To identify important treatment outcomes from the perspective of people with aphasia and their families using ICF as a frame reference.The nominal group technique was used family members in seven countries to rank rehabilitation. People identified for themselves; themselves person aphasia. Outcomes were analysed qualitative content analysis linking.A total 39 29 participated one 16 groups. Inductive revealed following six themes: (1) Improved communication; (2) Increased life participation;...
The 1st aim of this study was to further establish the external validity main concept (MC) analysis by examining its relationship with Cantonese Linguistic Communication Measure (CLCM; Kong, 2006; Kong & Law, 2004)-an established quantitative system for narrative production-and version Western Aphasia Battery (CAB; Yiu, 1992). 2nd purpose evaluate how well MC reflects stability discourse production among chronic speakers aphasia.Sixteen participants aphasia were evaluated on analysis, CAB,...
This paper revisits the Age of Acquisition (AoA) norms Kuperman et al. (2012). Three studies were conducted. Study 1 reports a crowdsourcing 'megastudy' obtaining 790,024 estimates from participants providing age they could first read and write 11,074 early acquired words The study aimed to differentiate between oral language receptive AoA print AoA. results correlate well with original offer slightly higher values for knowledge. They are released as useful supplements norms. 2 explored...

Neuroimaging studies suggest that the neural network involved in language control may not be specific to bi-/multilingualism but is part of a domain-general executive system. We report trilingual case Cantonese (L1), English (L2), and Mandarin (L3) speaker, Dr. T, who sustained brain injury at age 77 causing lesions left frontal lobe temporo-parietal areas resulting fluent aphasia. T's functions were impaired according modified version Stroop color-word test Wisconsin Card Sorting Test...
This paper describes the application of state-of-the-art automatic speech recognition (ASR) systems to objective assessment voice and disorders. Acoustical analysis has long been considered a promising approach non-invasive people. In past types amount materials used for acoustical were very limited. With ASR technology, we are able perform linguistic analyses with large natural from impaired speakers. The present study is focused on Cantonese, which major Chinese dialect. Two representative...
ABSTRACTABSTRACTThis study reports the validation of Hong Kong version Oxford Cognitive Screen (HK-OCS). Seventy Cantonese-speaking healthy individuals participated to establish normative data and 46 chronic stroke survivors were assessed using HK-OCS, Albert’s Test Visual Neglect, short test gestural production, following assessments: Western Aphasia Battery, MMSE, MoCA, Modified Barthel Index, Lawton Instrumental Activities Daily Living scale. The validity HK-OCS was appraised by...
Purpose. Discourse from speakers with dementia and aphasia is associated comparable but not identical deficits, necessitating appropriate methods to differentiate them. The current study aims validate the Main Concept Analysis (MCA) be used for eliciting quantifying discourse among native typical English establish its norm, investigate validity sensitivity of MCA compare produced by individuals fluent aphasia, non-fluent or Alzheimer's type (DAT), unimpaired elderly. Method. elicited through...
Purpose Enhancing social participation and reducing emotional distress in persons with aphasia (PWA) are a critical rehabilitation goal. Social relationships meaningful activities performed by PWA also crucial to promote positive psychosocial well-being. As precautionary measure specific the COVID-19 pandemic, most worldwide have generally followed guidelines of going out less, restricting when where gather friends peers, activities, maintaining appropriate distance; these acts contrary...
Purpose. This study investigates (a) the provision of speech-language pathology (SLP) services and community resources in Hong Kong for persons with aphasia (PWA) their families (b) family members' perception service quality.Methods. A self-administered 42-item questionnaire was distributed two support groups. The questions included information on demography data PWAs, details SLP PWAs' satisfaction hospital-based groups.Results. Results from 37 completed questionnaires indicated most...
Aphasia is a common type of acquired language impairment resulting from dysfunction in specific brain regions. Analysis narrative spontaneous speech, e.g., story-telling, an essential component standardized clinical assessment on people with aphasia (PWA). Subjective by trained speech-language pathologists (SLP) have many limitations efficiency, effectiveness and practicality. This article describes fully automated system for speech Cantonese-speaking PWA. A deep neural network (DNN) based...
Health professionals, researchers, and policy makers often consider the two terms aphasia dysphasia to be synonymous. The aim of this article is argue merits exclusive use term present a strategy for creating change through institutions such as WHO-ICD. Our contention that one avoids confusion, speech-language pathologists prefer aphasia, scholarly publications indicate preference stroke clinical guidelines consumer organizations title in their name on websites, languages other than English...
Coverbal gesture use, which is affected by the presence and degree of aphasia, can be culturally specific. The purpose this study was to compare use among Cantonese-speaking individuals: 23 neurologically healthy speakers, speakers with fluent 21 nonfluent aphasia.Multimedia data discourse samples from these were extracted Cantonese AphasiaBank. Gestures independently annotated on their forms functions determine how gesturing rate distribution gestures differed across speaker groups. A...
AbstractThis paper describes the use of a Cantonese linguistic communication measure (CLCM) to quantify narrative production aphasic speakers. Four new pictures containing local characteristics were developed, including revised from BDAE (Goodglass and Kaplan, 1993), WAB (Kertesz, 1982) its version (Yiu, 1992), picture depicting Chinese restaurant. The development pictorial stimuli was motivated by lack culturally appropriate for eliciting speech CLCM contains eight indices reflecting...
