This article presents the development of a new device to assist with eating, aimed at stabilizing the movement of people who have movement disorders. The design was guided by insights gathered through focus groups, with occupational therapists and engineers, about the challenges faced by individuals who have movement disorders and difficulty in eating autonomously. The proposed assistive device prototype is designed to be fixed on a table and to support a spoon. The mechanism is designed so that the spoon maintains a position parallel to the ground for the user. Dampers and inertia allow stabilizing the user's motion. A preliminary trial with five individuals living with cerebral palsy is presented to assess the prototype's performance and to guide future iterations of the prototype. Task completion time generally decreased and movement fluidity generally improved when using the assistive device prototype. The prototype showed good potential in stabilizing the spoon for the user and improving movement fluidity.","PeriodicalId":282300,"journal":{"name":"Assistive technology : the official journal of RESNA","volume":" ","pages":"170-177"},"PeriodicalIF":1.8,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10400435.2020.1734111","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37682806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assistive robots have been used to provide access to play, and Forbidden Region Virtual Fixture (FRVF) guidance at the user interface could help the users make the robot traverse the play environment more efficiently because it behaves like virtual walls to follow. Eye gaze was used to indicate the user's intended target and generate the location of the virtual walls in a card sorting task. We eliminated the typical computer screen required for visual feedback to confirm gaze location, and examined the use of alternative feedback. In this feasibility study, first a group of adults without physical impairment tested the system with auditory and vibrotactile feedback modalities for the gaze fixation and with the virtual walls on and off for robot movement. Then case studies with children and individuals with physical impairments were performed. Even though gaze fixation feedback and the virtual wall did not improve the performance of adult participants without impairment, the feedback increased the speed and accuracy of the gaze fixation and the virtual walls improved the movement efficiency for the participants with impairment and a 6-year-old child without impairment.","PeriodicalId":282300,"journal":{"name":"Assistive technology : the official journal of RESNA","volume":" ","pages":"148-156"},"PeriodicalIF":1.8,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10400435.2020.1719557","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37566551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We randomized patients to the HAL group (8 hips), in which the HAL was used as part of physical therapy, or the control group (8 hips), in which only typical physical therapy was performed. Gait analysis was performed before and after surgery, and comparisons were made between the two groups. We evaluated the single support time (%), double support time (%), cadence (steps/min), velocity (cm/s), stride length (cm), and anteroposterior and lateral variability, and assessed the hip and knee joint range of motion in the sagittal plane. The results showed improvements in the hip extension angle and other gait parameters in the HAL group. Among gait-related problems after THA, a decreased peak hip extension angle is reported to be a significant factor that affects gait disability. This study revealed that HAL usage after THA seems to be a useful method to obtain sufficient extension angle.","PeriodicalId":282300,"journal":{"name":"Assistive technology : the official journal of RESNA","volume":" ","pages":"112-120"},"PeriodicalIF":1.8,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10400435.2020.1712498","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37519084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In experiment one, 3D hand parametric models were generated using anthropometric data collected with a scanning device from 120 Taiwanese adults. Experiment two examined the feasibility of constructing 3D-printed orthoses from the 3D hand parametric models through a case report on one client. The 19 values of the parameters measured from the client were imported into the 3D hand parametric models. An individual 3D hand mesh model approximating the client's hand was synthesized. The orthosis was precisely sketched and then printed. In usability testing, scores on the Quebec User Evaluation of Satisfaction with Assistive Technology were mostly high. The orthosis provided greater flexibility of hand movement and stronger support than the traditional, manually-formed orthosis.

The primary source of energy loss is due to the resistance of the drive wheels and casters on the ground. Specifically, manual wheelchairs have two major sources of frictional energy loss: rolling resistance and scrub torque. The objective of this study was to develop and validate component-level test methods to evaluate the energy loss properties of drive wheels and casters on different surfaces and with different applied loads. Rolling resistance is measured using a weighted coast-down cart and scrub torque is calculated by measuring the force required to rotate a plate that is loaded onto the tire's surface. Each test method was iterated and then applied to a cohort of drive wheels and casters. Both test methods demonstrated acceptable repeatability and the ability to distinguish energy loss parameters between common wheelchair components. The results show that caster and drive wheel energy losses can vary significantly across surfaces and with increased load on the casters. However, the findings also illuminate complex relationships between rolling resistance and scrub torque performance that embody a tradeoff in performance as applied to mobility during everyday life.","PeriodicalId":282300,"journal":{"name":"Assistive technology : the official journal of RESNA","volume":" ","pages":"91-103"},"PeriodicalIF":1.8,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10400435.2019.1697907","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37503497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, 2D drawings of the assistive device were created as the second step. For the third step the 3D scan of the individual's right hand was obtained. 3D scan of the right hand was transferred to CATIA program and the 3D printer is used in the manufacturing process for the fourth step. In the fifth step, we produced a low-cost novel writing assistive device. The writing device was introduced to the disabled individual and training was given regarding its practical use in the final step teaching the use of the device.

In many countries, social protection systems are a gateway to accessing assistive devices either through health insurance, integration in Universal Health Coverage (UHC) packages, subsidies, cash transfers or direct provision. However, the broader issues of access to AT (lack of awareness, information, availability, human resources, etc.) are compounded by barriers to social protection. In low- and middle-income countries globally, less than 20% of persons with significant disabilities, who are likely to need AT, receive disability benefits. This paper reflects on the relation of AT and disability-related costs, the evolution of the role of social protection in line with the CRPD, and the different social protection mechanisms used at the national level to provide access to AT. It further highlights some of the key issues to be tackled by social protection systems to enhance access to AT, with a focus on low- and middle-income countries.","PeriodicalId":282300,"journal":{"name":"Assistive technology : the official journal of RESNA","volume":" ","pages":"102-108"},"PeriodicalIF":1.8,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39637609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to environmental factors such as the quality of sidewalks for wheelchair users or cultural attitudes for those that require eyeglasses or prostheses, obstacles include: lack of awareness of the existence of certain technologies; absence of public policies supporting local availability and affordability; lack of products which have the adequate size, type, or quality; and insufficient personnel to provide referrals, fitting, training, and repairs.

The capabilities of digital devices have been improving so impressively for so long, that the assumption that in parallel the same is happening with accessibility is common. Unfortunately, accessibility for persons with disabilities is neither certain nor constant, and in fact, a conscious and systemic effort is required to ensure that the potential of digital technologies for inclusion is realized.Digital accessibility is best understood as a chain of dependencies where training, hardware, software, content, and standards must work together harmoniously, and each of these elements must be understood as a dynamic process. For example, smartphones can be incompatible with hearing aids required by the deaf, touch screens too sensitive for those with motor impairments, and web pages often lack the text labels needed by screen reading software used by the blind. Even if each of these examples is fixed, the accessibility may be short lived if the production process behind that hardware or software was not corrected, as the digital world is constantly being updated. Training, hardware design, software development, content production, and standards definition processes, must be pursued taking accessibility and affordability into account.","PeriodicalId":282300,"journal":{"name":"Assistive technology : the official journal of RESNA","volume":" ","pages":"27-34"},"PeriodicalIF":1.8,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39873170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
