目的：研究二次任务对日常生活中平衡和步态动作的影响。我们的假设是，那些在熟悉的手工任务中同时进行功能性操作的人更容易分心，更虚弱，更容易摔倒。设计：对跌倒患者进行前瞻性随访的横断面设计。周边环境：瑞典乌姆(a)的避风住所。参与者：42名住院医师（30名女性，12名男性；平均年龄+/- SD = 79.7 +/- 6.1梨），有助行器或没有助行器，能够遵循简单的指示并能够拿玻璃杯。测量方法：计时向上走（TUG），即从扶手椅上站起来，走3米，转身，再坐下所需的时间。TUG被取消了，增加了一个手动任务（TUGmanual），即走路时端一杯水。采用Montgomery-(A) over circle sberg抑郁评定量表、Barthel指数、功能延伸、迷你精神状态检查和线平分测验评估虚弱程度。对受试者进行为期6个月的室内跌倒的前瞻性随访。结果：当TUGmanual和TUG的时间差（diffTUG）大于等于4.5秒时，被试被第二项任务分心。10名受试者在时间上的差异大于等于4.5秒。这些受试者更加虚弱，其中7人在随访期间摔倒在室内（优势比4.7,95%置信区间（CI） 1.5-14.2）。结论：TUGmanual和TUG之间的时间差似乎是一种有效的虚弱标志，也是识别老年人跌倒易感性的有用工具。
OBJECTIVE: To investigate the effect of a second task on balance and gait maneuvers used in everyday life. Our hy hypothesis was that those who there more distracted by a familiar manual task performed concurrently with functional maneuvers were more frail and more prone to falls.DESIGN: A cross-sectional design with prospective follow-up for falls.SETTING: Sheltered accommodation in Ume (a) over circle, Sweden.PARTICIPANTS: Forty-two residents (30 women, 12 men; mean age +/- SD = 79.7 +/- 6.1 pears), ambulant with or without a walking aid, able to follow simple instructions and able to carry a tumbler.MEASUREMENTS: Timed Up ec Go (TUG), i.e., the time taken to rise from an armchair, walk 3 meters, turn round, and sit down again. TUG was repeal-ed with an added manual task (TUGmanual), which was to carry a glass of water while walking. The Montgomery-(A) over circle sberg Depression Rating Scale, Barthel Index, Functional Reach, Mini-Mental State Examination, and Line Bisection test were used to assess for frailty. The subjects were followed-up prospectively regarding falls indoors for a period of 6-months. RESULTS: Subjects with a time difference (diffTUG) between TUGmanual and TUG of greater than or equal to 4.5 seconds were considered to be distracted by the second task. Ten subjects had a difference in time of greater than or equal to 4.5 seconds. These subjects were more frail, and seven of them fell indoors during the follow-up period (odds ratio 4.7, 95% Confidence Interval (CI) 1.5-14.2).CONCLUSION: The time difference between the TUGmanual and the TUG appears to be a valid marker of frailty and a useful tool for identifying older persons prone to falling.
