Is an extra 3° worth it? 🤔
I shared this paper a year ago, and revisited it in much greater detail while developing my serial casting course.
This systematic review raises questions about how much adding Botox actually contributes to serial casting outcomes for children with cerebral palsy.
The additional gain in passive ankle dorsiflexion? Around 3°. The authors questioned how clinically meaningful that difference was and when one study was removed in a sensitivity analysis, the difference was no longer statistically significant.
The review also shared that in one study, spasticity returned and increased faster in the botox and casting group than the casting group only.
So, is that potential extra range worth the trade-off, particularly when questions remain about long-term effects?
Three degrees might matter for an individual child. But we need to ask what it changes for their movement, function and goals and weigh that against the potential risks.
I’ve shared other posts about Botox’s potential adverse effects on my page.
Follow along if you’re keen to question familiar practices and look more closely at the evidence behind them.
