If you are living with pain that has lasted months or years, you are not alone. Persistent pain is one of the most common reasons Australians see a clinician, and it does not behave the way short-term pain does. The encouraging part is that decades of research point in a consistent direction: chronic pain management built around graded movement, education, and pacing helps most people improve how they function day to day.
01 · What it is
What chronic pain actually is
Pain comes in two broad types. Acute pain is short-term, usually less than three months, and is closely tied to tissue damage from an injury, surgery, or illness. Chronic pain is pain that persists for more than three months, often well after the original tissue has healed.
In chronic pain, the link between pain and tissue damage weakens. Pain stops being a reliable measure of what is happening in the body. It starts to behave more like an alarm system that has grown more sensitive over time. This is sometimes called central sensitisation. It is now widely accepted that this change in the nervous system is part of what keeps chronic pain going.
This does not mean the pain is imagined. The pain is real. What has changed is how the nervous system processes the signals, which is why scans and tests often come back clear in people with significant chronic pain.
02 · How it works
The biopsychosocial framework
To make sense of chronic pain, clinicians use the biopsychosocial framework. It describes pain as the result of three groups of factors working together.
- Biological factors. Tissue health, genetics, hormones, sleep, nervous-system sensitivity, and general fitness.
- Psychological factors. Beliefs about pain, mood, stress, fear of movement, and past experiences with pain.
- Social factors. Work, relationships, support networks, financial pressure, and access to care.
The point of the framework is not to assign blame to any one group. It is to recognise that all three shape how pain is felt and how the body responds. Two people with the same physical condition can experience very different pain because of differences in sleep, stress, or support around them.
This is also why a movement-only approach often falls short for persistent pain. Working on the biology alone, without considering sleep, stress, beliefs, or daily structure, leaves a lot of the picture out.
03 · The twin peaks model
Why movement helps: the twin peaks model of pain
One useful way to picture how the body’s protective system changes after an injury is sometimes called the twin peaks model. Before an injury, there is a level of activity the tissue can handle, called tissue tolerance, and a lower level at which the body starts producing pain as a warning. The gap between the two is small, and the pain signal lines up reasonably well with what the tissue can take.
After an injury, two things tend to change. Tissue tolerance can drop, because the tissue may be a little weaker or tire more easily than before. At the same time, the body’s protective threshold drops further still. The gap between “pain starts” and “tissue is actually at risk” gets wider. Pain now switches on at activity levels well below what the tissue could really handle.
This is why complete rest often does not help chronic pain, and can sometimes make it worse. The protective system needs gentle, repeated signals that movement is safe so it can recalibrate. The way clinicians do that is graded exposure.
In chronic pain, the protective system has often become more sensitive than the tissue actually needs.
04 · Graded movement and pacing
Chronic pain management in practice: graded movement and pacing
Graded exposure means starting at a level of activity that does not stir up much pain. You hold there until it feels comfortable, then build up in small steps. The point is to give the nervous system repeated, gentle experiences of safe movement, so the protective threshold can ease back towards what the tissue can actually handle. The work stays just below the pain rather than pushing through it.
Pacing is the partner to graded exposure. Many people living with chronic pain fall into a boom-and-bust cycle: on good days they do as much as possible to catch up, and the flare-up that follows leaves them doing very little for days. Pacing means setting a daily or weekly level of activity that is sustainable regardless of how the day feels, and building from that baseline rather than from the good days.
What this looks like in practice:
- An Exercise Physiologist can build a graded exercise program that respects flare-ups and progresses at a pace the body can adapt to.
- A Physiotherapist can assess movement, address mechanical contributors to pain, and work alongside Exercise Physiology on a combined plan.
- An Occupational Therapist can support pacing in real life, including work tasks, daily routines, and energy management.
The shared principle across these disciplines is consistency at a sustainable level, not intensity on a single day.
05 · What support looks like
What chronic pain support involves, and what the evidence shows
There is no single intervention that removes chronic pain completely. The most effective approach is multimodal: several elements running in parallel, adjusted over time, supported by a team that can include allied health, a GP, and, where appropriate, other consultants.
A typical plan can include:
- Graded exercise. Aerobic, strengthening, and gentle movement, built up slowly.
- Pain education. Understanding why pain persists, and how the protective system works, changes how people respond to pain signals.
- Pacing. Spreading activity across the day or week to break the boom-and-bust cycle.
- Sleep support. Sleep disturbance both worsens pain and is worsened by pain.
- GP-led medication review. Some medications have a role in chronic pain. That is a GP decision, not an allied health one.
- Psychological support (external). Optimum Health Solutions does not provide Psychology. A Psychologist, referred through your GP, can help with the mood, fear-of-movement, and stress side of pain that the biopsychosocial framework recognises as part of the picture.
It is worth being honest about the evidence on exercise. It is the most studied of the non-drug approaches, and Australian and international guidelines recommend it. The research shows it can reduce pain and improve function, though across chronic-pain conditions the effects are often modest and the quality of the studies still varies. What is clear is that exercise is safe, with side effects rarely worse than some temporary soreness that settles. For chronic low back pain specifically, the evidence is stronger, with good-quality reviews finding exercise is probably effective for reducing pain.
If you are unsure where to start, a GP appointment is usually the right first step. A GP can confirm or work up the diagnosis, rule out other conditions, and refer to allied health where appropriate.
