Understanding Pain: How Chiropractic and Physiotherapy Help Manage Pain Through Modern Science
Pain is one of the most misunderstood and complex experiences we face. It’s not just a simple warning system — it’s a highly sophisticated and adaptive response involving the nervous system, brain, emotional state, and even past experiences. To manage pain effectively, it’s crucial to understand the types of pain, how we perceive it, and how chiropractic care and physiotherapy can manipulate this process for relief.
The Complex Nature of Pain
Pain can be broadly divided into several types:
- Acute Pain: Short-term pain that typically occurs after injury or surgery, serving as a protective mechanism.
- Chronic Pain: Lasting longer than 3 months, often persisting even after the original injury has healed.
- Neuropathic Pain: Caused by nerve damage or dysfunction.
- Nociceptive Pain: Results from activation of nociceptors due to tissue injury or inflammation.
- Referred Pain: Pain felt in an area distant from the actual source of injury.
Pain is not just a direct line from the injured area to the brain. It is modulated, amplified, or muted by the nervous system depending on factors like stress, emotional health, prior injuries, and social context.

How We Sense Pain: Nociceptors and Mechanoreceptors
Nociceptors are specialized sensory receptors that detect harmful stimuli such as extreme temperatures, mechanical forces, or chemical irritants. Once activated, they send electrical signals through peripheral nerves to the spinal cord and brain, where pain is consciously perceived.
In contrast, mechanoreceptors detect touch, vibration, pressure, and proprioception (the sense of body position). Interestingly, when mechanoreceptors are activated, they can actually inhibit pain transmission — a phenomenon explained by the Pain Gate Theory.
To dive deeper into the biology of pain, see this NCBI resource on Pain Mechanisms.
Pain Gate Theory: Shutting the Gate on Pain
The Pain Gate Control Theory, introduced by Melzack and Wall, suggests that there is a “gate” mechanism in the spinal cord that either allows or blocks pain signals from reaching the brain.
When non-painful stimuli — like touch, pressure, or movement — activate mechanoreceptors, they “close the gate” to painful stimuli. This reduces the intensity of pain experienced.
This explains why rubbing a bumped elbow, receiving a spinal adjustment, or engaging in light exercise often leads to a noticeable reduction in pain.

How Chiropractic and Physiotherapy Influence Pain
Both chiropractic and physiotherapy use targeted techniques to influence the way pain is perceived and processed in the body. Here’s how:
Spinal and Joint Manipulations
- Chiropractic adjustments and manual therapy stimulate mechanoreceptors.
- This stimulation “closes the gate” on pain signals, reduces muscle guarding, and improves joint function.
Soft Tissue Mobilization
- Trigger point therapy, dry needling, and myofascial release target tight or inflamed areas.
- These methods modulate local pain responses and normalize tissue function.
Movement Therapy and Exercise
- Corrective exercise desensitizes the nervous system, improves load tolerance, and retrains the brain’s interpretation of movement and threat.
- Chiropractic & Physiotherapy services often emphasize graded exposure to movement to rebuild strength and confidence.
Neuromodulation
- Tools like IFC (Interferential Current Therapy) and ultrasound therapy alter nerve signal transmission at the local level, offering additional pain relief.
Pain is Not Always Damage
One of the most important understandings from modern pain science is this: pain does not always equal injury.
Especially in chronic pain cases, your nervous system can become overly sensitive. You might feel significant pain even though your tissues are healed or minimally injured.
Effective chiropractic and physiotherapy treatments focus not just on the injured tissues but also on calming and retraining an overactive nervous system.
Conclusion: Moving Beyond Pain
Pain is a complex, multi-dimensional experience influenced by the nervous system, brain, and even emotions. By understanding concepts like nociceptors, mechanoreceptors, and the Pain Gate Theory, it becomes clear why chiropractic care and physiotherapy are effective tools in managing pain — not just by fixing structural problems, but by influencing how pain is experienced and processed.
If you’re struggling with acute or chronic pain, don’t just mask it — address it at the root.

Frequently Asked Questions About Pain Management
Q1: Does chiropractic adjustment help with chronic pain?
Yes. Chiropractic adjustments can help manage chronic pain by stimulating mechanoreceptors, improving joint mobility, and modulating how your nervous system processes pain signals through mechanisms like the Pain Gate Theory.
Q2: How does physiotherapy help reduce pain?
Physiotherapy combines movement therapy, soft tissue mobilization, and neuromodulation techniques to desensitize nerve endings, promote healing, and retrain your body’s perception of pain.
Q3: Is pain always a sign of injury?
No. Especially in cases of chronic pain, your nervous system can become hypersensitive, causing pain without active tissue damage. Understanding this is key to effective treatment.
