Why exercise is 'the baseline treatment' in persistent pain
In persistent pain, the common error is seeking 'the technique that removes pain' without building capacity. Exercise is not merely 'strengthening': it acts on sensitivity, effort tolerance, sleep, mood, fear of movement (kinesiophobia) and social participation. The best contemporary evidence concludes that most non-surgical treatments produce modest effects, but exercise consistently emerges as one of the options with the best benefit-risk balance, particularly in chronic low back pain.
For families: if your relative has chronic pain, exercise is one of the most helpful tools. You don't need to be an athlete — starting gently and progressing slowly is key. This guide explains how to do it properly and safely.
Key concepts
Chronic pain: pain that persists or recurs beyond the expected healing time (typically >3 months). It may be secondary to disease/injury or primary (when pain and its impact are disproportionate to tissue damage). Therapeutic exercise: structured prescription (type-dose-progression) to improve function, effort tolerance and quality of life, and reduce pain and interference. NICE NG193 recommends offering supervised exercise programmes (often group-based) as part of chronic primary pain management.
For families: chronic pain is pain lasting more than 3 months. Therapeutic exercise is not 'doing sport' — it is a plan adapted to each person to improve gradually.
What the evidence says (2023–2026) by common conditions
- Chronic non-specific low back pain (CLBP): Cochrane 2023 (Network Meta-Analysis): evaluated multiple exercise types for CLBP and confirms that exercise, collectively, is an effective intervention (though with uncertainty regarding which modality consistently 'wins'). Clinical implication: there is no universal 'magic exercise'. The strongest outcome predictors are adherence + progressive dosing + functional approach.
- Knee osteoarthritis (OA): BMJ 2025 (NMA): in knee osteoarthritis, aerobic exercise emerged as a particularly beneficial modality for pain and function. Well-dosed aerobic exercise is not merely 'cardio' — it provides analgesia + functional improvement + weight management.
- Fibromyalgia (nociplastic pain): A 2025 NMA identified aquatic exercise as highly effective for short-term pain reduction and resistance training as particularly beneficial long-term (in women with fibromyalgia). Implication: in fibromyalgia, a programme combining tolerance (aerobic/aquatic) + capacity (resistance) with gradual progression avoiding symptom 'spikes' tends to perform best.
- Chronic musculoskeletal pain (global perspective): A 2025 umbrella review aggregating hundreds of reviews concluded that most have low or critically low methodological quality, yet the body of evidence supports exercise as a treatment pillar, with the caveat that the 'optimal prescription' per condition remains incompletely defined.
Exercise type selection by pain phenotype
- Chronic low back pain (CLBP): Combined (mixed): general resistance + motor control + mild-to-moderate aerobic. If movement fear is present: graded exposure (incrementally increasing activity without catastrophising symptoms).
- Osteoarthritis (knee/hip): Aerobic (walking/cycling/aquatic) + resistance (quadriceps/gluteal/calf) + balance. Criterion: tolerable pain (traffic light rule) + slow progression.
- Fibromyalgia: Entry: aquatic or gentle walking (for tolerance) + very progressive resistance training (for capacity).
- Pain with emotional comorbidity (anxiety/depression): Prioritise modalities with high adherence: walking + brief resistance training + (if appropriate) yoga/mind-body. Objective: improve sleep, energy and self-efficacy (rather than 'eliminating pain today').
Clinical dosing: 8–10 week programme for persistent pain
This is not a rigid prescription: it is a framework that functions across most profiles when individualised.
Clinical safety: symptom traffic light and red flags
Refer or assess first if present: fever, unexplained weight loss, progressive night pain, progressive neurological deficit, significant trauma, suspicion of infection/tumour/fracture.
For families: there is a simple 'traffic light' system to know if exercise is going well (green = continue, amber = slow down, red = stop and consult). It is very important to know the warning signs that require urgent medical attention.
