Pain is something that everyone experiences, but very few people truly understand. The truth is, pain isn't just about physical injury or tissue damage. It’s a complex process influenced by many factors, including the brain, emotions, and past experiences. In this blog, we’ll explore the Explain Pain model by Butler and Moseley, which has revolutionized how we understand and treat pain. Whether you're struggling with chronic pain or simply want to know more, understanding pain science can be a powerful tool in your journey toward better health.
The Power of Understanding Pain
Pain is a critical protective mechanism, but it’s also incredibly complex. The Explain Pain model helps us realize that pain is not just a reaction to physical injury but also a response shaped by the brain's perception of danger. This insight is not only enlightening but also useful for managing pain. Research has shown that explaining pain to patients can significantly improve outcomes. In fact, the number needed to treat (NNT) to get a positive result from educating a patient about pain is just three—that means for every three people you educate, one person will experience pain relief within a year.
To put this in perspective, most medications have a much higher NNT. For example, the NNT for taking aspirin to prevent a heart attack is somewhere between 50 and 500, depending on the study you read! This highlights the power of knowledge in managing and understanding pain.
Pain: A Message from the Brain, Not Just the Body
Pain isn’t always what it seems. While tissue damage can cause pain, pain doesn’t always correlate with injury or damage. For example, people with herniated discs or other "serious" conditions often experience pain, but the severity of the injury doesn't always match the pain level. This is because pain is a response of the brain, not just a direct reaction to physical damage.
The brain constantly assesses the level of danger you're in. If your brain perceives a high level of threat—whether from physical injury, emotional stress, or past trauma—it can generate pain. Pain is essentially a protective device designed to alert you to danger, but it can sometimes be overly sensitive.
As pain persists, the nervous system can become more efficient at generating pain, even when there is no new injury. This is what we call central sensitization, a phenomenon where the nervous system amplifies pain signals, making pain more intense or prolonged than it should be.
The Biomedical vs. Biopsychosocial Models of Pain
Historically, pain has been treated using the biomedical (BM) model, which focuses on anatomy, biomechanics, and tissue pathology. While this model has its place—especially when dealing with serious conditions like cancer or fractures—it doesn’t tell the whole story.
The biopsychosocial (BPS) model, which includes both biological and psychological factors, provides a more complete understanding of pain.
The BPS model takes into account not just the physical damage but also the emotional, social, and cognitive factors that contribute to pain. For example, stress, anxiety, and negative thoughts can worsen pain, while a positive mindset, physical activity, and education about pain can help alleviate it. Pain is complex, and multiple factors interact to create the pain experience.
The Neuroimmune System and Pain
When we think about pain, we often focus on the body’s tissues and nerves. However, pain is also deeply linked to the immune system. For example, inflammation is a natural immune response to injury, but it can also contribute to prolonged pain if it becomes chronic. The neuroimmune system, which includes the brain, nerves, and immune cells, plays a critical role in pain perception.
Nociception is the process by which the body detects potential harm, but this “danger signal” is not the same as pain. Pain is the brain's interpretation of that signal. The body’s immune cells, including those in the nervous system, can become “sensitized,” making the body more sensitive to pain over time.
How Central Sensitization Affects Pain
One of the most important concepts in modern pain science is central sensitization. This occurs when the central nervous system (CNS) becomes overly sensitive, amplifying pain signals. In this state, even minor inputs, like a light touch or mild movement, can trigger intense pain. This can happen after an injury or illness, but it can also occur in the absence of any tissue damage.
Central sensitization can result in abnormal pain responses and contribute to chronic pain. For example, people with chronic pain conditions often experience more intense pain than what would be expected based on their injuries or conditions. The good news is that central sensitization is reversible, and with the right treatment, the nervous system can “reset,” reducing pain sensitivity.
Teaching Patients About Pain: A Therapeutic Approach
Explaining pain to patients in a way they can understand is key to helping them manage their pain. The Explain Pain model encourages a patient-centered approach, starting by understanding the patient's story. It’s essential to meet the patient where they are and use language, metaphors, and stories that resonate with them.
One of the most powerful ways to explain pain is through metaphors. These help patients reframe their understanding of pain and shift their perspective. Here are some examples:
Simple Metaphors: “Your knee is like a rusty hinge.” This can help explain joint pain or stiffness.
Ontological Metaphors: “Pain is a killer.” This can be reframed to help the patient understand that pain is not permanent, and it doesn’t define their entire existence.
Therapeutic Metaphors: “Motion is lotion.” This simple metaphor highlights the importance of movement in reducing pain and promoting healing.
By using metaphors and stories, we can help patients reconceptualize their pain, giving them a greater sense of control and understanding. This process can help reduce the fear and anxiety that often accompany chronic pain.
