The measurement of skeletal muscle with multi-parameters by sonography

Abstract

通过自行开发研制的超声运动与测量系 统,连续、同步获取了肱二头肌等长收缩活动时的B超图像力矩、肌电信号,并将超声扫描骨骼肌得到的有关骨骼肌结构的空间形态变化信息定义为“声肌图 (son-omyography,SMG)。通过采集到的信号研究并讨论了肌肉厚度变化率SMG和表面肌电信号、力矩之间的关系,并给出了经验公式,它对 了解骨骼肌功能、对骨骼肌建模以及对康复设备的研发等有重要的作用和意义。 The ultrasound signals,electromyography(EMG) signals and torque were synchronously and continuously acquired by a custom-developed ultrasonic measurement of motion and elasticity(UMME) system,and the dimensional architectural change of muscle continuously extracted from ultrasound images was defined as "sonomyography(SMG)".The relationship between the SMG of muscle thickness changes ratio,surface electromyography and torque from the biceps brachial under an isometric contraction were researched,and then the experiential expressions through experiments was given.It can help us to understand the skeletal muscle function,modeling the skeletal muscle model and develop the rehabilitation equipments.
