Effectiveness and optimal dosage of exercise training for chronic non-specific neck pain: A systematic review with a narrative synthesis.

Clinical guidelines for chronic non-specific neck pain are vague about which exercise approaches and doses actually help, so this systematic review set out to pull together what randomised trials have tested. The researchers searched widely and found 26 trials, involving over 2,000 participants in total, examining fifteen different exercise programmes, but the studies were too different from each other to combine statistically, so the findings are presented as a narrative synthesis rather than a pooled result. Overall, various exercise programmes appeared to ease pain and disability in the short term, with the strongest short-term results seen for programmes combining motor control exercises with segmental exercises. Pillar exercises showed benefit over a somewhat longer timeframe, though based on weaker evidence.

The main limitation is that most trials had a high risk of bias and small sample sizes, and no well-designed trials looked at long-term outcomes, so how these exercises perform beyond the short term remains unknown.

If you live with ongoing neck pain that isn't linked to a specific injury or disease, you may wonder which kind of exercise is actually worth your time. This review gathered 26 clinical trials testing fifteen different exercise programmes for chronic neck pain and tried to work out what the evidence actually shows. The short answer is that several different types of exercise seemed to help with pain and disability, at least in the short term, though the quality of evidence behind this was generally low to moderate.

Programmes combining motor control exercises, which focus on retraining how muscles coordinate movement, with segmental exercises targeting specific neck segments showed the most promising short-term pain reduction. Exercises for the body's core and trunk stabilising muscles seemed to help over a somewhat longer stretch of time. Importantly, no well-designed study has looked at what happens in the long run, and many of the included trials were small and carried a meaningful risk of bias.

This means the findings offer a helpful starting point but not firm, long-term answers.

This review addresses a genuine clinical gap: guidelines recommend exercise for chronic non-specific neck pain but give little direction on which type or dose to use. Drawing on 26 randomised controlled trials (n=2,288) testing fifteen distinct exercise programmes, the authors could not pool results statistically due to clinical heterogeneity, so findings rest on narrative synthesis rather than meta-analysis, which itself limits the strength of any conclusion. The synthesis suggests that a range of exercise approaches reduce pain and disability in the short term, with low to moderate quality evidence, and that programmes combining motor control exercise with segmental exercise showed moderate to very large pain reductions, though again rated low to moderate quality.

Pillar exercise showed intermediate-term benefit based on low-level evidence only. Increased frequency of motor control exercise and progressively loaded pillar exercise were associated with possibly improved effectiveness, but these are exploratory observations rather than established dosage parameters.

Critically, high risk of bias and small samples across trials reduce confidence in all effect estimates, and no high-quality trial examined long-term outcomes, meaning the optimal exercise type and dosage for sustained benefit remains undetermined.
