Offline finger position reconstruction. Sample test set predictions shown for the five DOAs of the robotic hand for (A) an able-bodied and (B) an amputee subject. The shown segments of activity correspond to two repetitions of each of the movements included in the calibration phase, in the following order: thumb flexion/extension, thumb abduction/adduction, index flexion/extension, middle flexion/extension, ring/little flexion/extension, index pointer, cylindrical grip, lateral grip, and tripod grip. R2, coefficient of determination.
