Abstract

Musculoskeletal disorders (MSDs) are commonly found among office workers, especially neck pain. This study evaluated the effectiveness of low-level laser therapy (LLLT) plus strengthening exercises on pain, neck flexibility, and quality of life in office workers with chronic non-specific neck pain. Thirty-six participants, aged between 25 and 40 years, were randomly divided into two groups: 18 received LLLT and strengthening exercises, while 18 received sham LLLT and the same exercises. The average body mass index (BMI) was 25.52 ± 5.08 in the LLLT group and 23.01 ± 3.34 in the sham group. Results revealed that the LLLT group experienced a significant reduction in pain compared to the sham group, as measured by a pain scale (p < 0.05). Both groups showed increased flexibility in all directions, but the LLLT group had significant improvements in flexion, right lateral flexion, and left rotation (p < 0.05). For quality of life, the LLLT group showed significant improvements in physical functioning, bodily pain, and general health on a standard quality-of-life questionnaire (p < 0.05). In conclusion, combining LLLT with strengthening exercises was more effective than sham LLLT and exercises in reducing pain perception, increasing neck flexibility, and improving quality of life in office workers with chronic non-specific neck pain.
