Impact de l’utilisation d’un dispositif de réalité virtuelle immersive sur le contrôle moteur lors d’un Timed Up and Go

Abstract : Risk of fall in the elderly is a major public health issue. Its early detection would make it possible to intervene before the first fall or prevent its recurrence by offering suitable preventive physical activity. However, the assessment of a fall risk with frequently used tests and scales is not fully satisfactory. Recent technological innovations in the field of immersive virtual reality suggest that its use in the assessment of fall risk could fill some gaps in contextualization and uniformity of current tests. However, before using these technologies in the fall risk assessment, it is important to know their impact on motor behavior. To do this, we chose to test a locomotor task, the Timed Up and Go (TUG - a clinical test widely used by clinicians and a real “gold standard” in the evaluation of the risk of falls in the elderly), in a real environment. and in a virtual environment with the elderly as well as young adults. Differences are observed with increases in time and number of steps in virtual reality. Thus, immersive virtual reality could be an avenue of choice in the assessment of the risk of falls by increasing the sensitivity and specificity of the tests since it allows to contextualize the test environment. However, this solution could only be temporary given the promises of mixed reality which would allow both to contextualize the test in the real environment with digital control of the constraints that can be added to this environment.
