拇趾外翻是一种足畸形，主要表现为大脚趾和第一跖骨的偏斜。由于难以实施必要的干预措施，几乎没有证据表明训练拇展肌（AbdH）可以治疗HV。虽然神经肌肉电刺激（NMES）已被用于诱导自愿运动，目前还没有关于NMES的研究。我们的目的是验证NMES对AbdH肌肉功能的即时影响。NMES组（n = 15），电刺激20 min。假手术组（n = 15）设置刺激装置但不开启，记录静息状态和外展状态下的肌电图、HV角（HVA）和AbdH肌力。采用协方差分析，以基线作为协变量，研究组间差异。NMES显著改善了最大自主等长收缩（%MVIC）、运动时的HVA和肌肉力量（%MVIC：p= .00，HVA运动：p= .00，AbdH强度：p= .00）。静息时HVA无变化（p= 0.12）。在AbdH肌肉上应用NMES立即改善了其在运动期间的活动输出、肌肉力量和HVA。
Hallux valgus (HV) is a foot deformity with deviation of the greater toe and the first metatarsal. There is little evidence on training the abductor hallucis muscle (AbdH) to treat HV because of the difficulty in implementing the necessary interventions. Although neuromuscular electrical stimulation (NMES) has been used to induce voluntary exercise, there is currently no study on NMES for AbdH. We aimed to verify the immediate effect of NMES on the AbdH muscle function. For the NMES group (n = 15), electrical stimulation was applied for 20 min. In the sham group (n = 15), the stimulating device was set but not turned on. Electromyogram, HV angle (HVA) at rest and during abduction of the big toe, and strength of the AbdH were evaluated. Analysis of covariance was used to investigate differences between groups using the baseline as the covariate. NMES significantly improved the maximal voluntary isometric contractions (%MVIC), HVA at exercise, and muscle strength (%MVIC:p= .00, HVA exercise:p= .00, AbdH strength:p= .00). HVA at rest showed no change (p= .12). Application of NMES on the AbdH muscle immediately improved its activity output, muscle strength, and HVA during exercise.
