Could breathing different air ease knee pain? new study tests the idea

This study tested whether adding a special breathing therapy (intermittent hypoxia-hyperoxia) to standard physical therapy helps people with knee osteoarthritis. Sixty adults aged 45 and older with knee pain for at least 3 months took part. The breathing therapy involved short cycles of low and high oxygen levels before each physical therapy session, three times a week for four weeks. Researchers measured pain, function, balance, and inflammation to see if the combination worked better than physical therapy alone.
