This study will monitor patients during the first year following their stroke.

Stroke is a very serious condition where there is a sudden interruption of blood flow in the brain.

The main aim of the study will be to find out how many of those who experience their first-ever stroke then go on to develop spasticity that would benefit from treatment with medication.

Spasticity is a common post-stroke condition that causes stiff or ridged muscles.

The results of this study will provide a standard guideline on the best way to monitor the development of post-stroke spasticity.

Official Title

A Prospective, Multicountry Study to Estimate the Incidence of and Provide a Best Practice Model for Monitoring the Development of Post-Stroke Spasticity
