Cognitive-Motor Exergame Training in Frail Adults

Официальное название

S.M.A.R.T: A Pragmatic Randomised Controlled Trial of Personalized Cognitive-Motor Exergame Training in Frail Community-Dwelling Adults

Обзор

This international multicentre pragmatic randomized controlled trial (RCT) aims to evaluate the effectiveness of personalized, home-based cognitive-motor training using exergames in improving cognitive and motor functions in frail adults. A total of 344 frail participants from five European countries will be enrolled. Participants in the intervention group will engage in a personalized exergame program, while the control group will follow the Otago Exercise Program. Both groups will undergo 12 weeks of training. The primary outcome is balance, a critical component of functional independence and fall prevention, and a common denominator affected in both physical and cognitive frailty. Secondary outcomes including cognitive and motor fall-risk factors, fall incidence, cost-effectiveness, and psychosocial outcomes.

Подробное описание

The global population is aging rapidly, with those aged 60+ expected to double by 2050. While longevity is increasing due to better healthcare and living conditions, this shift poses major challenges, frailty being a key concern. Affecting 5%-58% of older adults, frailty compromises independence, quality of life, and healthcare systems. It is a dynamic condition marked by vulnerability to stressors and can appear as physical, cognitive, or combined frailty.

Physical frailty is well-studied, often defined by low gait speed, fatigue, weakness, weight loss, and reduced activity, but broader health indicators are also used. Cognitive frailty, recognized more recently, is defined as the co-existence of physical frailty and cognitive impairment without dementia. It may signal early dementia risk and greater susceptibility to adverse outcomes.

A core feature of frailty is balance dysfunction, caused by impairments in sensory, cognitive, and motor systems. This is especially problematic during dual tasks, like walking while talking, where attention is divided. Such deficits increase fall risk and accelerate cognitive and physical decline.

Traditional fall prevention emphasizes strength and balance, often overlooking cognitive factors. Yet, evidence shows that motor and cognitive systems are linked, and dual-task training can enhance both domains. Cognitive-motor training, which integrates cognitively demanding tasks into physical exercises, offers a promising dual-domain intervention by leveraging shared brain networks and promoting neuroplasticity.

While effective, most cognitive-motor programs are delivered in person and rarely tailored to individual frailty profiles. Personalized, home-based programs could offer better results through tailored challenge and engagement. Exergames, interactive digital games with physical and cognitive components, show promise as customizable, engaging tools for such training. However, few have integrated both domains simultaneously in frail adults.

This study aims to assess a 12-week, home-based personalized cognitive-motor training program against the Otago Exercise Program (OEP) in frail older adults. Outcomes include physical and cognitive fall-risk factors, fall incidence, quality of life, and physical activity. The hypothesis is that the personalized cognitive-motor program will lead to greater improvements and may offer an effective, scalable solution to reduce falls and promote independence in this vulnerable population.

Вмешательства

• Другое Personalized, home-based motor-cognitive exergame training
  The simultaneous cognitive-motor training in this study will be delivered using the exergame platform "Senso Flex" by Dividat (Dividat AG, Schindellegi, Switzerland), which is a pressure-sensitive foldable mat that connects to standard televisions (or any big screen). Games will be allocated across three primary domains: cognition (consisting of five sub-domains), balance (consisting of four sub-domains) and endurance. The five sub-domains of cognition are visuospatial orientation (Cognition A),
• Другое Otago Exercise Program
  Participants in the CG will receive the evidence-based OEP on fall prevention. The OEP was selected as an active control to mirror usual care in real-world clinical settings and support the pragmatic nature of our study design. The program will be implemented in the form of a booklet, designed to provide a comprehensive guide for improving balance, strength, and overall physical function. Specifically tailored for older adults, the program includes a variety of exercises targeting key areas such
