About

Epidural stimulation of the primary motor cortex (PMC) is indicated for the relief of neuropathic pain refractory to pharmacological treatment.

Full 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.

Enrollment: 14 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients suffering from neuropathic pain refractory to best pharmacological treatment, operated on for MCS with an internal pulse generator (IPG) capable of delivering both tonic and Burst DR(TM) stimulation waveforms.

Exclusion criteria

• Patients under 18 years old ; pregnancy
