Spasticity vs Dystonia:
Spasticity is characterised by increase in muscle tone along with exaggeration of the stretch reflexes resulting in a “catch” when attempting a rapid passive stretch of the affected muscles.
Dystonia is characterised by an increased and variable tone that is not velocity dependant.
In Cerebral Palsy Botulinum toxin injections can be used for;
treatment of spasticity
