Ipsilesional (i)M1 TMS-evoked motor cortical reactivity measured with EEG in stroke survivors with present (A) and absent (B) paretic leg motor evoked potentials (MEPs). A) Time-frequency plot of motor cortical beta coherence in participants with present paretic leg MEPs showed increased beta coherence immediately following iM1 TMS (top). TMS-evoked increases in beta coherence during iM1 TMS were observed for 88% (7/8) of participants with resting paretic leg MEPs present (bottom). B) Time-frequency plot of motor cortical beta coherence in participants with absent paretic leg MEPs did not show a TMS-evoked increase in beta coherence (top). The lack of beta coherence increase with iM1 TMS was observed in 83% (5/6) of participants with absent paretic leg MEPs (bottom). Stroke survivors with absent versus present MEPs who showed increased iM1 TMS-evoked beta coherence χ2(1, 14) = 7.02, p=.008).
