Classification error for 4 hand motion classes for (a) 6 non-amputees and (b) two partial-hand amputees. In training paradigm 1, one classifier was trained with data from all wrist positions and tested with data from each wrist position separately. In training paradigm 2, thirteen classifiers were trained and tested with data from each wrist position separately and the results of all 13 classifiers were averaged. Error bars represent standard error
