Laser Therapy for Patients With Nonspecific Neck Pain

Background and Purpose: Neck pain is widespread and stands as the sixth most common cause of disability globally. While laser therapy has been used for many years to treat non-specific neck pain (NNP), there is still a shortage of research directly comparing different laser modalities. The aim of this study was to evaluate and compare the therapeutic effectiveness of low-level laser therapy (LLLT) and high intensity laser therapy (HILT) in managing NNP. Methods: sixty patients diagnosed with NNP were equally randomized into three groups. HILT group received 10 weeks of HILT, LLLT group received 10 weeks of LLLT and a control group that received a home program. Outcome measures were evaluated at baseline and after the intervention period and included pain intensity, neck disability, active cervical range of motion (ROM), and quality of life.
