确定不同的初始双足站立宽度 (ISW) 对单足平衡时间 (UBT) 临床测量的影响。观察性横断面研究。学术理疗门诊设施。 31 名患有已知会影响活动能力的神经肌肉和/或肌肉骨骼疾病的临床受试者，以及 30 名年龄相仿的健康受试者。记录人口统计和临床信息。 UBT 在三种不同条件下通过改变双足踝间距离来确定：1) ISW 为 0.3 身高； 2）0.05体高的ISW； 3) ISW 为 0 体高。最后一项是由受试者在保持单足平衡的同时将手放在水平表面上以保持稳定来完成的。受试者响应有节奏的命令抬起对侧脚（或在 0 身高条件下举起手），以最大限度地减少三种 ISW 条件下 UBT 重量转移速率的变化。平均 UBT 随着 ISW 的减少而增加，并且将每个 ISW 与下一个较小的 ISW 进行比较时差异显着。健康受试者在每个 ISW 中表现出比临床受试者更高的 UBT，但这些组间差异的程度在 ISW 条件下相似。在 0.3 身高 ISW 中 UBT > 10 秒是临床受试者和健康受试者之间的最佳区分因素。由于 UBT 随 ISW 的不同而变化，因此 ISW 的标准化对于受试者内部和受试者之间 UBT 的准确比较是必要的。健康受试者与临床受试者的最佳区别在于，在 0.3 身高 ISW 条件下 UBT > 10 秒。
To determine the effect of varying initial bipedal stance width (ISW) on the clinical measurement of unipedal balance time (UBT). Observational, cross sectional study. Academic physiatric outpatient facility. Thirty-one clinic subjects with neuromuscular and/or musculoskeletal conditions known to influence mobility, and 30 similarly-aged healthy subjects. Demographic and clinical information were recorded. UBT was determined under three distinct conditions by varying bipedal inter-malleolar distance: 1) ISW of 0.3 body height; 2) ISW of 0.05 body height; and 3) ISW of 0 body height. The last was accomplished by subjects assuming unipedal balance while using the hands on a horizontal surface for stabilization. Subjects lifted the contralateral foot (or hands in the case of 0 body height condition) in response to a cadenced command to minimize variation in rate of weight transfer UBT under each of the three ISW conditions. Mean UBT increased with decreasing ISW, and the differences were significant when comparing each ISW with the next smaller. Healthy subjects demonstrated greater UBT than clinic subjects at each ISW, but the magnitude of these group differences were similar across ISW condition. A UBT > 10 seconds in the 0.3 body height ISW was the best discriminator between clinic and healthy subjects. Because UBT varies with ISW, standardization of ISW is necessary for accurate within subject, and between subject, comparisons in UBT. Healthy subjects were best differentiated from clinic subjects by UBT > 10 sec in the 0.3 body height ISW condition.
