NCT05615987

Brief Summary

The aim of the study is to compare the effectiveness of the classical (2-4 points to the muscle proximal) application of botulinum toxin in the treatment of spasticity with the application along the length of the gastrecnemius muscle. The main question it aims to answer Is botulinum toxin more effective in the treatment of spasticity than the classical application applied along the length of the gastrocnemius muscle? Participants will be evaluated for spasticity before and 1 month after injection. Researchers will compare classical versus application along the length of the muscle to see if there is a reduction in spasticity.
