New Markers to Assess the Efficacity of Spinal Cord Stimulation for the Treatment of Chronic Lower Limb Pain (MOTIVE)

By combining the usual care of patients eligible for spinal cord stimulation (SME) with measurements of the HRV index (Heart Rate Variability), objective measurements of activity (number of steps, quality of sleep) and measurements of connectivity obtained by anatomical and functional magnetic resonance imaging (fMRI), the collection of preliminary data necessary for the analysis of markers correlated with the efficiency of stimulation will be possible. Ultimately, these markers could be used to optimize the perioperative management of these patients.
