Spasticity is a functionally limiting disorder that commonly occurs following stroke or severe brain injury, and may lead to disability and pain. In tandem with neurorehabilitation, botulinum toxin type A (BoNT-A) is the recommended first-line treatment for spasticity and, to date, the majority of trials have reported BoNT-A use in patients >6 months after ictus. The present meta-analysis aimed to evaluate the effects of early BoNT-A injection for post-stroke spasticity on improvements in hypertonicity, disability, function and associated pain. A literature search yielded six studies reporting the effects of BoNT-A treatment within 3 months post-stroke; three in the upper limb and three in the lower limb. All six studies permitted concomitant rehabilitation. Reduction in hyper-tonicity was compared in all six studies and revealed a significant treatment effect (P = 0.0002) on the most affected joints between weeks 4 and 12 following injection. However, no significant effects of treatment were observed for improvement in disability at week 4 or improvement in function at weeks 4 and 20-24. A trend towards reduction in spasticity-related pain at week 4 following BoNT-A treatment (P = 0.13) was also observed. These results demonstrate the beneficial effects of BoNT-A treatment on improving hypertonicity within 3 months post-stroke and emphasise the importance of concomitant neurorehabilitation therapy.
