New study tests simple running tweaks to beat Runner's knee
NCT ID NCT07535866
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at two remote running programs for people with runner's knee (patellofemoral pain). One group was asked to increase their step rate and run less, another just ran less, and a third group kept running as usual. The goal was to see if these changes could reduce knee pain and improve function. The study involved 52 runners and followed them for up to 6 months.
