Blood Flow Restriction

Improving muscular strength is an important goal of physical therapy. Symptoms such as pain and stiffness are common road blocks to building strength when recovering from injury. 

Blood Flow Restriction (BFR) Training is a new training strategy that utilizes a specialized tourniquet system to limit blood flow to the muscle. Research has shown that this technique allows patients to achieve greater gains in muscle strength and hypertrophy while lifting significantly less weight, reducing the overall stress on the limb.

Proven to be completely safe in clinical practice, BFR can stimulate muscle growth in populations ranging from the elderly, to the elite athlete, to those with chronic musculoskeletal conditions and can reduce muscle atrophy in the post-surgical patient.

Compared to traditional low-load strengthening, Blood Flow Restriction Rehabilitation is more effective with less side effects, helping people to get back to doing what they love, faster.

Conditions that can be treated with BFR Training:

  • Total hip/knee replacement
  • Rotator cuff tear/tendonitis
  • ACL repair/reconstruction
  • Osteoarthritis
  • Achilles tendinopathy
  • Lateral Epicondylitis (Tennis Elbow)
  • Medial Epicondylitis (Golfer’s Elbow)
  • Bone fractures
  • Reduced weight-bearing protocols
  • Generalized weakness and deconditioning

Benefits of Blood Flow Restriction Training:

  • Improved athletic performance
  • Improved cardiovascular endurance (VO2 Max)
  • Increased strength and muscle growth
  • Decreased muscle soreness as compared to traditional strengthening
  • Faster bone healing times
  • Increased collage and protein synthesis
  • Increased tendon thickness/stiffness

Here’s what some of our patients had to say...

I started PT after a car accident. The staff was extremely helpful not just with injuries from the accident, but also other issues that had been bothering me. They are very good at communicating problems and solutions and are friendly to boot. Can’t recommend enough.

five stars Kevin RET Patient

Attentive, responsive, pleasant in communication, knowledgeable staff. I got good results in a short time. Thankful to Dr. Andrew for useful information and for a program of exercises.

five stars Elena RET Patient

Doug Free, the manager at Mercer Island Physical Therapy, has a PhD in PT, and is an amazing diagnostic doctor who explains why a specific injury occurred. He also does fabulous work on your body. His entire staff is knowledgeable and excellent therapists. 

five stars Gary RET Patient

I saw Anne at 7 weeks post ulnar nerve transposition. I’ve made more progress in 1 week with her than I did in those first 7.  She is extremely knowledgeable and up to date on current research.  I’d feel very good about sending my family and friends her way!

five stars Holli RET Patient

Kelly is amazing! I felt very comfortable and she asked all of the right questions, was super friendly, and knows exactly how to help. I always leave feeling so much better, and confident that if I do my exercises, I will heal!

five stars Kelsey RET Patient

Michelle has been amazing to work with. She quickly diagnosed the root cause of the issues that continued to plague me after recovering from hip replacement surgery that other PT’s (different companies) could not. She listens, is creative, resourceful, and very knowledgeable. Everyone at the clinic is always very professional and interested in our progress.

five stars Conrac RET Patient

I have been going to Summit Therapy for a shoulder problem. I’ve made steady progress and have gotten much pain relief. The staff is very friendly and great to work with. I recently had a sudden problem of vertigo. My therapist knew exactly what to do and performed a treatment that stopped the dizziness.
