Trial Summary

What is the purpose of this trial?

The purpose of this study is to investigate the effectiveness of bodily illusions combined with transcranial direct current stimulation (tDCS) on neuropathic pain symptoms and sensory functions in participants with spinal cord injury (SCI) and neuropathic pain.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators.

What data supports the effectiveness of the treatment Multisensory Body-Representation Therapy for Spinal Cord Injury Pain?

Research shows that combining transcranial direct current stimulation (a gentle electrical brain stimulation) with visual illusions can significantly reduce neuropathic pain in spinal cord injury patients, with improvements lasting up to 12 weeks. This combined approach also enhances mood, sleep quality, and overall enjoyment of life. ^{1 2 3 4 5}

Is Multisensory Body-Representation Therapy, including tDCS and visual illusions, safe for humans?

Research indicates that transcranial direct current stimulation (tDCS) combined with visual illusions is generally safe for humans, with minimal side effects and good tolerability reported in studies involving patients with spinal cord injury and neuropathic pain. ^{2 3 4 6 7}

How is the treatment for spinal cord injury pain using tDCS and bodily illusions different from other treatments?

This treatment is unique because it combines transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, with visual illusions to reduce neuropathic pain in spinal cord injury patients. Unlike other treatments, this approach targets the brain's perception of pain and has shown significant long-term pain relief with minimal side effects. ^{1 2 3 4 8}

Transcranial direct current stimulation as a tool in the study of sensory-perceptual processing. Costa, TL., Lapenta, OM., Boggio, PS., et al.[2018]

In a study of 18 spinal cord injury patients with neuropathic pain, a 2-week treatment of transcranial direct current stimulation (tDCS) combined with visual illusion (VI) led to a significant 50% reduction in pain intensity as measured by a numerical rating scale.

The treatment also resulted in significant improvements in neurophysiological measures, including changes in contact heat-evoked potentials (CHEPs) and increased pain perception thresholds, suggesting these measures could serve as objective biomarkers for assessing treatment effects in neuropathic pain.

The effects of transcranial direct current stimulation with visual illusion in neuropathic pain due to spinal cord injury: an evoked potentials and quantitative thermal testing study. Kumru, H., Soler, D., Vidal, J., et al.[2012]

In a study involving 39 patients with neuropathic pain from spinal cord injury, the combination of transcranial direct current stimulation (tDCS) and visual illusion significantly reduced pain intensity more than either treatment alone.

The combined treatment not only improved overall pain perception immediately after treatment but also maintained significant benefits 12 weeks later, demonstrating its efficacy and good tolerability with minimal side effects.
