    • Inter-joint coordination analysis of reach-to-grasp kinematics in children and adolescents with obstetrical brachial plexus palsy

      Published in Clin Biomech. This project was a study of the way children with neural injury near the shoulder reach differently from typically developing children. The analytical method used was developed by Dr. Kukke originally in a different patient population and is applied here to study reaching after brachial plexus palsy.

    • Hearing Safety From Single- and Double-Pulse Transcranial Magnetic Stimulation in Children and Young Adults

      Published in the Journal of Clinical Neurophysiology. Transcranial magnetic stimulation (TMS) is a method by which brain tissue can be stimulated briefly and non-invasively to study neural function. In this study, we observe the effect of TMS on hearing because the stimuli are loud and applied near the ear. Results indicate single and double pulses of TMS do not affect hearing in children and young adults who are wearing hearing protection.

    • Neurophysiological features of tactile versus visual guidance of ongoing movement

      Published in Experimental Brain Research. Hand movements are guided by sensory information, but different modalities of sensation are processed differently. This project explored neural correlates of tactile versus visual guidance of hand movements using electroencephalography in healthy adults and identified brain regions that are activated in both conditions, and others that are activated either for touch or vision.

    • Coordination of Reach-to-Grasp Kinematics in Individuals With Childhood-Onset Dystonia Due to Hemiplegic Cerebral Palsy

      Published in IEEE Transactions on Nueral Systems and Rehabilitation Engineering. In this study, we characterized differences in the way children and young adults with a motor disorder, dystonia, reach to grasp objects compared to typically developing individuals. A novel analytical method is presented in which a typical time-varying pattern of multiple joints is observed in the typically developing group as a reference to study deficits of joint coordination in the patient group.
