This review examines central sensitisation, a state in which the nervous system itself becomes more sensitive to pain signals, and summarises current understanding of how it appears across chronic pain conditions including spinal pain, fibromyalgia and arthritis.
What was studied?
The review covered evidence on central sensitisation across fibromyalgia, osteoarthritis, rheumatoid arthritis, tendon problems, headache and spinal pain, examining how much it varies between individuals with the same diagnosis.
What did they find?
Central sensitisation appears to varying degrees across all conditions studied, and its presence is linked to poorer outcomes from standard treatment. Both medication and non-drug treatments, including exercise and pain education, help reduce it.
Why it matters
Two people with what looks like the same injury or diagnosis can experience very different levels of pain. Treatment sometimes needs to address the sensitivity of the nervous system itself, not only the original site of injury.
Why we included it
It shows why assessment needs to look beyond a single structural cause, since a shared nervous system process can shape presentation across very different conditions.
