High Definition Transcranial Direct Current Stimulation Motor Cortex Versus Insula
The Effects of High Definition Transcranial Direct Current Stimulation Over Primary Motor Cortex Versus Insular Cortical Targets on Experimental Capsaicin Induced Hyperalgesia and Pain in Healthy Volunteers
Study Overview
Status
Conditions
Detailed Description
Repetitive transcranial magnetic stimulation and transcranial direct current stimulation are currently the two main methods of non-invasive brain stimulation under investigation. Stimulation of the primary motor cortex has been reported to relieve neuropathic, musculoskeletal, visceral pain as well as headaches and migraine. Other parameters of stimulation have shown encouraging results. For example, stimulation of the secondary somatosensory cortex was also reported to relieve chronic visceral pain. However, there are numerous unanswered questions regarding these techniques.
This research project is an attempt to answer some of these questions:
- Which pain conditions can be alleviated by non-invasive brain stimulation?
What are the best parameters for stimulation-
- method: transcranial direct current stimulation or repetitive transcranial magnetic stimulation transcranial or Alternating Current Stimulation
- High-Definition transcranial direct current stimulation or conventional transcranial direct current stimulation?
- which area to stimulate? Primary motor cortex, insula?
- Will other forms of treatment such as pharmacotherapy, peripheral nerve stimulation or multi-disciplinary pain management enhance the effectiveness of non-invasive brain stimulation

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain severity assessment using Numerical Rating Scale (NRS score from 0-100)
Time Frame: 30 min after capsaicin cream application and at the end of the HD tDCS session and one hour after study
|
we will put the capsaicin cream for 30 min at an area of 9 cm2 then we will assess the pain score throughout this time of application of the cream every 5 min
|
30 min after capsaicin cream application and at the end of the HD tDCS session and one hour after study
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
map area of sensitization caused by application of capsaicin cream
Time Frame: 30 min after the capsaicin cream application and at the end of HD tDCS sessionand one hour after study
|
The area of sensitization using calibrated Neurotip test using the spring mechanism which will exert a force of 40 gm so we will detect the change in sensation to the pin brick in the area of cream application
|
30 min after the capsaicin cream application and at the end of HD tDCS sessionand one hour after study
