Influence of Normal Aging and Multisensory Data Fusion on Cybersickness and Postural Adaptation in Immersive Virtual Reality.

Unlabelled: Immersive Virtual Reality (VR) systems are expanding as sensorimotor readaptation tools for older adults. However, this purpose may be challenged by cybersickness occurrences possibly caused by sensory conflicts. This study aims to analyze the effects of aging and multisensory data fusion processes in the brain on cybersickness and the adaptation of postural responses when exposed to immersive VR.

Wireless Lighting System: A New Tool for Assessing Cognitive Functions in the Elderly.

Studies on the effects of aging on cognition have been using the same cognitive tests for decades. A Wireless Lighting System (WLS) could be used to assess cognitive functions in a physically active situation, making the assessment of cognition less isolated and more ecological. This pilot study aimed to evaluate the potential of a WLS for assessing older adults' cognitive functions.

The effects of a new immersive multidomain training on cognitive, dual-task and physical functions in older adults.

The aim of this study was to assess the potential of multidomain training using Immersive and Interactive Wall Exergames (I2WE) to improve the cognitive and physical functions of older adults. This new generation of exergames offers specific advantageous characteristics (e.g.

Tolerance of immersive head-mounted virtual reality among older nursing home residents.

Introduction: Virtual Reality (VR) is a tool that is increasingly used in the aging population. Head-Mounted Displays (HMDs) are stereoscopic vision devices used for immersive VR. Cybersickness is sometimes reported after head-mounted display (HMD) VR exposure.

Factors for optimizing intervention programs for cognition in older adults: the value of exergames.

This review presents factors that could optimize the effectiveness of an intervention program on cognitive health in older adults. Combined, multi-dimensional and interactive programs appear to be relevant. On one hand, for the characteristics to be implemented in the physical dimension of a program, multimodal interventions stimulating the aerobic pathway and muscle strengthening during the solicitation of gross motor activities, seem to be interesting.

The User Experience of an Immersive and Interactive Wall Exergame in Older Adults.

Exergames are promising options for modulating the effects of aging on physical and cognitive functions. A new-generation immersive and interactive wall exergame (I2WE) has emerged in recent years, offering users freedom of movement as well as greater and varied interactions with other players, the environment, and the system than traditional games (e.g.

Is there a relationship between cardiorespiratory fitness and executive performance as function of mental workload in young adults?

In the current study, we have decided to investigate the relationship between cardiorespiratory fitness and executive functions in young adults as a function of mental workload. To achieve our objectives, we have solicited 29 young adults (18-25 years; 12 women) who have first realized the Random Number Generation (RNG) task with two levels of complexity. After each level of complexity, the participants were asked to report on their perceived difficulty.

Mini-Review of Studies Testing the Cardiorespiratory Hypothesis With Near-Infrared Spectroscopy (NIRS): Overview and Perspectives.

The cardiorespiratory hypothesis (CH) is one of the hypotheses used by researchers to explain the relationship between cardiorespiratory fitness and cognitive performance during executive functions. Despite the indubitable beneficial effect of training on brain blood flow and function that may explain the link between physical fitness and cognition and the recognition of the near-infrared spectroscopy (NIRS) as a reliable tool for measuring brain oxygenation, few studies investigated the CH with NIRS. It is still not well understood whether an increase in brain flow by training is translated into an increase in cerebral oxygenation.

Effect of Exergaming on Physical Fitness, Functional Mobility, and Cognitive Functioning in Adults With Down Syndrome.

This study examined whether exergames could improve physical, functional, and cognitive functions in people with Down syndrome. Twelve adults with DS, aged over 35 (M = 50.35, SD = 7.

Motor-cognitive dual-task performance of older women evaluated using Wii Balance Board.

Background: Single- and dual-tasks are influenced by age-related impaired postural balance. Aim of this study was to analyze the Center of Pressure (CoP) oscillation during static balance in the presence or absence of cognitive task on older women.

Methods: Thirty-one healthy older women were assessed in a stand quiet position with open/closed eyes (single-task, OE and CE) and with cognitive task (dual-task, DT) through Wii Balance Board.

Virtual Reality-Based Exercise with Exergames as Medicine in Different Contexts: A Short Review.

There is enough evidence that, nowadays, the sedentary lifestyle is one of the major health problems worldwide, linked to many chronic diseases, including mental comorbidities, systemic hypertension, metabolic dysregulation, and cancer. Although health societies recommend engagement to physical activities, there is an overwhelming number of people remaining sedentary, even knowing the health benefits of regular exercises. One of the main factors that justifies this scenario is the lack of motivation, which is a barrier to people intended to start new habits for health.

Is the "lactormone" a key-factor for exercise-related neuroplasticity? A hypothesis based on an alternative lactate neurobiological pathway.

For many years lactate was seen as a metabolite from glucose metabolism. However, since the last century researchers have shown that this molecule has an important role on liver, muscle, and brain metabolism. Lactate traffics along whole body mediating many biological processes depending on specific situations.

Cognitive Training Game Versus Action Videogame: Effects on Cognitive Functions in Older Adults.

Objective: The purpose of the study was to compare a cognitive training game, Kawashima Brain Training (KBT), and an action videogame, Super Mario Bros (SMB), in their effects on cognitive function in older adults.

Materials And Methods: Thirty-six older adults were randomly assigned to the KBT group, the SMB group, or the no-training no-contact control group. All participants completed several cognitive tests [matrix reasoning, Stroop, Trail Making Test, digit symbol substitution test (DSST), Corsi clock, spatial relation, and number comparison].

French validation of the modified-falls efficacy scale (M-FES Fr).

Introduction: Among the tools assessing fall related self-efficacy, the Modified-Falls Efficacy Scale (M-FES) seems to be a comprehensive and sensitive scale. However, no validated French version exists to this day.

Objective: This study aims to translate the M-FES and validate this French translation (M-FES Fr).

Training the elderly in pedestrian safety: Transfer effect between two virtual reality simulation devices.

Objectives: A virtual-reality training program has been developed to help older pedestrians make safer street-crossing decisions in two-way traffic situations. The aim was to develop a small-scale affordable and transportable simulation device that allowed transferring effects to a full-scale device involving actual walking.

Methods: 20 younger adults and 40 older participants first participated in a pre-test phase to assess their street crossings using both full-scale and small-scale simulation devices.

The braking force in walking: age-related differences and improvement in older adults with exergame training.

The purposes of this present research were, in the first study, to determine whether age impacts a measure of postural control (the braking force in walking) and, in a second study, to determine whether exergame training in physically-simulated sport activity would show transfer, increasing the braking force in walking and also improving balance assessed by clinical measures, functional fitness, and health-related quality of life in older adults. For the second study, the authors developed an active video game training program (using the Wii system) with a pretest-training-posttest design comparing an experimental group (24 1-hr sessions of training) with a control group. Participants completed a battery comprising balance (braking force in short and normal step conditions), functional fitness (Senior Fitness Test), and health-related quality of life (SF-36).

[The effects of video games on cognitive aging].

Advancing age is associated with cognitive decline, which, however, remains a very heterogeneous phenomenon. Indeed, several extrinsic factors seem to modulate the effect of aging on cognition. Recently, several studies have provided evidence that the practice of video games could engender many benefits by favoring the maintenance of cognitive vitality in the elderly.

Effects of interactive physical-activity video-game training on physical and cognitive function in older adults.

The purpose of the present study was to assess the potential of exergame training based on physically simulated sport play as a mode of physical activity that could have cognitive benefits for older adults. If exergame play has the cognitive benefits of conventional physical activity and also has the intrinsic attractiveness of video games, then it might be a very effective way to induce desirable lifestyle changes in older adults. To examine this issue, the authors developed an active video game training program using a pretest-training-posttest design comparing an experimental group (24 × 1 hr of training) with a control group without treatment.
