Premotor and Posterior Parietal Cortex Activity is Increased for Slow, as well as Fast Walking Poststroke: An fNIRS Study

Figure 2

Average and standard error (N = 20) change in laterality index for HbO during each walking condition. Positive values indicate more activation along the ipsilesional hemisphere and negative values indicate more activation along the contralesional hemisphere. PFC = prefrontal cortex; PMC = premotor cortex; SMC = sensorimotor cortex; PPC = posterior parietal cortex.
