About

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.
