dcterms.abstractBien que l’imagerie motrice positive ait été bien étudiée et est utilisée en réhabilitation, l’effet de l’imagerie motrice négative est beaucoup moins connu. Le but de cette recherche était de définir si l’intention et/ou l’imagerie motrice négative serait en mesure de réduire l’effet d’une stimulation magnétique transcrânienne (SMT) sur le cortex moteur. Vingt participants ont reçu trente stimulations de SMT dans trois situations différentes : En restant passif, en portant une attention particulière aux sensations dans leur main ou en tentant de réduire l’effet de la SMT. La moitié des participants ont utilisé une stratégie d’imagerie motrice, l’autre moitié leur intention. Dans les deux cas, l’amplitude dans la condition de modulation n’a pas été réduite de façon significative.fr
dcterms.abstractAlthough positive motor imagery has been widely studied and is used in rehabilitation, the effect of negative motor imagery on our motor system is less well understood. Our goal was to ascertain whether intention and/or negative visual imagery is effective in decreasing the twitch resulting from transcranial magnetic stimulation (TMS) over the primary motor cortex. Twenty participants received 30 TMS stimulations in three different conditions: remaining passive, paying particular attention to the sensations in their hand, and attempting to modulate the amplitude of the resulting movement. To do this, half the participants used an imagery strategy, whereas the other half used an intention strategy. In both cases, amplitude in the modulation condition was not significantly reduced.fr
