Motor Organization in Schizencephaly: Outcomes of Transcranial Magnetic Stimulation and Diffusion Tensor Imaging of Motor Tract Projections Correlate with the Different Domains of Hand Function

Figure 2

Schematic depiction of the MEP pattern towards the more paretic hand and the correlation between each pattern and hand function test. (a) Schematic depiction of four MEP patterns directed toward the paralyzed hand; the upper two patterns correspond to “large lesions” without cMEP response [22]. The presence or absence of the described cMEP and iMEP was presented as a variable in (b–d). (b) Grip results according to the presence or absence of iMEP and cMEP response; in the absence of cMEP reaction, the relationship between the presence of the ipsilateral tract and the results of the grip strength test; significant correlation is shown (). (c) B&B results according to the presence or absence of iMEP and cMEP responses; no significant difference was observed. (d) 9-hole results according to the presence or absence of iMEP and cMEP responses; no significant difference was observed. Grip: grip strength test; B&B: box and block test; 9-hole: 9-hole peg test.
