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 4

Correlation of the symmetry index and hand function test. (a) The symmetry index of DTI-CST and peduncle was correlated with the ratio of hand function evaluation. Box and block test (B&B) results and DTI-CST symmetry index show a significant correlation (, ). (b) 9-hole peg test (9-hole) results and DTI-CST symmetry index showed a moderate correlation (, ). (c) Grip strength test (grip) results did not show a significant correlation with the DTI-CST symmetry index (, ). (d–f) The symmetry index of the peduncle did not show a significant correlation with hand function evaluation (B&B, for (d); 9-hole, for (e); and grip, for (f)).
