The Psychology of Pain | Dr Tom Walters
Dr. Tom Walters discusses how pain is a brain output rather than purely a sensory phenomenon, explaining the role of psychological factors like nocebo effects in worsening outcomes, and provides evidence-based guidance on movement, strength training, and lifestyle factors for managing pain and preventing injury.
Summary
This episode features Dr. Tom Walters, an orthopedic physical therapist and author of 'Rehab Science,' discussing the modern understanding of pain and injury recovery. The conversation begins with foundational pain science, explaining that pain has both sensory and emotional components and is generated by the brain rather than simply transmitted from damaged tissues. Research on phantom limb pain and visual perception studies (such as the red light/blue light temperature experiment) demonstrate that the brain can create pain based on perceived threat rather than actual tissue damage.
Walters and the host explore how healthcare providers can inadvertently harm patients through language choices—a concept called the nocebo effect (the opposite of placebo). Examples include doctors using scary language when describing MRI findings, which creates fear and anxiety that worsens rehabilitation outcomes, even when structural findings are common in pain-free individuals. The research shows that nearly half the population has meniscus tears, bulging discs, and other degenerative findings without any symptoms.
The discussion then shifts to practical movement and exercise guidance. Walters outlines that most musculoskeletal conditions improve with time and appropriate movement rather than rest or immobilization. He emphasizes that strength training is the most important exercise intervention for injury prevention and pain management, more so than mobility or flexibility work alone. He recommends a weekly structure of daily walking (10,000 steps), strength training 3-4 days per week for 20-30 minutes minimum, and optional cardiovascular work.
For those with existing pain, Walters describes a progressive approach including soft tissue mobilization, mobility/flexibility work, and neuromuscular control exercises before advancing to strength training. He introduces the concept of load management and progressive overload, explaining how the body adapts to mechanical stress when increased gradually. The conversation covers specific topics like foam rolling (5-10 passes followed by sustained pressure on trigger points), the importance of movement quality and motor control before adding external load, and how even explosive movements like jumping should be introduced progressively.
Walters addresses common myths, such as weight training stunting growth in children, which research clearly refutes. He also discusses the difference between actual tissue damage and potential tissue damage (based on belief), explaining how pain can exist without injury and injury can exist without pain. The episode covers why certain interventions like chiropractic adjustments can be helpful if framed correctly but problematic if they create treatment dependency. Throughout, the emphasis is on self-efficacy—empowering people to manage their own symptoms rather than becoming dependent on practitioners.
About this episode
<p><strong>How much of the time you spend in pain comes from the injury itself, and how much comes from the fear around it?</strong></p><p>Dr. Tom Walters is a board-certified orthopedic physical therapist, strength and conditioning specialist, educator, and founder of Rehab Science. He has spent more than two decades helping people understand pain, movement, and injury recovery, and he is the author of Rehab Science: How to Overcome Pain and Heal from Injury.</p><p>Tom’s starting point is that pain and injury are not the same thing. Pain is an unpleasant sensory or emotional experience tied to actual or potential tissue damage, which means what you believe about your body can change what you feel in it.</p><p>Tom and Mike get into the nocebo effect, how a clinician’s words or reaction to a scan can amplify pain, why the field traded the word chronic for persistent, and how to manage exercise loads as your body adapts.</p><p>Mike tells the story of an MRI he had around the age of 23. The doctor looked at the film, his eyes got big, and he asked if Mike was okay. Mike says his pain felt worse instantly.</p><p>Tom says many musculoskeletal conditions improve with time and movement. He encourages people to take an active role in recovery: try an appropriate movement, notice how your body responds, and adjust from there.</p><p>Enjoy the conversation.</p><p>___________________________________________________________________</p><p><strong>Links & Resources:</strong></p><p><strong>Dr. Tom Walters’ Website: </strong><a href="https://rehabscience.com" rel="noopener noreferrer" target="_blank">rehabscience.com</a></p><p><strong>Dr. Tom Walters’ Books: </strong><em>Rehab Science: How to Overcome Pain and Heal from Injury</em>, plus the 2026 Rehab Science body-region series: <em>Knee, Back and Spine, Hip, Shoulder, Elbow, Wrist & Hand, Ankle and Foot, and Head & Neck</em></p><p><strong>Dr. Tom Walters’ YouTube Channel: </strong><a href="https://www.youtube.com/@RehabScience" rel="noopener noreferrer" target="_blank">Rehab Science</a></p><p><strong>The Rehab Science App: </strong><a href="https://apps.apple.com/us/app/rehab-science/id6752273938" rel="noopener noreferrer" target="_blank">Rehab Science on the App Store</a></p><p><strong>Subscribe</strong> to our Youtube Channel for more conversations at the intersection of high performance, leadership, and wellbeing: <a href="https://www.youtube.com/c/FindingMastery" rel="noopener noreferrer" target="_blank">https://www.youtube.com/c/FindingMastery</a></p><p><strong>Get exclusive</strong> discounts and support our amazing sponsors!</p><p><strong>Go to: </strong><a href="https://findingmastery.com/sponsors/" rel="noopener noreferrer" target="_blank">https://findingmastery.com/sponsors/</a></p><p><strong>Subscribe</strong> to the Finding Mastery newsletter for weekly high performance insights: <a href="https://www.findingmastery.com/newsletter" rel="noopener noreferrer" target="_blank">https://www.findingmastery.com/newsletter</a></p><p><strong>Download</strong> Dr. Mike’s Morning Mindset Routine: <a href="https://www.findingmastery.com/morningmindset" rel="noopener noreferrer" target="_blank">findingmastery.com/morningmindset</a></p><p><strong>Follow</strong> on <a href="https://www.youtube.com/findingmastery" rel="noopener noreferrer" target="_blank">YouTube</a>, <a href="https://www.instagram.com/findingmastery/?hl=en" rel="noopener noreferrer" target="_blank">Instagram</a>, <a href="https://www.linkedin.com/in/drmichaelgervais/" rel="noopener noreferrer" target="_blank">LinkedIn</a>, and <a href="https://x.com/michaelgervais" rel="noopener noreferrer" target="_blank">X</a></p><p>See Privacy Policy at <a href="https://art19.com/privacy" rel="noopener noreferrer" target="_blank">https://art19.com/privacy</a> and California Privacy Notice at <a href="https://art19.com/privacy#do-not-sell-my-info" rel="noopener noreferrer" target="_blank">https://art19.com/privacy#do-not-sell-my-info</a>.</p>
Key Insights
- Pain is an output of the brain rather than purely a signal from damaged tissues, as evidenced by phantom limb pain research showing pain in body parts that no longer exist.
- Visual information and meaning significantly influence pain perception; studies show that when people see a red light (associated with heat) before touching a cold rod, they report more pain than with a blue light, even though the temperature is identical.
- Healthcare providers unintentionally harm patients through negative framing of findings, as the word 'chronic' and scary descriptions of MRI results create fear and anxiety that worsens rehabilitation outcomes.
- Approximately half of pain-free individuals have structural findings like meniscus tears, bulging discs, and degenerative changes on MRI, meaning structural abnormalities do not correlate with pain or symptoms.
- Most musculoskeletal conditions improve with time alone, and clinicians often take credit for improvements that would occur naturally without intervention—a phenomenon called regression to the mean.
- Strength training is the single most evidence-supported intervention for reducing injury risk and managing pain, more so than mobility or flexibility training alone.
- Any static posture held for long periods activates nociceptors (danger receptors) through muscle ischemia and reduced blood flow, regardless of whether the posture is considered 'good' or 'bad'.
- The body's musculoskeletal system adapts to mechanical loading by making tissues denser, thicker, and more resilient—even spinal discs of weightlifters are thicker than non-weightlifters.
- Jumping and plyometric movements are necessary for bone density gains, while walking and running alone do not sufficiently stress bones to trigger adaptive responses.
- Youth weight training does not stunt growth or close growth plates; the myth likely stems from historical misconceptions about the dangers of weight training rather than actual research.
- Meniscus surgery and sham surgery show equal pain reduction outcomes when patients don't know which group they're in, suggesting surgery's effectiveness is partly driven by placebo mechanisms.
- Graded exposure—gradually introducing movement that mimics painful activities in small doses—allows people to expand their capacity to tolerate stress without exacerbating symptoms.

Transcript
For hundreds of years pain was believed to be this sensory phenomena that came from your tissues of your body. That really has changed through this research. A lot of it was on phantom limb pain on people who had lost a part of their limb but still had pain. That piece of the body is not there anymore so you can't think of it as just coming straight from those tissues. They could not have a signal from the hand that didn't exist. Exactly and so that research really drove a lot of the changes of thinking about pain as sort of more of a top-down and output of the brain. Board-certified orthopedic physical therapist and strength and conditioning…
