动态平衡仪与Berg量表用于评定偏瘫患者平衡功能的相关性分析

Application of dynamic balance instrument and Berg balance scale in assessing balance function of hemiplegic patients and analysis of its' correlation

目的:探讨Pro-KinLine动态平衡仪及Berg量表(BBS)在偏瘫患者平衡功能障碍评定中的应用价值及相关性。方法:选取脑卒中患者50例为实验组,健康志愿者41例纳入对照组。由治疗师用BBS及Pro-KinLine动态平衡仪对受试者平衡功能进行评定,分析BBS和动态平衡仪所得结果的相关性。结果:两组受试者的平均轨迹误差(ATE)及各项稳定指数具有显著性意义(P<0.05)。偏瘫组BBS得分与ATE、各项稳定指数均呈负相关(-0.226—-0.617,P<0.05);同时ATE与各项稳定指数均呈正相关(0.392—0.813,P<0.05),其中ATE与圆周稳定指数呈高度正相关(r=0.813,P<0.01)。结论:Berg量表和动态平衡仪测试均可反映偏瘫患者平衡功能且具有相关性,其中动态平衡仪较Berg量表更全面、详细、客观地反映患者的平衡功能。

Objective： To explore the application of balance assessments with Pro-Kin dynamic equipment and Berg balance scale（BBS） in assessing balance function of hemiplegic patients and to analyse it＇s correlation. Method： Fifty hemiplegic stroke patients （the patient group） and forty-one healthy volunteers （the control group） were recruited. Balance function of each subject was measured using BBS and Pro-Kin dynamic equipment. Result： The average trace error （ATE） and the sets of stability index （SI） showed significant differences between the patient group and the control group （P〈O.05 ）.The data obtained through Pro-Kin dynamic equipment assess- ment showed that ATE and SI were strongly negative correlated with BBS result（-0.301-0.604,P〈0.05）. Be- sides, there was a strong positive correlation between ATE and SI（0.392-0.813,P〈0.05）. Conclusion＂ The dynamic balance equipment and BBS can both effectively reflect the balance function of the hemiplegic patients. But the result of dynamic balance equipment is more objective and detail.
