La description
Inclusion Criteria:
- cervical or upper thoracic complete motor spinal cord injury, at least 6 months after SCI, 20<=age<90
- neuropathic pain (LANSS score >= 12), stable chronic pain for at least the three preceding months but not over 5 years
- score higher than or equal to 4 cm (0 cm = 'no pain' and 10 cm = 'worst possible pain') on the visual ana- logue scale (VAS) for pain perception at the baseline/start of the treatment
- refractoriness to drugs for pain relief - such as tricyclic antidepressants, antiepileptic drugs, and/or narcot- ics (pain resistant to at least two of these drugs supplied in ade- quate dosages for 6 months)
- informed consent
Exclusion Criteria:
- patients with any clinically significant or unstable medical or progressive neurologic disorder
- contraindication for electrial stimulation such as pacemaker implant
- Women of childbearing age or pregnancy
- significant cognitive deficit
- Syringomyelia
- neuropsychiatric comorbidity
- depressive disorder (as indicated by a score of 10 greater on the Beck Depression Inventory)
- history of substance abuse
- skin defect under the electrodes
- progressive neurological disease or other secondary conditions that could impact neuropathic pain

Intervention / Traitement |
|---|---|
|
Expérimental: tsDCS
In the tsDCS group, anodal tsDCS will be applied for 20 minutes.
|
Both groups use the same DC-Stimulator Plus (NeuroConn GmbH, Ilmenaus, Germany). In the tsDCS group, anode electrode is placed over tenth thoracic vertebra to target spinal cord with 2mA for 20 min, and the cathode (reference) electrode on the head vertex (in the Cz location according to the 10-20 EEG system) In sham tsDCS group, anode electrode is placed over tenth thoracic vertebra to target spinal cord with 2mA for 30s, and the cathode (reference) electrode on the head vertex (in the Cz location according to the 10-20 EEG system). The current was discontinued after 30 s while the power indicator remained on.

Comparateur placebo: sham
In sham tsDCS group, the current of anodal tsDCS will be discontinued after 30 s while the power indicator remained on for 20 minutes.

Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Numeric rating scale (NRS) for neuropathic pain
Délai: Baseline NRS (average NRS over the preceding 24h), Change from Baseline NRS at 0, 60 and 120 minutes after the start of the stimulation
|
On a scale of 0 to 10, with 0 being no pain at all and 10 being the worst pain imaginable
|
Baseline NRS (average NRS over the preceding 24h), Change from Baseline NRS at 0, 60 and 120 minutes after the start of the stimulation

Délai |
|---|---|---|
|
Patient Global Assessment (PGA)
Délai: Baseline PGA (average PGA over the preceding 24h), Change from Baseline PGA at 0, 60 and 120 minutes after the start of the stimulation
|
One of the most widely used patient reported outcomes (PROs) & PGA reflects the global impact of the disease from the patient's perspective
|
Baseline PGA (average PGA over the preceding 24h), Change from Baseline PGA at 0, 60 and 120 minutes after the start of the stimulation
|
|
Present Pain Intensity (PPI)
Délai: Baseline PPI (average PPI over the preceding 24h), Change from Baseline PPI at 0, 60 and 120 minutes after the start of the stimulation
|
Patient's subjective feeling of the intensity of pain right now 0: No pain
|
Baseline PPI (average PPI over the preceding 24h), Change from Baseline PPI at 0, 60 and 120 minutes after the start of the stimulation
