(BFR) Therapy

Blood Flow Restriction (BFR) Therapy is a clinical technique that uses controlled pressure cuffs to partially restrict blood flow to the muscles during low-load exercise. This method stimulates muscle adaptation and strength gains while minimizing stress on joints and connective tissues. 

Mechanism of Action: 

BFR therapy involves the application of controlled external pressure to the proximal limb (upper arm or thigh), which partially restricts arterial inflow and significantly restricts venous outflow. This creates a low-oxygen (hypoxic) environment within the muscle, leading to: 

  • Increased metabolic accumulation 

  • Accelerated recruitment of fast-twitch muscle fibers 

  • Elevated production of anabolic hormones (e.g., growth hormone, IGF-1) 

  • Enhanced muscle protein synthesis 

  • Reduction in muscle atrophy during periods of limited load-bearing activity 

Clinical Applications: 

BFR is used to support: 

  • Strength training during rehabilitation when high mechanical loads are contraindicated 

  • Prevention of muscle wasting after orthopedic surgery or injury 

  • Management of chronic tendinopathies and joint conditions 

  • Enhancement of muscular endurance and hypertrophy in populations with limited loading capacity 

  • Accelerated recovery following musculoskeletal injuries or immobilization 

Procedure: 

Patients perform low-load exercises (typically at 20–30% of one-repetition maximum) while wearing BFR cuffs inflated to a personalized pressure based on limb occlusion measurements. Treatment sessions are closely monitored to ensure safety and effectiveness. BFR can be applied to both upper and lower limbs and is integrated into active rehabilitation or performance programs. 

Scientific Basis:

Research has demonstrated that BFR training can achieve muscle hypertrophy and strength improvements comparable to traditional high-load resistance training. It is a safe and effective intervention when applied by trained professionals, offering a valuable option for individuals requiring strength and recovery gains without excessive joint or tendon stress. 

At KNOSIS, BFR Therapy is carefully integrated into individualized rehabilitation and movement programs, always tailored to each patient’s specific functional needs, goals, and clinical status.
