Effect of Balance Training After Hip Fracture Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Studies.

Background
Although balance impairment after hip fracture surgery (HFS) can constitute a long-term problem of limiting mobility and increasing the risk of falls in older adults, little is known about the effect of balance training (BT) on physical functioning after HFS. Thus, we performed a meta-analysis to evaluate whether BT improved the overall physical functioning of patients after HFS.


Methods
We searched the PubMed-Medline, Embase, and Cochrane Library databases in January 2018 and included all randomized controlled trials comparing BT with usual care after HFS. We performed a pairwise meta-analysis using fixed- and random-effects models.


Results
Eight randomized controlled trials including a total of 752 participants were retrieved. The BT group showed significantly improved overall physical functioning after HFS compared with the usual care group (overall standardised mean difference [SMD]=0.390; 95% confidence interval [CI], 0.114-0.667; p=0.006). Both balance and gait improved (SMD=0.570; 95% CI, 0.149-0.992; p=0.008 and SMD=0.195; 95% CI, 0.043-0.347; p=0.012, respectively) in the BT group. Lower limb strength, performance task, activity of daily living, and health-related quality of life also improved significantly in the BT group.


Conclusion
Our meta-analysis revealed that BT after HFS improved overall physical functioning. Positive effects on balance, gait, lower limb strength, performance task, activity of daily living, and health-related quality of life were evident. Therefore, BT should be specifically included in postoperative rehabilitation programs and balance must be thoroughly checked in elderly patients with hip fractures.
