The effect of exercise on health-related quality of life in persons with musculoskeletal pain: A meta-analysis of randomised control trials.

OBJECTIVES
Exercise has positive effects on musculoskeletal pain. In this project, the impact of exercise was studied on improving health-related quality of life in persons with musculoskeletal pain.


METHOD
The study design was a systematic review and meta-analysis. A search was conducted to find original studies in four sources, including PubMed, Web of Science, the Cochrane Library and Scopus, and this search was limited to the original articles published until April 2021, which were in English. For each study, the effect size was calculated. The analysis was based on the random-effects method.


RESULT
Twenty-Seven randomised control trial studies were included in the meta-analysis. The total population of participants in the meta-analysis was 1927 persons. Exercise improves health-related quality of life in these persons and the hedges' g was 0.66 (95% CI = 0.38-0.94; I2  = 88.29%).


DISCUSSION
Overall, based on the findings, exercise is associated with improving the health-related quality of life of persons with musculoskeletal pain, and therefore the health implications of this finding are beneficial to the general population and professionals.
