Modulating Neuropathic Pain With Transcranial Direct Current Stimulation

June 9, 2021 updated by: Susan McDowell
This study will examine whether a form of non-invasive brain stimulation can help reduce pain in people with persistent neuropathic pain.

Study Overview

Detailed Description

This study will look at the effects of a painless, non-invasive form of brain stimulation, called transcranial direct current stimulation, or tDCS. tDCS is thought to increase the brain's ability to change. Participants will be assigned to one of three groups by chance. Two groups will receive tDCS at a level expected to increase the brain's ability to change, while the other group will receive tDCS at a level not thought to affect the brain's ability to change.

Design Details

  • Primary Purpose: TREATMENT
  • Allocation: RANDOMIZED
  • Interventional Model: PARALLEL
  • Masking: SINGLE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: tDCS of DLPFC
Subjects will receive 20 minutes of active transcranial direct current stimulation at 2mA applied to the left dorsolateral prefrontal cortex (DLPFC). Subjects will undergo stimulation once a day for 10 consecutive weekdays.
EXPERIMENTAL: tDCS of M1
Subjects will receive 20 minutes of active transcranial direct current stimulation at 2mA applied to the left primary motor cortex (M1). Subjects will undergo stimulation once a day for 10 consecutive weekdays.
SHAM_COMPARATOR: Sham tDCS
Subjects will receive 20 minutes of sham transcranial direct current stimulation. Subjects will undergo stimulation once a day for 10 consecutive weekdays.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in McGill Pain Questionnaire from baseline 1 and 2 average
Time Frame: Baseline 1: 1 week before starting intervention, Baseline 2: immediately before starting intervention, Intervention mid-point: after 5 days intervention, Post-intervention: after 10 days intervention, Follow up: 1 month after completing intervention
This self-reported assessment measures intensity and quality of pain. Scores can range from 0 to 45. A decrease in score indicates an improvement in pain.
Baseline 1: 1 week before starting intervention, Baseline 2: immediately before starting intervention, Intervention mid-point: after 5 days intervention, Post-intervention: after 10 days intervention, Follow up: 1 month after completing intervention

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Short-Form 36 Health Survey from baseline 1 and 2 average
Time Frame: Baseline 1: 1 week before starting intervention, Baseline 2: immediately before starting intervention, Intervention mid-point: after 5 days intervention, Post-intervention: after 10 days intervention, Follow up: 1 month after completing intervention
This self-reported assessment provides information regarding an individual's perception of their health and quality of life. Scores range from 0 to 100. An increase in score indicates an improvement in perceived health and quality of life.
Baseline 1: 1 week before starting intervention, Baseline 2: immediately before starting intervention, Intervention mid-point: after 5 days intervention, Post-intervention: after 10 days intervention, Follow up: 1 month after completing intervention
