Dual Frequency Low-Level Laser Therapy in Myofascial Trigger Points of Upper Trapezius
Sponsor: University of Lahore
Summary
The goal of this clinical trial is to determine whether dual frequency low-level laser therapy can reduce pain, improve function, and increase neck movement in patients with myofascial trigger points in the upper trapezius muscle. The study includes men and women aged 20 to 55 years who have been diagnosed with upper trapezius myofascial pain syndrome. The main questions it aims to answer are: * Does dual frequency low-level laser therapy reduce pain more effectively than single wavelength laser therapy? * Does dual frequency low-level laser therapy improve functional ability and cervical range of motion more than other treatments? Researchers compared three groups of participants receiving different treatments to evaluate their effects. Participants were randomly assigned to one of three groups: * Group A received red wavelength low-level laser therapy with conventional physiotherapy * Group B received infrared low-level laser therapy with conventional physiotherapy * Group C received dual frequency low-level laser therapy with conventional physiotherapy All participants received treatment twice weekly for four weeks. Conventional therapy included stretching exercises, strengthening exercises, and postural correction.

Interventions
Red Low-Level Laser Therapy
Red wavelength (660 nm) low-level laser therapy was applied to upper trapezius trigger points at a dose of 5 J/cm², frequency 9-10 Hz, for 60-100 seconds per point, twice weekly for four weeks.
Infrared Low-Level Laser Therapy
Infrared wavelength (830 nm) low-level laser therapy was applied to trigger points at a dose of 5 J/cm² for approximately 3 minutes per point, twice weekly for four weeks.
Dual Frequency Low-Level Laser Therapy
Dual frequency laser therapy combining red (660 nm) and infrared (830 nm) wavelengths was applied sequentially to trigger points with a dose of 5 J/cm² per wavelength, twice weekly for four weeks.
Conventional Therapy
Conventional physiotherapy included stretching exercises, isometric strengthening, and postural correction techniques.
