The effectiveness of virtual reality training in reducing the risk of falls among elderly people

Somatosensory game intervention experience among prefrail older adults in the community: A qualitative study

BACKGROUND

Somatosensory game interventions have been used to rehabilitate hospitalized older adults. However, their application in prefrail older adults in the community is poorly understood, hindering the development of effective intervention strategies and exercise diversification.

OBJECTIVES

This study aimed to explore the experiences of prefrail Chinese older adults engaging in somatosensory gaming interventions and thus develop tailored intervention frameworks and support strategies.

METHODS

We conducted semistructured interviews with 12 prefrail older adults who participated in a 12-week sensory game intervention study from August to September 2022. The interviews were analyzed using Nvivo 11.0 software following Colaizzi's seven-step analysis method.

RESULTS

Somatosensory game intervention experiences were classified into four main themes and 11 subthemes: health intervention effects (enhanced limb muscle strength, improved reaction capacity, alleviated negative emotions), positive experiences (enhanced self-achievement, increased exercise motivation, elevated social engagement), negative experiences (frustration from unmet score expectations, initial discomfort), and intervention requirements (sustained interventions, technical support, personalized content).

CONCLUSION

The findings have implications for somatosensory game interventions targeting prefrail older adults in the community.

Application progress of exergames in health interventions for the elderly

With the aging population in China, health issues among the elderly are becoming increasingly prominent, leading to a rapidly growing demand for health interventions for the elderly. Exergames are one of the important emerging methods in the field of health interventions for the elderly, widely used and yielding positive results. While research on exergames is well-established abroad, it is still in its infancy in China, lacking reports on the types, interaction forms, intervention content, application status, and effectiveness of exergames. Exergames are suitable for widespread use among the elderly in China, and there is a need to accelerate the development and application of exergames in the field of health interventions for the elderly in China.

Motion tracking virtual reality technology in improving gait in the elderly: A randomized controlled trial

OBJECTIVE

This study aimed to assess the effectiveness of virtual reality-based treadmill training on gait performance and tolerance in the elderly.

DESIGN

Two-armed randomized controlled trial.

SETTING

The Medical Rehabilitation Sciences Department, Umm Al Qura University, Saudi Arabia.

PARTICIPANTS

Sixty Saudi elderly of both sexes, aged 65-75 years, were included.

INTERVENTIONS

Participants were divided into two groups. The control group received treadmill training without virtual reality, alongside a conventional exercise program. The experimental group received a training program that was similar to the control group's exercises but with C-Mill virtual reality treadmill training. The program lasted one hour, three times per week, over four consecutive weeks.

MAIN MEASURES

The study assessed changes in outcome measures at baseline, Post-1 (after four weeks of training), and Post-2 (four weeks post-training). These measures encompassed the primary outcome, the 6-minute walk test (meter), as well as secondary outcomes such as stride length (meter), stride time (second), cadence (steps/minute), and velocity (meter/second). These parameters were evaluated using the GaitRite electronic gait analysis walkway.

RESULTS

The experimental group showed better improvement in the mean values of the 6-minute walk test, stride length, stride time, cadence, and velocity compared to the control group at post-1 and post-2. The P-values were respectively at post-1 (0.019, 0.015, 0.041, 0.013, and 0.021) and (0.011, 0.025, 0.073, 0.061, and 0.017) at post-2 (all, P < .05).

CONCLUSIONS

C-Mill virtual reality treadmill training shows potential in improving gait parameters and walking tolerance in the elderly in Saudi Arabia.

The Application of Virtual Reality in Shoulder Surgery Rehabilitation

To achieve a positive functional prognosis in orthopedic surgery, particularly in shoulder surgeries, effective rehabilitation is essential. Recently, there has been growing interest in the use of virtual reality (VR) in the field of orthopedics, particularly for preoperative education and training, as well as clinical and home-based rehabilitation. This report describes the process of developing an application utilizing Meta Quest 2 VR technology (Meta, CA, USA) for rehabilitation after shoulder surgery. This application assists patients in performing postoperative exercises at home by wearing VR equipment tailored to their postoperative weeks. The advantages of VR rehabilitation lie in overcoming the limitations of traditional rehabilitation methods and providing patients with a better rehabilitation experience. Moreover, automating the rehabilitation process and reducing patients' visits to clinics can lead to cost savings. This report raises expectations for the potential and scalability of VR utilization, extending beyond orthopedics to other fields. In addition, it anticipates that with better feedback and motivation, the rehabilitation effects for patients can be further enhanced.

Effects of kinect-based virtual reality training on bone mineral density and fracture risk in postmenopausal women with osteopenia: a randomized controlled trial

Osteopenia is a condition characterized by low bone mineral density (BMD) that increases fracture risk, particularly among postmenopausal women (PMW). This study aimed to determine the effects of Kinect-based VRT on BMD and fracture risk in PMW with osteopenia. The study was a prospective, two-arm, parallel-design, randomized controlled trial. The study enrolled 52 participants, 26 randomly assigned to each group. In the experimental group, Kinect-based VRT was provided thrice weekly for 24 weeks for 45 min/session. Both groups were instructed to engage in a daily 30-min walk outdoors. The fracture risk assessment tool (FRAX) was used to calculate fracture risk, and dual-energy X-ray absorptiometry was used to measure lumbar spine and femur neck BMD. Both variables were assessed at baseline and 24 weeks afterwards. After 24 weeks of Kinect-based VRT, the experimental group showed significant BMD increases in the right and left femoral necks and lumbar spine (p value < 0.001). In the control group, the BMD at the right and left femoral necks showed fewer significant changes (p value < 0.022 and 0.004, respectively). In the control group, lumbar spine BMD did not change (p = 0.57). The experimental group showed significantly lower FRAX scores for hip fracture prediction (HFP) and hip prediction of major osteoporotic (HPMO) at both femoral necks (p value < 0.001) than the control group (p = 0.05 and p = 0.01, respectively), but no significant change at the left femoral neck for HFP (p = 0.66) or HPMO (p = 0.26). These findings indicate that a Kinect-based VRT intervention resulted in significantly increased BMD and a reduced fracture risk, as predicted by HFP and HPMO measurements. These improvements were more pronounced in the experimental group than in the control group. Thus, Kinect-based VRT may be utilized as an effective intervention to improve BMD and reduce fracture risk in postmenopausal women with osteopenia.

Forest therapy using virtual reality in the older population: a systematic review

Introduction

As life expectancy increases, more attention needs to be paid to their mental and physical condition. Many older patients are also bedridden, which makes some treatments, like in vivo exposure to natural environments, more difficult to be applied. This study aimed to systematically review articles that include interventions combining virtual reality and forest environment, targeting a sample of older people.

Methods

Based on PRISMA guidelines, we conducted a literature search in three databases (EBSCO, PubMed, and Scopus), plus gray literature (OpenGrey). We considered only studies that used forest settings via virtual reality and included a sample with age ≥ 65.

Results

After the screening and eligibility stages, 7 articles have been included.

Discussion

The study underlines the need to implement research in this direction to standardize effective procedures that can be used to improve the mental and physical health of the older people and caregivers, while also reducing social costs.

The effects of virtual reality training on postural sway and physical function performance on older women with chronic low back pain: A double-blind randomized clinical trial

BACKGROUND

Chronic low back pain (CLBP) is known as an important debilitating health condition among older women.

OBJECTIVE

This study aimed to evaluate the effects of eight-week virtual reality training (VRT) exercises on postural sway and physical function performance (PFP) among older women suffering from CLBP.

METHODS

Twenty-seven older women presenting with CLBP were randomized into experimental and control groups. The experimental group was instructed to perform 30-minute VRT exercises three times a week for eight weeks. Plantar pressure variables [sway velocity (SV) and anterior-posterior (AP) and medial-lateral (ML) fluctuations of the center of pressure (CoP)], 30-second chair stand test (30CST), and timed up and go (TUG) test were recorded.

RESULTS

The VRT group exhibited significant decreases in SV (p= 0.002), AP (p= 0.008), and ML (p= 0.02) fluctuations. Also, the performance of the VRT group in the 30CST and TUG tests significantly improved after the exercises (P< 0.001).

CONCLUSION

According to the results, VRT and the program used in this study should be used to enhance balance and PFP in older women with CLBP who mostly prefer activities that are accessible and feasible in low-risk environments.

Exploring the Psychological Nexus of Virtual and Augmented Reality on Physical Activity in Older Adults: A Rapid Review

With the global population of older adults projected to double to 2.1 billion by 2050, it becomes crucial to promote healthy aging to alleviate the associated disease burden. In this context, technology, particularly virtual reality (VR) and augmented reality (AR), has garnered attention for its potential to augment physical activity in older adults. These immersive technologies offer interactive and enjoyable exercise experiences, making physical activity more appealing. However, the effectiveness of these interventions is not solely attributed to technology itself but is deeply intertwined with psychological processes. This rapid review examines the effectiveness of VR and AR interventions in enhancing physical exercise among healthy older adults while exploring the role of psychological variables, including mood, self-efficacy, and motivation. The results of the study show that technology-enhanced physical activity interventions hold great promise but call attention to the need for a comprehensive understanding of psychological dynamics that will pave the way for more tailored and effective interventions. Future research endeavors should aim to bridge these gaps in knowledge to optimize the impact of technology on healthy aging.

Effectiveness of virtual reality-based balance and gait in older adults with fear of movement: A systematic review and meta-analysis

OBJECTIVE

To summarize the current evidence from randomized controlled trials (RCTs) regarding the effectiveness of Virtual Reality (VR) training and functional mobility in older adults with fear of movement. TYPE: Systematic review and meta-analysis of randomized clinical trials.

METHODOLOGY

An electronic search was performed using PubMed, Embase, Medline, SPORTDiscus, Scopus, and CINAHL. A data search from January 2015 to December 2022 and a manual electronic literature search were conducted to identify published RCTs. The effectiveness of VR-based balance training for balance and gait was evaluated in older adults with a fear of movement, which was measured by the Timed Up and Go (TUG) test and the Falls Efficacy Scale (FES). Three reviewers independently performed the study selection, and the quality assessment of the included studies was performed using the Physiotherapy Evidence Database (PEDro) scale. The reporting was based on the new Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Guidelines.

SYNTHESIS

The search product produced 345 results, from which 23 full text articles were studied. Seven RCTs of good methodological quality, including 265 participants, were included in the review. Overall, the studies reported that VR had a significant improvement on the TUG (Cohen's d = -0.91 [-1.38; -0.44], p = 0.001), while the FES was not significantly different (Cohen's d = -0.54 [-1.80; 0.71] p = 0.40). The average for PEDro scores (6.14) was good, and the risk of bias revealed that more than one-third of the studies correctly described the random sequence generation and allocation concealment procedures.

CONCLUSION

VR-based training is effective on balance or gait training based on the TUG; however, there were mixed results to improve FES scores following VR intervention. These inconsistent results might be limited due to variations in the studies, including heterogeneous training paradigms, sensitive outcome measures, small sample sizes, and short intervention durations, which limit the validity of our findings. Future investigations should compare different VR protocols to help establish better guidelines for clinicians.

Rehabilitation in Older Adults Affected by Immobility Syndrome, Aided by Virtual Reality Technology: A Narrative Review

Individual mobility deficit in older adults induces a variety of medical conditions, diminishing their functional capacity in pursuing activities of daily living. In immobility syndrome patients, such conditions are prone further deterioration through a drastically reduced scope of physical activity, owing mostly to poor self-motivation and the monotonous character of conventional rehabilitation regimens. As evidenced by published research, virtual reality technology solutions in rehabilitation management actually add significantly to patients' self-motivation, while promoting their active involvement in therapy through visual, auditory, and kinaesthetic stimuli. Effective rehabilitation training aided by virtual reality solutions helps patients acquire specific physical and cognitive skills to be subsequently emulated in the real-world environment. The extra added advantage lies in facilitating such training within patients' own home environments, combined with online monitoring of their progress, when not personally supervised by a physiotherapist, which also boosts the overall cost effectiveness of the therapeutic management itself. This narrative review appears to be the very first one principally focused on critically comparing individual immobilisation with immobility syndrome, especially through the application of the Authors' own substantial hands-on therapeutic experience in managing various rehabilitation schemes, specifically aided by diverse virtual reality technology solutions.

Does Exercising with the Use of Virtual Reality during Haemodialysis Have an Impact on Plasma Levels of Interleukin 1β, Interleukin 6, and Interleukin 8?

Cytokines are a group of fine proteins which play a key role in the regulation of various biological processes, including inflammatory reactions. Proinflammatory cytokines, such as interleukin 1β (IL-1β), interleukin 6 (IL-6), and interleukin 8 (IL-8), are produced in response to various stimuli, including infections, tissue damage, and oxidative stress. Virtual reality (VR) use during intradialytic exercises improves physical activity. The purpose of the study was to evaluate the relationship between exercising regularly with the use of virtual reality during haemodialysis and the levels of selected cytokines (Il-1, Il-6, Il-8). The study and the control groups consisted of end-stage renal disease patients who underwent haemodialysis as a renal replacement treatment. The study group comprised patients subject to haemodialysis as a renal replacement therapy who were to work out with the use of a prototype of the NefroVR system for 20 min when undergoing haemodialysis (HD). Statistical analyses utilised Statistica 13. The conducted research demonstrated that regular exercises with the use of virtual reality might be related to a decrease in inflammation in patients included in the chronic haemodialysis programme. It is key to encourage patients with end-stage renal disease treated with haemodialysis to exercise regularly because of the possibility of their proinflammatory parameters becoming reduced.

The effect of virtual reality technology on anti-fall ability and bone mineral density of the elderly with osteoporosis in an elderly care institution

OBJECTIVE

To explore the impact of virtual reality (VR) training on anti-fall ability and bone mineral density (BMD) among elderly patients admitted to a healthcare institution.

METHODS

People (aged 50) with osteoporosis in an elderly care institution in Anhui Province June 2020 to October 2021 were selected and randomly divided into VR group (n = 25) and control group (n = 25). In VR group, the virtual reality rehabilitation training system was used for training, while control group was treated with traditional fall prevention exercise intervention. The changes of Berg Balance Scale (BBS), timed up and go test (TUGT), functional gait assessment (FGA), bone mineral density (BMD) and falls during 12 months of training were compared between the two groups.

RESULTS

BBS and FGA were positively correlated with BMD of the lumbar vertebrae and femoral neck, and TUGT was negatively correlated with BMD of the lumbar vertebrae and femoral neck. After 12 months of training, the BBS score, TUGT evaluation and FGA evaluation of the two groups were significantly improved compared with those prior to training (P < 0.05). However, there was no significant difference in the lumbar spine and femoral neck BMD between the two groups 6 months after the intervention. The femoral neck and lumbar spine BMD of the VR group improved, and it was significantly higher than that of the control group 12 months after the intervention. Nevertheless, there was no significant difference in terms of the incidence of adverse events between the two groups.

CONCLUSION

VR training can improve anti-fall ability and increase femoral neck and lumbar spine BMD and can effectively prevent and reduce the risk of injury among elderly people with osteoporosis.

Comparing the Effects of Virtual Reality and Home Chair-Based Exercises on Balance, Daily Living Activities, and Loneliness Among Older Adults With Balance Disorders

The current quasi-experimental study aimed to compare the effects of virtual reality (VR) and home chair-based (HCB) exercises on balance, daily living activities, and loneliness among older adults (N = 90) with balance disorders living in nursing homes. Participants were assigned to three groups: (a) VR exercises, (b) HCB exercises, and (c) routine nursing home programs. Findings indicated that VR and HCB exercises significantly increased participants' balance and daily living activities compared to routine programs (p < 0.001). However, there was no clinical difference among groups regarding Berg Balance Scale and Barthel Index scores. Main effect of time regarding loneliness mean score (p = 0.991) was not significant among groups. The minimal detectable change pre-set standard for loneliness also showed no significant clinical difference. Exercise had no significant impact on loneliness; however, it had a positive role in improving balance and daily living activities, with no significant difference between VR and HCB exercises. Further studies are recommended to evaluate adherence to such exercises. [Research in Gerontological Nursing, 16(1), 33-42.].

The effect of six week virtual reality training on the improvement of functional balance in women with type-I osteoporosis: A preliminary study

Purpose

This preliminary study aimed to investigate the effects of exergames in a virtual reality environment to improve functional balance during goal-directed functional tasks in postmenopausal women with osteoporosis.

Methods

Twelve volunteer postmenopausal women with osteoporosis were randomly assigned to virtual reality (VRT, n = 6) and conventional multimodal (CMT, n = 6) training groups. The exercise was performed for 6 weeks, 3 days weekly, and 18 sessions. Using a force platform, functional balance assessments were made through four dynamic tasks, including performance-based limits of stability (LOS), curve tracking (CT), sit-to-stand (STS), and turning before and after 18 sessions of treatment. Each task's time-dependent center of pressure (COP) variables was separately calculated via Kistler-Mars software.

Results

The COP variables of LOS and CT tasks were significantly improved after 6 weeks of CMT and VRT (P ≤ 0.05). In the VRT group, the rising index (P < 0.00), COP sway velocity in STS, and Turn sway were significantly reduced (P < 0.05). Following the VRT, the mean difference of forwarding maximum COP excursion increased (P = 0.03), and errors in CT (P = 0.03) significantly decreased.

Conclusion

The VRT and CMT improved the COP sway parameters during weight-shifting tasks. The VRT was more effective than CMT in increasing the ability to control weight-shifting and dynamic functional tasks in postmenopausal women with osteoporosis. This approach in training has suitable potential to provide convenient error feedback learning.

Exergaming delivery of a balance and fall prevention program for older adults: A feasibility study

Objective

Older adults are at high risk of falls and this problem calls for efficient and scalable interventions. This study investigated whether a motion capture system paired with balance training exergaming software is a feasible strategy to deliver therapeutic exercise to older adults in an aged care facility.

Methods

This study analyzed data from a quality improvement rehabilitation initiative. Two convenience samples of older adults were included: a usual care group (n = 12), admitted to a rehabilitation hospital and receiving standard in-patient therapy 5×/week and the Evolv group (n = 12), admitted to an aged care facility, prescribed exergaming 3×/week. All participants performed 30-minute exercise sessions based on a fall prevention program over 3 months. The Short Physical Performance Battery (SPPB) and Tinetti Performance Oriented Mobility Assessment test were administered pre- and post-treatment.

Results

No adverse events were recorded during the interventions. Mean SPPB increase for Evolv participants was 2.25 ± 1.35 (p < .001, CI for mean = 1.39 to 3.11, d = 1.66), compared with a non-significant change in the usual care group (mean increase = 2.25 ± 3.82, p = .066, CI for mean = -0.18 to 4.68, d = 0.59). Tinetti improvement was significant for the individuals receiving usual care (3.83 ± 2.82, p = .012, CI for mean = 1.01 to 6.66, d = 0.86) but there were no significant between-group differences in outcomes.

Conclusions

Exergaming with the Evolv system for balance and strength training may be a feasible strategy to improve physical function for older adults recovering in an aged care facility.

Immersion Therapy with Head-Mounted Display for Rehabilitation of the Upper Limb after Stroke-Review

Immersive virtual therapy technology is a new method that uses head-mounted displays for rehabilitation purposes. It offers a realistic experience that puts the user in a virtual reality. This new type of therapy is used in the rehabilitation of stroke patients. Many patients after this disease have complications related to the upper extremities that limit independence in their everyday life, which affects the functioning of society. Conventional neurological rehabilitation can be supplemented by the use of immersive virtual therapy. The system allows patients with upper limb dysfunction to perform a motor and task-oriented training in virtual reality that is individually tailored to their performance. The complete immersion therapy itself is researched and evaluated by medical teams to determine the suitability for rehabilitation of the upper limb after a stroke. The purpose of this article is to provide an overview of the latest research (2019-2022) on immersive virtual reality with head-mounted displays using in rehabilitation of the upper extremities of stroke patients.

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.

Validation of an immersive virtual reality device accepted by seniors that preserves the adaptive behavior produced in the real world

Falls in the elderly are a major societal issue. Virtual reality appears as a relevant tool to propose gait training programs to prevent the occurrence of falls. The use of a head-mounted display allows overground walking during fully immersive virtual training sessions. Our long-term ambition is to develop gait training programs with a head-mounted display to propose enjoyable and personalized training content for the elderly. Before proposing these programs, several methodological precautions must be taken. The first concerns the supposed similarity of the adaptive behavior produced in the real world and in virtual reality. The second concerns the acceptance of the virtual reality device before and after use. Twenty older adults performed a locomotor pointing task in three conditions including a real-world condition, a virtual-world condition consisting in a replica of the real-world condition, and a virtual condition in which the locomotor pointing task was performed in a different context. From feet positions in relation to the position of a target, gait adaptability behavior was investigated. In line with previous studies, step adjustments (needed and produced) were investigated through a combination of inter-trial and trial-by-trial analyses. The results highlighted that participants adopted the same gait adaptability behavior whatever the type of environment (real vs. virtual). Gait analyses suggested the use of a generic control mechanism based on information-movement coupling. We also demonstrated that older adults accepted the virtual reality device before and after use. With these methodological locks removed, it is now possible to design training programs in virtual reality to prevent falls in the elderly.

Effectiveness of Early Rehabilitation with Exergaming in Virtual Reality on Gait in Patients after Total Knee Replacement

Total knee replacement (TKR) is the treatment of choice for advanced stages of osteoarthritis but it requires good postoperative rehabilitation. This study aimed to assess the effectiveness of exercises using virtual reality to improve gait parameters in patients after TKR. Fifty-nine patients 7−14 days after TKR surgery were divided into a study group (VRG, n = 38) and a control group (CG, n = 21). Both groups underwent the same 4-week rehabilitation protocol. The VRG group had 12 additional nonimmersive virtual reality game sessions on the Virtual Balance Clinic prototype system at 30 min each, focusing on gait and balance improvement. Spatiotemporal, force and foot plantar pressure parameters were collected on an instrumented treadmill during a 30 s walk. The most significant improvement was in the symmetry indices of forefoot force, maximum forefoot force, loading response time, and preswing time (p < 0.05) in both groups. Gait speed increased by 31.25% and 44% in the VRG and CG groups, respectively (p < 0.005). However, the extra exergaming sessions did not significantly improve rehabilitation outcomes. Therefore, additional VR training does not improve gait better than standard rehabilitation alone, but the improvement of gait, especially its symmetry, is significant within the first six weeks after surgery.

Effectiveness and Acceptability of e- and m-Health Interventions to Promote Physical Activity and Prevent Falls in Nursing Homes—A Systematic Review

Age-related decreases in physical activity (PA) and a decline in physical functioning lead to increased fall risk. As falls are a major cause of accidental deaths and hospitalization in older adults, PA promotion and fall prevention are important measures, especially in nursing homes (NH). With advances in information and communication technology, e- and m-health solutions have been developed to positively influence various health-related factors. To date, only little research exists on the implementation of these technologies to promote health in NH. Therefore, the objective of this systematic review was to provide an overview of the effectiveness, acceptability, and feasibility of e- and m-health interventions aimed at promoting PA and preventing falls in NH. Additionally, the effectiveness of such interventions regarding the secondary outcomes physical function, cognitive function, neuropsychiatric symptoms, and psychosocial status was examined. A systematic literature search was performed in five databases and studies published until 15 November 2021, were considered for inclusion. All studies that examined the effectiveness and/or the acceptability and feasibility of e- or m-health interventions in promoting PA and preventing falls in NH, without restriction on language or date of publication, were included in the final synthesis. Of the 1,358 records retrieved, 28 studies were included in this systematic review. Twenty-four studies contained digital exergaming as an intervention or as a part of the intervention, the four additional studies on e-health interventions only examined a small number of outcomes. No m-health intervention study was identified. Data synthesis indicates that exergaming may be effective in reducing the number of falls and fall risk in NH residents. Several significant improvements were also reported regarding secondary outcomes albeit not consistent across studies. No conclusion can be drawn about the effects of exergaming and other e-health interventions on PA, as data is scarce. E-health interventions were mostly reported as feasible and well accepted by NH residents. However, these findings may not be applicable to NH residents with advanced physical and/or cognitive impairments, since they were excluded in many studies. Therefore, more research examining other digital solutions besides exergaming to promote PA in this specific population is critical.

Physiotherapy Programmes Aided by VR Solutions Applied to the Seniors Affected by Functional Capacity Impairment: Randomised Controlled Trial

Modern technologies are presently harnessed in response to a complex challenge of providing physiotherapeutic management in older adults. Fully immersive virtual reality (VR) solutions are acknowledged to viably enhance the overall effectiveness of traditional physiotherapeutic methods. A total of 60 community-dwelling older adults (over 75 years of age) were recruited for the study protocol. They were subsequently randomly split into four equally sized study groups (VR, CVR, OCULUS, and the classic programme group (OTAGO), and the physiotherapy sessions were pursued in the subjects’ homes for 3 weeks, 3 times a week, for 30 min in each group. At the first measurement point, respective study groups differed significantly in functional performance, as expressed in gait (POMA G) and individual static balance. The post hoc analysis indicated significantly higher scores in POMA G for the classic programme group vs. the results of the VR and CVR groups. On the other hand, the OCULUS group held significantly higher scores in individual balance and TUG, as compared to the other groups (p < 0.001). Making use of a virtual reality (VR) environment in the physiotherapeutic management of community-dwelling older adults appreciably enhanced individual functional performance, especially in terms of static balance. Physiotherapy management aided by VR technology solutions offers a viable alternative to traditional physiotherapeutic regimens (e.g., OTAGO programme) in enhancing individual functional performance. The innovatively self-designed VIRTUAL REALITY COMPREHENSIVE REHABILITATION ROOMS (VRCRR) solution may help out in pursuing a complex physiotherapy programme on an individual basis within one’s own home environment.

Effects of an 8-Week Virtual Reality Training Program on Pain, Fall Risk, and Quality of Life in Elderly Women with Chronic Low Back Pain: Double-Blind Randomized Clinical Trial

Objective: Low back pain (LBP) and falls are among the major problems experienced by the elderly population. The present study investigated the effectiveness of an 8-week virtual reality training (VRT) program in helping relieve pain, minimize fall risk, and improve quality of life (QoL) in elderly women suffering from chronic LBP (CLBP). Materials and Methods: Twenty-five elderly women (VRT/intervention group = 13, control group = 12) with CLBP and aged 65 to 75 years were recruited. The VRT involved three 30-minute weekly sessions of exercises that were carried out using the Xbox Kinect headset. Pain intensity, fall risk, and QoL were assessed via the Visual Analog Scale, the Biodex Balance System, and the 36-Item Short Form Health Survey, respectively. Results: The outcomes of a one-way analysis of covariance indicated that the pain intensity score of the intervention group significantly decreased after participation in the VRT program (P = 0.001). The intervention group also showed reduced fall risk (P = 0.001) and elevated QoL (P = 0.001). Conclusion: The results confirmed that the VRT program can be regarded as a valid therapeutic intervention that helps reduce patients' symptoms and increase the effectiveness of exercises in the elderly by teaching pain-related insight as well as enhancing QoL and reduce fall risk through various movements.

The effects of virtual reality training on clinical indices and brain mapping of women with patellofemoral pain: a randomized clinical trial

Background

Virtual reality training (VRT) is a new method for the rehabilitation of musculoskeletal impairments. However, the clinical and central effects of VRT have not been investigated in patients with patellofemoral pain (PFP). To comprehensively assess the effects of VRT on clinical indices and brain function, we used a randomized clinical trial based on clinical and brain mapping assessment.

Methods

Twenty-six women with PFP for more than 6 months were randomly allocated to 2 groups: intervention and control. The intervention consisted of lifestyle education + 8 weeks VRT, in 24 sessions each lasting 40 min of training, whereas the control group just received lifestyle education. The balance was the primary outcome and was measured by the modified star excursion balance test. Secondary outcomes included pain, function, quality of life, and brain function which were assessed by visual analogue scale, step down test and Kujala questionnaire, SF-36, and EEG, respectively. Pre-intervention, post-intervention and follow-up (1 month after the end of the intervention) measurements were taken for all outcome measures except EEG, which was evaluated only at pre-intervention and post-intervention). Analyses of variance was used to compare the clinical outcomes between the two groups. The independent t-test also was used for between group EEG analyses.

Results

Balance score (P < 0.001), function (P < 0.001), and quality of life (P = 0.001) improved significantly at post-intervention and 1 month follow-up in the VRT group compared with the control group. VRT group showed a significantly decreased pain score (P = 0.004). Alpha (P < 0.05) and theta (P = 0.01) power activity also increased in the brain of the VRT group.

Conclusion

This study demonstrated that long term VRT was capable of improving both clinical impairments and brain function in patients with PFP. Therefore, therapists and clinicians can use this method as a more holistic approach in the rehabilitation of PFP.

What we need as we get older: needs assessment for the development of a community geriatrics service in an Australian context

Background

The aim of this study was to inform the development of a Community Geriatrics Service (CGS) that addressed the healthcare and social needs of community dwelling older people in an Australian context.

Methods

Stakeholders (N = 108) took part in a ‘needs assessment’ involving 30-min semi-structured interviews with general practitioners (GPs; N = 49), and three 2-h focus groups (community engagement meetings; N = 59) with older people, informal caregivers, allied healthcare workers, and nursing home directors. Data were transcribed and thematically coded, mapped to source and weighted to the frequency that the theme was raised across sources.

Results

Five themes informing CGS development and delivery emerged: active health conditions (management of behavioural and psychological symptoms of dementia, falls, multimorbidity, and other relevant conditions), active social challenges (patient non-compliance, need for aged care social workers, caregiver stress, elder abuse, social isolation, and stigma), referrals (availability of specialists, communication, specialist input, and advance care directives), access (lack of transport options, and inaccessibility of local geriatrics clinics and specialists), and awareness (lack of awareness, knowledge, and resources).

Conclusions

The CGS will need to address access, referral processes and health system navigation, which were perceived by stakeholders as significant challenges. These findings warrant the development of a CGS with an integrated approach to aged care, pertinent for the health and social needs of the elderly.

Acceptability Evaluation of the Use of Virtual Reality Games in Smoking-Prevention Education for High School Students: Prospective Observational Study

BACKGROUND

Alternative forms of cigarettes, such as electronic cigarettes (e-cigarettes), are becoming increasingly common among adolescents. Many high schools now provide smoking-prevention education in an attempt to minimize the potential negative health effects and illness burdens e-cigarettes may induce in adolescents. However, it is often difficult to motivate young students to engage with traditional education regarding the harmful effects of tobacco; thus, the development of alternative approaches may be required.

OBJECTIVE

In this study, we aimed to conduct an acceptability evaluation of educational virtual reality games designed to support smoking-prevention measures. We based the acceptability evaluation on the following two experience types: game-playing and content-learning experiences. The paths by which these experience types affect the intention to abstain from smoking were also examined.

METHODS

We applied a prospective observational study design. We developed educational games based on three-dimensional virtual reality technology, in which participants operated joysticks to complete challenge tasks. To increase the possibility of the games fostering motivation to abstain from smoking, the ARCS motivational model (comprising attention, relevance, confidence, and satisfaction) was used as a framework during the games' design. We measured the participants' game-playing experiences by inquiring about the strength of the ARCS elements; content-learning experiences were measured using overall knowledge improvement and the perceived persuasiveness of the content. A total of 130 students participated in the program. Study hypotheses for this evaluation were derived from a literature review. We used partial least squares structural equation modeling to examine the proposed hypotheses.

RESULTS

Based on the responses of the students to questionnaire items concerning attention, relevance, confidence, and satisfaction in the context of the games, most students agreed or strongly agreed that the educational games were motivational, and that their game-playing experiences were positive. Regarding content-learning experiences, there was a significant improvement in knowledge (t129=25.67, P<.001), and most students perceived themselves as being persuaded to abstain from smoking. Attention, relevance, and satisfaction significantly influenced perceived persuasiveness (t=3.19, P<.001; t=4.28, P<.001; and t=3.49, P<.001, respectively); however, confidence did not (t=0.42, P=.67). Perceived persuasiveness, relevance, and satisfaction significantly influenced the intention to abstain from smoking (t=3.57, P<.001). In addition to directly affecting the intention to abstain from smoking, indirect effects were observed from both relevance and satisfaction to intention via perceived persuasiveness (t=2.87, P=.004 and t=2.11, P=.04, respectively). However, intention was not significantly influenced by knowledge improvement.

CONCLUSIONS

Our findings revealed that the educational games were positively accepted by the participating students. This indicates that the integration of the ARCS framework and persuasive strategies is applicable for smoking-prevention education. We recommend that the games be included as teaching materials for smoking-prevention education.

Effects of virtual reality exergame on psychophysiological and postural disorders in elderly patients

Balance impairment at advanced age is a serious medical problem that often has significant implications and affects the quality of the patient’s life. Among the underlying causes are overall slowness of motor response and vestibular syndrome. Virtual reality exergames, including reaction and balance training, hold promise for managing balance dysfunction. The aim of this study was to investigate the effects of a combination rehabilitation program containing elements of virtual reality exergame on the postural and psychophysiological parameters of elderly patients with small vascular disease The study was conducted in 24 patients with small vascular disease (median age: 66 years). All patients underwent a virtual reality rehabilitation program. Psychophysiological, postural and clinical evaluations were performed at baseline and after the program was completed. Balance function measured on the Berg scale improved significantly and was 53 [52; 55] after the training program vs 50 [45; 54] at baseline (p < 0.05). The strategy of balance control also changed: the Romberg ratio was 266 [199.5; 478.5] before rehabilitation and 221 [149.25; 404] after the program was completed (p < 0.05). The most pronounced changes in the measured psychophysiological parameters occurred in the simple audiomotor reaction, which improved from 210 [174.25; 245.5] at baseline to 180.5 [170.5; 208] after rehabilitation (p < 0.05). Thus, the combination balance and reaction virtual reality training is an effective rehabilitation method for advanced-age patients with balance impairment.

The Effect of Virtual Reality Training on Anticipatory Postural Adjustments in Patients with Chronic Nonspecific Low Back Pain: A Preliminary Study

Objectives

This study is aimed at exploring the effects of virtual reality (VR) training on postural control, measured by anticipatory and compensatory postural adjustments (APAs and CPAs, respectively), in patients with chronic nonspecific low back pain (CNLBP) and the potential neuromuscular mechanism of VR training.

Methods

Thirty-four patients were recruited and randomly assigned to the VR group (n = 11), the motor control exercise group (MCE, n = 12) and the control group (CG, n = 11). The VR group received VR training using Kinect Xbox 360 systems and magnetic therapy. Besides magnetic therapy, the participants in the MCE group performed real-time ultrasound-guided abdominal drawing-in maneuver (ADIM) and four-point kneeling exercise. The CG only received magnetic therapy. Surface muscle electromyography (sEMG) was used to record the muscle activities of transverse abdominis (TrA), multifidus (MF), lateral gastrocnemius (LG), and tibialis anterior (TA) during ball-hitting tasks. The muscle activation time and integrals of the electromyography activities (IEMGs) during the APA and CPA stages were calculated and used in the data analysis. The visual analogue scale (VAS) and Oswestry dysfunction index (ODI) scores were also recorded.

Results

A significant interaction effect of time × group was observed on the activation time of TrA (p = 0.018) and MF (p = 0.037). The post-intervention activation time of the TrA was earlier in the VR group (p = 0.029). In contrast, the post-intervention activation time of the MF was significantly delayed in the VR group (p = 0.001). The IEMGs of TrA (p = 0.002) and TA (p = 0.007) during CPA1 significantly decreased only in the VR group after the intervention. The VAS scores of three group participants showed significant decreases after intervention (p < 0.001).

Conclusions

Patients with CNLBP showed reciprocal muscle activation patterns of the TrA and MF muscles after VR training. VR training may be a potential intervention for enhancing the APAs of the patients with CNLBP.

The Effects of Exergaming on Sensory Reweighting and Mediolateral Stability of Women Aged Over 60: Usability Study

Background

Older adults tend to experience difficulties in switching quickly between various reliable sensory inputs, which ultimately may contribute to an increased risk of falls and injuries. Sideward falls are the most frequent cause of hip fractures among older adults. Recently, exergame programs have been confirmed as beneficial tools for enhancing postural control, which can reduce the risk of falls. However, studies to explore more precisely which mechanism of exergaming directly influences older women’s ability to balance are still needed.

Objective

Our aim was to evaluate, in a single-group pretest/posttest/follow-up usability study, whether Kinect exergame balance training might have a beneficial impact on the sensory reweighting in women aged over 60.

Methods

A total of 14 healthy women (mean age 69.57 [SD 4.66] years, mean body mass index 26.21 [SD 2.6] kg/m²) participated in the study. The volunteers trained with the commercially available games of Kinect for Xbox 360 console 3 times (30 minutes/session) a week over a 6-week period (total of 18 visits). Participants’ postural sway in both the anteroposterior (AP) and mediolateral (ML) directions was recorded with NeuroCom Balance Master 6.0. To assess and measure postural sensory reweighting, the Modified Clinical Test of Sensory Interaction in Balance was used, where volunteers were exposed to various changes in visual (eyes open or eyes closed) and surface conditions (firm or foam surface).

Results

In the ML direction, the Kinect exergame training caused a significant decrease in the sway path on the firm surface with the eyes open (P<.001) and eyes closed (P=.001), and on the foam surface with the eyes open (P=.001) and eyes closed (P<.001) conditions compared with baseline data. The follow-up measurements when compared with the baseline data showed a significant change in the sway path on the firm surface with the eyes open (P<.001) and eyes closed (P<.001) conditions, as well as on the foam surface with the eyes open (P=.003) and eyes closed (P<.001) conditions. Besides, on the firm surface, there were no significant differences in sway path values in the AP direction between the baseline and the posttraining measurements (eyes open: P=.49; eyes closed: P=.18). Likewise, on the foam surface, there were no significant differences in sway path values in the AP direction under both eyes open (P=.24) and eyes closed (P=.84) conditions.

Conclusions

The improved posturography measurements of the sway path in the ML direction might suggest that the Kinect exergame balance training may have effects on sensory reweighting, and thus on the balance of women aged over 60. Based on these results, Kinect exergaming may provide a safe and potentially useful tool for improving postural stability in the crucial ML direction, and thus it may help reduce the risk of falling.

Effects of user experiences on continuance intention of using immersive three-dimensional virtual reality among institutionalized older adults

AIM

To evaluate the acceptance of three-dimensional virtual reality programs and to explore the factors influencing the acceptance of the programs among the institutionalized older adults.

DESIGN

A cross-sectional explanatory study.

METHODS

A total of 71 residents completed the program successfully. They were invited to join a 9-week program included eight activities related to horticultural therapy in a virtual environment. Data were collected by structured questionnaires from August 2018 to February 2019. Ten association hypotheses were derived from the literature review. Partial least squares structural equation modelling was used to examine the proposed hypotheses.

RESULTS

Program acceptance was defined as virtual reality practices and continuous usage intention. Frequency of practice was about 12 times during 9-week free-trial period, and the score of continuance usage intention was 13.06 (maximum value of 15). The findings indicated that virtual reality practices were significantly affected by presence and the presence was significantly affected by involvement and interactivity. Continuance usage intention was significantly affected by involvement; and involvement was significantly affected by interactivity. However, continuance usage intention was not significantly influenced by virtual reality practices.

CONCLUSIONS

The findings supported that immersive three-dimensional virtual reality program was accepted by the institutionalized older adults. The acceptance, in terms of virtual reality practices and continuous usage intention, was influenced by different paths. The findings have a potential impact on the design of virtual reality technology for the care of institutionalized older adults.

IMPACT

What problem did the study address? There were controversial findings about the acceptance of immersive 3D virtual reality program among older adults. What were the main findings? Interactivity advanced the sense of presence and, thus, resulted in a higher frequency of virtual reality practices. Interactivity enhanced perception of involvement, thus, contributing to an increased intention of continuous usage Where and on whom will the research have an impact? The immersive 3D virtual reality program was appropriate for older adults, even for first time users or individuals aged over 80 years. The findings revealed new insights for developing immersive 3D virtual reality programs for the older adults.

Feasibility, Acceptability, and Efficacy of Virtual Reality Training for Older Adults and People With Disabilities: Single-Arm Pre-Post Study

BACKGROUND

Unlike most virtual reality (VR) training programs that are targeted at homogenous populations, a set of VR games for rehabilitation purposes targeted at a heterogeneous group of users was developed. The VR games covered physical training, cognitive training (classification and reality orientation), community-living skills training, and relaxing scenery experiences. Special considerations for local older adults and people with disabilities were made in terms of hardware choice and software design.

OBJECTIVE

This study aimed to evaluate the feasibility, acceptance, and efficacy of VR training among users with varying abilities.

METHODS

A single-arm pretest-posttest evaluation study was conducted. The participants of the evaluation study were encouraged to undergo 30-minute VR training three times a week for 6 weeks. The 30-minute session consisted of 10 minutes of upper-limb motion games, 10 minutes of lower-limb motion games, and 10 minutes of cognitive games/community-living skills training/relaxing scenery experiences, as appropriate. On completion of each session, usage statistics were documented via the built-in VR software, whereas feedback on the experience of the VR games and adverse events was collected via self-reports and staff observations. Feasibility was reflected by usage statistics, and acceptance was reflected by positive feedback. In addition, health outcomes, including upper-limb dexterity, functional mobility, cognitive function, and happiness, were assessed at baseline, as well as 6 weeks and 3 months after baseline. The primary outcomes were upper-limb dexterity and acceptance of playing VR games.

RESULTS

A total of 135 participants with a mean age of 62.7 years (SD 21.5) were recruited from May 2019 to January 2020, and 124 (91.9%) completed at least one follow-up. Additionally, 76.3% (103/135) of the participants could attend at least 70% of the proposed 18 sessions, and 72.5% (1382/1906) of the sessions had a training time of at least 20 minutes. Linear mixed effect models showed statistically significant effects in terms of upper-limb dexterity (small effect) and cognitive function (moderate effect). Among the 135 participants, 88 provided positive comments. Additionally, 10.4% (14/135) reported mild discomfort, such as dizziness, and none reported severe discomfort.

CONCLUSIONS

A set of VR training games for rehabilitation could be applied to users with heterogeneous abilities. Our VR games were acceptable to local older adults and those with different disabilities. Benefits in upper-limb dexterity and cognitive function were observed despite partial compliance to the training protocol. Service providers could refer to our experiences when developing VR training systems for their clients.

The effects of exergames on muscle strength: A systematic review and meta-analysis

This systematic review and meta-analysis examined studies on the chronic effects of exergames on muscle strength in humans. PubMed, Scopus, CENTRAL, Web of Science, SciELO, Biblioteca Virtual em Saúde, and Google Scholar were searched, and manual searches of the reference lists of included studies and hand-searches on Physiotherapy Evidence Database and ResearchGate were conducted from inception to August 10, 2020. Randomized and non-randomized exergame intervention studies with or without a non-exercise group and/or a "usual care intervention group" (any other intervention that did not incorporate exergames), which evaluated muscle strength through direct measurements, were included. Forty-seven and 25 studies were included in the qualitative review and meta-analysis, respectively. The between-groups meta-analyses showed no significant differences between exergames and non-exercise control groups for handgrip strength in heathy/unhealthy middle-aged/older adults or knee extension maximum voluntary isometric contraction (MVIC) in healthy older adults. However, exergames provided a greater increase in handgrip strength, knee flexion MVIC, and elbow extension MVIC, but not knee extension MVIC or elbow flexion MVIC, in individuals with different health statuses when compared to usual care interventions. Also, there was a greater increase in handgrip strength in children with hemiplegic cerebral palsy favouring usual care plus exergames compared to usual care interventions. These results suggest that exergames may improve upper and lower limb muscle strength in individuals with different heath statuses compared to usual care interventions, but not muscle strength in middle age/older adults after accounting for random error. Also, exergames appear to be a useful tool for improving handgrip strength in children with hemiplegic cerebral palsy when added to usual care. However, as the exergame interventions were applied in different populations and there currently are many different approaches to perform exergames, future randomized controlled trials with high methodological quality and large sample sizes are needed to provide more compelling evidence in favour of a specific exergame protocol, or to elucidate exergame protocol design principles that appear to strongly influence outcomes.

Immersive virtual reality is effective in the rehabilitation of older adults with balance disorders: A randomized clinical trial

QUESTION

What are the effects of immersive virtual reality (IVR) training compared to conventional physiotherapy on body balance and risk of falls in older adults with balance disorders?

DESIGN

A randomized controlled trial with two intervention arms, concealed allocation, per-protocol analysis, and blinded assessment.

PARTICIPANTS

Thirty-seven older adults with balance disorders and risk of falling.

INTERVENTION

Participants were randomized into two groups: a control group, which received balance training with conventional physiotherapy using multimodal circuit exercises, and an experimental group, which received balance training using immersive virtual reality. Both groups received 16 individual sessions, twice a week.

OUTCOME MEASURES

The primary outcome was functional balance. Secondary outcomes were static balance, gait speed, functional range, dizziness symptoms, and fear of falling. Safety was ensured by assessing any adverse events during the intervention.

RESULTS

After 16 sessions, in the intragroup analysis, the functional balance score in the experimental group increased by 3.00 (95% CI 1.42 to 4.57) and in the control group by 3.88 (95% CI 2.16 to 5.59). Both groups improved in assessments of sensory interaction and anterior reach. Only the experimental group presented increased mobility and reduced dizziness. After two months, there was a maintenance of gains in functional balance and a reduction of the gains in functional reach for both groups. In the intergroup comparison, there was no significant difference.

CONCLUSION

Immersive Virtual Reality training proved to be effective for balance-related outcomes, although it was not superior to conventional therapy.

Ambient assisted living technology-mediated interventions for older people and their informal carers in the context of healthy ageing: A scoping review

BACKGROUND AND AIMS

There is a growing demand for health and social care services to provide technology-mediated interventions that promote the health and well-being of older people with health or care needs and of their informal carers. The objectives of this study were to scope and review the nature and extent of prior intervention studies involving ambient assisted living technology-mediated interventions for older people and their informal carers, and how and in what ways (if any) the goals and aims of these interventions reflected the domains of the World Health Organization framework for healthy ageing.

METHODS

We conducted a scoping review. Data were collected between June and October 2018 with an updated search in October 2020. A total of 85 articles were eligible for inclusion.

RESULTS

Nine categories described the aims and content of the included studies. The healthy ageing domain "Ability to meet basic needs" was mirrored in four categories, whereas "Ability to contribute to society" was not addressed at all.

CONCLUSION

The ways in which domains of healthy ageing are mirrored suggest that there is an emphasis on individual factors and individual responsibility, and a lack of attention given to broader, environmental factors affecting healthy ageing. Only a few of the studies used a dyadic approach when assessing health outcomes concerning older people and their informal carers.

Technology Utilization in Fall Prevention

ABSTRACT

Falls, defined as unplanned descents to the floor with or without injury to an individual, remain to be one of the most challenging health conditions. Fall rate is a key quality metric of acute care hospitals, rehabilitation settings, and long-term care facilities. Fall prevention policies with proper implementation have been the focus of surveys by regulatory bodies, including The Joint Commission and the Centers for Medicare and Medicaid Services, for all healthcare settings. Since October 2008, the Centers for Medicare and Medicaid Services has stopped reimbursing hospitals for the costs related to patient falls, shifting the accountability for fall prevention to the healthcare providers. Research shows that almost one-third of falls can be prevented and extensive fall prevention interventions exist. Recently, technology-based applications have been introduced in healthcare to obtain superior patient care outcomes and experience via efficiency, access, and reliability. Several areas in fall prevention deploy technology, including predictive and prescriptive analytics using big data, video monitoring and alarm technology, wearable sensors, exergame and virtual reality, robotics in home environment assessment, and personal coaching. This review discusses an overview of these technology-based applications in various settings, focusing on the outcomes of fall reductions, cost, and other benefits.

The Potential of Immersive Virtual Reality for Cognitive Training in Elderly

The number of elderly is growing rapidly, including those that struggle with cognitive decline and, consequently, activities of daily living. Developing interventions that slow down cognitive decline would greatly benefit the autonomy of these elderly, as well as their caretakers. Virtual reality (VR) is an immersive and interactive human-computer interface with real-time simulation that is suggested to be a promising tool to improve cognitive functioning. This literature review discusses the features of immersive VR, including its opportunities and limitations, that are of special relevance for improving cognition in elderly. First, the high flexibility of VR allows for personalized and safe training of potentially harmful situations and isolated aspects of tasks. Second, VR's dynamic and real-time feedback on performance provides a labor-extensive tool for caretakers in elderly care. Third, the acquisition of high resolution data enables the exposure of subtle changes over time, relevant for detecting the nature and extent of cognitive changes in elderly, including those with dementia. Fourth, immersive VR has been related to cybersickness. Finally, VR is immersive and enables the perception and expression of emotions, motor behaviors, and multiple senses. Aged subjects are found to have sparing of emotional learning and show increased reliance on multisensory integration for learning. Moreover, they experience high levels of flow, motivation, and presence in VR setups. Despite the clear potential of immersive VR, the studies available are small scale and have not been replicated. The digital illiteracy of elderly and healthcare personnel form an additional barrier for implementation. Hence, while replication of outcomes and standardization of VR interventions is required before it can be used in standard care, VR may provide a particularly effective tool for training cognition in elderly.

Finding NEEMO: towards organizing smart digital solutions in orthopaedic trauma surgery

There are many digital solutions which assist the orthopaedic trauma surgeon. This already broad field is rapidly expanding, making a complete overview of the existing solutions difficult.The AO Foundation has established a task force to address the need for an overview of digital solutions in the field of orthopaedic trauma surgery.Areas of new technology which will help the surgeon gain a greater understanding of these possible solutions are reviewed.We propose a categorization of the current needs in orthopaedic trauma surgery matched with available or potential digital solutions, and provide a narrative overview of this broad topic, including the needs, solutions and basic rules to ensure adequate use in orthopaedic trauma surgery. We seek to make this field more accessible, allowing for technological solutions to be clearly matched to trauma surgeons' needs. Cite this article: EFORT Open Rev 2020;5:408-420.

Emerging Smart Home Technologies to Facilitate Engaging With Aging

Engaging with aging (EWA), the ongoing process of an individual to identify resources and implement adaptive strategies to maximize quality of life, may be enhanced by advances in information technology and adaptive upgrades to the built environment. Smart home technologies (SmHT) introduce passive monitoring features into the residential infrastructure to promote older adults' ability to manage day-to-day living and age in place. This article provides an overview of current and emerging SmHT and discusses opportunities to leverage this technology for enhancing the capacity of older adults to engage with their own aging. There are opportunities to create smart homes that enhance physical and cognitive capacity for older adults, but there are also ethical and practical challenges that will inform the design of future smart home systems.

Exergames and Depressive Symptoms in Older Adults: A Systematic Review

To synthesize and critique studies that examined the impact of exergames on depressive symptoms in older adults. Articles were retrieved from the databases CINAHL, Embase, PsychINFO, and Medline. Studies were included in the review if they involved a physical activity/videogame intervention and measured outcomes of depressive symptoms in older adults. The search generated 957 articles for consideration, which were narrowed to 17 articles after applying exclusion criteria. In studies that required depressive symptoms as an inclusion criterion, there was an improvement in depressive symptoms in older adults following the exergame intervention. In studies that did not require depressive symptoms as an inclusion criterion, researchers found mixed results. Future older adult exergame research should measure depression as a primary outcome, utilize control groups with random sampling, consist of larger sample sizes, and include people with disabilities.

Can exergames contribute to improving walking capacity in older adults? A systematic review and meta-analysis

BACKGROUND

The accessibility, low cost and motivation generated by exergames has fostered its rapid expansion as a rehabilitation technique.

OBJECTIVE

To estimate the effectiveness of rehabilitation programs using IVGT in improving walking capacity of people aged 60 years and over.

MATERIALS AND METHODS

The electronic data research following the PRISMA Statement (Scopus, Cochrane, Web of Science, OT Seeker, National Guideline Clearinghouse, Trip Database, CSIC Spanish National Research Council) was completed in September 2018. The results of randomized clinical trials using exergames for rehabilitation of walking capacity were combined. The calculations have followed the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. The Grading of Recommendations Assessment, Development and Evaluation system was used to evaluate the quality of the evidence.

RESULTS

We obtained data from 14 trials, including 11 meta-analysis studies. The size of exergames effects on walking capacity is moderate, but significant (SMD -0.56; 95 % CI: -0.90, -0.21; p = 0.002). Effectiveness was greater to recover the ability to transfer from one position or place to another (SMD -1.02; CI 95 %: -1.70, -0.35; P = 0.003). The intervention protocols, their duration and intensity varied considerably. The lack of masking, the allocation concealment, the absence of assessor blinding were the main causes of bias so the final grade of evidence has been low for walking and very low for transfers.

CONCLUSIONS

Positive clinical effects of exergames have been found to improve walking capacity, but the quality of evidence to refute its effectiveness is weak with risk of bias. Further research is needed in order to know the actual magnitude of its effect.

An Immersive Motor Protocol for Frailty Rehabilitation

Frailty is a pre-clinical condition that worsens physical health and quality of life. One of the most frequent symptoms of frailty is an increased risk of falling. In order to reduce this risk, we propose an innovative virtual reality motor rehabilitation program based on an immersive tool. All exercises will take place in the CAVE, a four-screen room with a stationary bike. The protocol will include two types of exercises for the improvement of balance: "Positive Bike" and "Avoid the Rocks." We will choose evaluation scales related to the functional aspects and subjective perception of balance. Our aim is to prove that our innovative motor rehabilitation protocol is as effective as or more effective than classical rehabilitation.
