Oxygen Therapy Combined With Physical Therapy for Knee Arthritis

This trial examined whether a treatment called intermittent hypoxia-hyperoxia therapy (IHHT)—which involves breathing air with alternating low and high oxygen levels—worked better for knee arthritis when combined with conventional physical therapy. The trial compared this combined approach to physical therapy alone. Researchers measured improvements in pain, walking ability, balance, and inflammation markers.

Knee arthritis is a common and painful condition that significantly affects quality of life, especially in older adults and in lower-income countries where treatment options are limited. This trial explored whether this new oxygen-based treatment could offer a low-cost, non-medication approach to help people with knee arthritis feel better and move more easily.
