| Abstract Text | Myoeletric control of robotic prostheses is a widely used approach in medical research. In this work, different algorithms for analyzing the coherence between movement and EMG signals are used and compared. The goal was to find a method which is not only capable of finding coherences between the movement and its directly associated EMG, but also indirectly associated EMG. This aspect is important for later use in upper limb protheses control. An important finding of this work is that EMG signals and movements have a linear, negative or constant coherence, depending on muscle function. This method provides a fast way to compare signals offline. It turned out, that for finding an appropriate method, many factors have to be considered. A challenge for future work is to find a suitable method for analyzing data online. If we know how different movement signals are connected to each other and connected to EMG signals, it would be a big step forward to recognize and predict movements by means of few EMG sensors. |
