Pain During Injection With Botulinum Toxin in Post-stroke Spasticity Treatment

Completed
Conditions
Post-stroke Spasticity
Interventions
Other: pain rating during injection with botulinum toxin
Registration Number
NCT03251521
Lead Sponsor
University Hospital, Grenoble
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.
