The study was designed to compare the effectiveness of eight-week stretching exercise combined with back care education, lumbar stabilization combined with back care education and back care education on kinesiophobia and health-related quality of life in quarry workers with work-related low back pain (WRLBP). Materials and Methods: The randomized clinical trial involved 96 quarry workers with WRLBP randomly assigned into Stretching Exercise with Back Care Education Group (SEBCEG), Lumbar

... sation Exercise with Back Care Education Group (LSEBCEG) and Back Care Education Group (BCEG). Participants kinesiophobia was assessed using Tampa scale of kinesiophobia while health-related quality of life was assessed using WHO health-related quality of life. Participants were treated twice weekly and evaluated at baseline, week 4 and week 8 of the study. Data were analysed using descriptive statistics, ANOVA, Friedman's ANOVA and Kruskal-Wallis test at α 0.05. Results: Eighty-six participants completed the study with no significant differences in demographic and clinical characteristics between the three groups at baseline. Participants in the SEBCEG demonstrated more significant reductions (p < 0.05) in kinesiophobia and more improvement in quality of life than those in both LSEBCEG and BCEG at the end of week 8 of the study. There were significant within-group improvements (p < 0.05) in all variables for the three groups thus indicating the effectiveness of each intervention. Conclusion: Stretching exercises are better than lumbar stabilisation exercises and back care education in reducing kinesiophobia and improving health-related quality of life pain in individuals with WRLBP.
