High-intensity Laser Therapy and Stretching Exercises for Chronic Non-specific Neck Pain: a Feasibility Study

Chronic non-specific neck pain (CNNP) poses a significant challenge in healthcare, sparking interest in conservative and innovative therapeutic options such as high-intensity laser therapy (HILT). While evidence of its efficacy in this specific context remains limited, there is a robust foundation supporting the use of HILT in managing chronic neck pain, demonstrating effectiveness in pain reduction and functional improvement. Therefore, the aim of this study is to evaluate the clinical response to HILT treatment in patients with CNNP, investigating its potential therapeutic benefits and adverse effects. The findings of this study will provide valuable insights into the clinical experience with HILT in this population, serving as a pivotal starting point for future research in this field. In a clinical trial, patients with CNNP will undergo a treatment regimen consisting of two weekly sessions of HILT and stretching exercises over four weeks. The study aims to assess primary outcomes such as resting pain intensity (RPI), movement pain intensity (MPI), and pain pressure threshold (PPT), measured using the numerical pain rating scale and algometry. Secondary outcomes will include cervical range of motion (CROM) and neck disability, assessed through inclinometry and the Neck Disability Index (NDI). Evaluations will occur post-treatment, with a follow-up assessment scheduled one month later.
