Fig 4. Effects of multiple sessions of intermittent theta-burst stimulation (iTBS) on the motor-evoked potential (MEP) amplitude.

Fig 4

Before the multiple sessions of iTBS, the MEP amplitude had increased in the healthy control group and showed less facilitation in the spinal cord injury (SCI) groups (A). After multiple sessions of iTBS, the MEP amplitude increased in all real stimulation groups but was less facilitated in the sham stimulation group, and the effects of iTBS in the five groups significantly differed from each other (B). There was no significant difference between MEP amplitudes pre- and post-iTBS in the severe-SCI group at postoperative 4 weeks (PO 4W) (C). There was a significant difference between the MEP amplitude in the severe-SCI group + RiTBS and severe-SCI group + SiTBS at PO 6W (D). * p < 0.05, ** p < 0.01, *** p < 0.001, by post-hoc Fisher’s LSD test on the MEP size between each time point post-SCI compared to the baseline.
