“…It is now established that high offline precision, does not necessarily translate into accurate functional control of a physical prosthesis. In this sense, several recent studies have shown the discrepancy between "on and offline" in performance metrics [7][8][9][10][11]. However, very few studies have published validation results of pattern recognition in terms, and even fewer in clinical settings, relating the variability of the signal and the performance of the classifiers with those parameters related to amputation (disability index, length remaining limb, amputation time, phantom limb sensation, etc.)…”
