Abstract: BACKGROUND: Red light therapy has the non-invasive and cost-effective characteristics, and is widely used in various acute and chronic pains in clinic. However, currently, the phototherapy equipment used in clinic is expensive and has certain site limitations, so it is necessary to explore more convenient and economical phototherapy applications. 
OBJECTIVE: To observe the clinical efficacy of a self-developed photon cervical vertebra massage instrument for chronic neck pain. 
METHODS: From November 2022 to February 2023, 24 patients with chronic neck pain were recruited from the Department of Rehabilitation Medicine, Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, including 18 females and 6 males, with a mean age of (29.67±6.40) years. The body mass index was (21.39±3.52) kg/m2. Photon cervical vertebra massage instrument was used twice a day for 20 minutes each time for four weeks. The changes in visual analog scale score, pressure pain threshold, neck active activity, neck disability index, and Pittsburgh sleep quality index were observed before, after 2 and 4 weeks of treatment.
RESULTS AND CONCLUSION: (1) Compared with before treatment, after four weeks of treatment, visual analog scale score, pressure pain threshold, neck disability index, and Pittsburgh sleep quality index were all improved (P < 0.05), while some cervical motion (extension, left and right rotation) improved (P < 0.05) after 4 weeks of treatment. (2) Bilateral visual analog scale scores, left trapezius muscle pressure pain threshold, C5C6 pressure pain threshold, and neck disability index improved after 2 weeks of treatment (P < 0.05). (3) It is indicated that the application of photon cervical vertebra massage instrument can improve the pain score, muscle tenderness, sleep quality, functional level, and partial active activity of patients with chronic neck pain in a short period, and is a convenient, effective, and safe treatment method.
