Botulinum toxin therapy as early intervention in post-stroke upper limb spasticity

Pooled systematic studies that compare treatment stragegies for post-stroke spasticity prove that Botulinum toxin-A (BoNT-A) has superior efficacy and safety and has become the first line management in tandem with physiotherapy. The natural evolution of spasticity show that, not only are neural mechanisms of muscle hypertonus come into play, but that biomechanical forces may likely set in 3 months after stroke. Uses of BoNT-A have been driven by pre-defined goals in the established stage of spasticity (i.E. > 6 months from onset of stroke), as well as the practice of repeat cycle injections to reduce muscle tone. About 19-33% of patients develop spasticity within 3 months after the ictus. Early intervention with BoNT-A (i.e.
