Abstract

High prevalence and pervasiveness of cognitive deficits post-stroke have been identified in recent research (Mellon et al., 2015; Jokinen et al., 2015). These deficits impact not only independence in daily living, but also impact therapeutic outcomes. Traditional cognitive-linguistic therapy approaches explicitly address restoration of linguistic components but do not explicitly address cognitive deficits, such as auditory attention, that are frequently observed post-stroke. With rates up to 46-92%, attention has been identified as the most prominent stroke-related cognitive/neuropsychological change reported in acute stroke survivors (Barker-Collo et al., 2009). Limited evidence of the effect of auditory processing training on cognitive linguistic skills exists. Constraint Induced Auditory Training (CIAT) is a dichotic listening auditory training program that has garnered attention for use with PWAs in recent years (Hurley & Davis, 2011). Preliminary studies of PWAs have shown positive outcomes after CIAT, including auditory processing abilities, increased neural activity in auditory processing pathways, perceptual improvements, and increased participation in activities of daily living (Hurley & Davis, 2011). Currently, there are very few studies that investigate the combined effects of a cognitive-linguistic therapy (such as Treatment of Underlying Forms [TUF]) and auditory processing training (such as CIAT) on overall language abilities. This study was conducted to examine treatment and overall language outcomes of TUF used in combination with CIAT in a PWA with moderate aphasia.
