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.

Conditions

Interventions

DEVICE

Active tDCS

This group will receive tDCS with a constant current of 2 mA intensity will be applied for 20 minutes once a day for five consecutive days using a pair of thick (0.3 cm) rectangular surface sponge electrodes (5 cm x 7 cm) saturated with 10 mL of saline solution. The anode electrode will be placed over M1 (C3 or C4 according to the 10-20 system for EEG electrode placement) of the hemisphere contralateral to the affected knee, and the cathode electrode will be placed over the supraorbital region (SO) ipsilateral to the affected knee (M1-SO montage).

DEVICE

Sham tDCS

This group will receive tDCS with a constant current of 2 mA intensity will be applied for 30 seconds once a day for five consecutive days using a pair of thick (0.3 cm) rectangular surface sponge electrodes (5 cm x 7 cm) saturated with 10 mL of saline solution. The anode electrode will be placed over M1 (C3 or C4 according to the 10-20 system for EEG electrode placement) of the hemisphere contralateral to the affected knee, and the cathode electrode will be placed over the supraorbital region (SO) ipsilateral to the affected knee (M1-SO montage).
