Post-stroke Spasticity

Keywords

Brief summary
The aim of the study was to analyze which step of the procedure of toxin botulinum injection is the most painful between skin break-in, electric stimulation, injection and needle withdrawal.
Detailed description
Post-stroke spasticity management by botulinum toxin injections may be limited by pain or discomfort at the injection side. Particularly tracking by electrostimulation, but also skin puncture, toxin injection or needle withdrawal may be painful. The objective of this study is to define an individual injection strategy in order to limit pain.
Interventions
OTHERpain rating during injection with botulinum toxin
The pain intensity was rated verbally on a numeric scale. The pain was rated after each phase of injection
