    The Effect of Virtual Reality Applications on Balance and Gait Speed in Individuals With Alzheimer Dementia A Pilot Study
    (LIPPINCOTT WILLIAMS & WILKINS, 2020) Ugur, Fatma; Sertel, Meral
    Objective: The aim of the study is to investigate the effect of virtual reality applications on balance and gait speed in individuals with Alzheimer dementia. Method: The study consisted of 32 individuals diagnosed as mild or moderate Alzheimer dementia by the neurologist. The balance, fall risks, and gait speed were assessed. The training group was trained with games selected from different categories such as balance and aerobic exercises with Nintendo Wii virtual reality device for 6 weeks, 1 session of 30 minutes, 2 times a week. Results: The values of the 5-time sit-to-stand test and gait speed scores resulted that the training group had significantly lower scores than the control group. Tinetti balance score was decreased in the control group and increased in the training group. Conclusion: It is appropriate to add virtual reality applications to routine rehabilitation programs in order to increase patient's balance and gait speed in people with dementia. Clinical Identifier: NCT03928405

    Wii Fit Exercise's Effects on Muscle Strength and Fear of Falling in Older Adults With Alzheimer Disease: A Randomized Controlled Trial
    (Human Kinetics Publ Inc, 2024) Ugur, Fatma; Sertel, Meral
    Purpose: This study aimed to investigate how Wii Fit exercises affect muscle strength and fear of falling in older adults with Alzheimer's disease. Method: The study included a total of 32 volunteers with Alzheimer's disease, aged 65-80 years. These participants were divided into two groups: the exercise group and the control group. The exercise group received a 30-min (one session) twice-weekly exercise program for 6 weeks with games selected from different categories, such as balance and aerobic exercises, with the Nintendo Wii virtual reality device. During this period, the control group did not receive any treatment, and routine medical treatments continued. At baseline and 6 weeks later, Mini-Mental State Examination, knee extension muscle strength, Timed Up and Go Test, and Tinetti Fall Efficacy Scale results were recorded in the exercise and control groups. Results: In intragroup comparison, a statistically significant difference was found in all tests (muscle strength, Timed Up and Go Test, and Tinetti Fall Efficacy Scale) in the exercise group after the exercise program (p < .05), while no significant difference was found in the control group (p > .05). According to the interaction of group and time in the intergroup comparison, there was no difference between the groups (exercise and control group) in muscle strength and Timed Up and Go Test (p > .05), but there was a difference in Tinetti Fall Efficacy Scale (p < .05). Conclusions: This randomized controlled trial supports the claim that Wii Fit exercises can reduce the fear of falling in older adults with Alzheimer's disease.
