目的评价组间肌电反复性对不同肌肉组选择导出模块的影响。方法记录12名参与实验者在自选速度下行走时16块肌肉的肌电图。用组内相关系数评价每个步行周期的肌肉兴奋度和肌肉模块。依据肌肉兴奋度的反复性,区分出3种类型的肌肉组。结果可靠肌肉组显示出较高的组内相关系数(>0.4),而全身肌肉组和混合肌肉组显示出较低的组内相关系数(<0.4)。3种类型肌肉组比较,可靠肌肉组分析得出的模块具有最好的反复性,全身肌肉组和混合肌肉组的反复性较低。结论具有较高可靠性的肌肉兴奋性能够得出较一致的模块。得出一致模块的方法非常重要,尤其是在依靠肌肉兴奋性反馈而改变的运动模式中。

Various treatments for the management of facial aging have been performed among which noninvasive radio-frequency (RF;i.e., thermage) treatment and minimally invasive treatments are on the rise. The purpose of this study was to analyze trends of the treatment of facial aging in Korea and to investigate relationships between the use of noninvasive RF and minimally invasive treatments. A retrospective analysis conducted on data from 4021 patients showed that thermage treatment increased by 134.9% over 5 years. As a person ages, the rate of facial treatment with both the botulinum toxin (for the masseter and lines of the glabella, lateral canthus, and forehead) and the PDO thread lift increases. The use of the treatments, nasolabial fold filler and Silhouette Soft Thread, however, was not associated with aging. The patients receiving thermage treatment were less likely to undergo any of the other treatments including PDO thread lift, Silhouette Soft Thread, nasolabial fold filler, or any of the botulinum toxin treatments. Overall, the results showed that patients who had received noninvasive RF tended to receive less minimally invasive treatment.
