This study aims to evaluate, in hemiparetic patients, changes in muscle ultrasound structure about the focal treatment of spasticity with botulinum toxin type A. For this purpose, the analysis of the mean echo intensity will be carried out on ultrasound acquisitions, identifying the possible correlations between the muscle echogenicity, the variations in the pennation angle, and the length of the fascicles. For image processing operations, ImageJ software was applied.

RECRUITINGmuscle structure variations
The primary outcome consists in detecting muscle structure variations during the procedure. This measure will be related to the time frame between the first inoculation and the moment of image acquisition, and to the number of therapeutic cycles performed. The aim is to determine the potential correlation between BoNT-A injection and muscle structure evolution. The time point of assessment is not pre-defined but the time since stroke onset and, if applicable, from the first BoNT-A injection will be recorded. Each participant will be assessed once during the overall duration of the study.
Time frame: single measure through study completion (1 year)
