Effects of Botulinum Neurotoxin Type A (BoNT/A) Free of Complexing Proteins in the Spastic Equinovarus Foot

Summary

Clinical randomized clinical trial to assess the effectiveness on walking speed of repeated use of botulinum neurotoxin type A (BoNT/A)in the post-stroke spastic equinovarus foot in three successive infiltrations at 6-month intervals, checking if the sustainability of the effect is greater in incobotulinumtoxin A (Xeomin®) than in onabotulinumtoxinA (Botox®).
