视觉代偿对脑卒中偏瘫患者平衡功能的影响

目的应用静态平衡仪检测视觉代偿对脑卒中偏瘫患者平衡功能的影响。方法对50例脑卒中偏瘫患者和40例正常对照组应用静态平衡仪分别在睁眼和闭眼状态下进行测试，对双下肢负荷比例偏差、重心标准偏差、超出目标数据比例、恢复到目标内的平均时间4个测试数据进行分析。结果脑卒中偏瘫患者在睁眼和闭眼状态下双下肢负荷比例偏差有显著性差异（P〈0．05），重心标准偏差、超出目标数据比例、恢复到目标内的平均时间有非常高度显著性差异（P〈0．001）；脑卒中偏维组睁眼与闭眼状态下的各检测指标与正常对照组均有非常高度显著性差异（P〈0．001）。结论静态平衡仪各检洲指标能客观、定量地反映视觉代偿对脑卒中偏瘫患者平衡功能的影响．

Effect of Visual Compensation on Balance Function of Post-stoke Hemiplegic Patients

ObjectiveTo test the effect of visual compensation on balance function of post-stoke hemiplegic patients with the static balancer.Methods50 hemiplegic patients and 40 healthy volunteers were tested with the static balancer. Four sets of data, including load difference of the lower limbs, standard deviation of the balance center, deviation percentage, and average rebalance time under modes with eyes open or closed were collected and analyzed.ResultsThere was a significant difference in load difference of the lower limbs of hemiplegic patients between eyes open and closed modes ( P<0.05), and standard deviation of the balance center, deviation percentage, and average rebalance time had more significant difference (P<0.001). There were also significant differences between data of hemiplegic patients and healthy volunteers ( P<0.001).ConclusionThe effect of visual compensation on balance function of post-stoke hemiplegic patients can tested by the static balancer objectively and quantificationally.
