Abbreviations: MAS: modified Ashworth scale
a Change values were calculated by subtracting the pre-training data (baseline) from the post-training data divided by the pre-training data and expressed as %
*, p<0.05 for intra-group difference
#, p<0.05 compared with control group
╪, p<0.05 compared with NMES-MG
