A Criteria-Based BFR Progression, Safety Screening and Early Phases

The speaker presents his progression: passive, aerobic, non-weight-bearing, partial weight-bearing and weight-bearing BFR phases, each with its own entry criteria, training principles and exercises. He waits at least seven days after surgery, around two weeks with additional ligament reconstructions, and requires a closed wound, no fever or reactive swelling, and blood pressure below 140 mmHg. On safety, he stresses medical screening, objective limb occlusion pressure assessment and correct protocols. Key contraindications include active or previous deep vein thrombosis, blood disease, severe hypertension and multiple comorbidities. The evidence does not support the idea that BFR causes blood clots. Passive BFR serves as familiarization and to counter arthrogenic muscle inhibition: three times a week, three to five bouts of three to five minutes at 50 to 80% of occlusion pressure, combined early with muscle contractions or electrostimulation. The aerobic phase requires more than 110 degrees of knee flexion and pain at most 4 out of 10, and volume, such as one to two 10-minute sets on the bike, is the main driver.
