This study will be conducted in a hospital in Spain to investigate how a special intervention using immersive virtual reality technology can benefit hospitalized older adults with difficulties in their daily functionality. The main objective of this study is to evaluate whether a cognitive stimulation intervention through immersive virtual reality, along with specific physical exercises, can improve the cognitive and physical function of hospitalized older patients. It is expected that this innovative intervention will have a positive impact on the quality of life of these patients. Participants eligible for the study must be over 75 years old, have severe functional dependency upon hospital admission, and be willing to participate. Those with severe dementia or other terminal illnesses will be excluded. Participants will be randomly assigned to one of four study groups: a control group without intervention and three intervention groups, including viewing Spanish landscapes through virtual reality, performing specific physical exercises, or a combination of both interventions. At the end of the study, various aspects such as cognitive and physical function, mood, quality of life, muscle strength, and acceptance of virtual reality technology by patients will be evaluated. This study aims to provide new insights into the care of hospitalized older adults and explore innovative ways to improve their well-being during their hospital stay
