Groups | Multiple comparison correction | Cluster size (mm3) | Peak MNI coordinates (x y z) | Peak statistical value |
NC, FOG−, FOG+ | GRF p < 0.05 | 1566 | –15 0 24 | F = 15.00 |
FOG+ vs. NC | GRF p < 0.05 | 1458 | –15 0 24 | T = 5.16 |
FOG− vs. NC | Uncorrected p < 0.05 | 351 | –15 21 9 | T = 3.44 |
FOG+ vs. FOG− | GRF p < 0.05 | 918 | –18 0 24 | T = 4.03 |
NC, normal controls; FOG+/FOG−, Parkinson’s disease with/without freezing of gait; MNI, montreal neurological institute; GRF, gaussian random field. The F-value indicates the statistical value among the three groups according to ANCOVA. The T-value indicates the statistical value of the between-group differences according to post hoc two-sample t-test.
