Summary

The present study aims to compare directly the efficacy of two noninvasive neurostimulation techniques : repetitive transcranial magnetic stimulation and transcranial direct electrical current of the motor cortex in patients with chronic lumbar radiculopathy on pain intensity.

Detailed description

The present study ims to compare directly the efficacy of two noninvasive neurostimulation techniques : repetitive transcranial magnetic stimulation (rTMS) and transcranial direct electrical current (tDCS) of the motor cortex in patients with chronic lumbar radiculopathy on average pain intensity. This will be a sham controlled crossover design : patients will be randomized to receive either active rTMS or tDCS during 3 consecutive days followed by the alternative treatment within 3 weeks apart, or sham rTMS or tDCS during 3 consecutive dats followed by the alternative treatment within 3 weeks apart. The investigator will be blind to the treatment. Assessments will be performed before each treatment, then 1 hour after the end of the third day session, then 2 days and 1 week after the stimulation. Assessments will include pain questionnaires, quality of life, anxiety and depression, catastrophizing and evaluation of treatment effect on experimental pain using Quantitative sensory testing.
