Smart home automation technology to support caring of individuals with Alzheimer's disease and related dementia: an early intervention framework.

PURPOSE: Home automation technology comprising of Internet of Things and Smart gadgets is a rapidly growing industry that is projected to have a major scope for ageing-in-place and caregiving. This study examined the feasibility and cost-benefits of a personalized home automation intervention for care of individuals with Alzheimer's disease and related dementia (ADRD) with emphasis on their safety and independence, and reduction of care burden. METHODS: A mixed method intervention study was conducted with five dyads each comprising of a caregiver and care recipient with ADRD. Each dyad received personalized home automation intervention with individualized goals centred on home safety, activity engagement, and caregiver-recipient connectivity. The goals were created and monitored using goal attainment scaling (GAS). The dyads were followed up after three months with a home visit and interview. Goal attainment scoring and thematic analysis of the interviews were conducted to examine the findings from the study. RESULTS: All dyads indicated positive goal attainment between pre and post intervention. Goals that were met were complimented by the categories of peace of mind, self-efficacy, and care recipient engagement, while unmet goals as well as complexities with the technology were elucidated under challenges. Overarching and conceptually linked themes from the study were unfamiliarity, value, and timing. CONCLUSION: Home automation technology has the potential to be adapted to promote independence and safety of individuals with ADRD while relieving care burden. Nonetheless, we propose an early intervention framework to overcome identified challenges and optimize the technology's usability and sustainability.IMPLICATIONS FOR REHABILITATIONHome automation involving Internet of Things and Smart gadgets has gained rapid popularity owing to the comfort and connectivity they provide to mainstream consumers.The technology has an emerging significance to ageing-in-place and care of individuals with Alzheimer's Disease and Related Dementia (ADRD) as it can be adapted and implemented to enhance home safety and activity engagement of the care recipients while also strengthening their connectivity with the caregivers.Unfamiliarity with the technology compounded by the progression of ADRD can, however, be detrimental to its adoption.Individualized focus and early integration of the technology for caregiver-care recipient dyads can mitigate these challenges and optimize its usability and long-term value in relation to ageing-in-place and caregiver wellbeing.

Validation of Smartphone Accelerometry for the Evaluation of Sit-To-Stand Performance and Lower-Extremity Function in Older Adults.

This study tested the concurrent and construct validity of smartphone accelerometry measurement of sit-to-stand (STS) performance in individuals aged 65-89 years. Normal and fast STS times were recorded by smartphone accelerometer, force plate, and video motion systems concurrently, and isokinetic knee extension power and STS whole-body power were obtained. Normal and fast speed STS times from a smartphone accelerometer agreed closely with force plate and motion system methods (mean difference = 0.04 s). Normal and fast STS times were inversely related to isokinetic knee extension power (r = -.93, p < .001 and r = -.82, p < .001, respectively) and STS whole-body power (r = -.76, p < .001 and r = -.70, p < .001, respectively). The STS time obtained from a smartphone accelerometer was equivalent to the established, precise measures of STS time and was related to lower-extremity power, making it a potentially useful metric of lower-extremity function.

Unpaid Caregiving and Aging in Place in the United States: Advancing the Value of Occupational Therapy.

Unpaid caregivers are often expected to help family members or friends overcome activity limitations and participation restrictions to successfully age in place. Caregivers assume multiple responsibilities, such as managing their own physical and psychosocial needs and navigating a complex health care system, and many feel ill equipped to fulfill the necessary health care responsibilities for their care recipients. Underprepared caregivers may cause poor outcomes for care recipients. Federal and state policy proposals call attention to the need to better support caregivers, especially as their numbers increase. Occupational therapy practitioners are well positioned to effectively engage caregivers as they navigate the health care system. The occupational therapy process looks broadly at the functional abilities, environmental contexts, and occupational demands that play a pivotal role in successful aging in place for clients and better outcomes for their caregivers. Now is the time to define occupational therapy's distinct value to this area.

Stimulating Research to Enhance Aging in Place.

Older adults may benefit from interventions to successfully age in place. Research has an opportunity to test interventions and implementation strategies to fulfill the needs of older adults through collective evidence building. The purpose of this article is to describe the proceedings of the American Occupational Therapy Foundation (AOTF) 2019 Planning Grant Collective and describe the areas of research that were identified as critical. The AOTF convened scientists with expertise in the area of aging in place to catalyze research on aging in place for older adults. Four priority areas in the aging in place literature were highlighted: (a) identification of factors that support aging in place, (b) classification of processes by which family members and care partners are included in aging in place efforts, (c) categorization of technology supporting older adults to age in place, and (d) development of science that clarifies implementation of evidence-based practice.

Promoting Information Communication Technology Adoption and Acceptance for Aging-in-Place: A Randomized Controlled Trial.

The prevailing digital divide along with barriers to information communication technology (ICT) adoption among older adults is well elucidated. To contribute evidence on ICT education, a 2-year randomized controlled trial verified the long-term effect of a novel individualized ICT training program for older adults in demographic cohorts who are known to underutilize ICT (n = 42 in the training and n = 43 in a control group). Mixed-model repeated measures analysis of data was conducted from baseline and 6-month intervals (df = 4, 1) post training. Older adults in the training group engaged in a wide range of leisure (p = .03), health management (p = .006), and instrumental activities of daily living (p = .02) significantly more than those in the control group. They also reported significantly enhanced technology acceptance and sustained sense of independence in key ICT-based activities. The study supports the implementation of one-on-one ICT training programs to promote access and utilization of digital resources for aging-in-place.

Reliability and validity of the usability scale for assistive technology for computer access: a preliminary study using video-based evaluation.

Objective: The focus of this research was to establish the interrater reliability and content validity of the Usability Scale for Assistive Technology-Computer Access (USAT-CA), an evaluation tool to facilitate selection of computer access AT devices for individuals with disabilities.Methods: AT providers used the USAT-CA to evaluate two clients with physical disabilities interacting with their computer. Initially, an expert cohort of six providers used a draft version of the USAT-CA and provided feedback. Subsequently, 13 AT providers used a revised version to evaluate the clients. The providers filled out a content validation questionnaire and recommended computer access solutions for each client.Results: Overall intraclass correlation coefficient (ICC) scores were 0.8 and 0.9 for the AT provider cohorts, respectively. In each domain, ICC scores ranged from 0.7 to 0.9. There was agreement among the providers on the tool's comprehensiveness, clarity, time needed, and utility. For Client 1, 16 out of 19 AT providers recommended speech recognition software in combination with selected direct selection interfaces. For Client 2, 14 out of 19 providers recommended ergonomic and workspace modifications.Conclusion: The USAT-CA was found to have good to excellent inter-rater reliability, good content validity, and consistency in recommendations to optimize client-computer interaction.

Virtual reality-based treatment for regaining upper extremity function induces cortex grey matter changes in persons with acquired brain injury.

BACKGROUND: Individuals with acquired brain injuries (ABI) are in need of neurorehabilitation and neurorepair. Virtual anatomical interactivity (VAI) presents a digital game-like format in which ABI survivors with upper limb paresis use an unaffected limb to control a standard input device and a commonplace computer mouse to control virtual limb movements and tasks in a virtual world. METHODS: In a prospective cohort study, 35 ambulatory survivors of ABI (25/71% stroke, 10/29% traumatic brain injury) were enrolled. The subjects were divided into three groups: group A received VAI therapy only, group B received VAI and physical/occupational therapy (P/OT), and group C received P/OT only. Motor skills were evaluated by muscle strength (hand key pinch strength, grasp, and three-jaw chuck pinch) and active range of motion (AROM) of the shoulder, elbow, and wrist. Changes were analyzed by ANOVA, ANCOVA, and one-tailed Pearson correlation analysis. MRI data was acquired for group A, and volumetric changes in grey matter were analyzed using voxel-based morphometry (VBM) and correlated with quantified motor skills. RESULTS: AROM of the shoulder, elbow, and wrist improved in all three groups. VBM revealed grey matter increases in five brain areas: the tail of the hippocampus, the left caudate, the rostral cingulate zone, the depth of the central sulcus, and the visual cortex. A positive correlation between the grey matter volumes in three cortical regions (motor and premotor and supplementary motor areas) and motor test results (power and AROM) was detected. CONCLUSIONS: Our findings suggest that the VAI rehabilitation program significantly improved motor function and skills in the affected upper extremities of subjects with acquired brain injuries. Significant increases in grey matter volume in the motor and premotor regions of affected hemisphere and correlations of motor skills and volume in nonaffected brain regions were present, suggesting marked changes in structural brain plasticity. TRIAL REGISTRATION: The trial "Limitations of motor brain activity - use of virtual reality for simulation of therapeutic interventions" has been registered under reference number ISRCTN11757651 .

Caregiver perspectives on a smart home-based socially assistive robot for individuals with Alzheimer's disease and related dementia.

Purpose: Innovative assistive technology can address aging-in-place and caregiving needs of individuals with Alzheimer's disease and related dementia (ADRD). The purpose of this study was to beta-test a novel socially assistive robot (SAR) with a cohort of ADRD caregivers and gather their perspectives on its potential integration in the home context.Methods: The SAR involved a programmable research robot linked with commercially available Internet of things sensors to receive and respond to care recipient's behaviour. Eight caregivers observed the SAR perform two care protocols concerning the care recipient's daily routine and home safety, and then participated in a focus group and phone interview. The researchers used grounded theory and the Unified Theory of Acceptance and Use of Technology as a framework to gather and analyse the data.Results: The caregivers' asserted the potential of the SAR to relieve care burden and envisioned it as a next-generation technology for caregivers. Adoption of the SAR, as an identified theme, was subject to the SAR's navigability, care recipient engagement, adaptability, humanoid features, and interface design. In contrast, barriers leading to potential rejection were technological complexity, system failure, exasperation of burden, and failure to address digital divide.Conclusion: From a broader outlook, success of SARs as a home-health technology for ADRD is reliant on the timing of their integration, commercial viability, funding provisions, and their bonding with the care recipient. Long-term research in the home settings is required to verify the usability and impact of SARs in mediating aging-in-place of individuals with ADRD.IMPLICATIONS FOR REHABILITATIONSocially assistive robots (SARs), an emerging domain of assistive technology, are projected to have a crucial role in supporting aging-in-place of individuals with Alzheimer's disease and related dementia (ADRD).Caregivers of individuals with ADRD who observed and interacted with a novel SAR asserted their acceptance of the technology as well as its scope and feasibility for the upcoming generation of caregivers.Navigability, care recipient engagement, adaptability, humanoid features, and interface design were stated to be critical factors for SAR's acceptance by caregiver and care recipient dyads.In contrast, technological complexity, system failure, exasperation of burden, and failure to address digital divide are detrimental to SAR's adoption.Several design and implementation requirements must be considered towards the full-scale development and deployment of the SARs in the home context.

Determinants of information communication and smart home automation technology adoption for aging-in-place.

Purpose ­: Smart home (SH) internet of things can promote home safety, health monitoring and independence of older adults to age-in-place. Despite its commercial growth, low adoption rates of the technology among aging consumers remain a major barrier. The purpose of this study is to examine SH technology ownership of older adults and its causal pathways with demographics, health and functioning, home safety and information communication technology (ICT) use. Design/methodology/approach ­: A survey on technology-mediated aging-in-place was completed by 447 respondents, 65 years and older. Structural equation modeling was used to underscore the causal pathways among demographics, health, independence and home safety, ICT and home automation technology adoption. Findings ­: The study found that ICT usability, home security and independence have a significant direct effect on SH ownership. Demographics had no significant direct effect, but its influence was mediated through ICT usability. With home safety as mediator, physical impairment, falls and accidents and independence had a significant association with SH ownership. Similarly, increased social support (mediated through home security) decreased the probability of SH automation ownership. Originality/value ­: The findings signify the perceived usefulness of SH automation as theorized in technology acceptance models.

Profiles and Predictors of Smart Home Technology Adoption by Older Adults.

The commercial popularity of smart home (SH) technology has broadened the scope of aging-in-place and home health occupational therapy. The objective of this article is to examine ownership of SH technology by older adults, their readiness to adopt SH technology, and identify the client factors relating to the adoption. A survey of older adults aged 60 and above living in the community was conducted. Respondents (N = 445) who were women; in the age group of 60 to 70 years; living in a two-level home, with a body function impairment; with a fall history; and experienced in information and communication technology (ICT) were significantly likely to be "brisk adopters" of SH (p < .05). Stepwise regression model identified marital status, home security, and overall ICT ownership as the predictors of SH ownership, whereas being female, concern over home security, and perceived independence contributed to SH readiness (p < .05). Consideration of the identified client profiles, health, and personal factors will strengthen SH integration for aging-in-place.

Multi-stakeholder perspectives on information communication technology training for older adults: implications for teaching and learning.

Objectives: The objective of this research was to identify and conceptualize barriers and strategies for effective implementation of information communication technology (ICT) training for older adults. Methods: A grounded theory approach was used to collect and analyze qualitative data from 61 participants in three stakeholder groups: older-adult ICT trainees, care providers and ICT trainers. Results: Care providers expressed older adults' reluctance, lack of affinity, fears and socio-contextual attributes as barriers to overcome with ICT training. ICT trainers highlighted motivation, trainer-trainee relationship, patience, self-reliance and mutual value as strategic themes. ICT trainees elucidated occupational accomplishment, challenges and a sense of competence as themes from their experience with training. Discussion: While digital literacy and skill building have traditionally been the key focus of ageing-centred ICT training, a deeper approach to address internal (personal) and external (socio-contextual) barriers, as conceptualized in the study finding, is vital in yielding successful outcomes. Implications for rehabilitation Information communication technology (ICT) is a vital resource for older adults to age-in-place and for health professionals in delivery of tele-rehabilitation. Family members and care providers realize the scope of ICT for ageing-in-place but raise doubts on the inherent motivation and abilities of older adults to adopt ICT. On the other hand, older adults who engage in one-on-one ICT training value their new-found sense of accomplishment and competence in using the Internet and social media. Graduate students who provided the training greatly appreciate their own learning experience, and stress the need for mutual trust, patience and simplicity in teaching ICT. A major precursor to imparting digital literacy and skills in older adults who lack ICT exposure is to help them overcome deep-seated attitudinal and socio-contextual barriers through a one-on-one approach.

Text entry rate of access interfaces used by people with physical disabilities: A systematic review.

This study systematically reviewed the research on assistive technology (AT) access interfaces used for text entry, and conducted a quantitative synthesis of text entry rates (TER) associated with common interfaces. We searched 10 databases and included studies in which: typing speed was reported in words per minute (WPM) or equivalent; the access interface was available for public use; and individuals with physical impairments were in the study population. For quantitative synthesis, we used only the TER reported for individuals with physical impairments. Studies also had to report the sample size, and the average and standard deviation for the TER data. Thirty-nine studies met the criteria for quantitative synthesis. Studies involved seven interface types: standard keyboard typing, on-screen keyboard (OSK) with cursor selection, OSK with scanning selection, automatic speech recognition (ASR), Morse code, brain-computer interface (BCI), and other. ASR, standard keyboard, cursor OSK, and scanning OSK had at least four studies and 30 subjects, with TER averaging 15.4, 12.5, 4.2, and 1.7 WPM, respectively. When combined with measurements of a particular client's text entry performance, the TER from this review can be used within an evidence-based decision-making process for selecting control interfaces.

Effect of diagnosis, body site and experience on text entry rate of individuals with physical disabilities: a systematic review.

OBJECTIVE: This study systematically reviewed the research on computer text entry by people with physical disabilities, and conducted a quantitative synthesis of text entry rates associated with individuals' diagnosis, body site used with the interface and their level of experience. METHOD: We searched 10 databases and included studies in which: typing speed was reported; the access interface was available for public use; and individuals with physical impairments were in the study population. For quantitative synthesis, we used only the text entry rates (TER) reported for individuals with physical impairments; studies also had to report the sample size, and the average and standard deviation for the text entry rates. RESULTS: Thirty-nine studies involving 248 subjects met the criteria for quantitative synthesis. Cerebral palsy was associated with significantly slower TER, at 5.5 wpm, than muscular dystrophy (12.5 wpm), spina bifida (10.4 wpm), SCI high cervical (10.1 wpm) and SCI low cervical (13.3 wpm). Among the 19 body sites represented, the Fingers bilateral category had the highest average, at 17.72 wpm. Head (2.92 wpm) and Hand (non-typing) (3.95 wpm) were each associated with significantly slower TER than Hands unspecified, Fingers bilateral, Hand with control enhancer, Voice and Mouth. The three levels of experience examined, LowPlus, Medium and High, provided very similar TER. CONCLUSION: This study contributes external evidence for service providers who provide computer access interventions for individuals with disabilities. The analyzed text entry performances serve as benchmarks to be used as guidelines during interface selection and training. Implications for Rehabilitation The median text entry rate (TER) across the literature for individuals with physical disabilities is 7.0 wpm. TER is affected by a user's diagnosis and the body site used for typing. These TER data can serve as diagnostic norms and benchmarks to be used as guidelines during interface selection and training. We recommend that practitioners measure text entry rate with clients, to place their performance in the context of these results and provide a baseline against which to measure effectiveness of an intervention.

A survey of assistive technology service providers in the USA.

This study investigates perspectives of assistive technology service (ATS) providers regarding their education and training, interdisciplinary standards of practice, use of a common language framework, funding policies, utilization of evidence and outcomes measurement. A survey underpinned by AT legislations and established guidelines for practice was completed by 318 certified AT providers. More than 30% of the providers reported their education and training as inadequate to fulfil four of the seven primary roles of ATS. Nearly 90% of providers expressed awareness of the International Classification of Functioning, Disability and Health (ICF) domains for interdisciplinary communication. However, only 45% felt that they could effectively utilize the ICF in their documentation. About 75% of the providers acknowledged the lack of a recognized standard for the provision of services. Prevailing inadequacies in funding were negatively impacting the quality of ATS, as expressed by 88% of respondents. Translation of evidence to practice was identified as a major challenge by 41% of service providers. Providers were predominantly documenting outcomes through informal interviews (54%) or non-standard instruments (26%). Findings support the need for strengthening professional curriculum, pre-service and in-service training and an established standard to support effective, interdisciplinary AT services and data collection to support public policy decisions. Implications for Rehabilitation This study validates the need to strengthen education and training of AT service providers by enhancing professional curriculum as well as their engagement in pre-service and in-service training activities. This study draws attention to health care funding policies and practices that critically impact the quality of AT services. This study signifies the need for an established interdisciplinary standard among AT professionals to support effective communication, service coordination and outcomes measurement.

A home-based individualized information communication technology training program for older adults: a demonstration of effectiveness and value.

PURPOSE: To demonstrate the effectiveness and value of a home-based information communication technology (ICT) training program for older adults. METHODS: Thirteen older adults were provided in-home ICT training by graduate occupational therapy students using an iPad. The breadth and frequency of ICT use, perspectives on technology, and perceived independence were recorded at baseline, during the 3-month training and at follow-up, along with an end-of-study questionnaire. Non-parametric Friedman analysis was conducted to verify trends in the outcome measures. The qualitative data were examined by content analysis. RESULTS: Participants' breadth of ICT activities showed a significant trend across 6 months. Leisure accounted for the significant increase, while health management and social connections activities increased modestly. A positive trend in participants' perspectives on technology was evident along with a marginal increase in perceived independence. Participants' perspectives were thematically categorized as technology experiences, interactions with coach, training approach, and specific activities. As reflection of the training program's value, 12 of the 13 participants took ownership of the iPad at the end of the study. CONCLUSION: Building capacity of older adults to utilize the multifaceted potential of ICT is critical in addressing declines in health, impending disabilities, and social isolation. Implications for Rehabilitation A one-on-one home-based individualized information communication technology (ICT) training program for older adults could result in a progressive increase in the breadth of online activities carried out by them. Specifically, the increase in their usage of ICT could be expected in leisure-based online activities. Individualized training programs designed based on needs, priorities, and learning style of older adults could have a positive impact on their technological perspectives and intrinsic motivation to adopt ICT.

Pilot study: Computer-based virtual anatomical interactivity for rehabilitation of individuals with chronic acquired brain injury.

Deficiencies in upper-limb motor function and executive functioning can compromise an affected individual's ability to complete everyday activities. Impaired motor and executive functioning therefore pose a risk to increasing numbers of veterans who have been diagnosed with acquired brain injury. This article reports on changes in upper-limb motor function and executive functioning of 12 adult participants with chronic acquired brain injury using a novel, computer-based, motor and cognitive rehabilitation program called PreMotor Exercise Games (PEGs). Manual muscle, goniometric range of motion, and dynamometer assessments were used to determine motor functioning while the Executive Function Performance Test measured cognitive functioning. A three-level repeated measures design was conducted to determine changes pre- and postintervention. Participants demonstrated significant improvement in shoulder (p = 0.01) and wrist (p = 0.01) range of motion and clinically relevant improvement for elbow range of motion. Participants demonstrated clinically relevant improvement in shoulder, elbow, and wrist strength. Finally, participants demonstrated significant improvement in executive functioning (p < 0.05). Using PEGs as a modality for both motor and cognitive intervention is a potentially beneficial adjunct to rehabilitation and warrants further study.

An examination of occupation-based, client-centered, evidence-based occupational therapy practices in New Hampshire.

This study surveyed occupational therapy practitioners to gain a better understanding of the nature of occupational therapy practices in the State of New Hampshire. A questionnaire was developed and distributed to a sample of practitioners working in New Hampshire to gather information regarding the extent to which occupation-based, client-centered, evidence-based services were being provided. Results suggested that practitioners highly value these service delivery attributes. However, day-to-day practice decisions regarding evaluation methods, where to conduct intervention sessions, goal writing, and choices of intervention activities suggest a stronger emphasis on the evaluation and remediation of specific performance skill and body function deficits, rather than on client performance of desired occupations. In light of the findings, the discrepancy between practitioner values and daily clinical practices is discussed, along with the challenges inherent in providing authentic, evidence-based occupational therapy.

Comparative observations of learning engagement by students with developmental disabilities using an Ipad and computer: a pilot study.

This study examined the use of the Apple iPad for learning by children with developmental disabilities (DD), including those on the autism spectrum. A single case design was used to record the participation of four students with DD when taught with their standard computer at baseline, followed by the introduction of the iPad. A six-component participation scale was developed to quantify observations of these students during the learning sessions. Visual analysis of data indicated no differences in participation with the iPad as compared to the computer for three of the four subjects. One subject appeared to have notably higher participation with the iPad. Individual variations were identified in each student along with some common concerns with attention, task persistence, and goal directed behavior with use of the iPad. Student academic scores improved during the course of iPad use. Nevertheless, the findings drawn from this pilot study do not justify the use of the iPad over the computer (and vice versa) for achieving academic goals in students with DD. The need to document best practices and barriers in use of emerging touch-tablet devices to support individualized education was clearly evident.

Consumer perspectives on the usability and value of the iBOT(®) wheelchair: findings from a case series.

PURPOSE: The iBOT(®) is an advanced power wheelchair introduced in 2003 for people with mobility impairments to enhance their independence and community access. Although this innovation soon gained popularity, the production of this wheelchair was recently stopped owing to the lower-than-expected sale figures. In this scenario, this study examines the impact of this wheelchair on current consumers by highlighting its usability in multiple contexts and verifying the value associated with its ownership. METHOD: Seven active consumers of the iBOT(®) were interviewed using a mixed method approach. Participants discussed and rated the iBOT's usability in relation to their standard power wheelchair and shared their perceived value for it. A content analysis was used to elucidate the qualitative data, whereas the quantitative data was analyzed using descriptive and non-parametric comparisons to compute differences in consumer ratings for the two wheelchairs. RESULT: Results, although statistically non-significant (α < 0.05), indicated the iBOT(®) to be a highly multi-functional wheelchair with relatively superior usability in workplace (p = 0.15), community (p = 0.18) and outdoors (p = 0.1). Participants greatly valued its capability to expand their mobility in otherwise inaccessible environments and to enhance their social participation through eye level communication. CONCLUSION: The iBOT(®) serves as an exemplar to promote interest and funding for advanced AT devices for people with disabilities. [Box: see text].

Exploring occupational justice in consumer perspectives on assistive technology.

BACKGROUND: Occupational justice is an emerging paradigm in the provision of occupational therapy services. Assistive technology (AT) services, a key practice domain in occupational therapy, facilitate the participation of individuals with disabilities in all major occupations. PURPOSE: The goal of this study was to explore personal meanings of occupational justice among consumers of AT and to propose strategies that integrate values of occupational justice in AT services. METHODS: A content analysis of interviews with seven consumers of AT devices was employed. Themes relevant to the four conceptual definitions of occupational injustice, namely marginalization, alienation, deprivation, and imbalance, were identified. FINDINGS: Four corresponding themes were inherent in the consumer experiences: ability to exercise choices through use of AT devices, using AT to achieve optimum occupational potential, empowerment through AT services, and personal relation to the AT device. Specific issues within these themes are classified and described according to the four conceptual definitions of occupational justice. IMPLICATIONS: The application of occupational justice is essential to promote client-centred AT services particularly in evaluation of needs, selection and acquisition of AT devices, and training and support for use of AT devices.
