To compare the Timed Up & Go (TUG) test between subjects with and without hemiparesis, considering the direction toward which they turned, and to determine the potential clinical variables that could explain possible observed differences between the groups and/or the turning directions.
Twenty-two hemiparetic and 22 matched control subjects performed the TUG twice, with each one turning in both directions. Measures of the strength and tonus of the quadriceps, gait speed, balance, and fear of falling were also collected.
Stroke subjects were slower in the TUG than the control group, independent of the direction toward which they turned (F = 45.87; p < .001). For both groups, similar performances were observed when turning toward the paretic and nonparetic/matched sides (F = 0.50; p = .48). The absolute differences between the two TUG trials were greater for the stroke subjects (p = .001) and were significantly correlated with gait speed, balance, and fear of falling (-0.69 < r < - 0.52; p < .013), with fear of falling being the only variable retained in the regression model (R2 = 0.44; p = .001). For the control subjects, no significant correlations were found.
The larger differences between the two TUG trials for the stroke subjects illustrated the impact of the turning direction on test performance. These differences were not related to hemiparesis, but to the fear of falling.
比较有偏瘫和无偏瘫受试者的计时起立行走（TUG）测试，考虑他们转身的方向，并确定可能解释两组之间和/或转身方向之间观察到的差异的潜在临床变量。
22名偏瘫受试者和22名匹配的对照受试者进行两次TUG测试，每个人都向两个方向转身。还收集了股四头肌力量和张力、步态速度、平衡和跌倒恐惧的测量数据。
中风受试者在TUG测试中的速度比对照组慢，与他们转身的方向无关（F = 45.87；p < .001）。对于两组，向偏瘫侧和非偏瘫/匹配侧转身时观察到相似的表现（F = 0.50；p = .48）。中风受试者两次TUG测试之间的绝对差异更大（p = .001），并且与步态速度、平衡和跌倒恐惧显著相关（-0.69 < r < - 0.52；p < .013），跌倒恐惧是回归模型中唯一保留的变量（R2 = 0.44；p = .001）。对于对照受试者，未发现显著相关性。
中风受试者两次TUG测试之间的较大差异说明了转身方向对测试表现的影响。这些差异与偏瘫无关，而是与跌倒恐惧有关。
