Over the last 10 years, our research team (International Spine and Pain Institute; Therapeutic Neuroscience Research Group) has explored one such potential cause and set in motion a variety of research projects aimed at teaching people more about pain.3
Traditional medicine is strongly rooted in a biomedical model.4, 5 The biomedical model assumes that injury and pain are the same issue; therefore, an increase in pain means increased tissue injury and increased tissue issues lead to more pain. This model (called the Cartesian model of pain) is over 350 years old, and it's incorrect.1
Compounding the issue, the tissue model is then also used to teach patients why they hurt. For example, a patient presents at the clinician’s office with low back pain that significantly limits his function and movement. In this scenario, the clinician grabs the nearest spine model and explains to the patient that the reason he is hurting is due to a “bad disc” or “certain abnormal or faulty movement.” Now the model is set in place: correct the faulty tissue or movement and pain will go away.6 Not only does this model not work, but it actually increases fear and anxiety. Words like "bulging," "herniated," "rupture" and "tear" increase anxiety and make people less interested in movement, which is essential for recovery. Our research team contends that this approach contains a blatant flaw. When people seek treatment for pain, why teach them about joints and muscles? We should teach them about pain. This approach of teaching people about joints when they have pain does not make sense, and in fact does not answer the big question: Why do I hurt?7 This is especially true when pain persists for long periods; we know most tissues in the human body heal between 3-6 months.1 It is now well established that ongoing pain is more due to a sensitive nervous system. In other words, the body’s alarm system stays in alarm mode after tissues have healed.8
Our research has shown that people in pain are interested in pain, especially in regard to how pain works.9 Learning the biological processes of pain is called neuroscience education (the science of nerves). Since educating people about the science of nerves in regards to pain has a positive therapeutic effect, we decided to use the term Therapeutic Neuroscience Education (TNE). Based on a large number of high-quality studies, it has been shown that teaching people with pain more about the neuroscience of their pain (TNE) produces some impressive immediate and long-term changes.1, 3, 10, 11, 12, 13, 14, 15, 16
- Pain decreases
- Function improves
- Fear diminishes
- Thoughts about pain are more positive
- Knowledge of pain increases
- Movement improves
- Muscles work better
- Patients spend less money on medical tests and treatments
- The brain calms down, as seen on brain scans
- People are more willing to do much-needed exercise
How and why does this work? First, therapeutic neuroscience education changes a patient’s perception of pain. Originally, a patient may have believed that a certain tissue was the main cause for their pain. With TNE, the patient understands that pain may not correctly represent the health of the tissue, but may be due to extra-sensitive nerves. Second, fear is eased, and the patient is more able and willing to move and exercise.
How do we do it? This is the fun part. Every time we show people what we do, we get nervous—it seems so simple. We have developed a way to take very complex processes of the nerves and brain and make them easy to understand. Once we have distilled the information into an easy-to-understand format and paired it up with some interesting visuals, it becomes easy for everyone to understand. This includes patients of all ages, education levels, ethnic groups, etc. Using interpreters, TNE can be used all around the world.
Here's a brief example of therapeutic neuroscience education in practice: Suzy is experiencing pain and believes her pain is due to a bad disc. However, the pain has been there for 10 years. It is well established that discs reabsorb between 7-9 months and completely heal.17,18, 19, 20, 21 So, why would it still hurt? She believes (as she has been told by clinicians) that her pain is caused by a bad disc. Now, we start explaining complex pain issues via a story/metaphor with the aim to change her beliefs, and then we set a treatment plan in place based on the new, more accurate neuroscience view of pain.
Therapist: “If you stepped on a rusted nail right now, would you want to know about it?”
Patient: “Of course.”
Patient: “Well; to take the nail out of my foot and get a tetanus shot.”
Therapist: “Exactly. Now, how do you know there’s a nail in your foot? How does the nail get your attention?”
Therapist: “The human body contains over 400 nerves that, if strung together, would stretch 45 miles. All of these nerves have a little bit of electricity in them. This shows you’re alive. Does this make sense?”
Therapist: “The nerves in your foot are always buzzing with a little bit of electricity in them. This is normal and shows….?”
Patient: “I’m alive.”
Therapist: “Yes. Now, once you step on the nail, the alarm system is activated. Once the alarm’s threshold is met, the alarm goes off, sending a danger message from your foot to your spinal cord and then on to the brain. Once the brain gets the danger message, the brain may produce pain. The pain stops you in your tracks, and you look at your foot to take care of the issue. Does this sound right?”

Therapist: “Once we remove the nail, the alarm system should…?”
Patient: “Go down.”
Therapist: “Exactly. Over the next few days, the alarm system will calm down to its original level, so you will still feel your foot for a day or two. This is normal and expected."
Therapist: “Here’s the important part. In one in four people, the alarm system will activate after an injury or stressful time, but never calm down to the original resting level. It remains extra sensitive. With the alarm system extra sensitive and close to the “firing level,” it does not take a lot of movement, stress or activity to activate the alarm system. When this happens, surely you think something MUST be wrong. Based on your examination today, I believe a large part of your pain is due to an extra-sensitive alarm system. So, instead of focusing of fixing tissues, we will work on a variety of strategies to help calm down your alarm system, which will steadily help you move more, experience less pain and return to previous function."

The example above is just one story/metaphor we use to teach patients about complex processes like injury, inflammation, nerves waking up, extra-sensitive nerves, brain processing information, pain produced by the brain, etc. It seems quite simple, but it's complex. The crucial part is that patients are easily able to understand the example and better yet, the principle. Subsequently, a significant shift occurs. Instead of only seeing pain from a “broken tissue” perspective, they see pain from a sensitive nervous system perspective. Simply stated, they understand they may have a pain problem rather than a tissue problem. Now, the fun starts. If you're the fifth therapist a chronic pain patient has seen, he or she will likely have little hope that you will be able to help, since your treatment will likely be the same as the others. This neuroscience view of sensitive nerves versus tissue injury allows for a new, understandable view of treatments aimed at easing nerve sensitivity, such as aerobic exercise, manual therapy, relaxation, breathing, sleep hygiene, diet and more.
When a patient learns more about pain and how pain works, their pain eases considerably and they experience a variety of other benefits, such as increased movement, better function and less fear. These effects are measurable and we believe they can do more than some of the most powerful drugs in the world, without any of the side-effects. Look at the picture below (Louw A, et. al 2014 – submitted for publication). It’s a brain scan we performed on a high-level dancer experiencing significant back pain for almost two years. She was scheduled for back surgery in two days and was nervous and anxious.
Row 1: She was in the scanner, relaxing and watching a movie. You will notice you there are no red "blobs."
Row 2: We asked her to move her painful back while in the scanner. The scanner picks up activity of the brain and displays it as red blobs. Without being too technical, the more red blobs we see, the more pain she was experiencing. Therefore, Row 2 shows her brain while she is having pain during spine movements.
Row 3: After Row 2’s scans (red blobs), we took her out of the scanner and spent 20-25 minutes teaching her more about pain, as we describe earlier. After the education session, we re-scanned her brain doing the same painful task as performed in Row 2. This time, however, there is significantly less activity, fewer red blobs, while doing the same painful task as before.
This is a graphic representation of how teaching people about pain helps ease pain. It works. Know pain; know gain.
