Effect of Visual-Feedback Balance Training on Balance and Walking Ability after Stroke: A Meta-Analysis

Objective To systematically review the effect of visual-feedback balanced training on balance, walking and daily living after stroke. Methods Randomized controlled trials （RCTs） about balance training instrument for balance and walking ability of stroke were electronically searched in PubMed, Web of Science, EMBASE, the Cochrane library, China National Knowledge Infrastructure,Wanfang Data, VIP Database for Chinese Technical Periodicals from the date of establishment to April 2018. Using RevMan 5.3 software to analyze all the results that conform to the standard by meta. Results A total of 565 patients of 12 RCTs were included. The results of meta analysis showed that after treatment, the Berg balance scale scores of 12 articles of balancing instrument training group and conventional balance training group with effect of the amount of MD=6.49, 95%CI 5.63~7.35, Z=14.77,P<0.000 01, the two groups have significant difference. The “Up & Go test”of 6 articles of balancing instrument training group and conventional balance training group with effect of the amount of MD=-3.91,95%CI -4.68~-3.14,Z=9.97,P<0.000 01, the two groups have significant differerce. The modify Barthel scores of balancing instrument training group and conventional balance training group with effect of the amount of MD=5.58, 95%CI 2.31~8.84, Z=3.35,P=0.000 8, the two groups have significant difference. Conclusion Balanced training instrument exercises effectively enhance the balance function of stroke patients, improve their walking function and their daily living ability, and it is more obvious than traditional balance training. However, there are few high level clinical studies related to the training of balance instrument, so a large sample of clinical randomized controlled trials is needed to verify its effectiveness.
