    "Go aphasia!": Examining the efficacy of Constraint-Induced Language Therapy for individuals with agrammatic aphasia
    (2008-08-25) Virion, Christine; Faroqi-Shah, Yasmeen; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Recently, high intensity short-term therapy with a heavy emphasis on verbal language (called constraint induced language therapy, CILT) has gained momentum in aphasiology. However, the entire extent of its applicability and limitations has not been fully studied, especially with regard to specific aphasic deficits. This thesis sought to: 1) determine the efficacy of the originally published CILT protocol (o-CILT) with a deficit specific population (four individuals with agrammatic aphasia) and 2) examine the potential effect of a modified CILT protocol, which additionally focused on grammatical accuracy (g-CILT). Results revealed differences between the performance of individuals with agrammatism in this study and previously published CILT data. Findings also demonstrated that participants receiving g-CILT produced more significant gains on tests of aphasia severity and grammaticality, while individuals receiving o-CILT showed more highly significant changes on discourse measures of grammaticality. This paper suggests that, for individuals with agrammatism, CILT in its original form may not evince significant changes on tests of aphasia severity and grammatical production and a grammatical modification appears to increase the efficacy of CILT.

    A Voxel Based Approach to Identifying Lesion Sites in Aphasia: Comprehension and Production Deficits in Syntax, Semantics and Phonology
    (2007-08-20) Kling, Therese Danielle; Shah, Yasmeen; Braun, Allen; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The cortical regions of the brain traditionally associated with deficits of production and comprehension in language are Broca's and Wernicke's areas. Recent evidence suggests that other brain regions are involved and may be specific to linguistic areas of syntax, semantics and phonology. This paper describes the MRI results and language scores of 31 left hemisphere stroke patients with aphasia. Patients' lesions obtained from these MRI scans were reconstructed onto templates and entered into a voxel-based analysis program called Analysis of Brain lesion (ABLe) (Solomon, Raymont, Braun, Butman & Grafman, 2007) along with language scores. The results provided evidence for five key neuroanatomical regions of interest. These include the insula, the planum temporale, the operculum, the temporoparietal occipital (TPO) junction and the putamen. The results revealed common as well as unique areas of brain lesion for each of the behaviors.
