Abstract

BACKGROUND

To evaluate the effects of stationary cycling with electromyographic (EMG) biofeedback on neuromuscular control and function in individuals with knee osteoarthritis (OA).

METHODS

Fourteen knee OA patients were randomized into two groups: cycling with EMG biofeedback of the vastus medialis (EBF group) and cycling without biofeedback (Cycling group). Both groups underwent a six-week cycling program, 30 min per session, twice a week. Outcomes were measured at baseline and post-training. Knee pain and function were assessed using the Visual Analog Scale and the Knee Injury and Osteoarthritis Outcome Score (KOOS). Quadriceps strength and endurance were evaluated with an isokinetic machine, and muscle activation was recorded using a wireless EMG system. A two-way mixed-model analysis of variance (ANOVA) was used to assess the differences between sides and groups. For outcomes that were not normally distributed, the non-parametric Mann-Whitney U test was performed.

RESULTS

Both groups showed improvements in knee pain and function, with no significant differences between groups. Muscle strength remained largely unchanged, but the endurance was improved on the contralateral side (p = 0.038, η = 0.312). Larger muscle activations were observed at various time points during the 30-minute cycling test in the EBF group with significant increases in muscle recruitment in the vastus medialis (p = < 0.001 ~ 0.042, η = 0.482 ~ 0.996), rectus femoris (p = 0.003 ~ 0.040, η = 0.493 ~ 0.859) and vastus lateralis (p = 0.002 ~ 0.036, η = 0.534 ~ 0.875).

CONCLUSIONS

A six-week cycling program can alleviate pain and enhance knee function. EMG biofeedback of the vastus medialis significantly changed the neuromuscular control in the rectus femoris and vastus lateralis during cycling. Therefore, this study demonstrated that stationary cycling combined with electromyographic biofeedback training can enhance neuromuscular control of the quadriceps and potentially improve functional performance in patients with OA.

摘要

背景

评估采用肌电图（EMG）生物反馈的固定自行车运动对膝骨关节炎（OA）患者神经肌肉控制和功能的影响。

方法

14名膝OA患者被随机分为两组：接受股内侧肌EMG生物反馈的自行车运动组（EBF组）和无生物反馈的自行车运动组（自行车运动组）。两组均进行为期六周的自行车运动计划，每次运动30分钟，每周两次。在基线和训练后测量结果。使用视觉模拟量表和膝关节损伤与骨关节炎疗效评分（KOOS）评估膝关节疼痛和功能。用等速肌力测试仪评估股四头肌力量和耐力，并使用无线EMG系统记录肌肉激活情况。采用双向混合模型方差分析（ANOVA）评估组间和组内差异。对于非正态分布的结果，进行非参数曼-惠特尼U检验。

结果

两组膝关节疼痛和功能均有改善，组间无显著差异。肌肉力量基本保持不变，但对侧的耐力有所提高（p = 0.038，η = 0.312）。在EBF组30分钟的自行车运动测试中，在各个时间点观察到更大的肌肉激活，股内侧肌（p = < 0.001至0.042，η = 0.482至0.996）、股直肌（p = 0.003至0.040，η = 0.493至0.859）和股外侧肌（p = 0.002至0.036，η = 0.534至0.875）的肌肉募集显著增加。
