3D continuos hand motion reconstruction from dual EEG and EMG recordings

The precise reconstruction of continuous hand movements is a complex problem that remains unsolved to a large extent. In particular, this problem needs to be addressed to build reliable arm prosthesis for trans-humeral amputees. Current attempts using noninvasive techniques either had specifications that made them inapplicable to the real world or had low correlation values. In this study we use simultaneous EEG and EMG recordings showing the importance of combining both of them for reaching high accuracy in a real world applicable approach. We also analyse four different predictors to solve the problem. In this study with 16 subjects we obtained correlation values up to 0.875.
