Brain Stimulation and Chair Yoga for Knee Pain in Alzheimer's Patients

This trial is testing a combination of two treatments for chronic knee pain in people with Alzheimer's disease or related dementias: transcranial direct current stimulation (tDCS), which uses gentle electrical current on the scalp to help the brain process pain better, and online chair yoga, a seated yoga practice you can do from home. The study wants to see if combining these two approaches together—delivered safely in your own home—can reduce knee pain and improve mood and thinking abilities.

Many older adults with memory loss experience chronic knee pain, but treating it is difficult because pain medications (especially opioids) can be risky for this population. This trial exists to test whether non-drug treatments like this combination can safely and effectively reduce pain without the risks of medication.
