Outcome measures
Primary outcome
The main study parameter is the relative change in single pulse Motor Evoked Potential (MEP) of the Tibialis Anterior and Vastus Lateralis at the post measurements compared to the baseline measurement.
Secondary outcome
Secondary parameters are change in intermuscular coherence between the Vastus Lateralis and Biceps Femoris, intramuscular coherence of the Tibialis Anterior, change in propulsion of the paretic leg, change in basic gait parameters, change in H-reflex of the Soleus, change in reciprocal Ia inhibition of the soleus and change in D2 inhibition at the post measurements compared to baseline. Other parameters are the leg portion of the Fugl Meyer score, the 10 m walk test and the motricity index.
Background summary
N/A
Study objective
Dual-hemisphere transcranial Direct Current Stimulation (tDCS) will result in a larger increase of the corticomotor excitability than uni-hemispere tDCS in healthy subjects and chronic stroke survivors.
Study design
N/A
Intervention
tDCS will be applied over the leg motor cortex of the subjects in 3 sessions. In each of the three experimental sessions a different form of stimulation will be applied being uni-hemisphere anodal stimulation, dual-hemisphere stimulation or sham (placebo) stimulation. The tDCS will be applied for 10 minutes and different tests will be performed before (baseline) and after the stimulation (post) to assess the effects of the stimulation condition.
