Enrolling by invitation at 1 site in Spain. Open to participants aged 16 Years to 50 Years. Per ClinicalTrials.gov, last updated 2026-06-25.

The presented project aims to bring immersive technology to individuals with Down syndrome (DS) through the development of innovative proposals for acquiring skills and abilities, and enhancing their capabilities by combining the motor and cognitive components so important for this group. Various strategies have been used to improve the functionality (physical and cognitive) and quality of life of people with DS; however, one of the problems observed in practice is the low motivation and commitment to the interventions being implemented. In response to this problem, the use of technology and gamified environments has been proposed in recent years to make therapies more engaging. Therefore, this project arises with the objective of developing and evaluating the effects of an immersive intervention program on the physical and cognitive abilities of individuals with Down syndrome.
Down syndrome is the leading cause of intellectual disability and one of the most common genetic disorders, with an estimated prevalence of approximately 34,000 individuals in Spain and around 3,000 in Galicia. This population presents physical, motor, cognitive, and communication characteristics that affect functional ability and independence throughout life, including muscle hypotonia, difficulties in information processing, memory and attention impairments, and delayed language development.
Although various intervention strategies have been developed to improve functionality and quality of life in individuals with Down syndrome, a key limitation in practice is low motivation and adherence to traditional programs. In this context, technology-based and gamified interventions have shown potential to enhance engagement and improve motor outcomes, particularly balance and physical performance.
However, previous evidence has mainly focused on non-immersive exergaming, with limited research on immersive virtual reality approaches. Therefore, this study aims to develop and evaluate an immersive intervention program designed to improve physical and cognitive capacities in individuals with Down syndrome.

Participants will complete a 12-week immersive virtual reality (VR) intervention based on high-intensity, gamified physical exercise, with two (2) supervised sessions per week. The program will take place in a controlled environment within the participants' center's gym and will be supervised by fitness and health professionals.
Behavioral: RVI_Experimental_Immersive Virtual Reality Exergame
Participants will complete a 12-week immersive virtual reality (VR) intervention based on high-intensity, gamified physical exercise, with one (1) supervised sessions per week. The program will take place in a controlled environment within the participants' center's gym and will be supervised by fitness and health professionals.
Behavioral: RVI_ControGroup_Immersive Virtual Reality Exergame
Participants assigned to the experimental group wil complete a 12-week immersive virtual reality (IVR) intervention based on high-intensity gamified physical exercise, with two (2) supervised sessions per week. The program will be conducted in a controlled environment within the participants' center gym and will be supervised by exercise and health professionals. The exergames used will be: Beat Saber (Beat Games) (6 sessions): Participants perform upper-limb and whole-body movements by hitting virtual targets in time with music, promoting coordination, reaction time, and cardiovascular fitness. FitXR (14 sessions): A virtual reality training program based on high-intensity interval training (HIIT), boxing, and functional movement exercises. It enhances cardiovascular endurance, motor coordinat and cognitive engagement through structured tasks with progressively increasing difficulty levels. Alcove VR (1 session): Used as an initial familiarization and adaptat

1. Assessment body composition
Description: Body composition was assessed using the Tanita MC-780 bioelectrical impedance analyzer. Measured variables included fat mass (FM), fat-free mass (FFM), muscle mass (MM), total body water (TBW), and segmental body composition of the trunk and limbs. Unit of Measurement: Fat Mass (FM): kg Fat-Free Mass (FFM): kg Muscle Mass (MM): kg Total Body Water (TBW): kg Segmental Body Composition: kg Interpretation: Higher FFM, MM, and TBW indicate better physical fitness. Lower FM indicates better body composition.
Time frame: 12 weeks
Assessment usability
1\. System usability will be assessed using the System Usability Scale (SUS), a validated 10-item questionnaire. Scores range from 0 to 100, with higher scores indicating better usability. Unit of Measure: SUS score (0-100) Interpretation: Scores ≥68 indicate acceptable usability; scores \>80 indicate excellent usability.
Time frame: 12 weeks
Cognitive parameters: Executive function
Description: Clock Drawing Test (CDT) Participants are asked to draw an analog clock and set the hands to a specified time. Performance is scored using methods such as TRO and TCR, which evaluate the accuracy and organization of the drawing. Unit of measurement Total CDT score (scoring scale) ( 0-20 points) Interpretation Higher scores: better cognitive performance, particularly in executive and visuospatial functions Lower scores: possible impairment in planning, spatial organization, and other cognitive functions
