Vibration therapy has been widely used and published in alleviating muscle fatigue. However, reports on applying vibration therapy based on the holisitic theory of traditional Chinese medicine (TCM) remains limited. This study is to evaluate the immediate effect of vibration therapy on exercise-induced muscle fatigue.
For this retrospective parallel controlled study, all data were from a previously approved and completed clinical trial. Participants (n=40) in the clinical trial included local Greco-Roman wrestling and Judo athletes in south China. The participants were equally randomly divided into the intervention group (n=20) and control group (n=20). The intervention group received a seven-week vibration intervention-based TCM holistic theory combined with conventional therapy, such as stretching, massage, and flapping, while the control group only received the conventional therapy. Surface electromyography (sEMG) of the lumbar segment of erector spinae was measured for each participant pre- and postintervention, and the two-point discrimination thresholds of the data were differentiated and compared with panel data analysis.
For the control group, the pre- and postintervention sEMG measure showed no significant difference (=0.333), whereas significant difference (=0.004) was observed for the intervention group. Further, the pre- and postintervention two-point discrimination test also showed a significant difference (=0.016) for the intervention group.
The application of vibration therapy based on TCM holistic theory may have an immediate effect in reducing sport-induced muscle fatigue from intensive training. Future larger sample size and robust designed clinical trial is warranted to evaluate the long-term effect of the intervention.
振动疗法在缓解肌肉疲劳方面已得到广泛应用和报道。然而，基于中医整体理论应用振动疗法的报告仍然有限。本研究旨在评估振动疗法对运动引起的肌肉疲劳的即时效果。
对于这项回顾性平行对照研究，所有数据均来自先前批准并完成的临床试验。该临床试验的参与者（n = 40）包括中国南方当地的古典式摔跤和柔道运动员。参与者被随机平均分为干预组（n = 20）和对照组（n = 20）。干预组接受为期七周的基于中医整体理论的振动干预，并结合拉伸、按摩和拍打等传统疗法，而对照组仅接受传统疗法。在干预前后测量每位参与者竖脊肌腰段的表面肌电图（sEMG），并对数据的两点辨别阈值进行区分，并通过面板数据分析进行比较。
对照组干预前后的sEMG测量结果无显著差异（= 0.333），而干预组则观察到显著差异（= 0.004）。此外，干预组干预前后的两点辨别测试也显示出显著差异（= 0.016）。
基于中医整体理论的振动疗法应用可能对减轻高强度训练引起的运动性肌肉疲劳有即时效果。未来有必要进行更大样本量和设计更稳健的临床试验来评估该干预措施的长期效果。
