Mao A, Jiang H, Dong L, Yan M, Shan Y. Assistive products for older adults in China: self-reported need, services, and satisfaction. Disabil Rehabil Assist Technol 2024:1-9. [PMID: 38635346 DOI: 10.1080/17483107.2024.2338134] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 03/27/2024] [Indexed: 04/20/2024]
Abstract
Purpose: Older adults may abandon or discontinue the use of assistive products due to low levels of satisfaction. Only few studies have examined need and satisfaction related to the use of assistive products for this group in China. As such, research is needed to improve satisfaction with assistive products and related services. Method: This study used technology acceptance theory to examine the self-reported need for, and ownership of, assistive products among older adults in China, as well as to examine the association between services and satisfaction with assistive products; the underlying mechanism of this association was also assessed. The current study used the rapid assistive technology assessment (rATA) questionnaire designed by the World Health Organization (WHO) for stratified and cluster sampling. A total of 2,158 older adults living in China were interviewed. The multiple regression analysis was used to examine the independent and interactive associations between services and satisfaction. Heterogeneity and robustness tests were also undertaken.Results: The self-reported need for assistive products pertained mainly to vision, and together with ownership, the need gap has not yet been addressed. Both pre-sale (β = 0.600, p < 0.01) and follow-up services (β = 0.270, p < 0.01) were positively correlated with satisfaction, which in turn shows heterogeneity when it comes to the types of assistive products.Conclusion: Providing accessible services, especially follow-up services, will help older adults be more satisfied with their assistive products, thus ultimately ensuring the continued use of products.

Abstract
PURPOSE To describe the barriers and facilitators of the assistive technology service delivery process (AT-SDP), based on the perspectives of assistive technology service professionals (ATPs) and assistive technology (AT) service users. METHODS We conducted semi-structured interviews with nine AT users and eight ATPs in South Korea. The data were analyzed using a constant comparative approach based on the grounded theory. RESULTS AT users and ATPs identified common barriers in the assessment, matching, and implementation of the AT-SDP. In the assessment process, the preparation of detailed selection criteria was suggested for assistive technology devices (ATDs). Insufficient linkages on assessments among institutions providing AT services was a reported barrier, and standardized evaluation tools were suggested to address this issue. In the matching process, to meet users' needs, versatility in the characteristics or type of ATD was highlighted. In the implementation process, participants emphasized the need to shorten the time required during the delivery process. Along with these facilitators, institutional support, including staffing securement, the establishment of AT centres, and funding policies were recommended to facilitate the AT-SDP. CONCLUSIONS Our results highlight the importance of government support and considering realistic funding levels to overcome the barriers reported by AT users and ATPs.

Abstract
OBJECTIVE We describe a networked, two-user virtual reality (VR) power wheelchair (PWC) simulator system in which an actor (client) and an observer (clinician) meet. We then present a study with 15 observers (expert clinicians) evaluating the effect of three principal forms of viewpoint control (egocentric-egomotion, egocentric-tethered, and client-centric) on the observer's assessment of driving tasks in a virtual environment (VE). BACKGROUND VR allows for the simulation and assessment of real-world tasks in a controlled, safe, and repeatable environment. Observing users' movement behavior in such a VE requires appropriate viewpoint control for the observer. The VR viewpoint user interface should allow an observer to make judgments equivalent or even superior to real-world situations. METHOD A purpose-built VR PWC simulator was developed. In a series of PWC driving tasks, we measured the perceived ease of use and sense of presence of the observers and compared the virtual assessment with real-world "gold standard" scores, including confidence levels in judgments. RESULTS Findings suggest that with more immersive techniques, such as egomotion and tethered egocentric viewpoints, judgments are both more accurate and more confident. The ability to walk and/or orbit around the view significantly affected the observers' sense of presence. CONCLUSION Incorporating the observer into the VE, through egomotion, is an effective method for assessing users' behavior in VR with implications for the transferability of virtual experiences to the real world. APPLICATION Our application domain serves as a representative example for tasks where the movement of users through a VE needs to be evaluated.

Effectiveness of the Virtual Reality System Toyra on Upper Limb Function in People with Tetraplegia: A Pilot Randomized Clinical Trial. BIOMED RESEARCH INTERNATIONAL 2016; 2016:6397828. [PMID: 26885511 PMCID: PMC4739467 DOI: 10.1155/2016/6397828] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/01/2015] [Revised: 12/20/2015] [Accepted: 12/21/2015] [Indexed: 12/04/2022]
Abstract
The aim of this study was to investigate the effects of a virtual reality program combined with conventional therapy in upper limb function in people with tetraplegia and to provide data about patients' satisfaction with the virtual reality system. Thirty-one people with subacute complete cervical tetraplegia participated in the study. Experimental group received 15 sessions with Toyra(®) virtual reality system for 5 weeks, 30 minutes/day, 3 days/week in addition to conventional therapy, while control group only received conventional therapy. All patients were assessed at baseline, after intervention, and at three-month follow-up with a battery of clinical, functional, and satisfaction scales. Control group showed significant improvements in the manual muscle test (p = 0,043, partial η (2) = 0,22) in the follow-up evaluation. Both groups demonstrated clinical, but nonsignificant, changes to their arm function in 4 of the 5 scales used. All patients showed a high level of satisfaction with the virtual reality system. This study showed that virtual reality added to conventional therapy produces similar results in upper limb function compared to only conventional therapy. Moreover, the gaming aspects incorporated in conventional rehabilitation appear to produce high motivation during execution of the assigned tasks. This trial is registered with EudraCT number 2015-002157-35.

Abstract
[Purpose] The study purpose was to investigate the test-retest reliability of the Quebec
User Evaluation of Satisfaction with assistive Technology 2.0-Korean version (QUEST-K) for
individuals with traumatic spinal cord injury. [Subjects and Methods] Seventy participants
with spinal cord injury were enrolled in this study. The participants were assessed using
the QUEST-K in two sessions conducted 3 days apart. This study also utilized the spinal
cord independence measure III and modified Barthel index for determining their validity
concurrently with the QUEST-K. [Results] The test-retest reliability (intraclass
correlation coefficient 0.855) of the QUEST-K was high, indicating a good agreement. The
results of the QUEST-K testing were not substantially positively correlated with those of
the spinal cord independence measure III (r = −0.075) and Modified Barthel Index
(r=−0.138). [Conclusion] The test-retest reliability of the QUEST-K was high in
individuals with spinal cord injury. The QUEST-K could be a reliable measure for
evaluating the satisfaction with assistive technology during functional performance in
patients with spinal cord injury. The ability of the QUEST-K to detect actual changes is
acceptable for research and clinical settings.

Abstract
[Purpose] This study aimed to determine the effectiveness of joystick-controlled video
console games in enhancing subjects’ ability to control power wheelchairs. [Subjects and
Methods] Twenty healthy young adults without prior experience of driving power wheelchairs
were recruited. Four commercially available video games were used as training programs to
practice joystick control in catching falling objects, crossing a river, tracing the route
while floating on a river, and navigating through a garden maze. An indoor power
wheelchair driving test, including straight lines, and right and left turns, was completed
before and after the video game practice, during which electromyographic signals of the
upper limbs were recorded. The paired t-test was used to compare the differences in
driving performance and muscle activities before and after the intervention. [Results]
Following the video game intervention, participants took significantly less time to
complete the course, with less lateral deviation when turning the indoor power wheelchair.
However, muscle activation in the upper limbs was not significantly affected. [Conclusion]
This study demonstrates the feasibility of using joystick-controlled commercial video
games to train individuals in the control of indoor power wheelchairs.
