BACKGROUND AND PURPOSE
The purpose of this study was to determine the precision with which the postural stability data generated by the Chattecx Balance System could be converted to center of pressure displacement measurements.
SUBJECTS
Two men and one woman were selected to represent a broad range of body sizes (age = 23-33 years, height = 154-175 cm, weight = 45-80 kg).
METHODS
The Balance System load cells were placed on a force plate, and data were collected simultaneously from the Balance System and the force plate while the subjects performed standardized postural tasks. Linear regression analysis was used to characterize the relationship between the estimated center of pressure from the Balance System and the calculated center of pressure from the force plate.
RESULTS
Significant linear relationships between the center of pressure estimated from the Balance System and the center of pressure calculated from the force plate were determined (all R2 values = > .90).
CONCLUSION AND DISCUSSION
System data can be converted, and the methods recommended for use with the Balance System are described.
背景与目的
本研究的目的是确定Chattecx平衡系统生成的姿势稳定性数据可转换为压力中心位移测量值的精确程度。
受试者
选取两名男性和一名女性，以代表广泛的体型范围（年龄=23 - 33岁，身高=154 - 175厘米，体重=45 - 80千克）。
方法
将平衡系统称重传感器放置在测力板上，在受试者执行标准化姿势任务时，同时从平衡系统和测力板收集数据。使用线性回归分析来描述平衡系统估计的压力中心与测力板计算的压力中心之间的关系。
结果
确定了平衡系统估计的压力中心与测力板计算的压力中心之间存在显著的线性关系（所有R²值均>0.90）。
结论与讨论
系统数据可以进行转换，并描述了推荐用于平衡系统的方法。
