Study Summary

Objectives The main objectives of this proposal are (1) to characterize motor learning abnormalities in patients with focal dystonia; (2) to show, using transcranial magnetic stimulation, that this abnormal motor learning went together with an impaired modulation by somatosensory inputs of short and long-interval paired-pulse inhibitions (sICI, lICI) and facilitations (sICF, ICF) of MEPs (ICIs and ICFs are thought to reflect activity of inhibitory and excitatory interneuron's in the primary motor cortex M1); (3) to show that abnormalities of long-term potentiation and long-term depression (LTP/LTD)-like mechanisms (tested using a paired associative stimulation (PAS) intervention), thought to play a crucial role in learning, are associated in dystonia with an abnormal modulation of ICIs and ICFs by somatosensory inputs. Study population 30 patients with a focal upper limb dystonia and 45 healthy volunteers will take part in the main study. 7 patients with a focal upper limb dystonia and 12 healthy volunteers will take part in the control study. Design In the main study: subjects will complete 5 different sessions: visit 1: clinical screening, 1 hour; visit PAS session, 3 hours; visit 3: a minimum of 7 days later, motor learning session, 3 hours; visit 4: follow-up 24 hours later, 1 hour and a half; visit 5, follow-up 48 hours later, 1 hour and a half. During the PAS session they will receive 15 minutes of repeated paired stimulations (transcranial magnetic stimulation -TMS- and peripheral stimulation) thought to produce LTP/LTD like phenomena in M1. During the motor learning sessions they will be asked to perform, as fast as possible, a metronome-paced (0.5 Hz) pinch of their index finger and thumb. They will have 3 blocks of motor practice during the motor learning session. Between each block of motor practice and before and after PAS, while they rest, subjects will receive paired-pulse transcranial magnetic stimulations (TMS) associated or not with peripheral
