The third Ninapro database includes 11 trans-radial amputated subjects and it is thoroughly described in the paper: Atzori et al., Electromyography data for non-invasive naturally-controlled robotic hand prostheses. Scientific Data, 2014.
Please, cite this paper for any work related to the Ninapro database.
Please, consider that several clinical parameters related to the amputation can significantly influence the capability to classify hand movements using sEMG, as described in Atzori et al., Journal of Rehabilitation research and Development, 2016.
