Abstract
BACKGROUND: Neck pain has a high prevalence and socioeconomic impact worldwide. The Back School consists of programs that include exercises and educational interventions to treat back pain. Accordingly, the main objective was to evaluate the effects of an intervention based on Back School on non-specific neck pain in an adult population. The secondary objectives were to analyze the effects on disability, quality of life and kinesiophobia. METHODS: A randomized controlled trial was conducted with 58 participants with non-specific neck pain divided into two groups. The experimental group (EG) carried out the 8-week programme based on the Back School, (two sessions per week, for a total of 16 sessions, lasting 45 min). Of all the classes, 14 had a practical focus (strengthening and flexibility exercises) and the other two had a theoretical focus (concepts of anatomy and healthy lifestyle). The control group (CG) stated that they did not vary their lifestyle. The assessment instruments were: Visual Analogue Scale, Neck Disability Index, Short-Form Health Survey-36 and Tampa Scale of Kinesiophobia. RESULTS: The EG reduced pain (-40 points, CI95% [-42 to -37], g = -1.03, p < 0.001), EG had less disability (-9.3 points, CI95% [-10.8 to -7.8], g = -1.22, p < 0.001), EG improved the physical dimension of the survey Short-Form Health Survey-36 (4.8 points, CI95% [4.1 to 5.5], g = 0.55, p = 0.01) but had not significant change in psychosocial dimension of the survey Short-Form Health Survey-36 and EG reduced Kinesiophobia (-10.8 points, CI95% [-12.3 to -9.3], g = -1.84, p < 0.001). The CG did not obtain significant results in any variable of the study. Significant differences in change between both groups were found on pain (-11 points, CI95% [5.6 to 16.6], p < 0.001, g = 1.04), disability (-4 points, CI95% [2.5 to 6.2], p < 0.001, g = 1.23), physical dimension of the survey Short-Form Health Survey-36 (3 points, CI95% [-4-4 to -2-5], p = 0.01, g = -1.88), and kinesiophobia ( 7 points, CI95%[-8.3 to -5.4], p < 0.001, g = 2.04), while no significant differences were found on psychosocial dimension of the survey Short-Form Health Survey-36 (-0.02, CI95% [-1.7 to 1.8], g = 0.01, p = 0.98). CONCLUSIONS: The back school-based programme has beneficial effects on pain, neck disability, the physical dimension of quality of life and kinesiophobia in an adult population with non-specific neck pain. However, it did not lead to improvements in the psychosocial dimension of the participants' quality of life. This programme could be applied by health care providers with the aim of reducing the severe socio-economic impact of non-specific neck pain worldwide.
