Māori aspirations following stroke: A pathway forward for the speech-language therapy field

Background: Attempts to improve Indigenous health outcomes are evident in the speech-language therapy (SLT) field, although they are restricted by a limited evidence base. Prior research has shown that SLT services do not always meet Indigenous stroke survivors’ needs, however, few studies have investigated this phe- nomenon and fewer have explored solutions. Consequently, the SLT field lacks knowledge of appropriate and optimal supports. Aims: To identify and compare experiences and aspirations of Māori stroke survivors, whānau (family), and speech-language therapists (SLTs) in Aotearoa New Zealand regarding SLT service provision. Methods & Procedures: Kaupapa Māori research and interpretive description methodologies underpinned this study. Four Māori stroke survivors, two whānau members, and five SLTs participated in semi-structured interviews. Data were analysed using constant comparative analysis and collaboratively interpreted during a hui (meeting) between researchers and participants. Outcomes & Results: Analysis highlighted six themes spanning experiences and aspirations: (1) tautoko (support), (2) kaupapa Māori (Māori approach), (3) whanaungatanga (relationships), (4) tino rangatiratanga (autonomy), (5) taiao (environment), and (6) kōnekeneke (change). Positive aspects of SLT were described, how- ever, Māori often did not receive optimal supports. Aspirations centred on changes to SLT services and the wider healthcare system. Conclusions: Adaptations to SLT services are indicated to improve the quality of SLT received by Māori following stroke. To meet aspirations described in this study, the SLT profession may incorpo- rate Māori approaches; prioritise strong, collaborative relationships; offer more autonomy to Māori stroke survivors; support the devel- opment of SLTs and SLT students; increase public awareness; and encourage change in the wider healthcare system. Many aspirations identified in the current study are consistent with those identified by Indigenous people in Australia, suggesting that some common solutions may exist to improving Indigenous SLT services

Diffusion tensor imaging and resting-state functional MRI-scanning in 5- and 6-year-old children: Training protocol and motion assessment

Advanced Magnetic Resonance Imaging (MRI) techniques such as Diffusion Tensor Imaging (DTI) and resting-state functional MRI (rfMRI) are widely used to study structural and functional neural connectivity. However, as these techniques are highly sensitive to motion artifacts and require a considerable amount of time for image acquisition, successful acquisition of these images can be challenging to complete with certain populations. This is especially true for young children. This paper describes a new approach termed the 'submarine protocol', designed to prepare 5- and 6-year-old children for advanced MRI scanning. The submarine protocol aims to ensure that successful scans can be acquired in a time- and resource-efficient manner, without the need for sedation. This manuscript outlines the protocol and details its outcomes, as measured through the number of children who completed the scanning procedure and analysis of the degree of motion present in the acquired images. Seventy-six children aged between 5.8 and 6.9 years were trained using the submarine protocol and subsequently underwent DTI and rfMRI scanning. After completing the submarine protocol, 75 of the 76 children (99%) completed their DTI-scan and 72 children (95%) completed the full 35-minute scan session. Results of diffusion data, acquired in 75 children, showed that the motion in 60 of the scans (80%) did not exceed the threshold for excessive motion. In the rfMRI scans, this was the case for 62 of the 71 scans (87%). When placed in the context of previous studies, the motion data of the 5- and 6-year-old children reported here were as good as, or better than those previously reported for groups of older children (i.e., 8-year-olds). Overall, this study shows that the submarine protocol can be used successfully to acquire DTI and rfMRI scans in 5 and 6-year-old children, without the need for sedation or lengthy training procedures. © 2014 Theys et al

A crucial role for the cortico-striato-cortical loop in the pathogenesis of stroke-related neurogenic stuttering

Neurogenic stuttering is an acquired speech disorder characterized by the occurrence of stuttering-like dysfluencies following brain damage. Because the onset of stuttering in these patients is associated with brain lesions, this condition provides a unique opportunity to study the neural processes underlying speech dysfluencies. Lesion localizations of 20 stroke subjects with neurogenic stuttering and 17 control subjects were compared using voxel-based lesion symptom mapping. The results showed nine left-hemisphere areas associated with the presen ce of neurogenic stuttering. These areas were largely overlapping with the cortico-basal ganglia-cortical network comprising the inferior frontal cortex, superior temporal cortex, intraparietal cortex, basal ganglia, and their white matter interconnections through the superior longitudinal fasciculus and internal capsule. These results indicated that stroke-induced neurogenic stuttering is not associated with neural dysfunction in one specific brain area but can occur following one or more lesion throughout the cortico-basal ganglia-cortical network. It is suggested that the onset of neurogenic stuttering in stroke subjects results from a disintegration of neural functions necessary for fluent speech. © 2012 Wiley Periodicals, Inc

Brain activation during non-habitual speech production: Revisiting the effects of simulated disfluencies in fluent speakers

Over the past decades, brain imaging studies in fluently speaking participants have greatly advanced our knowledge of the brain areas involved in speech production. In addition, complementary information has been provided by investigations of brain activation patterns associated with disordered speech. In the present study we specifically aimed to revisit and expand an earlier study by De Nil and colleagues, by investigating the effects of simulating disfluencies on the brain activation patterns of fluent speakers during overt and covert speech production. In contrast to the De Nil et al. study, the current findings show that the production of voluntary, self-generated disfluencies by fluent speakers resulted in increased recruitment and activation of brain areas involved in speech production. These areas show substantial overlap with the neural networks involved in motor sequence learning in general, and learning of speech production, in particular. The implications of these findings for the interpretation of brain imaging studies on disordered and non-habitual speech production are discussed
