This prospective, single-arm feasibility study aims to evaluate the feasibility of a 12-week immersive exergame program using an interactive wall in older adults living in nursing homes (EHPAD) or long-term care units (USLD). Exergames are interactive digital games that integrate physical activity into gameplay, requiring users to perform whole-body movements to achieve game objectives while promoting exercise and energy expenditure. Participants will complete two supervised 40-minute sessions per week over 12 weeks. The primary objective is to assess feasibility through acceptability, adherence, and safety. Secondary objectives include evaluating implementation fidelity, preliminary effects on cognition, quality of life and well-being, and characterizing the physical and cognitive demands of the interactive games. Data will include usability and enjoyment questionnaires, attendance, adverse events, heart rate monitoring, cognitive performance (MoCA), quality of life (EQ-5D-5L), psychological well-being (Mini-GDS and QUALIDEM), and game performance. The results will inform the design of a future larger-scale effectiveness trial of immersive exergaming in institutionalized older adults.

Participants will complete a supervised 12-week adapted physical activity program delivered through an immersive interactive wall (NeoXperience). Sessions will be performed twice weekly in groups of four participants and will last approximately 40 minutes, including a warm-up. Games are adapted to participants' physical and cognitive abilities and combine cognitive stimulation with whole-body movements. Heart rate, physical activity intensity, game performance, perceived exertion, fatigue and enjoyment will be monitored throughout the intervention.

Acceptability of the Mur'Aventure program assessed using the French System Usability Scale (F-SUS)
Acceptability will be assessed using the French version of the System Usability Scale (F-SUS), a validated 10-item questionnaire evaluating the perceived usability of a system. Total scores range from 0 to 100, with higher scores indicating greater usability and acceptability. Acceptability will be considered achieved if at least 70% of participants obtain a score \>70. Feasibility will be considered successful if all three predefined feasibility criteria (acceptability, adherence, and safety) are met. If one or more criteria are not met, the feasibility of the intervention will be interpreted in light of the unmet criterion(ia), and potential modifications to the intervention or study procedures will be discussed.
Time frame: During the 12-week intervention and immediately after the intervention.
Program adherence : predefined feasibility criteria
Adherence will be evaluated by the completion rate, defined as the proportion of participants completing the entire 12-week intervention. Adherence will be considered good if the completion rate is ≥70%. Attendance rate and dropout rate will also be reported descriptively.
Time frame: Throughout the 12-week intervention.
Safety of the Mur'Aventure program : predefined feasibility criteria
Safety will be assessed by recording the occurrence of serious adverse events (SAEs) throughout the intervention. Safety will be considered acceptable if no serious adverse events related to the intervention occur. Additional descriptive safety measures include perceived fatigue, perceived exertion, and heart rate responses recorded during each intervention session.
Time frame: Throughout the 12-week intervention
Intervention fidelity
To describe the fidelity of program implementation, assessed by the proportion of intervention sessions delivered according to the planned protocol Intervention fidelity will be assessed as the percentage of planned exercise sessions completed according to the study protocol. Higher percentages indicate greater fidelity to the intervention.
Time frame: Throughout the 12-week intervention
Change in Montreal Cognitive Assessment (MoCA) total score
To explore the preliminary effects of the program on cognitive function, assessed by the change in the Montreal Cognitive Assessment (MoCA) total score Cognitive function will be assessed using the Montreal Cognitive Assessment (MoCA), a validated 30-point cognitive screening instrument evaluating memory, executive function, attention, language, visuospatial abilities, abstraction, and orientation. Scores range from 0 to 30, with higher scores indicating better cognitive function. The outcome is the change in total score between baseline and the end of the intervention.
Time frame: Baseline and immediately after the 12-week intervention
Change in EuroQol 5-Dimension 5-Level (EQ-5D-5L) score
To explore the preliminary effects of the program on health-related quality of life, assessed by the change in the EuroQol 5-Dimension 5-Level (EQ-5D-5L) score from baseline to post-intervention. Health-related quality of life will be assessed using the EQ-5D-5L questionnaire, which evaluates mobility, self-care, usual activities, pain/discomfort, and anxiety/depression across five severity levels. Responses are converted into an EQ-5D index value, with higher index values indicating better health-related quality of life. The change in EQ-5D index score between baseline and the end of the intervention will be analyzed
Time frame: Baseline and immediately after the 12-week intervention
Change in Mini-Geriatric Depression Scale (Mini-GDS) score
To explore the preliminary effects of the program on self-reported psychological well-being, assessed by the change in the 4-item Mini-Geriatric Depression Scale (Mini-GDS) score from baseline to post-intervention. Psychological well-being will be assessed using the 4-item Mini-Geriatric Depression Scale (Mini-GDS). Scores range from 0 to 4, with higher scores indicating more depressive symptoms and poorer psychological well-being. The outcome is the change in total score between baseline and the end of the intervention
Time frame: Baseline and immediately after the 12-week intervention.
Change in QUALIDEM total score
To explore the preliminary effects of the program on caregiver-observed well-being, assessed by the change in the French version of the QUALIDEM total score from baseline to post-intervention. Observed well-being will be assessed using the French version of the QUALIDEM questionnaire, a proxy-rated instrument evaluating quality of life in older adults with cognitive impairment. Higher score indicating better quality of life. The outcome is the change in total score between baseline and the end of the intervention.
Time frame: Baseline and immediately after the 12-week intervention.
Mean heart rate during intervention sessions
To describe the physical stimulation induced by the intervention sessions, assessed using heart rate and measured during each session with the Polar Unite wearable device Heart rate will be continuously recorded during each exercise session using a Polar Unite heart rate monitor. Mean heart rate (beats per minute) as well as maximal heart rate will be calculated for each participant during each session. Higher values indicate greater cardiovascular response to exercise.
Time frame: During each intervention session throughout the 12-week intervention.
Cognitive stimulation during the intervention
To describe cognitive stimulation during the intervention, assessed using the game score, number of errors, and completion time automatically recorded during each session Cognitive stimulation will be assessed using the total score, number of errors and completion time automatically recorded by the Mur'Aventure interactive wall software during each exercise session. Higher scores indicate better cognitive stimulation.
Time frame: During each intervention session throughout the 12-week intervention
Mean physical load during intervention sessions
To describe the physical stimulation induced by the intervention sessions, assessed using heart rate and physical load measured during each session with the Polar Unite wearable device Physical load will be estimated using the Polar Unite wearable device. The device provides a proprietary estimate of exercise load based on heart rate and movement data recorded during each session. Higher values indicate greater physical exercise load.
Time frame: During each intervention session throughout the 12-week intervention.
Game engagement during the intervention
To describe game engagement during the intervention, assessed using the game score, number of errors, and completion time automatically recorded during each session Game engagement will be assessed using the total score, number of errors and completion time automatically recorded by the Mur'Aventure interactive wall software during each exercise session. Higher scores indicate better game performance.
Time frame: During each intervention session throughout the 12-week intervention
