【 Abstract】 Objective In order to reduce the impact of prolonged neck recline on the physical and
splenius muscle. The neck musculus splenius fatigue occurs before trapezius and sternocleidomastoid muscle. At
the same time,the frequency domain indicators of electromyography signals can be used as a good evaluation
意义( P<0 05) ,相关性 MPF 指标优于 MF。 结论 长时间颈部后仰作业会引发斜方肌、胸锁乳头肌和颈
部夹肌疲劳,颈部夹肌先于斜方肌和胸锁乳突肌发生疲劳,同时肌电信号的频域指标可作为一个较好的
评价指标用于颈部肌肉疲劳评价。
