50. Inter hemispheric comparison of PAS-induced cortical plasticity: A pilot study in healthy subjects

Dystonia is considered a "network" disease with an abnormal cortical plasticity induced by by paired-associated-stimulation. In this study, we applied the PAS-TMS paradigm in healthy subjects, with the aim to collect reliable data from both hemispheres in order to put the basis to future application in focal dystonia.We studied 7 healthy subjects (4 females; mean age 32.33±6.79years). We applied electrical stimulatrion of median nerve electrical and MEPs from both abductor pollicis brevis (APB) and first dorsal interosseous (FDI) muscles (2), following Stefan et al.
