The Functional Standing Balance (FSB) Scale was designed to obtain measurements of standing balance and to identify the problems typically faced by people with stroke. The purpose of this study was to investigate the validity of measurements obtained with the FSB Scale for use in the acute and chronic phases of stroke by comparing the measurements obtained with the FSB Scale with those obtained for postural sway and lateral symmetry by use of a force platform.
Measurements were obtained for 26 people with recent strokes (ie, strokes within 3 weeks of data collection) and for 28 people with long-standing strokes (ie, strokes of 6 months' duration or older). The FSB Scale consists of 3 components: weight distribution, balance without movement, and balance with movement. Measurements of balance performance were compared with measurements of anteroposterior and lateral sway velocity obtained on a force platform. The weight distribution on 2 digital scales was compared with the lateral symmetry measured on the force platform.
The highest correlations were found between the FSB Scale balance measurements and the measurements of anteroposterior sway velocity obtained on the force platform with feet apart and eyes open. The correlations (r) were -.68 and -.67 for the group with recent strokes and -.74 and -.91 for the group with long-standing strokes. The correlations (r) between weight distribution measured on the digital scales and lateral symmetry measured on the force platform were.44 for the group with recent strokes and.52 for the group with long-standing strokes.
The subjects whose results on the FSB Scale were poor had higher sway velocities on the force platform than the subjects whose results on the FSB Scale were good. The results of this study suggest that the FSB Scale provides the same kind of information as that obtained for sway velocity and lateral symmetry as measured with the use of force platforms in both patients with recent strokes and patients with long-standing strokes.
功能性站立平衡（FSB）量表旨在获取站立平衡的测量数据，并识别中风患者通常面临的问题。本研究的目的是通过将FSB量表获得的测量结果与使用测力平台获得的姿势摇摆和侧向对称性测量结果进行比较，来调查FSB量表在中风急性期和慢性期测量的有效性。
对26例近期中风患者（即数据收集在中风后3周内）和28例长期中风患者（即中风持续时间为6个月或更长时间）进行了测量。FSB量表由三个部分组成：重量分布、静态平衡和动态平衡。将平衡性能的测量结果与在测力平台上获得的前后和侧向摇摆速度的测量结果进行比较。将两个数字秤上的重量分布与测力平台上测量的侧向对称性进行比较。
在双脚分开且睁眼的情况下，FSB量表平衡测量结果与测力平台上获得的前后摇摆速度测量结果之间的相关性最高。近期中风组的相关性（r）分别为-.68和-.67，长期中风组的相关性（r）分别为-.74和-.91。数字秤上测量的重量分布与测力平台上测量的侧向对称性之间的相关性，近期中风组为.44；长期中风组为(0.52)。
FSB量表结果较差的受试者在测力平台上的摇摆速度高于FSB量表结果较好的受试者。本研究结果表明，FSB量表提供的信息与使用测力平台测量的近期中风患者和长期中风患者的摇摆速度和侧向对称性所获得的信息相同。
