Blood Flow Restriction Therapy (BFRT) is achieved through the application of external pressure over the extremities via a cuff while performing rehabilitation. The applied pressure is sufficient to maintain arterial inflow while occluding venous outflow distal to the occlusion site. The goal of Blood Flow Restriction Therapy enables patients to make greater strength gains while lifting lighter loads, thereby reducing the overall stress placed on the limb. BFRT works by decreasing blood flow to working muscles with the aim of promoting hypertrophy, and preventing disuse atrophy of muscles. This treatment is typically used during exercise, but can also involve the use of compression devices alone.

What is Blood Flow Restriction Therapy and how does it work?
Personalized blood flow restriction rehabilitation, therapy and training
Personalized Tourniquet System (PTS) for Personalized Blood Flow Restriction Rehabilitation (PBFR), is manufactured by Delfi Medical Innovations, Inc, a world leader in tourniquet technology and safety. The PTS for PBFR device is specifically designed to safely regulate and control tourniquet pressure for PBFR applications and includes advanced personalization and safety features.
What to expect during BFRT
During BFR therapy, a patient works out with pressure tourniquet. The tourniquet partially restricts venous blood flow, but not arterial inflow to the extremity. Doing this produces a systemic response, comparative to heavy weight training. High repetitions of a particular exercise while wearing pressure tourniquets and using light weights allows the patient to receive the benefits of heavy lifting without the unnecessary and potentially dangerous stress to tissues that may be healing from a recent injury or surgery.

Increase growth hormone responses
Understanding how mechanical tension and metabolic stress impacts your muscles
When a muscle is undergoing stress, the concentration of anabolic hormone levels increase and the activation of myogenic stem cells results in protein metabolism. This can result in muscle hypertrophy. Release of hormones, hypoxia and cell swelling occurs when a muscle is under metabolic stress, and if that happens to you, you could be a good candidate for blood flow restriction therapy.
Release of Hormones
Exercise results in a significant increase in growth hormone. While growth hormone itself does not directly cause muscle hypertrophy, it helps with muscle recovery and potentially facilitates the muscle strengthening process. High intensity training regulates myostatin and provides an environment for muscle hypertrophy to occur.
Resistance training results in the compression of blood vessels within the muscles being trained, leading to a hypoxic environment, and an increase in anaerobic lactic metabolism and the production of lactate.
Cell swelling occurs when there is blood pooling and an accumulation of metabolites. This causes an anabolic reaction, results in muscle hypertrophy, and may actually cause mechanical tension. Ultimately, this will activate the myogenic stem cells and help with eventual recovery.
Who Can Benefit from BFR?
BFR therapy can be performed as part of a regular fitness routine as well as under the supervision of trained professionals in outpatient physical therapy clinics. BFR is often used to treat patients in the acute phase of rehabilitation following upper or lower extremity surgeries, including ACL reconstruction, meniscectomy, hip/knee replacement, rotator cuff and tendon repair. According to research, BFR can minimize loss of muscle mass, decrease bone healing time, and allow patients to improve both muscle size and strength. BFR is particularly suited for patients with osteoarthritis, rheumatoid arthritis, osteopenia or osteoporosis.
Uses of Blood Flow Restriction Therapy
- ACL reconstruction
- Achilles tendon repair
- Quad tendon repair
- Anyone who has a non-weight bearing injury or not able to rehab with any weights
- Anyone with a musculoskeletal injury (except for head and neck injuries)
- Anyone looking to improve muscular strength and endurance
