Brain regions with significant intergroup differences in static image activity indictors between the stroke patients and the normal controls: (A) sALFF, (B) sfALFF, (C) sReHo, (D) sDC. The statistical threshold was set to p < 0.05 corrected with the Gaussian random field approach (the voxel level was p < 0.01). Data are mean ± SD. The color bar indicates the t-values. Ppre, stroke patients’ results at the first time point; Ppost, stroke patients’ results at the second time point; HC, healthy control; sALFF, static amplitude of low-frequency fluctuation; sfALFF, static fractional ALFF; sReHo, static regional homogeneity; sDC, static degree centrality.
