In order to analyze the effect of working posture on the level of neck, back and shoulder muscular activity, a clinico-anamnestic, electromyographic and postural study of 34 dentistry was undertaken. Using surface electrodes, the level of muscular activity was recorded. The results showed that neck flexed working posture is prevalent: using stereomicroscope gave lower levels than with or without enlarging systems, such as glasses.
为了分析工作姿势对颈部、背部和肩部肌肉活动水平的影响，对34名牙科医生进行了临床问诊、肌电图和姿势研究。使用表面电极记录肌肉活动水平。结果表明，颈部弯曲的工作姿势很普遍：使用体视显微镜时的肌肉活动水平低于使用或不使用放大系统（如眼镜）时的水平。
