Perceptual analysis of speech following traumatic brain injury in childhood

Abstract

The results of the perceptual analysis are discussed in terms of the possible underlying pathophysiological bases of the deviant speech features identified, and the need for a comprehensive instrumental assessment, to more accurately determine the level of breakdown in the speech production mechanism in children following TBI.

Incidence and clinical presentation of dysarthria and dysphagia in the acute setting following paediatric traumatic brain injury

“…Deficits in prosody were most frequently reported. This is in contrast to the findings of Cahill and colleagues (2002) who reported that hypernasality was the predominant feature in children at least 6 months post TBI. It is possible that prosodic deficits such as reduced volume may resolve during the first 6 months post injury whereby hypernasality becomes more apparent signalling potential differences in the clinical presentation of speech in the acute versus rehabilitation setting.…”

“…Overall our dysarthria were largely consistent with previous studies of dysarthria in children with TBI from 6 months to 9 years post injury (Daniel‐Whitney 1989; Theodoros et al. 1998; Cahill et al. 2000, 2001a; Murdoch & Goozée 2003; Cheng et al.…”

“…1997; Theodoros et al. 1998; Cahill et al. 2000, 2001b, 2002, 2003, 2005; Murdoch & Goozée 2003; Cheng et al.…”

EMA analysis of tongue function in children with dysarthria following traumatic brain injury

“…Articulatory disturbances have been found to be common in dysarthria following TBI in both adults and children [1][2][3] and are recognized as having the potential to drastically affect intelligibility, even more so than other sub-system dysfunctions [4]. In order to effectively treat articulatory disturbances, it is imperative that the nature and severity of the underlying articulatory impairments first be determined, so that specific treatment methods can be employed to directly target those impairments [5].…”

Pediatric traumatic brain injury: Language outcomes and their relationship to the arcuate fasciculus

“…It can result from a combination of respiratory, phonatory, articulatory, and/or resonatory impairments (Cahill, Murdoch, & Theodoros, 2002). Although distinct functions, language deficits and dysarthria can both result following pediatric TBI, with reported co-morbidity rates being as high as 55% (Morgan et al, 2010).…”
