Electromyography and elastography investigation of arm and trunk muscles

我们的研究计划是面向上肢和背部肌肉是如何激活的研究。 对手臂肌肉的兴趣来自于许多人失去一只手臂时所面临的挑战，有时是两只手臂。在截肢手术中，肌肉被绑在残肢末端。它们仍然可以收缩，但不会产生有用的运动。然而，利用收缩起点处的肌电图（EMG）信号，可以激活肌电假体。截肢通常只留下一个短的或没有前臂，上臂的几个但大量的肌肉成为最好的候选人作为控制部位。我们的研究包括在开发的方法，通过这些庞大的肌肉可以确定许多表面控制网站，通过使用表面电极阵列和弹性成像地图来自超声（US）信号。通过促进多功能假肢的操作，我们的研究可能有助于改善许多上肢截肢者的个人和职业生活。

Our research program is oriented toward the study of how upper limb and back muscles are activated. Interest in the arm's muscles derives from the challenge facing many persons when they lose one arm and sometimes both of them. During an amputation, muscles are tied around the end of the stump. They can still be contracted but no useful movement is produced. However, with the electromyographic (EMG) signal at the origin of the contraction, a myoelectric prosthesis can be activated. Amputation often leaves only a short or no forearm and the few but voluminous muscles of the upper arm become the best candidates as control sites. Our research consists at developing ways by which many surface control sites could be identified from these voluminous muscles by using surface electrodes arrays and elastography maps derived from ultrasound (US) signals. By facilitating the operation of multifunctional prostheses, our research could contribute to the improvement of the personal and professional life of many upper limb amputees.
