Influence of Kinesiophobia on the Excitability of Connections Parieto-frontal During a Pointing Movement in Humans

Objective(s) of the trial: Better understand the interaction between kinesiophobia and motor control. Main objective: To measure the influence of induced kinesiophobia on functional connectivity between the posterior parieto-occipital region and the primary motor cortex in healthy subjects during a pointing task. Secondary objectives: The secondary objectives will be 1) to verify the excitatory influence of pIPS stimulation on the excitability of M1 at rest and 2) to establish whether there is a correlation between functional connectivity and the level of kinesiophobia ( as measured by the Tampa Scale)
