“…VR possesses a highly motivating multidimensional virtual environment that the user can interact with, which provides sensory feedback, thus allowing the individual to perform in activities or tasks comparable to real situations. The intensity and difficulty degree can be graded and provides the user with information about the reached objectives in real time [7][8][9][10]. There are different types of VR, including: immersive, in which the patient is fully integrated in the virtual environment and interacts with it through some type of hardware, such as data gloves or VR glasses, semi-immersive, in which the patient is visualised within the virtual environment through a screen and interacts with it through their movements or with some remote controller but without losing contact with the real world, and nonimmersive, in which the patient interacts with the virtual environment through a computer-generated character represented on a screen with a peripheral device controller [8,[11][12][13].…”

Background: Stroke patients with motor, sensory and cognitive diseases can take profits from information and communication technologies—in particular, from the latest commercial video consoles, which are based on motion capture. These technologies are positioning themselves as complementary therapeutic tools for treating gait and balance disorders. In this paper, a systematic review of the effect of video game-based therapy on balance and gait in stroke patients is shown and compared with other types of treatments. Methods: A systematic review of prospective controlled clinical trials published in the main biomedical databases in English and Spanish between 2005 and 2020 was performed. The systematic review presented in this paper has been done following the Cochrane Manual recommendations and the PRISMA Declaration by two independent reviewers. Data about participants, intervention, outcome measurements and outcome measurement results were extracted. The quality of evidence of each study was assessed using Cochrane’s standard quality assessment format, which includes a description of the risk of bias. Additionally, the Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of each paper. Results: A total of 18 papers, including 479 patients, were included in this systematic review, in which the use of video consoles (in combination with conventional rehabilitation or exclusively) was compared with conventional rehabilitation to treat balance or gait in post-stroke patients. In all studies, a tendency to improve balance was found in both intervention groups, finding, in 10 of 17 studies that analysed it, a better capacity in the experimental group that included video consoles compared to the conventional rehabilitation control group. Regarding gait, in six of seven studies that analysed it, improvements were found in both intervention groups, and these improvements were greater in the experimental group than compared to the control group in three of them. Conclusions: Commercial video game systems, in combination with conventional rehabilitation, have shown positive results on balance and gait in post-stroke patients. There were variations between the trials in terms of the video consoles used and the duration, frequency and number of sessions with commercial video games. Future studies should compare the effects of commercial video game treatments on balance and gait in stroke patients with a nonintervention group to know their real efficacy.

“…Dentro de esta categoría podemos encontrar la realidad virtual híbrida, la cual se conoce como una realidad aumentada que incorpora objetos gráficos virtuales en una escena real tridimensional 5 . En medicina, un claro ejemplo sería el reconocido sistema de simulación de ultrasonido de Heartworks, que permite evaluar aparatos de un simulador mientras el alumno realiza la exploración del mismo, generando habilidades para que el alumno pueda manipular de manera efectiva y correcta un estudio que es dependiente del operador 6 .…”

“…Morton Heilig se dedicaba a la cinematografía y sus trabajos eran muy reconocidos en todo el mundo; sin embargo, lamentablemente, Sensorama no logró conseguir apoyo financiero ni inversionistas para poder ser globalizado. Su idea era muy prometedora, pero en ese momento se presentaban eventos tan importantes como la llegada del hombre a la Luna, que la eclipsaron totalmente 6 . Posterior a esto, entidades como la NASA o la US Air Force crearon su realidad virtual para poder entrenar a sus pilotos, modo de enseñanza que hoy cubre casi el 80% de sus tareas curriculares.…”
