Title: Transcranial Direct Current Stimulation in Older Persons With Knee Pain: Randomized Pilot Study
Brief Summary: The purpose of this research is to study the effects of Transcranial Direct Current Stimulation (tDCS) on clinical pain, mobility disability, and pain sensitivity to gain a better understanding of the factors that cause pain and disability in people with knee osteoarthritis (OA). In particular, people from different ethnic and racial groups may experience OA pain differently which is why the focus will be on older Asian Americans and non-Hispanic whites. It is important to find a reason for such difference so that a better treatment can be found for all OA patients. In addition, the research study will examine if there is any ethnic differences in pain and mobility disability. The investigator hypothesize that Asian Americans will report greater pain and mobility disability than non-Hispanic whites, and that active tDCS will result in improvement in pain and disability compared to sham tDCS.
