IRCT20241018063403N2 IRCT 2025-01-26 Hamedan University of Medical Sciences vestibular rehabilitation on memory of elderly Investigating the effect of virtual- reality vestibular rehabilitation on Visio-spatial memory of elderly in Hamedan city 2025-05-22 anticipated 40 Complete https://irct.ir/trial/81495 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: Given that the subjects do not enter the study at the same time and the researchers cannot predict in advance which group each person entering the study will belong to, the random binary block method was used to assign the patients in the target group to one of the two study groups, using random allocation software to two groups that were the same in terms of age. In order to conceal the random assignment, the sealed opaque envelope method was used. In such a way that each of the random sequences created is recorded on a card and the cards are placed inside the envelopes in order. Finally, the envelopes are glued shut and placed in a box in order. At the time of participant registration, based on the order of the eligible participants entering the study, one of the envelopes is opened in order and the assigned group of that participant is revealed. N/A Cognition in elderly. Intervention 1: For virtual reality-based balance training, the Nintendo Wii Fit Plus device and its related games are used. This device has a balance board, handle, monitor, and receiver. The subject can interact with the games and instructions on the monitor through the balance board and control the game by performing physical activity. The elderly in the intervention group were required to attend 8 sessions (twice a week, 45 minutes each time) for a month to participate in vestibular rehabilitation sessions. Intervention 2: Control group: no intervantion.
