Brief Summary:
Cortical excitability depends on inhibitory mechanisms efficiency among which long latency intracortical inhibition (LICI) can be studied by paired pulses transcranial magnetic stimulation (TMS). Some recent evidences suggest that LICI may be one of the mechanisms by which the motor comment is adapted to the ongoing motor task with LICI strength being dependent on task complexity. In writer cramp and musician cramp, two forms of dystonia, the cortical excitability is not correctly modulated in some complex gestures. the hypothesis is that this task dependent perturbation of excitability in writer cramp could be due to a lack of LICI efficiency.
