How Physical Therapists Can Help Manage Migraines and Vestibular Dysfunction
By Jordan Verbanaz at Axes Physical Therapy in Wentzville, MO
Blood Flow Restriction Therapy (BFRT) is gaining traction in both sports medicine and physical therapy as a cutting-edge, evidence-based approach to rehabilitation and performance. It allows patients to experience muscle growth and strength gains while lifting significantly lighter loads than traditional resistance training. This makes it ideal for individuals recovering from surgery, managing chronic pain, or seeking a safer alternative to high-load training.
At Axes Physical Therapy, we offer Blood Flow Restriction Therapy at all of our 21 Greater St. Louis and Southern Illinois locations, integrating it into personalized rehab programs that help patients recover faster and return to what they love doing.
What Is Blood Flow Restriction Therapy?
BFRT therapy involves placing a specialized pneumatic cuff or band around a limb to partially restrict venous blood flow while allowing arterial blood to enter. This creates a controlled state of hypoxia (low oxygen) in the muscle during exercise.
Why is this helpful? When muscles experience oxygen restriction under load, even with very light resistance (20–30% of your one-rep max), the body is tricked into believing it’s under high stress. This triggers physiological adaptations that usually only occur with heavy lifting:
- Increased muscle fiber recruitment (especially fast-twitch fibers)
- Elevated growth hormone and anabolic signaling
- Enhanced muscle protein synthesis
- Improved strength and endurance
In short, you get the gains of heavy lifting without the stress on joints, tendons, or healing tissues.
Who Benefits from BFRT Therapy?
BFR is ideal for a wide range of patients and conditions. It is especially useful when high mechanical loads are not safe, possible, or appropriate. At Axes PT, we may use BFRT therapy for:
1. Post-Surgical Rehabilitation
Patients recovering from surgeries such as:
- ACL Reconstruction
- Total Knee or Hip Replacement
- Rotator Cuff Repair
- Achilles Tendon Repair
… and many more, can safely regain strength with BFRT before progressing to full-load strength training.
2. Acute or Chronic Injury Recovery
BFR allows injured tissues to rest while the surrounding musculature continues to strengthen. This reduces deconditioning and improves recovery time.
3. Athletic Performance & Return to Sport
Athletes seeking to maintain or rebuild strength during deload phases or in-season recovery use BFRT to stay strong without overtraining.
4. Older Adults & Chronic Conditions
Individuals with arthritis, osteoporosis, or sarcopenia (age-related muscle loss) benefit from joint-friendly strength training without the need for heavy lifting.
5. Pain Management Patients
Research shows BFRT can help with neuromuscular pain and fibromyalgia, likely due to its positive impact on circulation, muscular tension, and hormone regulation.
Evidence-Based Benefits of BFRT
According to recent research published in the Journal of Orthopaedic & Sports Physical Therapy and Frontiers in Physiology, BFRT therapy provides the following benefits:
- 30–50% faster gains in muscle size and strength compared to light exercise without BFRT
- Accelerated recovery following orthopedic surgery
- Improved vascular health, including capillary growth and mitochondrial efficiency
- Positive hormonal response, including spikes in growth hormone and IGF-1
For those who cannot tolerate high mechanical loads due to pain or healing restrictions, BFRT is a safe and effective alternative to build strength.
Safety Considerations and Precautions
BFR is safe when used correctly under the supervision of a trained professional. At Axes, our licensed physical therapists use FDA-registered equipment and pressure-controlled cuffs to monitor limb occlusion safely.
Safety Guidelines Include:
- Customizing pressure levels based on individual limb size and blood pressure
- Monitoring for adverse symptoms (numbness, tingling, sharp pain)
- Educating patients on correct breathing and body mechanics
Each patient at Axes undergoes a full screening before BFRT is included in their treatment plan.
What to Expect During BFR Therapy at Axes
BFR sessions are integrated into your regular rehab plan. You may be asked to perform:
- Light resistance band or bodyweight exercises
- Seated leg extensions or arm curls
- Stationary cycling or treadmill walking
Sessions typically last 15 to 30 minutes and are closely supervised by your physical therapist. Most patients report muscle fatigue and a “burning” sensation, which is expected due to lactate buildup. Recovery is quick and most individuals experience improvements within a few sessions.
The Axes Advantage
At Axes Physical Therapy, we provide personalized rehabilitation plans, combining modern science with individualized care. BFRT is just one of the many specialized techniques we use to help our patients move better, feel better, and live pain-free.
Whether you’re recovering from surgery, managing pain, or trying to return to high-level performance, Blood Flow Restriction Therapy may be the missing link in your recovery plan. With 21 clinics across the region (and growing), scheduling an appointment is easy and no physician referral is needed.
