Clinical Trial Summary

The goal of this intervention study is to assess the effect of blood flow restricted (BFR) exercise integrated into the daily work tasks among hospital workers with or at increased risk of chronic knee pain. The main questions are: Can BFR exercise integrated into the daily work tasks reduce knee pain (primary outcome) and improve function and work ability among hospital workers with or at increased risk of chronic knee pain? Participants in the intervention group will for shorts bouts during their workdays integrate BFR into their daily work tasks involving walking, whereas the control group will continue as usual.
