Motor cortex stimulation, neuropathic pain, Burst DR(TM) waveform
Brief summary
Epidural stimulation of the primary motor cortex (PMC) is indicated for the relief of neuropathic pain refractory to pharmacological treatment.
Detailed description
The main objective of this study is to compare the analgesic effect of two distinct waveforms (i.e. tonic versus Burst DR(TM)) delivered by an epidural stimulator of the (primary) motor cortex in patients suffering from neuropathic pain resistant to the best pharmacological treatment.
Interventions
OTHERRetrospective analysis of patients' choice
Retrospective analysis of patients' choice of tonic or Burst DR(TM) waves for their analgesic effect.
