The body maintains stability by integrating inputs from the central nervous system of vision, hearing, proprioception, and multiple senses. With the development of smart wearable devices, smart wearable devices can provide real-time center of pressure position-assisted balance control, which is beneficial to maintain physical balance.
Forty healthy college students (20 male, 20 female) participated in this study, and the posture balance actions of left-leg stance non-visual feedback, left-leg stance visual feedback, right-leg stance non-visual feedback, and right-leg stance visual feedback were performed. Visual feedback provided smart insoles matching Podoon APP on a tablet computer with the COP position displayed by a dot as real-time visual feedback.
The experimental results show that the displacement, velocity, radius, and area of the COP decreased significantly in the left-leg stance visual feedback/ right-leg stance visual feedback, the test compared the parameters in the left-leg stance non-visual feedback/right-leg stance nonvisual feedback (P < 0.05). Providing visual feedback through intelligent insoles can reduce the movement of the center of mass and maintain physical stability for healthy young people of different genders. In the one leg visual/non-visual in standing, the COP maximum anteroposterior displacement, COP anteroposterior velocity, COP radius, and COP area in women are significantly smaller than in men (P < 0.05). Women have better real-time balance control ability than men with smart insoles.
The simple intelligent wearable assisted devices can immediately increase the control ability in static stance of men and women, and women have better real-time balance control ability than men.
人体通过整合来自视觉、听觉、本体感觉和多种感觉的中枢神经系统输入来保持稳定性。随着智能可穿戴设备的发展,智能可穿戴设备可以提供实时的压力中心位置辅助平衡控制,这有利于保持身体平衡。
本研究纳入 40 名健康大学生(男 20 名,女 20 名),进行左腿站立无视觉反馈、左腿站立视觉反馈、右腿站立无视觉反馈和右腿站立视觉反馈的姿势平衡动作。视觉反馈通过平板电脑上与 Podoon APP 匹配的智能鞋垫提供,以点的形式显示 COP 位置作为实时视觉反馈。
实验结果表明,左腿站立视觉反馈/右腿站立视觉反馈时,COP 的位移、速度、半径和面积显著减小,与左腿站立无视觉反馈/右腿站立无视觉反馈的参数相比(P<0.05)。通过智能鞋垫提供视觉反馈可以减少质心的运动,维持不同性别健康年轻人的身体稳定性。在单腿视觉/非视觉站立中,女性的 COP 最大前后位移、COP 前后速度、COP 半径和 COP 面积明显小于男性(P<0.05)。与智能鞋垫相比,女性具有更好的实时平衡控制能力。
简单的智能可穿戴辅助设备可以立即提高男性和女性静态站立的控制能力,女性比男性具有更好的实时平衡控制能力。
