Dr. Juergen Konczak, Kinesiology professor in biomechanics,  and Dr. Stephanie Valberg, professor of veterinary population medicine in the University Equine Center, presented their recent data on uncovering the causes of the equine movement disorder, “shivers,” at the Department of Neurology’s  Grand Rounds on December 14. “Shivers” is an equine condition characterized by tremors and flexion of the hind limbs. Up to now, the etiology of the disease was not well understood. After mapping the abnormal patterns of muscle innervation and finding that they are associated with neurodegenrative processes within the cerebellum, Dr. Konczak and Dr. Valberg outlined, for the first time, the possible causes of the disease. Their presentation titled “From horses to humans: gait ataxia in the equine movement disorders ‘shivers'” can be streamed from the Department of Neurology’s video archive.
