Summary

This study looked at 40 stroke patients with arm muscle stiffness (spasticity) who were treated with botulinum toxin (Botox). Researchers measured tiny electrical signals in the muscle to see how they change over time and whether they can predict when the treatment effect wears off. The goal was to better understand how the treatment works and find a signal threshold that indicates the effect is decreasing.
