This study proposes a mecanum-built perturbation-based balance training device aimed at improving motor adaptive skills for fall prevention in individuals with neurological disorders or the elderly. Incorporating multidirectional fall simulations in line with modified constraint-induced movement therapy, the device’s efficacy was evaluated by measuring the distance traveled and peak acceleration under different static loads (20, 30, and 40 kg) and input accelerations (1, 2, and 3 m/s²). A pilot study with 10 subjects was conducted to assess device performance, utilizing repeated measures analysis of variance and Bonferroni’s post hoc analysis. Results indicated a load-dependent reduction in distance traveled, with an average mean difference of 0.74–1.23 cm between the 20 and 40 kg loads for trials of 9 and 18 cm, respectively. Despite varying loads, the device consistently achieved near-anticipated peak accelerations, suggesting its capability to induce effective perturbations. The study also observed a significant lateral movement preference, suggesting adjustments to pulse width modulation and time period may optimize lateral movement performance.

麦克纳姆摄动平衡训练装置的设计与性能分析

这项研究提出了一种麦克纳姆构建的基于扰动的平衡训练装置，旨在提高神经系统疾病患者或老年人预防跌倒的运动适应性技能。将多向跌倒模拟与改进的约束诱导运动疗法相结合，通过测量不同静态负载（20、30 和 40 公斤）和输入加速度（1、2 和 3）下的行进距离和峰值加速度来评估该设备的功效。米/秒²）。我们对 10 名受试者进行了一项试点研究，利用重复测量方差分析和 Bonferroni 事后分析来评估设备性能。结果表明，行驶距离随负载而减少，在 9 厘米和 18 厘米的试验中，20 公斤和 40 公斤负载之间的平均差异分别为 0.74-1.23 厘米。尽管负载变化，该设备始终达到接近预期的峰值加速度，这表明它有能力引起有效的扰动。该研究还观察到显着的横向运动偏好，表明调整脉宽调制和时间段可能会优化横向运动性能。
