Intensity Sensitive Modulation Effect of Theta Burst Form of Median Nerve Stimulation on the Monosynaptic Spinal Reflex

Figure 1

Different patterns of EcTBS lead to different effects on the H-reflex. Inhibition occurred, mainly at 30 min, after EcTBS600 at 90% threshold (a), while mild facilitation occurred after EcTBS600 at 110% threshold (b). In EcTBS1200, stimulation at 90% threshold inhibited the H/M ratio for more than 45 min (c), while EcTBS1200 at 80% threshold produced no after effect (d). The vertical bars are results of each subject.
