P06-Cortical somatosensory processing after botulinum toxin therapy in post-stroke spasticity

In movement disorders, neurophysiology and functional MRI demonstrated abnormalities of sensorimotor processing, responding to peripheral botulinum toxin A (BoNT) treatment. We used Modified Ashworth scale (MAS) to assess spasticity and median nerve somatosensory evoked potentials (SEP) to study changes in sensorimotor cortical areas after BoNT therapy of post-stroke arm spasticity.Seventeen patients (10 men, 7 women, average age 60.2 years) with post-stroke arm spasticity were treated with BoNT into the affected muscles.
