Abstract Background: Advanced assistive technologies (AAT) aim to exploit the vast potential of technological developments made in the past decades to improve the quality of life of people with disabilities. Combining complex robotic technologies with the unique needs of people with disabilities requires a strong focus on user-centered design to ensure that the AAT appropriately addresses the daily life struggles of target users. The CYBATHLON aims to promote this mindset by empowering the AAT target users (“pilots”) to compete on race tracks that represent daily life obstacles. The objective of this work was to investigate the influence of the CYABTHALON on AAT technology development, acceptance, and user involvement (i.e., application of user-centered design).Methods: With an online survey targetting the pilots and technical leads of teams preparing for the CYBATHLON 2020 Global Edition, we investigated to what extent the pilots were involved in device development and how this influences the perceived daily life usability of the showcased AAT. Furthermore, the effects of user-centered design variables on the individual race performances were analyzed.Results: A total of 81 responses from 35 pilots and 46 technical leads were collected in the two weeks prior to the event. Of all teams partaking in the included disciplines of the CYBATHLON 2020 Global Edition, 81.8% (36 of 44) were included in the study. User-centered design appeared to be a prevalent practice among the teams, as 85.7% of all pilots reported a certain level of involvement. However, only 25.5% of the pilots reported daily life usage, despite QUEST usability scores of both respondent groups showing moderate to high satisfaction with the respected AAT across all investigated disciplines. An explorative linear mixed model indicated that daily life usage (p < 0.05) and prolonged user involvement (e.g. more than 2 years, p < 0.001) have a significant positive effect on the race performance at the competition.Conclusions: We conclude that the CYBATHLON positively fullfills its conceptual goals of promoting active participation and inclusion of people with disabilities in the design and evaluation of AAT, thereby stimulating the development of promising novel technological solutions. Also, our data could underline the value of the competition as a benchmark, highlighting remaining usability limitations or technology adoption hurdles.

Field Defects

Post-chiasmatic damage to the visual system leads to homonymous visual field defects (HVDs), which can severely interfere with daily life activities. Visual Restitution Training (VRT) can recover parts of the affected visual field in patients with chronic HVDs, but training outcome is variable. An untested hypothesis suggests that training potential may be largest in regions with ‘neural reserve’, where cortical responses to visual stimulation do not lead to visual awareness as assessed by Humphrey perimetry—a standard behavioural visual field test. Here, we tested this hypothesis in a sample of twenty-seven hemianopic stroke patients, who participated in an assiduous 80-hour VRT program. For each patient, we collected Humphrey perimetry and wide-field fMRI-based retinotopic mapping data prior to training. In addition, we used Goal Attainment Scaling to assess whether personal activities in daily living improved. After training, we assessed with a second Humphrey perimetry measurement whether the visual field was improved and evaluated which personal goals were attained. Confirming the hypothesis, we found significantly larger improvements of visual sensitivity at field locations with neural reserve. These visual field improvements implicated both regions in primary visual cortex and higher order visual areas. In addition, improvement in daily life activities correlated with the extent of visual field enlargement but not sensitivity gain. Our findings are an important step toward understanding the mechanisms of visual restitution as well as predicting training efficacy in stroke patients with chronic hemianopia.

<p class="Abstrak">Pada tahun 2013, prevelansi penderita stroke di Indonesia sebesar 12,1 % serta merupakan penyebab kematian kedua dan penyebab disabilitas ketiga di dunia. Di Indonesia, angka kontribusi proporsional <em>disability-adjusted life-years</em> (DALYs) dari stroke sekitar 9,7 % dan merupakan penyebab disabilitas nomor satu. Penderita yang mengalami disabilitas akan kesulitan melakukan aktivitas sehari-hari, terutama berkomunikasi. Oleh karena itu perlu dikembangkan alat bantu komunikasi yang dapat membantu penderita pascastroke berkomunikasi sehari-hari dengan memanfaatkan gerakan telapak tangan. Pada penelitian ini digunakan empat buah <em>flex sensor</em> yang diletakkan pada jari telunjuk, tengah, manis, dan kelingking serta satu sensor 3-<em>axis</em> <em>gyroscope</em> MPU6050. Alat bantu komunikasi untuk penderita pascastroke ini telah berfungsi untuk mendeteksi tujuh gerakan dasar, yaitu: “Ya”, “Tidak”, “Saya mau pergi kesana”, “Jam berapa sekarang?”, “Saya mau makan”, “Saya mau minum”, dan “Halo!”. Ketujuh kata atau kalimat tersebut juga ditampilkan di sebuah <em>display</em>. Pendeteksian ketujuh gerakan ini diperoleh dari tekukan empat jari yang dideteksi menggunakan <em>flex sensor</em> dan posisi tangan di arah 3 sumbu (x, y, dan z) menggunakan <em>gyroscope</em> yang diletakkan pada sebuah sarung tangan. Alat ini diharapkan dapat menjadi awal dalam pengembangan alat bantu komunikasi untuk penderita.</p><p class="Abstrak"> </p><p class="Abstract"><strong>Abstract</strong></p><p class="Abstract"><em>In 2013, prevalence of stroke in Indonesia is 12.1% and the second leading cause of deaths and the third most common cause of disability in the world.

Patients with disabilities will have difficulty for performing daily life activities, especially communicating with other people. Therefore, it is necessary to develop communication assistive device that can help post-stroke patients to communicate using their palm. Four flex sensors mounted on the index, middle, ring, and pinky fingers; and one 3-axis gyroscope MPU6050 sensor. This communication asisstive device has fully function to detect seven basic movement for daily life communication, that is: "Yes", "No", "I want to go there", "What time is it?", "I want to eat", "I want to drink" and "Hello!". The seven words / sentences also appear on the viewer screen. The detection of these seven motions is obtained from the four flex sensors and the position of the hand in the 3-axes (x, y, and z) direction from gyroscope that is placed on a glove. This research is a preliminary research in the area of assistive device technology for post-stroke patients.</em></p>

BACKGROUND Dementia is a general term for various disorders characterized by memory impairment and loss of at least one cognitive domain. People with dementia are faced with different difficulties in their daily life activities (DLA). With the use of modern technologies, such as mobile phone apps – often called health apps, their difficulties can be alleviated. OBJECTIVE The aim of this paper was to systematically search, analyze and synthetize mobile phone apps designed to support people with mild dementia in daily life activities in two apps bases: Apple App Store and Google Play Store. METHODS A search was conducted in May 2019 following PRISMA recommendations. Results were analyzed and displayed as tables and graphs. Results were synthetized using thematic analysis which was conducted from 14 components, based on human needs for categorized nursing activities. Mobile phone apps were assessed for quality using the System Usability Scale. RESULTS A total of 15 mobile phone apps were identified applying inclusion and exclusion criteria. Five major themes were identified with thematic analysis: multi-component DLA, communication and feelings, recreation, eating and drinking, and movement. Most of the apps (73%) of the apps were not mentioned in scientific literature. CONCLUSIONS There are many mobile phone apps available in mobile phone markets for the support for people with mild dementia; yet only a few of them are focused on challenges in daily life activities. Most of the available apps were not evaluated nor assessed for quality.
