RESUMO
OBJECTIVE: To determine the interrater reliability of the Scale for the Assessment and Rating of Ataxia (SARA), Berg Balance Scale (BBS), and motor domain of the FIM (m-FIM) administered by physiotherapists in individuals with a hereditary cerebellar ataxia (HCA). DESIGN: Participants were assessed by 1 of 4 physiotherapists. Assessments were video-recorded and the remaining 3 physiotherapists scored the scales for each participant. Raters were blinded to each other's scores. SETTING: Assessments were administered at 3 clinical locations in separate states in Australia. PARTICIPANTS: Twenty-one individuals (mean age=47.63 years; SD=18.42; 13 male and 8 female) living in the community with an HCA were recruited (N=21). MAIN OUTCOME MEASURES: Total and single-item scores of the SARA, BBS, and m-FIM were examined. The m-FIM was conducted by interview. RESULTS: Intraclass coefficients (2,1) for the total scores of the m-FIM (0.92; 95% confidence interval [CI], 0.85-0.96), SARA (0.92; 95% CI, 0.86-0.96), and BBS (0.99; 95% CI, 0.98-0.99) indicated excellent interrater reliability. However, there was inconsistent agreement with the individual items, with SARA item 5 (right side) and item 7 (both sides) demonstrating poor interrater reliability and items 1 and 2 demonstrating excellent reliability. CONCLUSIONS: The m-FIM (by interview), SARA, and BBS have excellent interrater reliability for use when assessing individuals with an HCA. Physiotherapists could be considered for administration of the SARA in clinical trials. However, further work is required to improve the agreement of the single-item scores and to examine the other psychometric properties of these scales.

YolÅu, Aboriginal people from Arnhem Land, Australia are at risk of Machado-Joseph disease, with progressive loss of speech. YolÅu are interested in developing augmentative and alternative communication (AAC) systems in their own languages. This research aimed to develop a culturally responsive process to explore and create a core vocabulary word list for YolÅu adults living with the disease for inclusion in AAC system prototypes. A list of 243 YolÅu words and morphemes was created. In this highly collaborative, mixed methods, participatory action research, Balanda (the YolÅu word for non-Aboriginal people) and YolÅu researchers conducted cycles of transcription and analysis of a language sample, with oral group discussions to identify which words to include, omit, or add, based on YolÅu perceptions of the structure and use of their languages. A YolÅu metaphor, Gulaka-buma ("Harvesting yams"), was identified by YolÅu researchers to represent and share the research process and findings. Three key themes were identified that summarize the main cultural and linguistic considerations related to changes made to the core vocabulary. Study findings emphasized the role of language as an expression of culture and identity for Indigenous peoples and the importance of considering cultural and linguistic factors in selecting vocabulary for AAC systems.

YolÅu (Aboriginal Australians of northeast Arnhem Land) are interested in developing augmentative and alternative communication (AAC) systems in their own languages to support communication opportunities and participation for their family members living with Machado-Joseph disease. Designing AAC systems in Aboriginal languages requires consideration of unique linguistic and cultural elements. Participatory action research in strength-based communication contexts was carried out by YolÅu and Balanda (the YolÅu word for non-Aboriginal people) researchers working together through a collaborative intercultural process. Culturally responsive literacy, language, and AAC activities were used to develop four prototype YolÅu AAC sytems for YolÅu with varied literacy skills. Data were coded using gerunds to identify and focus on action in the data. Reflective and analytical collaborative, oral group discussions were used to identify key considerations and, ultimately, a YolÅu metaphor for the research. YolÅu language, culture and worldview impacted all aspects of prototype design and decision making. Salient considerations related to representation, organization, layout, and access, are presented. Clinical implications and future research considerations are outlined.

BACKGROUND: Aboriginal and Torres Strait Islander people do not enjoy equal access to specialist health services that adequately meet their needs. Clinical genetics services are at the vanguard of realising the health benefits of genomic medicine. As the field continues to expand in clinical utility and implementation, it is critical that Aboriginal and Torres Strait Islander people are able to participate and benefit equally to avoid further widening of the existing health gap. This is the first study to explore barriers to accessing clinical genetics services among Aboriginal and Torres Strait Islander people, which has been acknowledged as a key strategic priority in Australian genomic health policy. METHODS: A participatory design process engaged a majority-Aboriginal Project Reference Group and Aboriginal End-User Group. 63 semi-structured interviews were conducted with Aboriginal and/or Torres Strait Islander people who had accessed the government-funded clinical genetics service in Western Australia, Queensland or the Northern Territory between 2014 and 2018. The sample included patients, parents and carers. Participants were asked to recount their 'patient journey', from referral through to post-appointment and reflect on their perceptions of genetics and its implications for the health of themselves and their families. Analysis tracked chronological service engagement, followed by an inductive thematic approach. RESULTS: Barriers to access and engagement were present at each stage of the patient journey. These included challenges in obtaining a referral, long waiting periods, limited genetic literacy, absence of Aboriginal support services, communication challenges and lack of adequate psychosocial support and follow-up after attendance. Participants' overall experiences of attending a genetic health service were varied, with positive perceptions tied closely to a diagnosis being achieved. The experience of (and expectation for) recognition of cultural identity and provision of culturally safe care was low among participants. Unaddressed concerns continued to cause significant distress in some people years after their appointment took place. CONCLUSIONS: There is significant scope for improving the care provided to Aboriginal and Torres Strait Islander people at clinical genetics services. Immediate attention to minimising logistical barriers, developing relationships with Aboriginal Community Controlled Health Services and providing practical and specific cultural safety training for practitioners is required at the service-level. Our findings strongly support the development of guidelines or policies recognising the collective cultural needs of Aboriginal and Torres Strait Islander people in relation to genomic health care.

BACKGROUND: Indigenous people tend to exhibit a higher burden of disability than their non-Indigenous counterparts, and are often underserved by disability services. Engaging appropriately with Indigenous communities, families and individuals in the initial stages of disability assessment and planning is crucial in order to build trust and understanding of disability service models and ensure that Indigenous people receive support that is tailored to their needs and cultural realities. This article aims to identify key elements of culturally competent communication in Indigenous disability assessment and planning, and provide recommendations for strengthening capacity in this area. METHODS: This qualitative research was designed to involve Aboriginal and Torres Strait Islander people at all stages and to reflect the views of Aboriginal and Torres Strait Islander researchers, people and families affected by disability and the community-controlled health sector. Semi-structured individual interviews were undertaken with staff implementing the National Disability Insurance Scheme (NDIS) (n = 4), NDIS participants (n = 24), disability support providers and organisational partners (n = 19) and Community Connectors (n = 8) in Queensland and the Northern Territory of Australia. Key themes derived from thematic analysis included appropriate and adequate engagement of individuals with disability and their families, the role of trusted relationships, and culturally safe and appropriate communication during planning meetings. RESULTS: Overall, the research findings highlight that a low level of cultural competence in the initial stages of the disability assessment and planning process exacerbated participant confusion and distrust towards assessment staff and the NDIS. Given difficulties in communication, participant understanding of the NDIS was generally limited. The necessity of culturally safe and appropriate use of interpreters was stressed, as was the role of trusted individuals, including existing service providers, Community Connectors and family members in providing a solid base for participant understanding of the NDIS. CONCLUSIONS: Cultural competence in disability assessment and planning can be strengthened through multi-level engagement with the Aboriginal community-controlled sector and community leaders. Implementing mechanisms to enable the involvement of families, trusted service providers and Community Connectors can support a more meaningful understanding of individuals' needs within their cultural context and in relation to their cultural roles.

Advances in our understanding of genetic and rare diseases are changing the face of healthcare. Crucially, the global community must implement these advances equitably to reduce health disparities, including between Indigenous and non-Indigenous peoples. We take an Australian perspective to illustrate some key areas that are fundamental to the equitable translation of new knowledge for the improved diagnosis of genetic and rare diseases for Indigenous people. Specifically, we focus on inequalities in access to clinical genetics services and the lack of genetic and phenomic reference data to inform diagnoses. We provide examples of ways in which these inequities are being addressed through Australian partnerships to support a harmonious and inclusive approach to ensure that benefits from traditional wisdom, community knowledge and shared experiences are interwoven to support and inform implementation of new knowledge from genomics and precision public health. This will serve to deliver benefits to all of our diverse citizens, including Indigenous populations.

Globally, there is a recognised need that all populations should be able to access the benefits of genomics and precision medicine. However, achieving this remains constrained by a paucity of data that quantifies access to clinical genomics, particularly amongst Indigenous populations. Using administrative data from clinical genetic health services across three Australian jurisdictions (states/territories), we investigate disparities in the scheduling and attendance of appointments among Aboriginal and/or Torres Strait Islander people, compared to non-Indigenous people. For 14,870 appointments scheduled between 2014-2018, adjusted Multivariate Poisson Regression models revealed that Aboriginal and/or Torres Strait Islander people were scheduled fewer appointments (IRR 0.73 [0.68-0.80], <0.001) and attended at lower rates (IRR 0.85 [0.78-0.93], <0.001). Within this population, adults, females, remote residents, and those presenting in relation to cancer or prenatal indications experienced the greatest disparity in access. These results provide important baseline data related to disparities in access to clinical genomics in Australia.

Background: Machado-Joseph Disease (MJD), or Spinocerebellar Ataxia Type 3 (SCA3), is a genetic disorder that causes progressive muscle weakness, loss of motor control, ataxia and permanent physical disability. Sleep disturbances are associated with MJD but remain poorly understood. Objective: To investigate frequency and characteristics of sleep disorders and their association with health-related quality of life and psychosocial wellbeing for Aboriginal Australians living with MJD. Methods: A convenience sample of MJD participants n = 24 participated in a semi-attended, ambulatory diagnostic sleep study to capture polysomnography, actigraphy and sleep diary data. Self-report measures collected were the Pittsburgh Sleep Quality Index (PSQI), STOP-BANG Questionnaire for Obstructive Sleep Apnoea (OSA), International Restless Legs Syndrome Study Group rating scale (IRLS), Kessler-5 (K5) and EuroQoL-5 Dimension (EQ5D). Caregivers (n = 22) reported EQ-5D, K5 and bed partners' sleep behaviour (Mayo Sleep Questionnaire-Informant). Environmental factors were measured. Results: We observed Nocturia, Sleep Related Leg Cramps, OSA, REM Behaviour Disorder, and RLS, respectively in 100%, 71%, 47%, 43%, and 33% of participants with a significant positive correlation between Body mass index (BMI) and Apnoea hypopnea index (AHI). The majority of sleep was spent in non-rapid eye movement sleep (NREM)-N2 stage (77.8% (67.7, 81.6)). Overcrowding (92%) and overnight care needs (42%) interrupted sleep. MJD participants and caregivers reported high psychological distress (K5 median 12.5 IQR 7, 16.5 & 8 IQR 6, 12 respectively). Conclusion: Poor sleep quality and sleep disturbances are prevalent among this cohort. Disease manifestations and environmental factors are driving factors. Larger sample sizes are required to predict risk factors and confirm observed associations.
RESUMO
BACKGROUND: Aboriginal and Torres Strait Islander people experience a greater burden of disease and die younger than non-Indigenous Australians, with Aboriginal people living in remote areas of the Northern Territory of Australia having the lowest life expectancy estimates. Despite a high burden of chronic disease among Aboriginal and Torres Strait Islander people, access to specialist health services remains low and models of care that increase engagement, may improve health outcomes. METHODS: We describe client and staff perspectives of a model of clinical genetics services provided by the MJD Foundation (MJDF) in geographically and culturally complex contexts within the Northern Territory of Australia. We seek to understand the MJDF model's success in supporting Aboriginal families with the familial, neurodegenerative condition Machado-Joseph disease and how it could be applied in the provision of other specialist services. Thematic analysis was undertaken on semi-structured interviews with primary health care staff (n = 2), Non-Aboriginal MJDF Staff (n = 7) and Aboriginal MJDF Clients / Community workers (n = 13). RESULTS: Four key themes regarding the MJDF model of service delivery were identified with the service being; 1) client led 2) accepting of various understandings of genetic disease causation 3) focused on relationships, continuity and trust between the service provider and the clients, and 4) committed to incorporating an inclusive whole-of-family practice. The MJDF model takes a community-based, person-and family-centred approach to successfully deliver effective specialist genetic health services in remote community settings. We propose that these approaches have broad application in the future design and delivery of specialist health services particularly in culturally complex settings.

Purpose: YolÅu are Aboriginal Australians from northeast Arnhem Land in the Northern Territory (NT). Machado-Joseph disease (MJD) prevalence in the NT Aboriginal population is the highest in the world. YolÅu living with progressive dysarthria associated with MJD could benefit from augmentative and alternative communication (AAC). However, there are no aided AAC systems in YolÅu languages. This research aimed to explore the views of YolÅu with MJD about communication, speech-language pathology (SLP) services and AAC.Method: A collaborative, culturally responsive research design was informed by Indigenist Research methodology and Constructivist Grounded Theory. YolÅu with MJD (n = 10) and their interested family members (n = 4) participated in interviews and created visual representations of their social networks. Data were analysed through an oral interpretive process with YolÅu researchers.Result: A YolÅu metaphor, GoÅdhu "Building understanding by hand", emerged as a culturally meaningful way to represent the core understandings required for speech-language pathologists (SLPs) to work effectively with YolÅu with MJD. Elements of this metaphor include seeking to understand the complex lived experiences of YolÅu with MJD, and working with families to explore the potential benefits of SLP services and AAC.Conclusion: YolÅu with MJD and their families want to work collaboratively with SLPs to develop bilingual AAC systems and culturally responsive SLP services that build on strengths of YolÅu culture and kinship to improve communication opportunities and participation.

INTRODUCTION: Emerging evidence indicates that rehabilitation can improve ataxia, mobility and independence in everyday activities in individuals with hereditary cerebellar ataxia. However, with the rarity of the genetic ataxias and known recruitment challenges in rehabilitation trials, most studies have been underpowered, non-randomised or non-controlled. This study will be the first, appropriately powered randomised controlled trial to examine the efficacy of an outpatient and home-based rehabilitation programme on improving motor function for individuals with hereditary cerebellar ataxia. METHODS AND ANALYSIS: This randomised, single-blind, parallel group trial will compare a 30-week rehabilitation programme to standard care in individuals with hereditary cerebellar ataxia. Eighty individuals with a hereditary cerebellar ataxia, aged 15 years and above, will be recruited. The rehabilitation programme will include 6 weeks of outpatient land and aquatic physiotherapy followed immediately by a 24- week home exercise programme supported with fortnightly physiotherapy sessions. Participants in the standard care group will be asked to continue their usual physical activity. The primary outcome will be the motor domain of the Functional Independence Measure. Secondary outcomes will measure the motor impairment related to ataxia, balance, quality of life and cost-effectiveness. Outcomes will be administered at baseline, 7 weeks, 18 weeks and 30 weeks by a physiotherapist blinded to group allocation. A repeated measures mixed-effects linear regression model will be used to analyse the effect of the treatment group for each of the dependent continuous variables. The primary efficacy analysis will follow the intention-to-treat principle. ETHICS AND DISSEMINATION: The study has been approved by the Monash Health Human Research Ethics Committee (HREC/18/MonH/418) and the Human Research Ethics Committee of the Northern Territory Department of Health and Menzies School of Health Research (2019/3503). Results will be published in peer-reviewed journals, presented at national and/or international conferences and disseminated to Australian ataxia support groups. TRIAL REGISTRATION NUMBER: ACTRN12618000908235.

Machado Joseph Disease (MJD) (spinocerebellar ataxia 3) is a hereditary neurodegenerative disease causing progressive ataxia and loss of mobility. It is the most common spinocerebellar ataxia worldwide. Among Aboriginal families of Groote Eylandt and related communities across Australia's Top End, MJD is estimated to be more prevalent than anywhere else in the world. This study explored lived experiences of individuals and families with MJD to determine what is important and what works best to keep walking and moving around. A collaborative qualitative exploratory study, drawing from constructivist grounded theory methods, was undertaken for data collection and analysis. Semi-structured in-depth interviews were conducted with individuals with MJD (n = 8) and their family members (n = 4) from the Groote Eylandt Archipelago where ~1500 Aboriginal people (Warnumamalya) live. Interviews were led by Warnumamalya community research partners in participants' preferred language(s). Participants described their experience of living with MJD, from 'knowing about MJD', 'protecting yourself from MJD' and 'adjusting to life with MJD'. While the specific importance of walking and moving around differed widely between participants, all perceived that walking and moving around enabled them to do what mattered most to them in life. 'Staying strong on the inside and outside' (physically, mentally, emotionally, spiritually) was perceived to work best to keep walking and moving around as long as possible. A framework that included personal and environmental strategies for staying strong emerged: 'Exercising your body', 'having something important to do', 'keeping yourself happy', 'searching for good medicine', 'families helping each other' and 'going country'. This study, the first to explore lived experiences of MJD in Australia, highlights the importance of maintaining mobility as long as possible. Strategies perceived to work best address physical and psychosocial needs in an integrated manner. Services supporting families with MJD need flexibility to provide individualised, responsive and holistic care.
