目的 使用新开发的握力测量装置研究老年人握力与日常生活独立活动的关系。方法 本研究纳入了在国家老年病学和老年病学中心因记忆障碍门诊就诊的患者（142 名男性和 205 名女性，平均年龄 74.8 +/- 8.8 岁）。详细描述了它们在抓握性能时的力量，并计算了以下指标：最大力量（MS）、响应时间（RT）、达到MS的时间、到达转折点的时间（TP）、TP处的力量、从开始到TP的倾斜度、从TP到MS的时间、从TP到MS的倾斜度以及力量比（TP/MS）。采用Barthel指数（BI）、总分和各小类得分来评价日常生活独立能力。比较独立组和依赖组之间的 MS。使用针对年龄调整的部分皮尔逊系数和简易精神状态检查总分，按性别、侧别和年龄组分析指数与 BI 之间的相关性。结果独立组的 MS 显着较高。 MS 和 RT 与双手的 BI 总和某些亚类显着相关，TP/MS 在任一性别的右手中显着相关，并且 TP 的力量在女性的双手和男性的左手中显着相关。对于男性，双手到达 TP 的时间与右手从 TP 到达 MS 的时间尤其相关。指数的相关性因性别、手侧和年龄组而异，特别是70多岁的男性、70岁以下的女性和80多岁的女性。结论 MS 被证明是有用的，但一些新定义的指标，例如 RT、TP 强度以及 TP 前后直至达到 MS 的元素，也被认为是有用的。老年老年国际 2014； 14（补编 2）：77-86。
Aim To investigate the association of grip strength and activities of daily living independence in older adults, using a newly-developed grip strength measuring device. Methods Patients who visited the clinic for memory disorders at the National Center for Geriatrics and Gerontology (142 men and 205 women, mean age 74.8 +/- 8.8 years) were included in the present study. Their strength during gripping performance is described in detail, and following the indices were calculated: maximum strength (MS), response time (RT), time to MS, time to reach turning point (TP), strength at TP, inclination from start to TP, time from TP to reach MS, inclination from TP to MS and ratio of strength (TP/MS). Barthel Index (BI), total scores and scores of each subclass were used for evaluating activities of daily living independence. MS was compared between the independent and dependent groups. Correlations, using partial Pearson's coefficient adjusted for age, and Mini-Mental State Examination total score were analyzed between indices and BI by sex, side, and age groups. Results MS was significantly higher in the independent group. MS and RT were significantly related with BI total and certain subclasses in both hands, TP/MS was significantly related in the right hand of either sex, and strength at TP was significantly related in both hands in women and in the left hand in men. Time to reach TP was particularly correlated in both hands and time from TP to reach MS in the right hand, in men. The correlation of indices varied by sex, hand side and age group, especially in men aged in their 70s, and in women aged less than 70 years and women aged in their 80s. Conclusion MS was shown to be useful, but some of the newly defined indices, such as RT, strength at TP, and elements regarding before and after TP until reaching MS, were also suggested to be useful.
