Past literature has shown that balance and strength are important in preventing falls, but few studies have focused on developing strength and power in a lateral plane. The purpose of this study was to determine if a lateral pedal recumbent training device can improve balance scores among older adults in 4 weeks.
A 2-group experimental-control multivariate design (43 women, 13 men; age, 77.4 ± 3 years; weight, 78.91 ± 0.2 kg; height, 167.13 ± 0.8 cm; body mass index, 28.7 ± 0.5 kg/m) was selected for the study. Participants (n = 56) were divided into 2 groups and were pretested and posttested on a computerized posturography plate to determine center of pressure scores with eyes opened with stable surface (EOSS), with eyes closed with stable surface (ECSS), with eyes open with perturbed surface (EOPS), and with eyes closed with perturbed surface (ECPS). The experimental group used the lateral trainer for 15 minutes, 3 times per week, for 4 consecutive weeks; the control group maintained a sedentary lifestyle. A mixed-effects repeated measures multiple analysis of variance was used to determine significance.
There were statistically significant differences over time for EOPS (p = 0.047) and ECPS (p = 0.047). Likewise, there were statistically significant differences for each univariate outcome with EOSS (p = 0.045), ECSS (p = 0.033), EOPS (p = 0.010), and ECPS (p = 0.026).
A recumbent lateral stability device can improve balance scores among older adults within 4 weeks of training.
既往文献表明，平衡和力量对于预防跌倒很重要，但很少有研究关注于横向平面的力量和功率的提升。本研究旨在确定在 4 周内，横向蹬踏式斜躺训练设备是否可以提高老年人的平衡评分。
选择了 2 组实验对照的多变量设计（43 名女性，13 名男性；年龄 77.4±3 岁；体重 78.91±0.2kg；身高 167.13±0.8cm；身体质量指数 28.7±0.5kg/m2）。参与者（n=56）被分为 2 组，在电脑平衡测试平台上进行测试，睁眼稳定表面下的中心压力评分（EOSS）、闭眼稳定表面下的中心压力评分（ECSS）、睁眼干扰表面下的中心压力评分（EOPS）和闭眼干扰表面下的中心压力评分（ECPS）。实验组使用横向训练器进行 15 分钟，每周 3 次，连续 4 周；对照组保持久坐的生活方式。采用混合效应重复测量方差分析来确定差异的统计学意义。
EOSS（p=0.047）和 ECPS（p=0.047）的时间差异有统计学意义。同样，EOSS（p=0.045）、ECSS（p=0.033）、EOPS（p=0.010）和 ECPS（p=0.026）的单变量结果也有统计学意义。
斜躺式横向稳定性训练设备可以在 4 周的训练内提高老年人的平衡评分。
