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.

Assessment

Primary outcomes

- Motor-evoked potential elicited by a single-pulse transcranial magnetic stimulation (TMS)
- Short intracortical inhibition and facilitation derived from double-pulse TMS
- Structural and functional images of human brain using a magnetic resonance imaging (MRI)
- Musical Instrument Digital Interface (MIDI)
- Hand kinematics

Key secondary outcomes

- Personal traits evaluated by questionnaires
- Resting state network derived from fMRI
