摘要
背景：拇外翻患者会出现足部固有肌肉的形态改变和功能减弱，尤其是拇外展肌：本研究旨在探讨在保守治疗的基础上增加神经肌肉电刺激对肌肉的体积和力量、畸形矫正、被动活动范围、疼痛和残疾的影响：28 名女性参与者（48 英尺）被随机分配到两组。两组的干预措施包括矫形器和锻炼（Ortho）。其中一组接受额外的神经肌肉电刺激，以激活内收肌。每组接受为期一个月的治疗，并在开始治疗前和治疗一个月后进行两次评估。数据分析采用了混合方差分析、协方差分析和非参数检验：结果：两组患者的肌肉量、外展力量、关节角度和被动背伸/跖屈都有显著变化（P P ≤ .05）。两组患者的疼痛均明显减轻（p p = .02）。两组的跖间角无明显差异（P = 0.86，部分等效应大小 = 0.001）。但是，正畸组的拇指外翻角度平均值（核磁共振成像）小于正畸 NMES 组（p = .007，部分等效效应大小 = 0.15）：结论：在主要体积和外翻矫正结果测量方面，两组显示出几乎相同的治疗效果。在这项研究中，与保守治疗相比，增加神经肌肉电刺激对治疗足外翻没有额外效果：RCT代码为IRCT20200915048725N1。
Additional effect of neuromuscular electrical stimulation in a conservative intervention on morphology and strength of abductor hallucis muscle and correction of hallux valgus deformity: a randomized controlled trial.
Background: In hallux valgus, morphological changes and functional weakness of intrinsic foot muscles occur, especially in the abductor hallucis muscle.
Objectives: This study aimed to investigate how a conservative treatment with the addition of neuromuscular electrical stimulation affects the volume and strength of the muscle, the correction of deformity, passive range of motion, pain, and disability.
Methods: Twenty-eight female participants (48 feet) were randomly assigned to two groups. The interventions included orthoses and exercise (Ortho) in both groups. One group received additional neuromuscular electrical stimulation of abductor hallucis muscle to activate it. Each group received the treatments for one month and was assessed two times, at baseline before starting and after one month of treatment. Mixed within-between ANOVA, analysis of covariance, and nonparametric tests were used for data analysis.
Results: The muscle volume, abduction strength, goniometric angle, and passive hallux dorsi/plantar flexion showed significant changes in both groups (p < .001). Subscales of the foot and ankle ability questionnaire, significantly changed (p ≤ .05). Pain decreased significantly in the two groups (p < .001 and p = .02). Intermetatarsal angle did not significantly differ between the two groups (p = .86, partial eta effect size = 0.001). But, the hallux valgus angle mean (on MRI) in the Ortho group was less than that of the orthoNMES group (p = .007, partial eta effect size = 0.15).
Conclusion: Both groups showed nearly identical treatment effects in the primary volume and hallux valgus correction outcome measures. In this study, adding neuromuscular electrical stimulation did not have an additional effect compared to conservative in the treatment of hallux valgus.
Trial registration number: The RCT Code is IRCT20200915048725N1.
期刊介绍：
The aim of Physiotherapy Theory and Practice is to provide an international, peer-reviewed forum for the publication, dissemination, and discussion of recent developments and current research in physiotherapy/physical therapy. The journal accepts original quantitative and qualitative research reports, theoretical papers, systematic literature reviews, clinical case reports, and technical clinical notes. Physiotherapy Theory and Practice; promotes post-basic education through reports, reviews, and updates on all aspects of physiotherapy and specialties relating to clinical physiotherapy.
