No results posted yet for this study

Summary

This is a controlled trial designed to determine short- and long-term effects of repeated tDCS on the P300 component of event-related evoked potentials in patients with chronic neuropathic pain due to Complex regional Pain Syndrome (CRPS) or diabetic neuropathy as compared with healthy subjects.

Conditions

  • Diabetic Neuropathies
  • Complex Regional Pain Syndrome Type II
  • Resistant Peripheral Neuropathic Pain
  • Chemotherapy Induced Pain Neuropathy

Interventions

DEVICE

TDCS/sham procedure on five consecutive days

The latency and amplitude of P300, subjective pain intensity, and pain thresholds for tactile and thermal stimuli will be determined at before and 15 min and 120 min after the 1st and 5th tDCS/sham procedure, To receive tDCS/sham treatment, two electrodes will be placed on the patient´s skull (for details see section Methods) and the patient will rest for 5 min. After that, the patient will receive 20 minutes of 2 mA tDCS/sham. Subjective pain intensity, and pain thresholds for tactile and thermal stimuli will be determined before-, 15 min after and 120 min after each tDCS/Sham procedure. At the 1st and 5th tDCS/Sham session, the latency and amplitude of P300 will be determined before-, 15 min after and 120 min after the tDCS/sham procedure.
