作者采用频谱肌电图表面电极法对健康成年男女腰背肌耐力进行了比较研究。 方法 受试者为45名健康成年志愿者,男22名,女23名,年龄20～30岁,均无腰背痛史及其他病理性发现。受试者接受腰背肌等长收缩测验,先仰卧休息20min,随后取俯卧位,下半身用三条带于臀、膝、踝处固定在床上,髂前上棘位于床边缘,上半身用滑动椅支撑。将两个表面银电极置于L_1平面
The author of the spectrum EMG surface electrode method for healthy adult men and women back muscle endurance were compared. Methods Subjects were 45 healthy adult volunteers, 22 males and 23 females, aged 20 to 30 years old, no history of low back pain and other pathological findings. The subject received a back muscle isometric contraction test, first supine rest 20min, then take the prone position, the lower body with three strips in the hip, knee, ankle fixed in bed, anterior superior iliac spine at the bed edge, the upper body with a sliding chair support . Place the two surface silver electrodes in the L_1 plane
