Figure 8

Estimated motoneuronal activity in the lumbosacral enlargement. The figure shows the spinal maps of all patients (elderly and young related patients respectively on the top and the bottom of the figure), those referring to the ensemble average across young and elderly healthy subjects (on the left of the panel), and their related CoAs (black lines). All spinal maps refer to the fastest walking speed. The white vertical lines and the gray bars overlapped to each spinal map indicate mean and standard errors of the onset of the contralateral heel strike. On the bottom, mean and standard deviation (one side error bar) of the ρ 2D related to the similarity between unaffected and affected side of post-stroke patients and healthy subject values at all speeds are reported. The red lines reflect the intra-group degree of similarity, in term of ρ 2D , between spinal maps of the healthy control group. The significance of difference between sides (black line) is indicated as * p < 0.05.
