Some symptoms related to disequilibrium may not be detected by a clinical exam. Therefore, objective study is important in assessing balance. In this paper, methods to measure balance in computer posturography are compared. Center of pressure (COP) displacement, equilibrium score (ES) and postural stability index (PSI), the main measures of assessing balance are described and their merits and disadvantages are discussed. Clinicians should apply that measure which suits the specific strategies in a specific situation. Measuring devices such as Force plate, Balance Master and Equitest are also discussed. Although the Balance Master and Equitest devices are more costly compared to the force plate only, they are more useful for assessing balance relevant to daily life activities that might result in falls.
一些与平衡失调相关的症状可能无法通过临床检查检测出来。因此，客观研究对于评估平衡很重要。本文比较了计算机姿势描记术中测量平衡的方法。描述了评估平衡的主要指标——压力中心（COP）位移、平衡分数（ES）和姿势稳定性指数（PSI），并讨论了它们的优缺点。临床医生应根据具体情况选择适合特定策略的测量方法。还讨论了诸如测力板、平衡大师和Equitest等测量设备。虽然平衡大师和Equitest设备比仅测力板更昂贵，但它们对于评估与可能导致跌倒的日常生活活动相关的平衡更有用。
