Original Article Residual Motor Control and Cortical Representations of Function Following Hemispherectomy: Effects of Etiology Stella de Bode, PhD; Ann Firestine, MS; Gary W. Mathern, MD; Bruce Dobkin, MD ABSTRACT Fifteen posthemispherectomy children were examined to assess residual motor function of the paretic side using the 74-point Fugl-Meyer Assessment of Motor Recovery scale. The degree of residual motor control differed for upper and lower extremities, with hand function being most severely impaired. Posthemispherectomy motor outcomes also differed as a function of etiology: cortical dysplasia, perinatal infarct, and Rasmussen’ s encephalitis. Children whose intractable seizures resulted from perinatal middle cerebral artery stroke demonstrated the most spared motor function. To detect
