背景调查运动对体弱的，制度化的个人与痴呆症的影响已经阻碍了对身体表现的措施，当用于这一人群的可靠性的关注。在第1天的上午和下午，由评分员1和在第2天的上午和下午，一周后，由评分员1和评分员2测量了33名患有阿尔茨海默病的机构化受试者的身体表现。计算组内相关系数（ICC），以检查“坐到站”、“25英尺步行”和“6分钟内步行距离”以及步行速度超过25英尺和6分钟的组间和组内可靠性。进行方差分析以确定每个测试的方差分量。“6分钟内步行距离”的ICC范围为。80到。99例，77%的方差由受试者间差异解释。“行走25英尺的时间”的ICC范围为0.57至0.97，25%的方差由受试者间差异解释。相比之下，“从坐到站”测量产生的ICC范围为-0.07至0.85，只有7%的方差是由该受损人群的受试者间差异解释的。结论。我们的研究结果支持这样的论点，即一些身体表现的措施，可以用来测试个人在后期阶段的阿尔茨海默氏病给予适当的修改。尽管患有阿尔茨海默病的受试者可能难以遵循命令和/或需要身体辅助，但如果在较长时间（6分钟步行）而不是较短时间（25英尺步行）内进行测量，这并不妨碍对身体表现进行可靠的评估。
Background. Investigation of the effects of exercise on frail, institutionalized individuals with dementia has been impeded by concerns about the reliability of physical performance measures when used in this population.Methods. The physical performance of 33 institutionalized subjects with Alzheimer's disease was measured during both the morning and afternoon of day 1 by rater 1 and during both the morning and afternoon of day 2, one week later, by rater 1 and rater 2. Intraclass correlation coefficients (ICCs) were calculated to examine the inter-and intrarater reliability of “sit to stand,” “25-foot walk,” and “the distance walked in 6 minutes” and walking speed over 25 feet and for 6 minutes. An analysis of variance was performed to determine the components of variance for each test.Results. ICCs for “distance walked in 6 minutes” ranged from. 80 to. 99 with 77% of the variance explained by inter-subject differences. The ICCs for “time to walk 25 feet” ranged from .57 to .97 with 25% of the variance explained by inter-subject differences. In contrast, the “sit to stand” measure produced ICCs ranging from –.07 to .85 with only 7% of the variance explained by inter-subject differences in this impaired population.Conclusion. Our results support the contention that some physical performance measures can be used to testindividuals in the later stages of Alzheimer's disease given appropriate modification. Although subjects with Alzheimer's disease may have difficulty following commands and/or require physical assistance, this does not prohibit the reliable assessment of physical performance if measurements are made over longer (6-minute walk) rather than shorter periods(25-foot walk).
