The Strength Gap Physical Therapy Keeps Missing

Pain can improve. Range of motion can return. A patient can pass testing and still leave rehabilitation without the strength or reserve required by sport, work, or daily life.Using persistent quadriceps weakness after ACL reconstruction as the opening example, Lou Fullenkamp examines the difference between giving someone an exercise and building an actual training stimulus. The discussion covers underdosing, load and effort, the limitations of manual muscle testing, progression toward meaningful intensity, and why late-stage rehabilitation should borrow more deliberately from strength and conditioning.The goal is not indiscriminate heavy loading. It is matching the dose to the adaptation once tissue tolerance allows.

Passing return-to-sport testing is not the same as restoring performance.In this episode, Louis Fullenkamp is joined by Tommy Otley, Lead Physical Therapist and Sport Scientist for the University of Miami men’s and women’s basketball programs.Tommy explains why medical clearance should be viewed as a transition—not the finish line. They discuss the limitations of rigid testing batteries, the value of individualized assessment, and the challenge of determining whether an athlete is prepared for the speed, workload, variability, and competitive demands of sport.The conversation also explores collaboration between rehabilitation and performance staff, monitoring athletes after clearance, practical testing options for clinicians without elite-level resources, and why the goal of rehabilitation should extend beyond returning an athlete to participation.Tommy also shares lessons from his sports residency and Division I Athletics Fellowship at Duke University, his path into collegiate sports medicine, and his PhD research on restoring meaningful competitive performance after injury.Connect with Tommy:Website: https://www.tommyotley.com/The Film Room: https://www.tommyotley.com/blogResources: https://www.tommyotley.com/resourcesInstagram: https://www.instagram.com/tommy_otley_dpt/LinkedIn: https://www.linkedin.com/in/tommy-otley-dpt/

An athlete completes a return-to-sport testing battery. Strength looks good. Hop testing looks good. Limb symmetry is above 90%. The athlete passes—and everyone assumes that means the athlete is ready.Then the athlete gets hurt again.In this solo episode, Lou Fullenkamp examines why passing return-to-sport testing does not guarantee safety. He breaks down the limitations of limb symmetry index, explains why the uninvolved limb can be an unreliable reference point, and explores what controlled hop and strength tests may fail to capture about actual sport.The episode also examines fatigue, unpredictability, cognitive load, psychological readiness, and the often poorly managed transition between discharge from physical therapy and full reintegration into training and competition.Testing remains valuable. The problem is the certainty we attach to it.Instead of asking only, “Did the athlete pass?” clinicians should also ask, “What does this testing tell us—and what does it still leave unanswered?”

In this episode of The Lab Collective, Lou sits down with Paul Clingan creator of Fit For The Republic to discuss discipline, identity, consistency, and the role community plays in long-term fitness success. We explore how storytelling influences fitness culture, how adopting an alter ego can help people pursue growth and accountability, and how building a strong sense of identity can help people stay aligned with the person they want to become.Check out Fit For The Republic today!Paul Clingan – Fit For The RepublicMain Page:https://fitfortherepublic.com/21 Day Cadet Fitness Challenge:https://fitfortherepublic.com/21day-cfcYouTube Page:https://www.youtube.com/@FitForTheRepublicInstagram:https://www.instagram.com/fit_for_the_republic/

Do you feel trapped by productivity standards, documentation, insurance limitations, or the traditional physical therapy career path?You may be stuck in the Physical Therapy Matrix. In this episode of The Lab Collective Podcast, I discuss the mindset that keeps many clinicians feeling stuck and the steps you can take to build a career with more freedom, purpose, and opportunity.-Why therapists often feel trapped-The hidden assumptions that limit career growth-How expertise creates freedom-Financial and professional independence-Building opportunities through teaching, networking, and content creation-My own journey through clinical practice, leadership, education, strength and conditioning, and podcastingThis isn't an episode about leaving physical therapy. It's about realizing you have more options than you think. The degree opens the first door. The rest are opened by curiosity, relationships, and initiative.🎙️ The Lab Collective Podcast explores sports medicine, rehabilitation, performance, strength and conditioning, and professional development for clinicians looking to bridge the gap between rehab and performance.#PhysicalTherapy #SportsMedicine #SportsPT #SportsRehab #StrengthAndConditioning #CareerDevelopment #TheLabCollective

In this episode, Lou sits down with Adelaide Cooke Sperling, a third-generation physical therapist specializing in pelvic health and sports medicine. Adelaide, a former D1 track and field athlete at the University of Albany, discovered pelvic floor physical therapy while studying at Northwestern University.The discussion focuses on pelvic health in athletic populations, emphasizing the importance of addressing pelvic floor issues across all genders and ages. Adelaide shares her expertise as both a physical therapist and former athlete, covering topics such as Relative Energy Deficiency in Sports (RED-S), sacroiliac joint pain, and pregnancy/postpartum considerations.The conversation highlights the need for healthcare providers to feel comfortable discussing sensitive topics and conducting thorough assessments.

In this episode of The Lab Collective, Louis sits down with Mohamed, a Physical Therapist for the New Orleans Saints, to unpack his journey from PT school to the NFL sidelines. They dive into the pivotal career choices that shaped his path, discuss the differences between private practice and professional sports, and explore what it truly takes to thrive in elite-level sports medicine. Mohamed shares valuable insights on collaboration, adaptability, and the unique demands of working with pro athletes. Whether you're a student, clinician, or sports enthusiast, this episode offers a rare look behind the curtain of NFL sports medicine.

In this episode of The Lab Collective, Louis and Alex unpack the underrated power of isometric training for athletes. They break down the science behind yielding vs. overcoming isometrics, discuss how to strategically use them for strength gains, tendon health, and injury resilience, and explore how to implement them across sports like football and track. Whether you’re pushing through sticking points or dialing in neuromuscular control, this conversation reveals how isometrics can become a foundational tool in your programming toolbox—without overloading the joints. Learn how to train harder and smarter.

In this episode of The Lab Collective, Dr. Lou Fullenkamp explores the importance of autoregulation and flexible non-linear programming in training and rehab. He emphasizes that training should adapt to the athlete or patient, not the other way around. Lou introduces key autoregulation tools like Rate of Perceived Exertion (RPE), Reps in Reserve (RIR), and Velocity-Based Training (VBT) as practical ways to assess daily readiness and adjust training on the fly. He explains how Flexible Non-Linear Programming (FNLP) moves beyond rigid, linear periodization models making it a powerful system for athletes in-season, post-injury patients, and everyday lifters managing life’s unpredictability. Lou highlights real-world coaching examples, stressing the importance of understanding each individual’s physical and emotional state before proceeding with the Rx intensity or volume.The episode closes with a reminder to listen to athletes and patients, fostering meaningful conversations about how they feel and what they need each day. Lou invites listeners to stay connected with The Lab Collective for more insights and encourages them to join the conversation through social media and email.
