The Effects of Botulinum Toxin and Casting in Spastic Children With Cerebral Palsy: A Systematic Review and Meta-Analysis

Abstract

Cerebral palsy (CP) is a neurological disorder that affects muscle tone, movement, and motor skills in children. One of the most common symptoms of cerebral palsy is spasticity, which is characterised by involuntary muscle contractions and stiffness. Both botulinum toxin and casting have been used as standalone treatments for spasticity in cerebral palsy, but which is better is still unclear. The aim of the present meta-analysis was to compare the effects on spasticity of serial casting and/or botulinum toxin type A (BoNT-A) in conjunction with or as independent therapies. Studies up to February 2022 were identified in four separate databases. The inclusion criteria were randomised controlled trials (RCTs) that compared different therapies (Botulinum toxin A, or BoNT-A, and casting) and assessed spasticity improvement in children with spastic cerebral palsy who were younger than 18 years old and were published in English. With a 95% confidence interval (CI), the standardised mean difference (SMD) was utilised to calculate treatment effects. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist was followed to undertake the current study. The search for relevant literature in four databases generated 147 results. After the abstract and full-text screening, five publications with a total of 190 cerebral palsy patients were included in this systematic review and meta-analysis. In patients with cerebral palsy, both methods -botulinum toxin and casting-apply globally; our systematic review tries to find out the most effective treatment between the two but does not show any significant difference in these methods. As we know, botulinum toxin is expensive, and the casting method is time-consuming and poorly accepted by patients. There is a need for an excellent study to examine the impact of casting and botulinum toxin type A.
