“…Recently VR exergames for adults that monitor and train physical activity have been developed for: posture ( Solis-Escalante et al, 2019 ; Carr et al, 2020 ; Imaoka et al, 2020 ), falls ( Chen et al, 2020 ; Liston et al, 2021 ), dual-task walking ( Kizony et al, 2017 ; Janouch et al, 2018 ; Kafri et al, 2021 ). As well as assessing cognitive health and providing comfort in patients with neurological diseases and communication difficulties (e.g., Stasolla et al, 2021 ).…”

“…As well as assessing cognitive health and providing comfort in patients with neurological diseases and communication difficulties (e.g., Stasolla et al, 2021 ). In addition, various exergames investigate the correlation of multisensory stimulation and age on realistic daily-life activities ( Wechsler et al, 2018 ; Souza-Silva et al, 2019 ; Carr et al, 2020 ; Imaoka et al, 2020 ). Some also investigate the maintenance of posture and the response to fall and how they are age-dependently influenced by sound and vision (e.g., Stapleton et al, 2014 ; Lupo and Barnett-Cowan, 2018 ).…”

“…The index correlates strongly with standard cognitive and physical activity measurements. Changes in postural sway by older adults are also indicative of cognitive impairment, and several VR exergames have been addressing this issue ( Carr et al, 2019 ; Liao et al, 2019 ; Imaoka et al, 2020 ). Interestingly, 12 weeks training significantly improved dual-task gait performance in older mildly cognitively impaired adults ( Liao et al, 2019 ).…”

“…It also should be noted that recent research indicates that particular implemented VR exergames can yield biomarkers for early detection of various CNDs (e.g., Imaoka et al, 2020 ; Jiang et al, 2021 ; Pieruccini-Faria et al, 2021 ). These have the potential to be developed and integrated into rehabilitation programs.…”

A major concern of public health authorities is to also encourage adults to be exposed to enriched environments (sensory and cognitive-motor activity) during the pandemic lockdown, as was recently the case worldwide during the COVID-19 outbreak. Games for adults that require physical activity, known as exergames, offer opportunities here. In particular, the output of the gaming industry nowadays offers computer games with extended reality (XR) which combines real and virtual environments and refers to human-machine interactions generated by computers and wearable technologies. For example, playing the game in front of a computer screen while standing or walking on a force plate or treadmill allows the user to react to certain infrastructural changes and obstacles within the virtual environment. Recent developments, optimization, and minimizations in wearable technology have produced wireless headsets and sensors that allow for unrestricted whole-body movement. This makes the virtual experience more immersive and provides the opportunity for greater engagement than traditional exercise. Currently, XR serves as an umbrella term for current immersive technologies as well as future realities that enhance the experience with features that produce new controllable environments. Overall, these technology-enhanced exergames challenge the adult user and modify the experience by increasing sensory stimulation and creating an environment where virtual and real elements interact. As a therapy, exergames can potentially create new environments and visualizations that may be more ecologically valid and thus simulate real activities of daily living that can be trained. Furthermore, by adding telemedicine features to the exergame, progress over time can be closely monitored and feedback provided, offering future opportunities for cognitive-motor assessment. To more optimally serve and challenge adults both physically and cognitively over time in future lockdowns, there is a need to provide long-term remote training and feedback. Particularly related to activities of daily living that create opportunities for effective and lasting rehabilitation for elderly and sufferers from chronic non-communicable diseases (CNDs). The aim of the current review is to envision the remote training and monitoring of physical and cognitive aspects for adults with limited mobility (due to disability, disease, or age), through the implementation of concurrent telehealth and exergame features using XR and wireless sensor technologies.

“…A study analyzing postural sway behaviors of people with AD also found that attentional demand during dual-task activity and visual challenge contributed to the postural instability of the AD population (Bahureksa et al, 2017 ; Mesbah et al, 2017 ). With the aim of improving body balance assessment for dementia screening using a visual challenge, we have created a new assessment system combining a stabilometer and head-mounted display (HMD)-based virtual reality (VR) technology (Imaoka et al, 2020a ). The new system was developed to trigger postural sway in anterior-posterior direction intentionally by giving a visual flow of moving VR environments forwards and backwards.…”

BackgroundDementia is becoming a relevant problem worldwide. A simple screening at an early stage will be important to detect the risk of developing dementia. Vestibular dysfunction is likely to be associated with cognitive impairment. Since head-mounted display (HMD) virtual reality (VR) technology has the potential to activate the vestibular function, assessing postural sway with visual stimulation using HMD VR technology could be potentially useful for dementia screening.ObjectiveThe purpose of this study is to evaluate the effect of HMD-based VR visual stimuli on posture in older adults and the relationship between the stimulated body sway behaviors and cognitive performance.MethodUsing a cross-sectional study design, we investigated the effect of an optokinetic design-based room with stripes (OKR) VR environment oscillating forwards and backwards at 23/60Hz. Center of pressure (COP) displacement was measured in older adults aged 65 years and over in the OKR VR environment. The frequency response of COP was compared to the cognitive performance of the Montreal Cognitive Assessment (MoCA).Results20 healthy older adults (70.4 ± 4.9 years; 27.2 ± 1.6 MoCA score) and 3 people with mild cognitive impairment (74.7 ± 4.0 years; 20.3 ± 2.1 MoCA score) were assessed. The results reveal that the oscillating OKR VR environment induced different postural sway in the anterior-posterior direction in the real world. Correlation analysis shows that the cognitive test score was associated with the frequency response of stimulated postural sway in the anterior-posterior direction (frequency Band 1 of 0−0.5Hz related to the visual and vestibular systems: rs = 0.45, P = 0.03).ConclusionOutcomes would suggest that a potential link may emerge between cognition and posture when the HMD-based VR visual stimuli are applied. The simple screening of stimulated postural sway could explain cognitive functioning. Further studies are warranted to clarify the vestibular system and spatial cognitive function more specifically in the proposed assessment system.

Postural sway and eye movements are potential biomarkers for dementia screening. Assessing the two movements comprehensively could improve the understanding of complicated syndrome for more accurate screening. The purpose of this research is to evaluate the effects of comprehensive assessment in healthy older adults (OA), using a novel concurrent comprehensive assessment system consisting of stabilometer and virtual reality headset. 20 healthy OA (70.4 ± 4.9 years) were recruited. Using a cross-sectional study design, this study investigated the effects of various dual-tasking paradigms with integrated tasks of visuospatial memory (VM), spatial orientation (SO), and visual challenge on posture and saccades. Dual-task paradigms with VM and SO affected the saccadic eye movements significantly. Two highly intensive tests of anti-saccade with VM task and pro-saccade with SO task also influenced postural sway significantly. Strong associations were seen between postural sway and eye movements for the conditions where the two movements theoretically shared common neural pathways in the brain, and vice versa. This study suggests that assessing posture and saccades with the integrated tasks comprehensively and simultaneously could be useful to explain different functions of the brain. The results warrant a cross-sectional study in OA with and without dementia to explore differences between these groups.
