Exergaming to Increase Physical Activity in Older Adults: Feasibility and Practical Implications

PURPOSE OF REVIEW

To evaluate the feasibility of exergaming among older adults, focusing on acceptability, demand, implementation, and practicality. Additionally, to offer practical implications based on the review's findings.

RECENT FINDINGS

Exergaming is a safe for older adults, potentially increasing physical activity, balance, cognition, and mood. Despite these possible benefits, barriers such as unfamiliarity with equipment, complex controls, and unclear instructions may challenge older adults in exergaming. Based on the experience of older adults, they found exergaming enjoyable, particularly the social interactions. Exergaming was perceived as physically and cognitively demanding, with technical and safety challenges. Introducing exergaming requires thorough familiarization, including written and video instructions, follow-up support, and home accessibility. To be able to follow improvements during exergaming as well as age-appropriate challenges are important for successful integration into daily life. Based on these findings, an ExerGameFlow model for older adults was developed which provides practical implications for future design of exergames and interventions.

Salient Targets and Fear of Falling Changed the Gait Pattern and Joint Kinematic of Older Adults

BACKGROUND

Fear of falling and environmental barriers in the home are two major factors that cause the incidence of falling. Poor visibility at night is one of the key environmental barriers that contribute to falls among older adult residents. Ensuring their visual perception of the surroundings, therefore, becomes vital to prevent falling injuries. However, there are limited works in the literature investigating the impact of the visibility of the target on older adults' walking destinations and how that impact differs across them with different levels of fear of falling.

OBJECTIVE

The purpose of the study was to examine the effects of target salience on older adults' walking performance and investigate whether older adults with varying levels of fear of falling behave differently.

METHODS

The salient target was constructed with LED strips around the destination of walking. Fifteen older adults (aged 75 years old and above), seven with low fear of falling and eight with high fear of falling, volunteered for the study. Participants walked from the designated origin (i.e., near their beds) to the destination (i.e., near the bathroom entrance), with the target turned on or off around the destination of the walking trials. Spatiotemporal gait variables and lower-body kinematics were recorded by inertial sensors and compared by using analysis of variance methods.

RESULTS

Data from inertial sensors showed that a more salient target at the destination increased older adults' gait speed and improved their walking stability. These changes were accompanied by less hip flexion at heel strikes and toe offs during walking. In addition, older adults with low fear of falling showed more substantial lower-body posture adjustments with the salient target presented in the environment.

CONCLUSIONS

Older adults with a low fear of falling can potentially benefit from a more salient target at their walking destination, whereas those with a high fear of falling were advised to implement a more straightforward falling intervention in their living areas.

Efficacy of Interventions Based on the Use of Information and Communication Technologies for the Promotion of Active Aging

Nowadays, the study of how new media and technologies can be used to carry out health education by bringing these tools closer to the elderly population is interesting. It is a way of offering them access not only to greater knowledge, but to greater communication and relationship with their surroundings, a range of new possibilities and resources at their disposal that also represent a way to reduce the generation gap and bring them closer to the rest of the community. Objectives: to evaluate and analyze the studies that show the efficacy of interventions based on the use of information and communication technologies for the promotion of active aging in people older than or equal to 65 years who live in the community. Data sources, study eligibility criteria: the search for the articles was carried out from January 2012 to March 2021, in 6 databases (Pubmed, Cochrane Library, Scopus, Scielo, Google Academic and WOS) based on the clinical question, using the keywords derived from the DeCS and MeSH thesauri, combined with the Boolean operators “AND”, “NOT” and “OR”. The search was limited to publications from the last 9 years, in English and Spanish. Results: after applying the selection criteria and evaluating the quality of the methodology, 7.91% (n = 17) of the 215 results were included with filters: 7 systematic review, 5 of Cohorts and 5 of Randomized Controlled Trial. Conclusions and implications of key findings: the use of communication technologies reduces the feeling of loneliness, as well as the use of virtual reality to exercise, train memory or perform rehabilitation. The most difficult barrier to overcome is the prior ignorance of the majority of the elderly to the technology that is overcome by working as a team throughout the community, especially in the health and educational sector, as well as the family or social nucleus.

Digital Health Promotion and Prevention in Settings: Scoping Review

BACKGROUND

Digital technologies are increasingly integrating into people's daily living environments such as schools, sport clubs, and health care facilities. These settings play a crucial role for health promotion and prevention because they affect the health of their members, as the World Health Organization has declared. Implementing digital health promotion and prevention in settings offers the opportunity to reach specific target groups, lower the costs of implementation, and improve the health of the population. Currently, there is a lack of scientific evidence that reviews the research on digital health promotion and prevention in settings.

OBJECTIVE

This scoping review aims to provide an overview of research targeting digital health promotion and primary prevention in settings. It assesses the range of scientific literature regarding outcomes such as applied technology, targeted setting, and area of health promotion or prevention, as well as identifies research gaps.

METHODS

The scoping review was conducted following the Levac, Colquhoun, and O'Brien framework. We searched scientific databases and gray literature for articles on digital setting-based health promotion and prevention published from 2010 to January 2020. We included empirical and nonempirical publications in English or German and excluded secondary or tertiary prevention and health promotion at the workplace.

RESULTS

From 8888 records, the search resulted in 200 (2.25%) included publications. We identified a huge diversity of literature regarding digital setting-based health promotion and prevention. The variety of technology types extends from computer- and web-based programs to mobile devices (eg, smartphone apps) and telemonitoring devices (sensors). We found analog, digital, and blended settings in which digital health promotion and prevention takes place. The most frequent analog settings were schools (39/200, 19.5%) and neighborhoods or communities (24/200, 12%). Social media apps were also included because in some studies they were defined as a (digital) setting. They accounted for 31.5% (63/200) of the identified settings. The most commonly focused areas of health promotion and prevention were physical activity (81/200, 40.5%), nutrition (45/200, 22.5%), and sexual health (34/200, 17%). Most of the interventions combined several health promotion or prevention methods, including environmental change; providing information, social support, training, or incentives; and monitoring. Finally, we found that the articles mostly reported on behavioral rather than structural health promotion and prevention.

CONCLUSIONS

The research field of digital health promotion and prevention in settings is heterogeneous. At the same time, we identified research gaps regarding the absence of valid definitions of relevant terms (eg, digital settings) and the lack of literature on structural health promotion and prevention in settings. Therefore, it remains unclear how digital technologies can contribute to structural (or organizational) changes in settings. More research is needed to successfully implement digital technologies to achieve health promotion and prevention in settings.

Methodological Quality of User-Centered Usability Evaluation of Ambient Assisted Living Solutions: A Systematic Literature Review

This study aimed to determine the methodological quality of user-centered usability evaluation of Ambient Assisted Living (AAL) solutions by (i) identifying the characteristics of the AAL studies reporting on user-centered usability evaluation, (ii) systematizing the methods, procedures and instruments being used, and (iii) verifying if there is evidence of a common understanding on methods, procedures, and instruments for user-centered usability evaluation. An electronic search was conducted on Web of Science, Scopus, and IEEE Xplore databases, combining relevant keywords. Then, titles and abstracts were screened against inclusion and exclusion criteria, and the full texts of the eligible studies were retrieved and screened for inclusion. A total of 44 studies were included. The results show a great heterogeneity of methods, procedures, and instruments to evaluate the usability of AAL solutions and, in general, the researchers fail to consider and report relevant methodological aspects. Guidelines and instruments to assess the quality of the studies might help improving the experimental design and reporting of studies on user-centered usability evaluation of AAL solutions.

Use of Virtual Reality Technology to Support the Home Modification Process: A Scoping Review

Healthcare is a field in which the benefits of virtual reality (VR), such as risk-taking without consequences, direct experience, and service outcome prediction, can be utilized. VR technology has been used to help clients face environmental barriers by implementing a home environment in virtual reality without a home visit by an expert. This scoping review was conducted to identify the areas and implementation methods of the home modification process supported by VR technology. Twelve studies met the research criteria. The following three types of tools supported by VR technology for the home modification process were identified: educational tools for clients or specialists, home environment measurement tools, and intermediaries for decision making and collaboration between clients and specialists. Most of the studies reported positive results regarding the usability and acceptability of the technology, but barriers have also been reported, such as technical problems, inappropriate population groups for technical use, cost-related issues, the need for training, and fear that the technology could replace home visits. Thus, VR technology has potential value in the home modification process. However, for future clinical applications, additional studies to maximize the benefits of these VR technologies and address the identified problems are required.

Occupational Therapy and the Use of Technology on Older Adult Fall Prevention: A Scoping Review

Introduction: Falls are the second leading cause of accidental or non-intentional deaths worldwide and are the most common problem as people age. The primary purpose of addressing falls is to detect, prevent, treat, and reduce their incidence and consequences. Previous studies identified that multifactorial programs, an interprofessional team, and assistive technology are required to address falls in older adults effectively. Accordingly, the research question is as follows: what are the scope, type of studies, and approaches and strategies to fall risk using technology in the existing occupational therapy literature regarding interventions to address the effects of falls in older adults on daily living? Methods: This scoping review was carried out in January 2020 through Biblioteca Virtual de Salud España, C.I.N.A.H.L., Cochrane Plus, OTSeeker, PubMed, Scopus, and Web of Science. Results: Twelve papers were included. We analyzed the year and journal of publication, authors' affiliation, and design of the study, and thematic categories. There were three themes: participants' characteristics, type of intervention, and fall approach and type of technology used. Discussion and Conclusions: The literature obtained is scarce. It is considered to still be an emerging theme, especially when considering the use of technology for occupational therapy.

Using Serious Games to Increase Prevention and Self-Management of Chemotherapy-Induced Nausea and Vomiting in Older Adults With Cancer

OBJECTIVES

To examine the frequency and types of preventive and self-management behaviors reported by participants, as well as report acceptability and usability data for the electronic Symptom Self-Management Training-Chemotherapy-Induced Nausea and Vomiting (CINV) serious game.

SAMPLE & SETTING

80 adults who were aged 60 years or older and newly diagnosed with cancer were recruited from a community cancer center.

METHODS & VARIABLES

Participants were randomized to an intervention or control group. A symptom management checklist was used to record preventive and self-management behaviors used after each chemotherapy treatment at home. Acceptability and usability were assessed using a brief survey.

RESULTS

The intervention group reported using more preventive behaviors, and the control group reported using more self-management behaviors. Antiemetics were the most common strategy used, followed by dietary strategies. Participants rated all aspects of the serious game highly for usability and acceptability.

IMPLICATIONS FOR NURSING

Oncology providers can help older adults plan for self-managing treatment-related side effects at home. Recording self-management behaviors may reinforce the importance of active prevention and management of CINV.

Usability Issues of Clinical and Research Applications of Virtual Reality in Older People: A Systematic Review

Aging is a condition that may be characterized by a decline in physical, sensory, and mental capacities, while increased morbidity and multimorbidity may be associated with disability. A wide range of clinical conditions (e.g., frailty, mild cognitive impairment, metabolic syndrome) and age-related diseases (e.g., Alzheimer's and Parkinson's disease, cancer, sarcopenia, cardiovascular and respiratory diseases) affect older people. Virtual reality (VR) is a novel and promising tool for assessment and rehabilitation in older people. Usability is a crucial factor that must be considered when designing virtual systems for medicine. We conducted a systematic review with Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) guidelines concerning the usability of VR clinical systems in aging and provided suggestions to structure usability piloting. Findings show that different populations of older people have been recruited to mainly assess usability of non-immersive VR, with particular attention paid to motor/physical rehabilitation. Mixed approach (qualitative and quantitative tools together) is the preferred methodology; technology acceptance models are the most applied theoretical frameworks, however senior adapted models are the best within this context. Despite minor interaction issues and bugs, virtual systems are rated as usable and feasible. We encourage usability and user experience pilot studies to ameliorate interaction and improve acceptance and use of VR clinical applications in older people with the aid of suggestions (VR-USOP) provided by our analysis.
