Efficacy of balance training for hip fracture patients: a meta-analysis of randomized controlled trials

BackgroundTo investigate whether the clinical effects of balance training were improved in hip fracture patients.MethodsElectronic databases which included PubMed, Embase, Web of Science, and the Cochrane Library up to December 2018 were searched. High-quality randomized controlled trials (RCTs) and prospective clinical controlled studies were selected based on inclusion criteria. Stata 12.0 was used for the meta-analysis. Standard mean difference (SMD) with 95% confidence interval (CI) was used to assess the effects.ResultsFinally, 9 studies with 872 patients (balance training=445, control=427) were included in our meta-analysis (published between 1997 and 2018). Compared with the control group, balance training group showed a significant increase in overall function (SMD=0.59, 95% CI [0.25, 0.93], P=0.001), gait speed (SMD=0.63, 95% CI [0.19, 1.07], P=0.005), lower limb strength (SMD=0.73, 95% CI [0.50, 0.95], P=0.000), activities of daily living (ADLs) (SMD=0.97, 95% CI [0.61, 1.34], P=0.000), performance task scores (SMD=0.41, 95% CI [0.21, 0.61], P=0.000), and health-related quality of life (HRQoL) scores (SMD=0.32, 95% CI [0.16, 0.47], P=0.000).ConclusionsOur meta-analysis revealed that the balance training group has improved overall physical functioning, gait, lower limb strength, performance task, and activity of daily living than the control group. More high-quality and large-scale RCTs are needed to identify the optimal regimen of balance training after hip fracture.
