Tiny muscle signals could predict botox success in stroke survivors

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 relate to how well the treatment works. The goal was to better understand how Botox affects nerve-muscle communication and possibly find a way to predict when the effect starts to wear off.
