摘要:
      目的:研究直立海绵垫姿势描记方法在分析人体姿势稳定性、评价正常人和眩晕患者姿势平衡能力时的信度。方法:25例正常人和34例病情处于稳定期的眩晕患者在3d内重复进行2次海绵垫姿势描记。测试4种不同站立条件下的静态姿势,依次为T1:睁眼站立于坚硬平板;T2:闭眼站立于坚硬平板;T3:睁眼站立海绵垫上;T4:闭眼站立海绵垫上。每种站立条件下各站立30s。记录测试中发生倾倒的情况;对于未倾倒者,姿势描记仪记录人体直立时足底压力中心晃动的平均速度(SV),作为姿势稳定性的参数。结果:健康对照组在各测试条件下未发生倾倒,而眩晕组有10例受试者在至少一次海绵垫姿势描记中发生倾倒,这部分患者结果不纳入信度分析。①49例受试者3d内重测的SV具有高度相关性(T1-T4四种测试条件下的ICC为0.973、0.931、0.932、0.887);②健康对照组和眩晕组在第一次测试中的SV比较,T2(P=0.049)和T4(P<0.001)条件下差异有显著性意义;第二次测试中的SV比较,T4条件下差异极显著性意义(P=0.001);③比较眩晕组中两次测试中倾倒发生的例数,差异无显著性意义(P=0.787)。结论:在评价正常人和病情处于稳定期的眩晕患者的平衡功能时,直立海绵垫时姿势描记具有较好的信度,提示该方法可用于评价前庭康复治疗对眩晕患者平衡功能的影响。

Abstract:
      Objective:To investigate the reliability of foam posturography in evaluation of equilibrium function in normal subjects and patients with vertigo. Method: Twenty-five normal subjects and thirty-four patients with vertigo were taken the foam posturography repeatedly in 3 to 5d. All subjects stood with static posture under 4 sensory conditions, such as firm surface with eyes opened(T1), firm surface with eyes closed(T2), foam surface with eyes opened (T3) and foam surface with eyes closed (T4) for 30s respectively. The average sway velocity (SV) of center of pressure (COP) under feet of every standing condition was recorded as parameter. Result: All normal subjects did not fall in all tests. There were 10 patients with vertigo at least fell one times during two assessments, and SV of these subjects were not taken in the analysis of reliability. ① The interclass correlation coefficients (ICC) of all 49 subjects were 0.887—0.973 according to T1—T4 between two assessments. ②The SV between normal subjects and patients with vertigo were significant different in T2(P=0.049) and T4(P<0.001) in the first assessment and T4(P=0.001) in the second. ③In the patients with vertigo the number of falling between two assessments were not significant different(P=0.787). Conclusion: The foam posturography possess high reliability to evaluate the postural stability in normal subjects and patients with vertigo, which indicate the foam posturography can be used as a method to evaluate the effect of equilibrium function rehabilitation therapy on postural stability for patients with vertigo.
