Objective: To compare the effects of Combined Training associated with Partial Blood Flow Restriction (CT-PBFR) on strength, pain, functionality, and quality of life in relation to the effects of Resistance Training associated with Partial Blood Flow Restriction (RT-PBFR) in patients with knee OA. Method: This is a randomized pilot study conducted in a rehabilitation center in Vitória, Brazil. Patients were randomly allocated into two groups with different interventions: group 1 (RT-PBFR) or group 2 (CT-PBFR) lasting 12 weeks. The prescription parameters were adjusted with the progression of sessions. CT-PBFR consisted of resistance exercise and aerobic exercise. Strength, pain, functionality, and quality of life were assessed at the beginning and end of the interventions. For PBFR, an appropriate sphygmomanometer was placed on the proximal region of the thighs and inflated to 60% of each patient's total occlusion pressure during exercise execution. Non-parametric tests were used to compare the two groups. Results: Twenty patients were included. There was a significant difference within and between groups in several parameters with similar effects. Notably, group 1 (RT-PBFR) was able to improve pain at time point 3 in a statistically significant way (p= 0.002) compared to group 2 (CT-PBFR). Conclusion: This study showed similar positive effects in both groups with RT-PBFR or CT-PBFR in improving strength, pain, functionality, and quality of life.
