This study aimed to investigate the effects of 6 wks of peroneal longus neuromuscular electrical stimulation on the balance control ability in young adults with chronic ankle instability.
This study is a double-blind randomized controlled trial. Six weeks of neuromuscular electrical stimulation and placebo intervention were conducted in the neuromuscular electrical stimulation and control groups for 20 mins, three times a week, respectively. Thirty-eight participants successfully completed the whole intervention and single-leg standing tests. The kinetics data of the center of pressure trajectory during static single-leg stance were measured using a Kistler force platform. Two-way repeated measures analysis of variance was used to analyze the electrical stimulation effects.
Significant interactions were detected in Cumberland Ankle Instability Tool scores and all balance parameters including displacement X, displacement Y, 95% confidence ellipse area, root-mean-square, and center of pressure mean displacement velocity ( P < 0.05, 0.103 ≤ η 2 ≤ 0.201). Significant between-group differences were found in Cumberland Ankle Instability Tool scores ( P = 0.003, Cohen's d = 0.215), displacement X ( P = 0.045, Cohen's d = 0.107), root-mean-square ml ( P = 0.019, Cohen's d = 0.143), and 95% confidence ellipse area ( P = 0.031, Cohen's d = 0.123) after the 6-wk interventions.
Six weeks of neuromuscular electrical stimulation on the peroneus longus can improve static balance control ability in young adults with chronic ankle instability, especially the stability of ankle frontal plane.
本研究旨在探讨为期6周的腓骨长肌神经肌肉电刺激对慢性踝关节不稳青年成人平衡控制能力的影响。
本研究为双盲随机对照试验。神经肌肉电刺激组和对照组分别进行为期6周的神经肌肉电刺激和安慰剂干预，每次20分钟，每周3次。38名参与者成功完成了整个干预和单腿站立测试。使用奇石乐测力平台测量静态单腿站立时压力中心轨迹的动力学数据。采用双向重复测量方差分析来分析电刺激效果。
在坎伯兰踝关节不稳工具评分以及所有平衡参数（包括位移X、位移Y、95%置信椭圆面积、均方根和压力中心平均位移速度）中检测到显著交互作用（P<0.05，0.103≤η2≤0.201）。6周干预后，坎伯兰踝关节不稳工具评分（P = 0.003，科恩d值 = 0.215）、位移X（P = 0.045，科恩d值 = 0.107）、均方根ml（P = 0.019，科恩d值 = 0.143）和95%置信椭圆面积（P = 0.031，科恩d值 = 0.123）存在显著的组间差异。
为期6周的腓骨长肌神经肌肉电刺激可改善慢性踝关节不稳青年成人的静态平衡控制能力，尤其是踝关节额状面的稳定性。
