OBJECTIVE
To investigate the effects of multiple-modality exercise with or without additional mind-motor training on mobility outcomes in older adults with subjective cognitive complaints.
METHODS
This was a 24-week randomized controlled trial with a 28-week no-contact follow-up. Community-dwelling older adults underwent a thrice -weekly, Multiple-Modality exercise and Mind-Motor (M4) training or Multiple-Modality (M2) exercise with an active control intervention (balance, range of motion and breathing exercises). Study outcomes included differences between groups at 24weeks and after the no-contact follow-up (i.e., 52weeks) in usual and dual-task (DT, i.e., serial sevens [S7] and phonemic verbal fluency [VF] tasks) gait velocity, step length and cycle time variability, as well as DT cognitive accuracy.
RESULTS
127 participants (mean age 67.5 [7.3] years, 71% women) were randomized to either M2 (n=64) or M4 (n=63) groups. Participants were assessed at baseline, intervention endpoint (24weeks), and study endpoint (52weeks). At 24weeks, the M2 group demonstrated greater improvements in usual gait velocity, usual step length, and DT gait velocity (VF) compared to the M4 group, and no between- or within-group changes in DT accuracy were observed. At 52weeks, the M2 group retained the gains in gait velocity and step length, whereas the M4 group demonstrated trends for improvement (p=0.052) in DT cognitive accuracy (VF).
CONCLUSIONS
Our results suggest that additional mind-motor training was not effective to improve mobility outcomes. In fact, participants in the active control group experienced greater benefits as a result of the intervention.
目的
研究多模态运动训练与附加意念-运动训练对有主观认知主诉的老年人移动能力结局的影响。
方法
这是一项 24 周的随机对照试验，随后进行了 28 周的无接触随访。社区居住的老年人接受每周三次的多模态运动和意念-运动（M4）训练或多模态（M2）运动加积极对照干预（平衡、活动范围和呼吸练习）。研究结果包括在 24 周和无接触随访（即 52 周）时，常规和双重任务（DT，即连续 7 个数字[S7]和语音流畅性[VF]任务）步态速度、步长和周期时间变异性以及 DT 认知准确性的组间差异。
结果
127 名参与者（平均年龄 67.5[7.3]岁，71%为女性）被随机分为 M2 组（n=64）或 M4 组（n=63）。参与者在基线、干预终点（24 周）和研究终点（52 周）进行评估。在 24 周时，与 M4 组相比，M2 组在常规步态速度、常规步长和 DT 步态速度（VF）方面的改善更为显著，且未观察到 DT 准确性的组间或组内变化。在 52 周时，M2 组保留了步态速度和步长的提高，而 M4 组在 DT 认知准确性（VF）方面表现出改善的趋势（p=0.052）。
结论
我们的结果表明，附加意念-运动训练对改善移动能力结局无效。事实上，由于干预，积极对照组的参与者获得了更大的益处。
