Autonomous Subjects, Aged 65 and Afraid of Falling
Conditions
Keywords
Fear of falling, Postural changes, Stand upright without technical assistance
Brief summary
The main aim of this study is to compare the fear of falling induced by each type of virtual scene (rocking and translation). Fear of falling will be assessed by a numerical fear of falling scale. The benefits for the participants would be the discovery of Virtuel Reality, the awareness of their fear of falling and its repercussions on posture and, if necessary, referral to specialized rehabilitation centers. This study will provide evidence on the context of the emergence of the fear of falling in order to propose, in perspective, appropriate rehabilitation management procedures.
Detailed description
This bicentric study will proceed as follows: * Complete clinical examination, carried out as part of your consultation in a day hospital. * Perform a virtual reality session of about 2 hours. This session will take place as follows: * Wear a virtual reality headset. The helmet is compatible with the wearing of glasses. * View a virtual scene for two minutes in order to familiarize yourself with the device. This first viewing will be followed by a 10 minute break. * Then the patient will be placed on a rectangular platform (Wii Balance Board - WBB) * Give the virtual reality headset again to the patient, who will view a 2-minute series of a series of 2 minutes in a standing position comprising a moving virtual environment (one tilting forward and another in forward translation). * After a 10 minute break, the session will continue with 4 other sets of 5 minutes duration (5 times 1 minute of a forward tilt or forward translation scene). These 4 series will be separated by 10 min break * During each break, the patient participating in the study will complete a questionnaire on the possible side effects of virtual reality (cybermalaise).

Intervention model description
Randomization will be carried out after inclusion and allocation of a selection / inclusion number of subjects and will be carried out as follows: * Subjects included and who will be identified with an even selection number will begin the virtual reality session by viewing a rocking environment followed by a translation environment * Subjects included and who will be identified with an odd selection number will start the virtual reality session by viewing a translation environment followed by a rocking environment
