Active Research Projects

Movement Characterization in Cerebral Palsy
Through the integration of classical ballet exercises with virtual reality and haptic environments, this project aims to characteize movement in children with cerebral palsy. 
Targeted Ballet Class for Children  and Adults with Cerebral Palsy
Examining muscle regulation adaptations in response to classical ballet training in children a nd adults with cerebral palsy. 
Mindful Ballet Class for Adults with Multiple Sclerosis
A combination of mindfulness training and classical ballet targeted to adults diagnosed with multiple sclerosis seeks to improve gait function and balance while ameliorating ataxia..
