Abstract
As the authors suggest, knowledge of functional differences between CVA patients with left hemisphere lesions (LHL) versus right hemisphere lesions (RHL) could help therapists develop more appropriate evaluation tools and guide their therapeutic emphasis. Enhanced understanding and realistic expectations can diminish the frustration so often inherent in a prolonged rehabilitation course. In this Commentary, I will discuss the methods used by Mills and DiGenio in their study, Functional Differences in Patients with Left or Right Cerebrovascular Accidents, and the general contribution of this study to clinical research. Also, I will make suggestions for further research and elaborate on factors of hemispheric specialization, particularly those associated with RHL that may be related to rehabilitation outcome. Assigning objective values to the rather subjective and multifaceted variables of the art of our profession often frustrates those conducting neurologically related clinical research. Retrospective chart reviews are frequently most vulnerable to such limitations.
