Four exercise styles ease neck pain disability

Nonspecific neck pain is one of the most common musculoskeletal complaints, and it frequently causes substantial functional disability and reduced quality of life. Exercise therapy sits at the centre of its management, yet patients and clinicians face a crowded menu of options, from stretching and strength work to mind-body practices. The comparative effectiveness of these specific modalities has remained unclear. It has also been uncertain whether the amount of exercise done in each session matters, and if so, how much is enough to see a benefit.

The researchers pooled 51 randomised controlled trials with 4,140 participants into a Bayesian random-effects network meta-analysis, a design that lets different exercise modalities be compared even when they were never tested head-to-head. Functional disability, assessed with validated instruments, was the primary outcome. Effects were summarised as standardised mean differences with 95% credible intervals. An exploratory dose-response analysis then examined how per-session exercise dose, expressed pragmatically as MET-min, related to disability outcomes.

Mind-body exercise showed the largest reduction in neck-pain-related functional disability versus control, with a standardised mean difference of -0.363. Resistance training (-0.359), flexibility training (-0.352) and coordination training (-0.328) were also associated with reductions, and the four estimates sat close together rather than one modality clearly dominating. The exploratory dose-response analysis suggested a possible non-linear pattern: estimated reductions appeared from around 100 MET-min per session, with larger study-level effects around 300-400 MET-min per session. The authors themselves flag that these dose findings should be read cautiously.

This work supports the established view that exercise is central to managing nonspecific neck pain, but it extends the evidence by directly ranking modalities against each other within one analysis. Earlier evidence left the comparative question open; here, several quite different approaches produced similar-sized benefits. The heterogeneity of the pooled interventions and the reliance on study-level rather than individual data mean the dose-response curve is a hypothesis, not a prescription. Which patients respond best to which modality, and over what timescale, remain open questions.

If neck pain limits what you can do day to day, this is a reason to think that structured movement of several kinds — mind-body work, resistance training, flexibility or coordination exercise — is associated with less disability. The similarity of effects across modalities suggests the best-supported option may simply be the one a person will actually keep doing. The finding that benefits appeared from a relatively modest per-session dose is encouraging but tentative. None of this replaces individual assessment for persistent pain.
