PODCASTS | Owens Recovery Science | Blood Flow Restriction

In this episode, Johnny Owens and Dr. Luke Hughes discuss the applications of Blood Flow Restriction (BFR) in space and its potential to mitigate deconditioning in astronauts. They explore the physiological changes that occur in microgravity, the importance of exercise countermeasures, and the innovative research being conducted to understand the mechanisms behind BFR's effectiveness. The conversation also touches on the implications of BFR for bone health, clinical applications, and future research directions.

Takeaways

BFR is a promising tool for mitigating muscle and bone deconditioning in space.
Fluid shifts in microgravity can lead to significant health issues for astronauts.
BFR can enhance the effectiveness of low-intensity aerobic exercise.
Research is ongoing to understand the mechanisms behind BFR's benefits for bone health.
BFR protocols need to be personalized for different patient populations.
The use of BFR in clinical settings shows potential for improving recovery outcomes.
BFR can help prevent amputations in patients with severe vascular issues.
Understanding the impact of pressure on blood flow is crucial for optimizing BFR protocols.
BFR can be integrated into rehabilitation programs for various conditions.
Future research will focus on the long-term effects of BFR in both space and clinical settings.

This conversation explores the advancements in Blood Flow Restriction (BFR) technology, personal anecdotes related to injury recovery, and insights from recent conferences. The speakers discuss the significance of chronic ankle instability in sports, the effectiveness of BFR in enhancing muscle activation during rehabilitation, and the importance of interdisciplinary collaboration in sports medicine. They also reflect on their experiences and the evolving nature of BFR technology, emphasizing the need for continuous research in this field. This conversation delves into the application of blood flow restriction (BFR) training in rehabilitation, particularly focusing on its effects on muscle activation, balance training, and the challenges faced in research. The speakers discuss various studies, their methodologies, and the implications of using BFR in clinical settings, especially for ankle rehabilitation. They explore the differences between internal and external loads, the importance of programming, and the potential benefits of mobilization techniques combined with BFR. The discussion highlights the need for further research and standardization in BFR protocols to optimize rehabilitation outcomes.

In this episode of the Owens Recovery Science podcast, hosts Kyle Kimbrell and Zac Dunkle discuss the significance of Memorial Day, and share humorous military anecdotes. They emphasize the importance of supporting veterans and Gold Star families, highlighting various foundations that provide assistance and resources for those in need. The conversation blends humor with serious reflections on sacrifice, mental health, and community support.

We answer a listener question about how to manage a limb that is non-weightbearing for a period of time.

Kyle goes on an epic rant about what we can and can't do to care for our patients / clients.

In this episode of the ORS podcast Johnny and Kyle discuss all things PT and career trajectory as well as managing knee cartilage repairs with Snay Patel, PT. Snay is a PT at HSS and has an extensive background in the rehab of people following knee cartilage procedures. Let us know what you think of the pod an who we should have on next!

In this episode of the Owens Recovery Science podcast, Johnny and Kyle interview Annie Bane, PhD regarding her research into people with Parkinson’s Disease and the use of Blood Flow Restriction Resistance Exercise as a maintenance strategy. Dr. Bane is a wealth of knowledge on how treatment strategies and the disease progression of PD affect the cardiovascular system. This was ultimately the target of her dissertation research while at Baylor and her findings are very exciting. We know you will enjoy this chat!

If you know someone in the Abilene area that could benefit from the exercise program for people with Parkinson’s please have them email Jill Jumper, PT, PhD at Jill.jumper@hsutx.edu

If you would like to see Dr. Bane's TV show on she and her husband's gym in Abilene, TX the show is called "The Fieldhouse". It aired on the Magnolia Network and can now be found on Amazon Prime too.

If you jump in your wayback machine you can find our first episode with our distinguished guest on this installment of the Owens Recovery Science Podcast! And just like the first time she did not disappoint! Sherry Johnson, DVM, PhD, DACVSMR is a sports medicine physician for equine athletes. That's right y'all! Literal horses. She co-owns a private practice specializing in the care of very elite athletic horses that run the gamut event types with locations in Texas and Arizona. In her spare time!! She does BFR research. Well I'm tired just from typing that! Hope y'all enjoy our chat. Below are two of her BFR papers on horses.

In episode 65 Johnny makes his triumphant return after defeating Montezuma’s revenge to help the guys breakdown a couple recent publications on BFR and rehab after ACLr. Zac takes the lead on the first of the papers that had a bit of a clickbait title per the fellas assessment. The paper titled, “‘Real world’ clinical implementation of blood flow restriction therapy does not increase quadriceps strength after quadriceps tendon autograft ACL reconstruction” has a number of demographic problems the fellas discuss, and ultimately evaluated one of the least relevant outcome measures by their estimation. Kyle finishes up the breakdown with some alternate and far more accurate title suggestions for the paper.

The second paper they discuss was a recent review paper on ACL and BFR. Ben takes the lead breaking down this paper where the fellas have a tough time sorting why some studies were excluded and why at least one was included. Long story short the evidence on BFR use in ACLr rehab is still very limited and a review focusing on most all aspects of that process should be read with a healthy level of skepticism.
