, function, and cervical mobility.
