为提高平衡能力评估的精确性,提出使用测力板和姿态模块所测量的多模态人体运动信息来计算平衡指标的评估方法。选取两组健康的青年与老年受试者进行数据采集,通过组内相关系数进行重测信度验证,然后对两组受试者的平衡指标进行均值方差分析,最后利用系统聚类方法观察测力板、姿态模块对平衡能力的评估性能。实验结果表明使用测力板与姿态模块能给出合理精确的评估,这也进一步说明测力板与姿态模块结合使用的必要性。
In order to improve the assessment of balance capacity .This paper proposes to use the multi-modal human body movement information measured by force plates and attitude module to calculate balance index , selects two groups of healthy young and elderly subjects for data collection .The test-retest reliability is verified through the ICC , then analyzing the balance index of the two groups by mean-variance analysis .Finally make use of the system clustering method to observe the evaluating performance of balance capacity given by force plates and attitude module .Experimental results show that the use of force plates and attitude module can give a reasonable and accurate assessment , which further illustrate the necessity of combining force plates with gesture module .
