Background: Executive function (EF) deficits are a significant risk factor for falls among older adults (OAs). However, relationship between EF subdomains (shifting, updating, and inhibition), postural balance (PB), and fall risk in healthy OAs, remains poorly understood. Objective: This study aimed to investigate the relationship between EF subdomains (shifting, updating, and inhibition) and PB, and to assess their impact on risk of falls in community-dwelling OAs. Methods: A cross-sectional study involving 50 OAs aged over 60 years (average age of 72 years) was conducted. Participants underwent assessments of EF subdomains and PB using validated tests. A correlation analysis was employed to examine the relationships between EF and PB. Results: The study revealed significant correlations between subdomains and PB. Mental set shifting (r = −.539; p < .001) and inhibition (r = −.395; p = .050) exhibited inverse relationships with PB. Stepwise multiple linear regression showed that Trail Making Test Part B was associated with the PB (R2 = .42, p < .001). Conclusion: These findings highlight the importance of assessing EF subdomains, particularly shifting and inhibition, to identify risk of falls. Trail Making Test Part B largely explains the variability of the PB. Integrating PB assessments and EF training, such as the Mini-BESTest, into routine care can be vital for fall prevention strategies. Significance/Implications: This knowledge underscores the need for cognitive training interventions focusing on shifting and inhibition to enhance PB and potentially reduce falls. Additionally, incorporation of EF assessment tools as Trail Making Test Part B and the Mini-BESTest into routine clinical practice for community-dwelling OAs is recommended to address fall prevention strategies.

Physical computing is a field that involves the use of sensors, actuators, and microcontrollers to build systems that interact with the environment. This approach has been used in education, particularly to teach computer science, programming, computational thinking, and design concepts. This systematic review explores the use of physical computing in K-12 education, with a focus on what educational interventions are like, how they are assessed, their effects, and how students experience them. We included 43 scientific studies that describe the methodology and assessment process used in the intervention. We found that physical computing interventions have three types of expected educational outcomes: to learn physical computing itself, to improve other learning outcomes, or to improve attitudinal variables. The interventions use a variety of educational methods to achieve their goals; as well as a variety of instruments to measure outcomes. A common lesson structure has emerged, widely adopted across classrooms, including a short lecture followed by a hands-on phase, usually including teamwork to foster collaboration. Further comparative and long-term studies are needed to understand how physical computing interventions affect students, especially those who are underrepresented.

Aphasia, an alteration in the ability to use language, is a common consequence of stroke. Aphasia is treated by multidisciplinary teams including speech and language therapists. However, due to high workload and scarce resources, patients may not get enough therapy time. This article proposes MyAphasia, an application to help speech and language therapists in the treatment of aphasia in the acute phase, by assigning activities for the patient to perform independently. The application was evaluated by 11 speech and language therapists for 2 days. The results are promising: therapists found MyAphasia easy to use and helpful, potentially saving time and resources.

Background: Chronic pain affects millions worldwide, influenced by biological, psychological, and social factors. Catastrophizing predicts chronic pain outcomes, increased pain intensity, and worsening recovery. Virtual reality (VR) interventions offer innovative pain management strategies, but their effects on catastrophizing remain unclear. Methods: This systematic review and meta-analysis followed the PRISMA guidelines. Studies involving adults with chronic musculoskeletal pain, VR-based interventions, and randomized controlled trials were included. The primary outcome was pain catastrophizing. Searches were conducted in PubMed, CINAHL, Scopus, WoS, and PEDro until May 2025. The risk of bias was assessed using Cochrane RoB-2. Meta-analysis calculated effect sizes using mean differences (MD) and standardized mean differences (SMD) with fixed and randomized-effects models. Results: Of 306 records, 244 were screened, 19 underwent full-text review, and two additional studies were identified via Google Scholar. Nine studies were included, eight of which were meta-analyzed. The interventions included eight immersive and one non-immersive VR studies, lasting 3 to 12 weeks. A small but statistically significant effect was found when comparing VR-based interventions with controls (SMD = −0.26 [−0.48; −0.04]). Psycho-cognitive VR-based interventions had a significant effect (SMD = −0.32 [−0.56; −0.09]), while exercise-based VR did not (MD = −0.11 [−4.36; 4.14]). Immersive VR showed a small but significant effect when compared to non-intervention or sham controls (SMD = −0.37 [−0.75; −0.00]). However, when compared to all types of comparators, the effect was not statistically significant (SMD = −0.25 [−0.51 to −0.00]). Heterogeneity was moderate and not significant (p > 0.05). Conclusions: VR-based interventions, particularly immersive with psycho-cognitive approaches, show potential in reducing pain catastrophizing. Future randomized trials are needed to elucidate VR’s efficacy in managing pain catastrophizing.

Informal caregivers provide long-term, unpaid support to patients – usually family or friends – with serious illnesses. Although caregiving is essential, it can have adverse effects, e.g. physical and emotional exhaustion. Digital applications are a cost-effective alternative to manage these effects. However, applications for caregivers are usually centered on skill building and education rather than well-being, and general-purpose stress management applications – besides not specifically considering caregivers – frequently change and do not usually incorporate social aspects. To design a caregiver-centered application, we analyzed caregiver needs, specifically focusing on well-being aspects. We present Care4Plant, an application designed to measure the emotional dimension of caregivers’ burden based on the Zarit Burden Questionnaire, and suggest a set of mood improvement tasks accordingly. Care4Plant features a virtual plant that represents informal caregivers’ emotional well-being, allowing them to care for the plant through actions intended to manage their mental health and reduce stress, and to share their plant with other caregivers through a social network represented by a greenhouse. We conducted an evaluation of Care4Plant with nine users over two weeks. The results indicated good levels of usability and demonstrated that the approach of motivating users through the virtual plant was well-received.

Background The worldwide population over 60 years of age is increasing. Thus, older adults should maintain interest and participate in social and family activities to help preserve their independence and promote their well-being. Well-being is a part of human health in its most general sense which manifests itself in all areas of human activity. Leisure activities such as listening to an audiobook may provide enjoyment and promote relaxation in older people and help improve the well-being of older adults. Objective This study aims to investigate the impact of an audiobook mobile application on the well-being perception of older adults and to evaluate the usability of a mobile application specifically designed for this population. Methods This protocol is a quasi-experimental study that will be conducted with 60 older adults who will use an audiobook mobile application for 4 weeks. Participants will be evaluated pre and post intervention through validated questionnaires on digital competences, usability, and perception of well-being. Results A positive impact on the perception of well-being is expected in older adults who listen to poems through an audiobook mobile application. Conclusions This study will allow us to know the impact on the perception of the older adult’s well-being and stimulate other groups to do research on other populations and literary genres.

Diary studies are used to gather user information in their natural context. Despite the advantages of digital diaries, older users are not able to fully beneft from them, e.g. due to decreased motor and cognitive abilities, and low digital skills. This work presents InMyDay, a digital diary application specifcally designed and implemented for older users. The goal of this work is twofold: frst, we research whether older users are able to record activities and refect on their emotions using a digital diary. Then, using the results of this frst phase, we implemented three input styles for the second version of the digital diary: voice, stylus, and keyboard. Overall, 23 older users participated in evaluations aimed at improving the design of the diary and understanding their input style preferences. We found that the older adults used the diary to refect on their emotions, registering positive as well as negative emotions. We also found that the variety of choices in input styles helped the participants select the option most suited to their particular needs and preferences. Future work will focus on evaluating the digital diary over a longer period of time, to analyze variables such as long-term adoption and motivation, as well as trends in the selection of input styles.

Technology can improve university students’ communication, helping them maintain relationships. Although there are many available technological tools, students face challenges—e.g., living far from home, failing grades, depression—that may isolate them from their networks. Most research into these topics has been conducted in countries in which students leave their parents’ home while at university, which is not the case for most students in southern Chile. In this context that has been seldom studied, this paper presents two studies, focusing on two research questions: (1) How do university students in southern Chile communicate? (2) Can a mobile application persuade university students to increase their communication patterns? To answer these questions, we conducted a survey with 90 students in southern Chile, and then developed a persuasive application called Social+Me, aimed at monitoring communication with students’ support networks and persuading them to keep in touch. We conducted a preliminary evaluation of Social+Me, and the application was well received by participants, who felt that it improved their communication with their social network. The main impact of our study lies in applying persuasive technologies to the communicative practice of university students to prevent students from feeling isolated or unsupported.

Balance is affected in numerous neurologic disorders, like stroke, multiple sclerosis and Parkinson’s disease contributing to falls, and diminishing quality of life and functionality. The mini-BESTest is one of the most recommended scales to detect balance disorders in people with Parkinson’s disease, which has solid psychometric properties. Unfortunately, this scale has not been validated in Chile and there are no other validated scales that can determine balance disorders in patients with Parkinson’s disease to date. The study objective was to validate the mini-BESTest scale in Chilean Parkinson’s disease patients. The translation and adaptation to Chilean Spanish of the mini-BESTest scale were made following a cross-cultural adaptation process, to then obtain face and content validity by an expert committee. Afterwards, the demographic data and psychometric properties of internal consistency and ceiling and floor effects were measured with a sample of 50 subjects with Parkinson’s disease. Furthermore, 10 subjects of the sample were evaluated with the purpose of measuring inter rater reliability. The scale presented a good internal consistency (Cronbach’s alpha = 0.845), and an excellent inter rater reliability (intraclass correlation coefficient = 0.97), no ceiling or floor effects were found. The results of the face and content validity and psychometric properties are adequate, achieving the validation of the mini-BESTest scale for balance in Chilean people with Parkinson’s disease.

Aging is associated with a progressive decline in health, resulting in increased medical care and costs. Mobile technology may facilitate health self-management, thus increasing the quality of care and reducing costs. Although the development of technology offers opportunities in monitoring the health of older adults, it is not clear whether these technologies allow older adults to manage their health data themselves. This paper presents a review of the literature on mobile health technologies for older adults, focusing on whether these technologies enable the visualization of monitored data and the self-reporting of additional information by the older adults. The systematic search considered studies published between 2009 and 2019 in five online databases. We screened 609 articles and identified 95 that met our inclusion and exclusion criteria. Smartphones and tablets are the most frequently reported technology for older adults to enter additional data to the one that is monitored automatically. The recorded information is displayed on the monitoring device and screens of external devices such as computers. Future designs of mobile health technology should allow older users to enter additional information and visualize data; this could enable them to understand their own data as well as improve their experience with technology.
