After completing his neurology residency at the University of Iowa, Francis O. Walker, MD, completed a fellowship in Movement Disorders with Anne Young, MD, PhD, at the University of Michigan. He joined the faculty at Wake Forest School of Medicine in 1984 and began the movement disorders service.
With a grant from the Hereditary Disease Foundation, Dr. Walker conducted the first therapeutic clinical trial in Huntington’s disease in the state of North Carolina and since has conducted over 20 studies in this disorder. Beginning in 1989, he began pioneering the optimal use of EMG needle guidance for therapeutic botulinum toxin injections in patients with dystonia. Working with Dr. Tatter he helped initiate the Parkinson’s surgery program, which was subsequently formalized by Drs. Siddiqui, Haq and Ellis. Currently Dr. Walker is a member of the Huntington’s and Parkinson’s study group and an active investigator and collaborator in both fields.
Allison Brashear, MD, is Professor and Chair of the Department of Neurology. Dr. Brashear has a special interest in cervical dystonia and spasticity. She has been the principal investigator in many multi-center trials in the treatment of cervical dystonia and spasticity with botulinum toxin. She was the lead author on the pivotal paper, “Intramuscular Injection of Botulinum Toxin for the Treatment of Wrist and Finger Spasticity After a Stroke”, published in The New England Journal of Medicine in 2002.
She is the Chair of the American Academy of Neurology (AAN) Spasticity/Dystonia Advisory Board. She is the vice-chair of the Unified Council of Neurologic Subspecialties (UCNS). Dr. Brashear is the principal clinician to describe a unique genetic form of dystonia-parkinsonism, Rapid-Onset Dystonia-Parkinsonism (RDP) which was reported in Neuron and Brain.
