Abstract:A large number of amputee patients doesn't use their myoelectric prosthesis, mainly due to the limited functionality of the prosthesis.
The aim of this study was to investigate if it is possible to distinguish 8 different contractions by using multi-electrode sEMG.
We analysed sEMG signals of a grid of 40 and 30 electrodes from 10 healthy subjects and 1 amputee patient respectively during 8 different isometric movements of the wrist and fingers and classified them with a nearest neighbour classifier.
The results were very promising: over 99.5% of the movements were correctly classified and reducing the number of electrodes to 20 and 10 electrods only decreases the performance with 0.05 and 0.18%.
