Simple nerve stretch could ease knee arthritis pain without drugs

This study tests whether adding a specific nerve-stretching exercise (femoral nerve mobilization) to standard physical therapy can reduce pain and improve function in people with knee osteoarthritis. Fifty patients aged 50 or older with mild to moderate knee arthritis will be randomly assigned to receive either standard therapy alone or standard therapy plus the nerve stretch. Researchers will measure pain, knee function, quality of life, and signs of central sensitization (a heightened pain response) over four weeks.
