To investigate the biomechanical mechanisms underlying the pathogenesis and explore the effects of kinesiology taping (KT) on neuromuscular control in HV patients. The study population consisted of 16 young controls (YC group) and 15 patients with hallux valgus (HV group). All subjects underwent a natural velocity gait assessment. Additionally, 11 patients from the HV group received KT intervention over a period of one month, consisting of 15 sessions administered every other day. After the one-month intervention, these patients underwent a gait assessment and were included in the HV-KT group. The electromyography (EMG) and joint motion were evaluated using non-negative matrix factorization (NNMF) to compare the difference in muscle and kinematic synergy among the three groups. The center of plantar pressure (COP) and ground reaction force (GRF) were measured by the force platform. The number of synergies did not differ within the three groups, but the structure of muscle synergies and kinematic synergies differed in the HV group. The KT intervention (HV-KT group) altered the structure of synergies. The correlation between kinematic synergies and muscular synergies was lower in the HV group than in the YC group, whereas the correlation between the two increased after the KT intervention in the HV group. During gait, the HV group tended to activate more muscles around foot joints to maintain body stability. The visual analogue scale (VAS) scores, hallux valgus angle (HVA), and COP were significantly decreased after the intervention ( [Formula: see text]). HV patients exhibited altered kinematic and muscular synergies structures as well as muscle activation. Also, it weakened the balance and athletic ability of HV patients. KT intervention improved neuromuscular control to provide a better gait performance.
研究拇外翻（HV）患者发病机制背后的生物力学机制，并探讨肌内效贴布（KT）对其神经肌肉控制的影响。研究对象包括16名年轻对照者（YC组）和15名拇外翻患者（HV组）。所有受试者均接受自然速度步态评估。此外，HV组的11名患者接受了为期一个月的KT干预，包括每隔一天进行15次治疗。在为期一个月的干预后，这些患者接受了步态评估，并被纳入HV-KT组。使用非负矩阵分解（NNMF）评估肌电图（EMG）和关节运动，以比较三组之间肌肉和运动协同作用的差异。通过测力平台测量足底压力中心（COP）和地面反作用力（GRF）。三组之间协同作用的数量没有差异，但HV组的肌肉协同作用和运动协同作用结构不同。KT干预（HV-KT组）改变了协同作用的结构。HV组运动协同作用与肌肉协同作用之间的相关性低于YC组，而HV组在KT干预后两者之间的相关性增加。在步态过程中，HV组倾向于激活更多足部关节周围的肌肉以维持身体稳定性。干预后视觉模拟量表（VAS）评分、拇外翻角度（HVA）和COP均显著降低（[公式：见正文]）。HV患者表现出运动和肌肉协同结构以及肌肉激活的改变。此外它还削弱了HV患者的平衡和运动能力。KT干预改善了神经肌肉控制，以提供更好的步态表现。
