Note: df = degree of freedom; after training, ARAT score between the MP + PP group and the PP group was compared; * P < 0.05, ** P < 0.01; posttraining-pretraining = the difference between posttraining and pretraining; contralateral-SMC AM = the number of activated voxels in contralateral SMC when ME using affected hand; contralateral-SMC AI = the number of activated voxels in contralateral SMC when MI using affected hand; contralateral-SMC UM = the number of activated voxels in contralateral SMC when ME using unaffected hand; contralateral-SMC UI = the number of activated voxels in contralateral SMC when MI using unaffected hand.
