Objectives
Narrative objectives1
The purpose of the present study is to assess effects of a combination of bimanual motor training and bi-hemispheric transcranial direct current stimulation over motor cortices on neural mechanisms responsibly for sensorimotor functions in musicians with focal hand dystonia. We also aim to determine predictors of inter-individual differences in effects of the training across the patients.
