Figure 4From: Cortical activation change induced by neuromuscular electrical stimulation during hand movements: a functional NIRS study The different of time course of hemodynamic responses for oxy-hemoglobin (HbO) in the channels on the hand somatotopic area of the somatosensory motor cortex (SM1) between pre-neuromuscular electrical stimulation (NMES) motor phase and post-NMES motor phase (subject: a 28-year-old male; sham subject: a 28-year-old male).
