Background Evidence is mixed regarding the effect of exercise programs on improving musculoskeletal symptoms and quality of life. Previous meta-analyses have not focused specifically on the musculoskeletal symptoms. Therefore, this meta-analysis aimed to evaluate the effect of exercise on these outcomes in breast cancer survivors taking aromatase inhibitors. Methods PubMed, CINAHL, EMBASE, Web of Science, Wan Fang, CNKI, VIP, and CBM were searched for randomized control trials or quasi-experimental studies from the establishment of the database to May 2019. Studies comparing exercise programswithusualcareamongbreastcancersurvivorstakingaromataseinhibitorswereincluded. Theprimaryoutcomewasthe degree of musculoskeletal symptoms, as assessed by scores of pain, stiffness, and grip strength. The secondary outcome was the total quality of life score. Results A total of 9 studies involving 743 participants were included. Exercise programs were more effective than usual care in improvingmusculoskeletal symptomsamongbreastcancerpatientstakingAIs. The subgroupscoresofpain(SMD= -0.46,95% CI -0.79 to -0.13, P = 0.006), stiffness (SMD = -0.40, 95% CI -0.71 to -0.08, P = 0.01), and grip strength (SMD = 0.43, 95% CI 0.16 to 0.71, P = 0.002) benefited from exercise interventions. Similar effects were found for the quality of life scores (SMD = 2.24, 95% CI 0.28 to 4.21, P = 0.03). Conclusions Results indicate that exercise relieves musculoskeletal symptoms and improves quality of life, which can be used to motivate patients to exercise actively under professional guidance. Due to a small sample size, further research is required to ensure the effectiveness of exercise on musculoskeletal symptoms and quality of life.
