In the current clinical and scientific reality, conservative treatment is the most coherent clinical management with a view to the proper rehabilitation of patients with chronic neck pain, with a trend towards the use of therapeutic exercise. However, some uncertainty about the effectiveness of therapeutic exercises still remains, requiring further studies with high methodological rigor, especially with regard to multimodal treatment, such as the combination of therapeutic exercises with photobiomodulation. Thus, the objective of this project is to evaluate the effects of adding photobiomodulation to a program of specific therapeutic exercises for the treatment of individuals with chronic non-specific neck pain. For this, 60 participants will be randomized into two groups: therapeutic exercise group + photobiomodulation (n = 30), and therapeutic exercise group (n = 30). There will be 10 treatment sessions and participants will be evaluated before, after the 10 sessions, and 4 weeks after the end of treatment using the Numerical Pain Scale, Neck Disability Index, Catastrophic Thoughts about Pain Scale, and Tampa Kinesiophobia Scale. In the statistical analysis, a linear mixed model will be applied, considering the interaction between the time and group factors. Finally, the addition of photobiomodulation to a therapeutic exercise program is expected to generate clinical improvements for patients with chronic neck pain.
