(1)长时间颈部前屈姿势下的 iEMG 变化能一 定程度的反映颈部疲劳状况,iEMG 的增大在一定 程度上反应肌肉疲劳程度;随着肌肉疲劳加重,后 期出现 iEMG 波动是肌肉发生重度疲劳的标志. (2)MPF 具有更好的非线性特征,本研究提出 用窗口化的 MPF 的导数积聚程度来表征肌肉疲劳 特征的新方法,用窗口化的 MPF 导数负数累积判 定肌肉疲劳,具有很好的评价效果. (3)在长时间颈部前屈过程中,胸锁乳突肌最 易疲劳,建议最长低头时间不超过 20 min,以降低 颈椎病发病的风险. 参 考 文 献 He J B. Analysis of the Correlation of Neck Pain with Cervical Curvature and Tendon Injury in Juveniles[Dissertation].
