Virtual and augmented reality applications to improve older adults’ quality of life: A systematic mapping review and future directions

Objective

The use of virtual reality and augmented reality to improve older adults’ quality of life has rapidly increased in recent years. This systematic mapping review aimed to provide a comprehensive overview of existing research that identifies and classifies current virtual reality and augmented reality applications that enhance the quality of life of older adults to increase the understanding of the impact of these technologies.

Methods

To reach this objective, a systematic mapping review was conducted of the studies published between 2009 and 2020 in major scientific databases, such as IEEE Xplore, Web of Science, Scopus, and PubMed. A total of 57 studies were analyzed and classified into four main quality of life domains: physical, cognitive, psychological, and social well-being.

Results

The findings showed that virtual reality and augmented reality have found their places in many quality of life studies of older adults. Although virtual reality and augmented reality applications are notably growing in the physical and cognitive well-being domains in training and rehabilitation settings, they are still in the early stages of development in psychological and social well-being research as well as healthcare settings. Our findings also revealed that virtual reality games, particularly motion-based exergames, and 3D augmented reality systems are the most common virtual reality and augmented reality types among the reviewed studies. Moreover, balance and attention were the most prevalent physical and cognitive functions when using motion-based and immersive virtual reality exergames and augmented reality systems and games, respectively, while confidence and interaction were the most dominant psychological and social functions.

Conclusion

This mapping review provides a comprehensive overview of potential areas for further research in this field, thereby assisting researchers, technologists, and health practitioners in expanding this field of research.

Characteristics of Physical Exercise Programs for Older Adults in Latin America: A Systematic Review of Randomized Controlled Trials

AIM

To characterize physical exercise programs for older adults in Latin America.

METHODS

This review was conducted in accordance with the PRISMA statement. A search for randomized controlled trials (RCTs) published between the years 2015 and 2020 was performed in the Scopus, MedLine and SciELO databases.

RESULTS

A total of 101 RCTs were included. A large percentage of the studies had an unclear risk of bias in the items: selection, performance, detection and attribution. Furthermore, a heterogeneous level of compliance was observed in the CERT items. A total sample of 5013 older adults (79% women) was included. 97% of the studies included older adults between 60-70 years, presenting an adherence to the interventions of 86%. The studies were mainly carried out in older adults with cardiometabolic diseases. Only 44% of the studies detailed information regarding the place of intervention; of these studies, 61% developed their interventions in university facilities. The interventions were mainly based on therapeutic physical exercise (89% of the articles), with a duration of 2-6 months (95% of the articles) and a frequency of 2-3 times a week (95% of the articles) with sessions of 30-60 min (94% of the articles) led by sports science professionals (51% of the articles). The components of physical fitness that were exercised the most were muscular strength (77% of the articles) and cardiorespiratory fitness (47% of the articles). Furthermore, only 48% of the studies included a warm-up stage and 34% of the studies included a cool-down stage.

CONCLUSIONS

This systematic review characterized the physical exercise programs in older adults in Latin America, as well the most frequently used outcome measures and instruments, by summarizing available evidence derived from RCTs. The results will be useful for prescribing future physical exercise programs in older adults.

Effects of Interactive Videogames on Postural Control and Risk of Fall Outcomes in Frail and Pre-frail Older Adults: A Systematic Review and Meta-Analysis

Background: Interactive videogames (IVGs) have been used to reduce risk of falls in the older adult and improve postural control (PC) outcomes. Objective: To systematically review trials that examine whether IVGs training is effective in improving PC and managing falls in frail and pre-frail older adults. Data Sources: Four databases were searched, Scopus, Web of science, PubMed, and MEDLINE, from January 2007 to March 2019. Eligibility Criteria: Frail and pre-frail older adults aged 65+. Interventions were any Nintendo^® Wii™ training. The outcome measures were PC and risk of falls as measured by any validated outcome measure. Studies Appraisal Method: The PEDro (Physiotherapy Evidence Database) scale and Cochrane risk-of-bias tool were used by two independent authors. Results: Eleven papers were included, involving 388 participants, with a mean age of 79 ± 5.7 years. The mean duration of IVGs sessions was 8.8 ± 3.8 weeks, the mean total number of sessions was 20 ± 11.1 session, and the mean length of training was 44 ± 15.7 minutes. Meta-Analysis: IVGs achieved better results compared with traditional exercises and control on the Berg Balance Scale (mean difference [MD] 2.80; 95% confidence interval [CI] 1.21 to 4.39; P < 0.001; I² = 16%), as well as in the short term on Timed Up and Go (MD -1.23; 95% CI -2.37 to -0.09; P = 0.03; I² = 0%). Limitation: Definitive judgement could not be made due to the variability in training, training duration and outcomes measurement. Conclusion: IVGs is a promising modality that has a positive effect on PC but not on the outcome of falls, so it should be prescribed with caution among frail older adults. Systematic Review Registration: PROSPERO registration number: CRD42019129611.

The Effectiveness of Virtual Reality Rehabilitation in Patients with Knee and Hip Osteoarthritis

Osteoarthritis (OA) is a common health problem leading to pain, limitation in physical function, a decrease in the quality of life and disability. OA affects 60-70% of the population above 65 years of age all over the world, and is associated with a high cost of healthcare. The main method of treatment of OA, apart from pharmacotherapy and surgery, is comprehensive rehabilitation. Advances in medical technology have resulted in the possibility of using computer-assisted interventions in rehabilitation. The present narrative review is aimed at investigating the effectiveness of virtual reality (VR) in the rehabilitation of elderly patients with knee or hip osteoarthritis, including patients after arthroplasty. This literature review based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was carried out in five databases: PubMed, Medline, Web of Science, Scopus and PEDro. It includes ten randomized controlled trials focused on the application of games and biofeedback in the rehabilitation of patients with knee and hip osteoarthritis. There are no conclusive reports that interventions based on VR are more effective than standard physical therapy. Moreover, evidence regarding patients after total hip arthroplasty (THA) is very scarce. The effectiveness of VR-based rehabilitation is unclear, although interventions based on VR are promising in view of pain management, postural and proprioception training. However, this evidence is not sufficient to create clinical guidelines and further high-quality studies are needed.
