    Ep 127: The 490,000-Athlete Dataset Changing How We Train and Rehab

    In this episode of The Undercurrent Podcast, Garrett sits down with Dr. Trent Nessler, a physical therapist, biomechanics researcher, and founder of The Athlete Lab in Franklin, Tennessee. Over 28 years in practice, Trent has built one of the most comprehensive movement-data engines in the world: the ViMove+ AMI wearable sensor system, which has now captured over 4,700 data points per assessment on more than 490,000 athletes across five countries. What he's learned from that dataset is rewriting how we think about injury risk, ACL rehab, and return to play. In this conversation, we cover:                                  The profound role of pelvic stability and dynamic valgus speed in predicting ACL injury Fatigue-state training and why the ACL Play It Safe program works best after practice                                                                                    How Trent integrates NEUBIE, BFR, biologics, red light therapy, and nutrition into a truly holistic rehab model                                                         Lessons from assessing thousands of firefighters, police, and Special Operations personnel                                                       The role of mindset, hope, and a warrior ethos in recovering from catastrophic injury                                                                                       Whether you're a clinician, coach, athlete, or tactical operator, this conversation offers a rare look inside the mind of someone who has spent nearly three decades measuring, questioning, and refining what it actually takes to move – and heal – at the highest level.

    Ep 126: Stiff Hips, Slow Swing: The Missing Foundation in Your Golf Performance Pyramid

    Most golfers are chasing a better swing. But what if the real limitation isn't your technique, but your body? In this episode with Mike McDonnell, we break down the Golf Performance Pyramid and discuss why most players are building their game on an incomplete foundation. We cover: The Golf Performance Pyramid: mobility → stability → strength → power Why hip mobility (especially internal rotation) is a major limiter of speed and consistency How skipping foundational movement leads to compensation and injury The difference between training muscles vs training movement How to structure training year-round, including during competitive seasons If you want more distance, consistency, and longevity, don't just work on your swing … Fix the foundation it's built on.

    Ep 125: The Neurology of Movement: A Two-Way Street Between Brain and Biomechanics

    We often treat movement like a one-way equation: Brain → Body → Performance.  But in reality, it's a feedback loop. The body is constantly sending information back to the brain, and that information shapes how we move, perform, and recover.  In this conversation with Harry Worrow, we talk about his frameworks for working with everyone from athletes to individuals with neurodegenerative conditions, and how he uses biomechanical analysis paired with functional neurology. Specifically, we cover: The two-way relationship between neurology and biomechanics Why better sensory input leads to better movement output A deeper look at working with the visual and vestibular systems Why movement quality should come before load and intensity Strategies for long-term progression in neurodegenerative cases Movement is a blend of hardware and software, mechanics and neuroscience. Ultimately, it's shaped by how the nervous system interprets and responds to the world – and the good news is that this you can influence this process with the right techniques and strategies.

    Ep 124: The New Patient Pipeline: Breakthrough Strategies for Practice Growth

    What happens when physician referrals start disappearing? For Chad Madden, it forced a complete reinvention of how his practice attracted patients. That shift ultimately led to scaling his clinic to seven locations and co-founding Breakthrough to help hundreds of practices do the same. In this episode we discuss: The New Patient Pipeline and how it works The difference between clinician messaging and patient messaging Why direct response marketing works for healthcare The systems that turn cold leads into paying patients How cash-pay services are reshaping the economics of private practice The takeaway: Great care alone doesn't guarantee growth. You also need a system to create demand, and Chad shows us that system.

    Ep 123: From Managing Symptoms to Creating Solutions: Treatment Plans That Create Real Outcomes

    Most healthcare is built around managing symptoms. A little treatment here. A quick intervention there. "Let's try this and see how you respond." But what if the real problem isn't the pain – it's the system treating pain? In this episode, Dr. Mike Carberry and Colleen Carberry, PT, the founders of Advanced Medical Integration break down: Why symptom-based care keeps patients on the "train to drugs and surgery" How integrating physician care, chiropractic, and PT, compresses recovery time Why frequency and coordinated team care matter more than isolated visits How structured treatment plans drive measurable functional outcomes The systems that allow practices to scale without sacrificing results If you want better outcomes, you don't just need more visits. You need a better model.

    Ep 122: How Top 10% Practices Think, Lead, and Scale

    What separates a good practice from a top 10% practice? In this episode with Brian Gallagher, PT, we unpack the mindset shifts, leadership frameworks, and operational discipline that consistently show up in the highest-performing clinics. This isn't about hacks, it's about how elite operators think. Specifically, we discuss: The identity shift required to move from clinician to true business leader Why culture must be built intentionally, not accidentally The role of systems and accountability in sustainable growth How top practices approach hiring, retention, and performance standards The top few ways successful practices outsource to improve efficiency If you're a practice owner (or aspire to be one), this conversation will challenge you to raise your standards – not just clinically, but strategically. As you'll learn from Brian, the top 10% don't get there by luck. They build differently.

    Ep 121: Beyond Tissues: A Whole-System Approach to Healing

    Healing is rarely about fixing a single tissue or structure. In this episode, Lisa Chase, PT, shares the frameworks from her new book, Be Responsible, Because the System Isn't, and describes why true recovery depends on the health of the entire system – from the nervous system and sleep to lifestyle, resilience, and capacity. When the whole system is robust, healing becomes possible. When it's not, symptoms simply move around. In this conversation, we discuss: Why pain and injury are often downstream expressions of system overload How nervous system regulation shapes recovery, inflammation, and resilience The Pyramid of Healing and moving beyond symptom management What it means to rebuild health instead of chasing relief How tools like movement, lifestyle changes, and technology fit into a whole-system model This episode is an invitation to rethink healing. It's not something that's done to you, nor is it something done in isolation. Rather, healing is something that emerges when the whole system is supported.

    Ep 120: Relearning to Walk: One Family's Journey Through Functional Neurological Disorder

    What happens when a child suddenly loses the ability to walk – and the answers aren't structural, surgical, or pharmaceutical? In this episode, Garrett sits down with George James and Katie, the mother of 9-year-old Jodie, to share an extraordinary and deeply human story of Functional Neurological Disorder (FND), resilience, and recovery. In this conversation, we explore: Jodie's sudden onset of FND after fainting during a field hockey game, and the loss of walking, speech, and confidence The emotional and logistical journey of navigating a misunderstood condition George's decision to travel from the UK to Kenya for a 5-day intensive The clinical framework for approaching FND, including an emphasis on sensory input, play, and nervous system retraining  Broader takeaways from this story and what it teaches us about neuroplasticity, graded exposure, "deconstructing" movement patterns like gait, and more This story is an inspiring example of patience, trust, and the remarkable adaptability of the human nervous system, with some extremely valuable clinical insights mixed in.
