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.

我们的研究项目旨在研究上肢和背部肌肉是如何被激活的。对手臂肌肉的兴趣源于许多人在失去一只手臂，有时两只手臂都失去时所面临的挑战。截肢时，肌肉被绑在残肢的末端。它们仍然可以收缩，但没有产生任何有用的动作。然而，随着肌电(EMG)信号在收缩的起点，肌电假体可以被激活。截肢通常只留下短小的前臂或没有前臂，而上臂为数不多但庞大的肌肉成为最好的控制点。我们的研究包括开发方法，通过使用表面电极阵列和来自超声(US)信号的弹性成像图，可以从这些庞大的肌肉中识别出许多表面控制点。通过促进多功能假体的操作，我们的研究可以为改善许多上肢截肢者的个人和职业生活做出贡献。
