我们研究了14例偏瘫患者，以验证以下假设：当偏瘫患者使用手杖辅助站立平衡时，他们的姿势摆动减少，他们的压力中心（COP）的平均位置向前移动并向手杖一侧移动，并且这些参数在标准手杖和四足手杖之间没有差异。每个受试者站在一个奇石力平台上，每隔10秒站三次：一组不使用手杖，一组使用标准手杖，一组使用四脚手杖。配对t检验显示，当受试者使用标准手杖时，中外侧（ML）和前后位（AP）移动（姿势摇摆）均显著减少。当他们使用标准手杖时，COP的平均ML位置也显着向手杖一侧移动，但平均AP位置没有显着差异。当他们使用四足手杖时，行走距离和COP位置的差异都不显着，尽管它们与使用标准手杖时的测量值相似，但与标准手杖相比没有显着差异。两个结论似乎是有根据的。首先，标准手杖对轻度至中度偏瘫患者站立平衡的力-平台测量有显著影响——特别是减少ML和AP姿势摇摆的程度以及COP向手杖一侧的平均位置的移动。其次，就站立平衡的测量而言，四脚手杖似乎并没有比标准手杖更有优势。
We studied 14 patients to test the hypotheses that, when patients with hemiparesis use a cane to assist standing balance, their postural sway decreases and the average position of their center of pressure (COP) shifts forward and towards the cane side, and that there is no difference in either of these parameters between standard and four-footed canes. Each subject stood on a Kistler force platform for three ten-second intervals: one without a cane, one with a standard cane, and one with a four-footed cane. Matched-pairs t tests revealed a significant decrease in both the mediolateral (ML) and anteroposterior (AP) travel (postural sway) when the subjects used the standard cane. There was also a significant shift of the average ML position of the COP toward the cane side when they used a standard cane, but no significant difference in the average AP position. When they used the four-footed cane, neither the differences in travel nor the differences in COP position were significant, although they were similar in magnitude to those measured when they used the standard cane, compared with which there was no significant difference. Two conclusions appear warranted. First, a standard cane has a significant effect on force-platform measures of the standing balance of persons with hemiparesis of mild-to-moderate severity--specifically a reduction in the extent of ML and AP postural sway and a shift in the mean position of the COP toward the cane side. Second, as regards such measures of standing balance, a four-footed cane appears to offer no advantage over a standard one.
