40 male patients with anterior knee pain were randomized to a single session of low load resistance training with or without concomitant blood flow restriction intervention. Patients were assessed for change in pain during three functional test from pre-intervention to post-intervention. The functional tests including a shallow single leg squat test, a deep single leg squat test, and a step down test. Results demonstrated significant within-group reduction in pain during all three functional tests in the LLRT+BFR group, whereas reductions observed in the LLRT group were not statistically significant.
