The rate of knee osteoarthritis has increased over time and with this the muscle weakness of the lower limbs due to the pathology. One of the techniques discovered to improve quadriceps muscle strengthening was the BRF technique (low blood flow restriction) or we will call this work “with occlusion”, that with low load, effective strengthening can be performed to improve pain and functionality in the lower limbs , improving the functional capacity of patients with symptomatic knee OA. Objective: To evaluate the improvement in pain and the gain in muscle strength of quadriceps in patients with symptomatic knee OA using the blood flow restriction technique (BRF - with occlusion). Method: 15 patients with knee OA (s) were eligible according to the classification criteria of the American College of Rheumatology (ACR), who reported pain complaints for at least 6 months, aged between 50 and 80 years, with intensity pain ranging from 3 to 8 out of 10 measured using the Numerical Verbal Scale for knee pain (EVN); Knee Functional Something Index (Lequesne) ranging from 5 to 15, and Kellgren & Lawrence Index ≥ 2, and who presented cognition to answer the Mini Mental questionnaire. The patients were randomized and divided into 2 groups with 15 participants, being: Group 1 with 6 participants (G1): BRF + Resistance exercise + Joint protection (PA) and Energy conservation (EC); Group 2 with 9 participants (G2): Resistance exercise + PA and EC. The treatment was carried out 3 times a week, for 4 weeks. The intensity of the applied load was 20% of the patient's own 1RM, with a number of 75 repetitions divided into 4 sets (30/15/15/15) with a rest of 30 seconds between sets. 13 The exercise was performed on the leg press equipment. The group that did not perform the BRF technique “with occlusion” was prescribed the same exercise on leg press equipment with guidance on joint protection and energy conservation. Results: Regarding the primary outcomes of the study, there was a decrease in pain on the EVN scale, after 12 sessions in 4 weeks, both techniques, without occlusion and with occlusion, presented a decrease in pain, however, the technique with occlusion was considered more significant. In all outcomes after 12 sessions, muscle strength gain for both techniques was not effective.
