腰椎间盘突出症患者静态平衡功能分析

摘要

目的：探讨腰椎间盘突出症(LDH)患者的静态平衡功能。方法2015年1~9月，选取本科LDH患者30例作为观察组，另选正常成人30名为对照组，采用平衡测试仪对两组进行平衡功能检测并比较。结果观察组在睁眼状态下重心摆动轨迹长度、轨迹面积、前-后平均运动速度均大于对照组(t>2.262, P<0.05)，两组左-右平均运动速度无显著性差异(t=1.946, P=0.057)。闭眼状态下观察组各指标均明显大于对照组(t>2.767, P<0.01)。观察组Romberg值均大于对照组(t>2.326, P<0.05)。结论腰部本体感觉功能障碍及腰背部疼痛影响LDH患者姿势控制能力，患者更加依赖视觉信息的输入维持身体平衡。%Objective To investigate the static postural balance of patients with lumbar disc herniation (LDH). Methods From January to September, 2015, thirty patients with LDH were as observation group, and thirty healthy adult people were as control group. Their bal-ance function were detected and compared. Results The sway length, sway area and anteroposterior sway velocity were higher in the obser-vation group than in the control group (t>2.262, P<0.05), but there was no significant difference in mediolateral sway velocity between two groups (t=1.946, P=0.057) in eye-open condition. All of the indexes were higher in eye-closed condition in the observation group than in the control group (t>2.767, P<0.01), as well as the Romberg values (t>2.326, P<0.05). Conclusion Impairment of the proprioception and lower back pain affected the postural control of patients with LDH, who relied more on vision input to maintain postural stability.
