Table 8 Pearson’s correlation between change in gait velocity at maximum and comfortable pace and change in SF-36 score and its sub-categories over the corresponding time period with the stimulation ON. All patients for whom the ANOVAs were calculated were included. Note that the findings were unaltered when the two patients with MS with complete data available were excluded. * = p < 0.05
