The effectiveness of physiotherapy for patients with isolated cervical dystonia: an updated systematic review and meta-analysis.

Cervical dystonia, a movement disorder causing twisting neck postures and muscle contractions, is commonly treated with botulinum toxin injections, but whether adding physiotherapy improves outcomes has been unclear. This review brought together fourteen interventional studies on physiotherapy for isolated cervical dystonia, with two of them pooled into a meta-analysis focused on pain. The pooled result showed physiotherapy added to botulinum toxin injection led to a significant reduction in pain compared with botulinum toxin alone. The broader set of studies also pointed toward possible benefits for disease severity, disability, and quality of life, though the evidence here is less certain.

A key limitation is that the physiotherapy programs varied widely in type and duration, and only two studies contributed to the main pooled pain result, so the overall evidence base remains small and the authors could not recommend a specific physiotherapy approach.

If you live with cervical dystonia, the involuntary neck twisting and muscle contractions that come with it, you may already know that botulinum toxin injections are a common treatment. This review looked at whether adding physiotherapy on top of those injections makes a difference, pulling together findings from fourteen studies on physiotherapy for this condition. The main finding, based on two pooled studies, is that physiotherapy added to botulinum toxin injections was linked to a meaningful reduction in pain compared with botulinum toxin alone.

The wider body of research also hinted that physiotherapy might help with disease severity, daily disability, and quality of life, though these signals are less certain than the pain finding. It's worth knowing that the physiotherapy programs studied differed a lot in what they involved and how long they lasted, and the strongest result rests on just two studies. That means while the pain finding is encouraging, the overall evidence is still limited, and no single physiotherapy approach stood out as the one to prefer.

This review addresses a practical question many physiotherapists treating cervical dystonia face: does adding physiotherapy to standard botulinum toxin injection therapy meaningfully change patient outcomes, and if so, which outcomes and which approach? Fourteen interventional studies were included in the narrative review, with two contributing to a meta-analysis on pain. The pooled estimate found a statistically significant reduction in pain (mean difference -5.00, 95% CI -6.26 to -3.74) when physiotherapy was added to botulinum toxin injection, compared with injection alone. This informs the specific question of whether physiotherapy has an additive role alongside standard pharmacological treatment, rather than establishing physiotherapy as a standalone intervention.

The broader review also suggested possible benefits for disease severity, disability, and quality of life across the full set of fourteen studies, but these are described only as possible effects, not confirmed ones, and should be read with less confidence than the pain result. The central limitation for applying this is the small number of studies behind the pooled pain estimate and the marked heterogeneity in physiotherapy type and duration across the broader literature, which prevented the authors from recommending any specific physiotherapy protocol or dosage. The abstract does not report on adverse events or risk-of-bias ratings for individual studies beyond noting that checklists were used.
