摘要:: 基于随机共振的白噪声刺激已被证实可以提高人体的平衡能力，但目前缺乏多感官刺激对人体平衡能力的研究，因此本研究旨在探究不同强度足底振动刺激及触觉-前庭觉多感官联合刺激对健康成年人平衡能力的影响。实验采用自研足底微振动刺激鞋垫，将白噪声转换为电信号以驱动振动电机刺激足底触觉，并通过测力平台测量受试者95%足底压力中心（CoP）置信椭圆面积以评估平衡能力。试验分为两部分：（1）研究不同强度足底振动刺激（空白、强振动、阈值振动）的影响，结果显示阈值振动可使CoP包络面积降低201.500 mm2，但差异无统计学意义（P>0.05）。（2）研究多感官刺激效果，比较空白组（无刺激）、声音刺激（前庭觉）、振动刺激（足底触觉）及声音振动刺激这4种条件下的平衡参数。结果表明，声音刺激和振动刺激的单感官刺激均能显著提升平衡能力，相较于空白组CoP包络面积分别降低44.840 mm2和44.147 mm2；声音刺激和振动刺激的多感官联合刺激效果更优，CoP包络面积降低77.574 mm2，证明多感官协同可显著增强平衡改善效果。本研究证实足底阈值振动与前庭白噪声刺激均可有效改善平衡，且多感官联合刺激具有协同增强作用。

Abstract:: White noise stimulation based on stochastic resonance has been proven to improve human balance. However, research on the effects of multisensory stimulation on balance remains limited. Therefore, this study aims to investigate the impacts of plantar vibration stimuli at varying intensities and combined tactile-vestibular multisensory stimulation on balance in healthy adults. The experiment utilizes self-developed plantar micro-vibration stimulation insoles, which convert white noise into electrical signals to drive miniature vibration motors for tactile stimulation to the plantar surface. Balance is assessed by measuring the 95% confidence ellipse area of the center of pressure (CoP) using a force platform. The experiment is divided into two parts. (1) Examining the effects of plantar vibration stimulation at varying intensities (no vibration, strong vibration, and threshold vibration). The results show that threshold vibration reduces the CoP envelope area by 201.500 mm2, but the difference is not statistically significant (P>0.05). (2) Investigating the effects of multisensory stimulation by comparing balance parameters under 4 conditions: a control condition (no stimulation), auditory stimulation (vestibular), vibration stimulation (plantar tactile), and combined vibration-auditory stimulation. The results show that both auditory and vibration single-mode stimulation significantly improve balance, reducing the CoP envelope area by 44.840 mm2 and 44.147 mm2, respectively, compared with the control condition. Furthermore, combined vibration-auditory multisensory stimulation achieves even better results, with a 77.574 mm2 reduction in CoP envelope area, demonstrating that multisensory integration significantly enhances balance improvement. This study confirms that both plantar threshold vibration and vestibular white noise stimulation effectively improve balance, with multisensory stimulation providing synergistic benefits.
