Transcranial Direct Current Stimulation Enhances Motor Skill Learning but Not Generalization in Chronic Stroke.

ABSTRACT:

Background

Motor training alone or combined with transcranial direct current stimulation (tDCS) positioned over the motor cortex (M1) improves motor function in chronic stroke. Currently, understanding of how tDCS influences the process of motor skill learning after stroke is lacking.

Objective

To assess the effects of tDCS on the stages of motor skill learning and on generalization to untrained motor function.

Methods

In this randomized, sham-controlled, blinded study of 56 mildly impaired chronic stroke patients, tDCS (anode over the ipsilesional M1 and cathode on the contralesional forehead) was applied during 5 days of training on an unfamiliar, challenging fine motor skill task (sequential visual isometric pinch force task). We assessed online and offline learnin
