平衡康复计划越来越受欢迎，成功率也越来越高，这种成功是由技术的发展所推动的，技术的发展使得可用的工具能够提供客观，定量和即时的结果。Balance Master是这样一种市售仪器，由连接到微计算机的双力平台组成，该微计算机提供与稳定性的理论极限相关的重心（COG）的视觉反馈。可以在静态中心位置或稳定性极限周围的外围位置（外围摇摆区域）测量自发身体摇摆。目标之间的轨迹也可以在时间（过渡时间）和过渡的精度（路径误差）方面进行分析，这给出了COG动态运动的定量测量。本研究检查了在两个训练时间表（每天和每周）和两个年龄组（20-35岁和60-75岁）的重复训练中使用该仪器时发生的练习效果。每组完成一系列姿势练习，在训练前后以及训练后约3周和6周评估静态和动态姿势变量。在睁眼、闭眼和COG的视觉反馈下测量自发身体摇摆。在四次标准评估中，没有观察到这些变量的显著变化。外围摇摆区和路径错误显着降低每日和每周训练组从训练前到训练后，这些技能保留在两个保留测试，而减少过渡时间的趋势并不显着。（250字处删节）
There has been a growing popularity and success rate of balance rehabilitation programs, and this success is paralleled by the growth of technology, making available instruments that provide objective, quantitative, and immediate results. The Balance Master is such a commercially available instrument, consisting of a dual-force platform connected to a micro-computer that provides visual feedback of the centre of gravity (COG) in relation to the theoretical limits of stability. Spontaneous body sway can be measured in a static central position, or in peripheral positions around the limits of stability (peripheral sway area). The trajectory between targets can also be analyzed in terms of time (transition time) and accuracy (path error) of transition, which gives a quantitative measure of dynamic movement of the COG. This study examined the practice effect that occurs while using this instrument over repeated sessions for two schedules of training (daily and weekly) and over two age groups (20-35 years, and 60-75 years). Each group completed a series of postural exercises, with an assessment of static and dynamic postural variables before and after training, and at approximately 3 and 6 weeks post-training. Spontaneous body sway was measured with eyes open, eyes closed, and with visual feedback of the COG. No significant changes were observed in these variables as measured over the four standard assessment occasions. Peripheral sway area and path error decreased significantly for both the daily and weekly training groups from pre- to post-training, and these skills were retained over both retention tests, whereas the tendency toward decreasing transition time was not significant.(ABSTRACT TRUNCATED AT 250 WORDS)
