Table 1 Gait velocity under different stimulation conditions. Table 1 shows gait velocities in patient 1 and patient 2 on activation day and after 3 months. In patient 1 there was no significant change in maximum gait velocity over 10 m (one-sided paired T-test: T = 1.6, p = 0.13). In patient 2, however, maximum gait velocity had increased significantly immediately after activation, persisting after 3 months of FES, and on and off mode also differed significantly at each time point (one-sided paired T-test: T = − 8.9, p = 0.006)
