From Spinal Central Pattern Generators to Cortical Network: Integrated BCI for Walking Rehabilitation
Figure 4
PCPG performance as a function of the walking speed. (a) Superimposition of the real foot elevation angle (red) and the PCPG output (blue) by means of 7 oscillators. (b) The difference between SI values obtained with and without the interpolation is not significant. In this case, error bars are standard errors (modified from Duvinage et al. [46]).
