NCT04578574

Brief Summary

The purpose of this study is to evaluate the effect of a combination of two procedures: (1) Bodily Illusion (BI) and (2) Transcranial direct electrical stimulation (tDCS) on neuropathic pain.

Outcome Measures

Primary Outcomes (2)

  • Change in Neuropathic Pain Severity

    Assessed by the use of the Neuropathic Pain Symptom Inventory (NPSI). The NPSI has a total score ranging from 0 to 100 with the higher score indicating greater pain.

    baseline, up to two weeks

  • Change in Performance of Body Part Processing

    Assessed by a customized computer task, where individual reaction times will be measured in response to mental rotation of body parts. Results will be reported in milliseconds.

    baseline, up to two weeks

Secondary Outcomes (1)

  • Change in Sensory Thresholds

    baseline, up to two weeks

Study Arms (2)

BI-TDCS Stimulation Group

EXPERIMENTAL

Participants in this group will receive the BI and TDCS interventions for 10 sessions over two weeks.

Other: Bodily Illusions (BI) ProcedureDevice: Transcranial direct electrical stimulation (tDCS)

BI-TDCS (Sham) Stimulation Group

SHAM COMPARATOR

Participants in this group will receive the BI and TDCS (Sham) interventions for 10 sessions over two weeks.

Other: Bodily Illusions (BI) ProcedureOther: Sham Transcranial Direct Electrical Stimulation (tDCS)

Interventions

Each sessions will consists of two types of illusions that are 15 min each, the rubber hand illusion (RHI) and the walking illusion (WI) that involve both arms and legs.

BI-TDCS (Sham) Stimulation GroupBI-TDCS Stimulation Group

Each sessions will consists of electrical current delivered from a battery-driven, constant current stimulator using saline-soaked surface sponge electrodes. One electrode will be placed on your scalp on the right side and the other electrode over the left eye on your forehead. A weak current will be applied for 30 min at the same time as the BI.

BI-TDCS Stimulation Group

Each session of the Sham tDCS will be applied for 30 min at the same time as the BI.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participants will be men or women, 18-70 years of age, with an incomplete cervical traumatic SCI.
  • Participants must have experienced neuropathic pain for a minimum of six months. They must have neuropathic pain in the moderate to severe category, which will be defined as a score of at least 4 on a Numeric Rating Scale (NRS); (range of 0 to 10).
  • Participants must be willing and able to sign informed consent

You may not qualify if:

  • Major psychiatric disease/disorder (self-reported)
  • A significant neurological trauma besides SCI
  • A recent (one-year) history of alcohol or drug abuse (selfreported)
  • Any other medical conditions in which transcranial DCS is relatively contraindicated, such as pregnancy, epilepsy and/or seizures
