背景和目的。本研究探讨了敏感性和特异性的计时起来和去测试（TUG）在单任务与双任务的条件下，识别老年人谁是容易跌倒。科目15名无福尔斯跌倒史的老年人（平均年龄=78岁，SD=6，范围=65-85）和III名在过去6个月内有2次或2次以上福尔斯跌倒史的老年人（平均年龄=86.2岁，SD=6，范围=76-95）参加了研究。方法.在3种条件下完成拖船所需的时间（拖船，拖船与a。测量减法任务[TUG（认知）]和端满一杯水时的TUG [TUG（手动）]）。进行多因素方差分析、判别函数分析和Logistic回归分析。结果TUG被认为是一种敏感性（敏感性=87%）和特异性（特异性=87%）的措施，用于识别老年人谁是容易福尔斯。对于这两组老年人，同时执行额外的任务增加了完成TUG所需的时间，在有福尔斯病史的老年人中效果最大。TUG评分有或没有额外的任务（认知或手动）是等同的识别跌倒者和nonfallers。结论和讨论。结果表明，TUG是一种敏感和具体的措施，用于识别社区居住的成年人谁是福尔斯的风险。在进行牵引时，增加辅助任务并不能提高预测福尔斯的能力。
Background and Purpose. This study examined the sensitivity and specificity of the Timed Up & Go Test (TUG) under single-task versus dual-task conditions for identifying elderly individuals who are prone to falling. Subjects. Fifteen elder adults with no history of falls (mean age=78 years, SD=6, range=65-85) and Iii older adults with a history of 2 or more falls in the previous 6 months (mean age=86.2 years, SD=6, range=76-95) participated. Methods. Time taken to complete the TUG under 3 conditions (TUG, TUG with a. subtraction task [TUG(cognitive)], and TUG while carrying a full cup of water [TUG(manual)]) was measured. A multivariate analysis of variance and discriminant function and logistic regression analyses were performed. Results. The TUG was found to be a sensitive (sensitivity=87%) and specific (specificity=87%) measure for identifying elderly individuals who are prone to falls. For both groups of older adults, simultaneous performance of an additional task increased the time taken to complete the TUG, with the greatest effect in the older adults with a history of falls. The TUG scores with or without an additional task (cognitive or manual) were equivalent with respect to identifying fallers and nonfallers. Conclusions and Discussion. The results suggest that the TUG is a sensitive and specific measure for identifying community-dwelling adults who are at risk for Falls. The ability to predict falls is not enhanced by adding a secondary task when performing the TUG.
