Figure 1From: Assessment of validity of a high-yield surface electromyogram decompositionSurface EMG recording and decomposition. A: 5-pin sEMG sensor array. B: 4 channels of sEMG recorded from the first dorsal interosseous muscle. C: Decomposed firing spikes and action potential templates of respective MUs. The STA estimated action potentials are also shown for comparison. The force trajectory is overlaid on top of the firing spikes.Back to article page
