In response to a question, where can I sign up for a clinical trial
The answer is: go to www.clinicaltrials.gov,
to find out. For example, if you search on “Transcranial
Direct Current Stimulation”, you get 16
results. However, no current trial involves
treatment for pain. There is one for treatment of depression,
but it is at the University
of New South Wales. UNSW is a fine institution, but
it’s a bit far to travel, for those of us in North America.
If you’re interested in something specifically in the Ann Arbor area,
you can try the UM site, Engage.
