The Masai barefoot technology is used as a treatment option within the field of physical therapy to treat leg, back or foot problems. No information, however, is available on how Masai barefoot technology changes gait or muscle activity.
Twelve healthy subjects underwent 3D gait analysis with simultaneously collecting surface electromyography data of the leg muscles when walking with regular shoes and with Masai barefoot technology-shoes. Before data collection, subjects were trained in Masai barefoot technology. A within-subjects study-design compared walking with regular shoes and Masai barefoot technology.
With Masai barefoot technology, subjects walked slower with smaller steps. Movement pattern at the ankle showed major changes with increased dorsiflexion angle at initial contact followed by a continuous plantarflexion movement until terminal stance phase. With changed kinematics, alterations in the activity of tibialis anterior and gastrocnemius muscles could be observed. Smaller differences in movement and muscle activity were seen at knee and hip level.
Masai barefoot technology has never been documented in detail concerning changes in movement pattern or muscle activity. This study showed that Masai barefoot technology changes movement patterns, especially at the ankle, and increases muscle activity. It may therefore be a useful training method for strengthening the muscle groups of the lower leg. Knee flexion and electromyographic characteristics around the knee joint are slightly increased and need to be considered in patients with knee problems. Our findings provide critical detailed information on changes compared to walking in regular shoes, but the clinical relevance of those changes remains to be determined.
马赛赤足技术在物理治疗领域被用作治疗腿部、背部或足部问题的一种选择。然而，关于马赛赤足技术如何改变步态或肌肉活动，尚无相关信息。
12名健康受试者在穿着普通鞋子和马赛赤足技术鞋行走时，接受了三维步态分析，并同时收集腿部肌肉的表面肌电图数据。在数据收集之前，受试者接受了马赛赤足技术的训练。采用受试者内研究设计，比较穿着普通鞋子和马赛赤足技术鞋行走的情况。
使用马赛赤足技术时，受试者行走速度较慢，步幅较小。踝关节的运动模式显示出主要变化，初始接触时背屈角度增加，随后是持续的跖屈运动，直至终末支撑期。随着运动学的改变，可以观察到胫前肌和腓肠肌活动的变化。在膝关节和髋关节水平，运动和肌肉活动的差异较小。
马赛赤足技术在运动模式或肌肉活动变化方面从未有过详细记录。这项研究表明，马赛赤足技术会改变运动模式，尤其是在踝关节处，并增加肌肉活动。因此，它可能是一种加强小腿肌肉群的有用训练方法。膝关节屈曲和膝关节周围的肌电图特征略有增加，膝关节有问题的患者需要考虑这一点。我们的研究结果提供了与穿着普通鞋子行走相比变化的关键详细信息，但这些变化的临床相关性仍有待确定。
