Abstract：
BACKGROUND: Stair-climbing (SC) is an essential daily life skill, and stair-climbing exercise (SCE) serves as a valuable method for promoting physical activity in older adults. This study aimed to compare the impact of SCEs with heel contact (HC) and heel off (HO) during SC on functional mobility and trunk muscle (TM) activation amplitudes in community-dwelling older adults.
METHODS: In the pilot randomized controlled trial, participants were randomly allocated to either the HC group (n = 17; mean age 75.9 ± 6.3 years) or the HO group (n = 17; mean age 76.5 ± 4.6 years). The HC participants performed SCE with the heel of the ankle in contact with the ground, while the HO participants performed SCE with the heel of the ankle off the ground during SC. Both groups participated in progressive SCE for one hour per day, three days per week, over four consecutive weeks (totaling 12 sessions) at the community center. We measured timed stair-climbing (TSC), timed up and go (TUG), and electromyography (EMG) amplitudes of the TMs including rectus abdominis (RA), external oblique (EO), transverse abdominus and internal oblique abdominals (TrA-IO), and erector spinae (ES) during SC before and after the intervention.
RESULTS: Both groups showed a significant improvement in TSC and TUG after the intervention (P < .01, respectively), with no significant difference between the groups. There was no significant difference in the EMG activity of the TMs between the groups after the intervention. The amplitude of TMs significantly decreased after the intervention in both groups (P < .01, respectively).
CONCLUSIONS: Both SCE methods could improve balance and SC ability in older adults while reducing the recruitment of TMs during SC. Both SCE strategies are effective in improving functional mobility and promoting appropriate posture control during SC in older adults.

摘要：
背景：爬楼梯（SC）是一项必不可少的日常生活技能，爬楼梯运动（SCE）是促进老年人体育锻炼的一种有价值的方法。这项研究旨在比较SC期间SCE与脚跟接触（HC）和脚跟脱离（HO）对社区居住的老年人的功能活动性和躯干肌（TM）激活幅度的影响。
方法：在先导随机对照试验中，参与者被随机分为HC组(n=17;平均年龄75.9±6.3岁)或HO组(n=17;平均年龄76.5±4.6岁).HC参与者在脚踝脚跟与地面接触的情况下进行SCE，而HO参与者在SC期间脚踝脚跟离地进行SCE。两组每天都参加渐进式SCE一小时，每周三天,在社区中心连续四周(共12次)。我们测量了定时爬楼梯(TSC)，定时和去（TUG），和包括腹直肌（RA）在内的TM的肌电图（EMG）振幅，外斜（EO），腹横肌和腹内斜肌（TrA-IO），干预前后SC和竖脊肌（ES）。
结果：两组干预后TSC和TUG均有明显改善（分别为P<0.01），组间无显著差异。干预后各组间TMs的EMG活性无明显差异。干预后两组患者的TMs波幅均明显下降(P<0.01)。
结论：两种SCE方法都可以改善老年人的平衡和SC能力，同时减少SC期间TM的招募。两种SCE策略均可有效改善老年人SC期间的功能移动性并促进适当的姿势控制。
