Summary

The purpose of this study is to evaluate the analgesic effect of transcutaneous spinal direct current stimulation (tsDCS) applied on spinal cord in patients with spinal cord injury who have chronic neuropathic pain.

Detailed description

Twenty patients with spinal cord injury and bilateral neuropathic pain received single sessions of both sham and anodal tsDCS (2 mA) over tenth thoracic vertebra for 20 min (reference electrodes on the head vertex). Treatment order was randomly assigned. A evaluator rated the pain using the visual analogue scale for pain, Patient Global Assessment and Present Pain Intensity.

Conditions

• Neuropathic Pain
• Spinal Cord Injury

Interventions

Type	Name	Description
DEVICE	tsDCS	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.
