To use two different exercise programs over a 2-year period to reduce falls and their sequelae among residents of two long-term care facilities.
Randomized, controlled trial.
The study took place at two long-term care facilities with services ranging from independent living to skilled nursing.
One hundred and ten participants whose average age was 84 and who were capable of ambulating with or without assistive devices and could follow simple directions.
Participants were randomized to one of two exercise groups (resistance/endurance plus basic enhanced programming or tai chi plus basic enhanced programming) or to a control group (basic enhanced programming only). Exercise classes were held three times per week throughout the study.
Participants were evaluated for cognitive and physical functioning at baseline and 6, 12, and 24 months. Falls were determined from incident reports filed by the nursing staffs at the facilities.
Time to first fall, time to death, number of days hospitalized, and incidence of falls did not differ among the treatment and control groups (P>.05). Among all participants, those who fell had significantly lower baseline Folstein Mini-Mental State Examination and instrumental activities of daily living scores and experienced significantly greater declines in these measures over the 2-year program.
There were no significant differences in falls among the two exercise groups and the control group. Lack of treatment differences and low adherence rates suggest that residents of long-term care facilities may require individualized exercise interventions that can be adapted to their changing needs.
在两年时间内使用两种不同的锻炼方案,以减少两家长期护理机构居民的跌倒及其后遗症。
随机对照试验。
研究在两家提供从独立生活到专业护理等一系列服务的长期护理机构进行。
110名参与者,平均年龄84岁,能够在有或没有辅助设备的情况下行走,并且能够听从简单指示。
参与者被随机分配到两个锻炼组之一(阻力/耐力加基本强化训练方案或太极拳加基本强化训练方案)或对照组(仅基本强化训练方案)。在整个研究过程中,锻炼课程每周进行三次。
在基线以及6个月、12个月和24个月时对参与者的认知和身体功能进行评估。跌倒情况根据各机构护理人员提交的事件报告确定。
首次跌倒时间、死亡时间、住院天数以及跌倒发生率在治疗组和对照组之间没有差异(P>0.05)。在所有参与者中,跌倒者的基线Folstein简易精神状态检查和日常生活工具性活动得分显著较低,并且在两年的项目期间这些指标的下降幅度显著更大。
两个锻炼组和对照组在跌倒方面没有显著差异。缺乏治疗差异和低依从率表明,长期护理机构的居民可能需要个性化的锻炼干预措施,以适应他们不断变化的需求。
