Abstract：
UNASSIGNED: To investigate the feasibility and efficacy of short-term functional power training and further examine whether the addition of cognitive training targeting sustained attention and inhibitory control would augment the effect on the outcomes.
UNASSIGNED: Randomized pilot study.
UNASSIGNED: Clinical research facility.
UNASSIGNED: Community-dwelling primary care patients (N=25) aged >65 years with mobility limitation within the VA Boston Healthcare System.
UNASSIGNED: Participants were randomly assigned to either functional power training (n=14) or functional power+cognitive training (n=11), offered 3 times a week for 6 weeks. Session durations were either 70 minutes (functional power+cognitive training) or 40 minutes (functional power training).
UNASSIGNED: We evaluated feasibility (dropouts, attendance), mobility performance (Short Physical Performance Battery [SPPB]), leg power [stair climb test]), dynamic balance [figure-of-8], and gait characteristics [gait speed, stance time, step width, swing time, step length, variabilities under single-task and dual-task conditions]). Nonparametric analyses were used to compare overall pre-post changes and between-group differences.
UNASSIGNED: Of the 39 veterans screened, 25 were randomized and enrolled. Twenty-one men with a mean age 76±7 years completed the study; 86% were white. Participants had a mean SPPB score of 8.3±1.6 out of 12. For those completing the study, overall attendance was 79%. Among all participants, clinically relevant and/or statistically significant median change in mobility performance (∆1 point), leg power (∆25.0W), dynamic balance (∆-1.1s), and gait characteristics (gait speed [∆0.08s, ∆0.09s], step length [∆1.9cm, ∆3.8cm], and stance time [∆-0.02s, ∆-0.05s] under single- and dual-task, respectively) were observed after 6 weeks of training. There were no statistically significant group differences in dropouts, attendance rate, or any of the outcomes based on cognitive training status.
UNASSIGNED: Short-term functional power training with or without a cognitive training led to clinically meaningful improvements in mobility performance, leg power, dynamic balance, and gait characteristics. These findings add to the body of evidence supporting the benefits of functional power training on clinically relevant outcomes. Additional cognitive training did not have an added effect on the study outcomes from our study. Further research is needed.

摘要：
■研究短期功能力量训练的可行性和有效性，并进一步研究以持续注意力和抑制控制为目标的认知训练是否会增加对结果的影响。
■随机试验研究。
■临床研究机构。
■社区居住的初级保健患者（N=25），年龄>65岁，在VA波士顿医疗保健系统中行动不便。
■参与者被随机分配到功能力量训练（n=14）或功能力量+认知训练（n=11）。每周提供3次，共6周。会话持续时间为70分钟(功能功率+认知训练)或40分钟(功能功率训练)。
■我们评估了可行性(辍学，出勤)，移动性性能（短物理性能电池[SPPB]），支腿功率[楼梯爬升测试]),动态平衡[图8]，和步态特征[步态速度，站立时间，步长,摆动时间,步长,单任务和双任务条件下的可变性])。非参数分析用于比较总体前后变化和组间差异。
■在筛选的39名退伍军人中，25人被随机分组并登记。21名平均年龄为76±7岁的男性完成了研究；86％是白人。参与者的SPPB平均得分为8.3±1.6（满分12分）。对于那些完成研究的人来说，总出勤率为79%。在所有参与者中，移动性表现的临床相关和/或统计学上显著的中位数变化(Δ1分)，支腿功率(Δ25.0W)，动平衡(Δ-1.1s)，和步态特征(步态速度[Δ0.08s，Δ0.09s]，步长[Δ1.9cm，Δ3.8cm],和站立时间[Δ-0.02s，取决于-0.05s]在单任务和双任务下，分别）在训练6周后观察。退学组差异无统计学意义,出勤率,或任何基于认知训练状态的结果。
■有或没有认知训练的短期功能力量训练导致了移动性表现的临床上有意义的改善，腿部力量,动平衡,和步态特征。这些发现增加了大量证据，支持功能力量训练对临床相关结果的益处。额外的认知训练对我们研究的研究结果没有额外的影响。需要进一步的研究。
