Fully-immersive virtual reality instrumental activities of daily living training for mild dementia: a feasibility study

Abstract

Background: The purpose of this study was to confirm whether fully-immersive virtual reality instrumental activities of daily living training is safe and feasible for people with mild dementia.

Methods: The virtual reality program contents include simulation of instrumental activities of daily living training. Feasibility was assessed by means of responses to a self-report satisfaction questionnaire and the Simulator Sickness Questionnaire; and by analyzing the level of participants' immersion. Researchers assessed the instrumental activities of daily living scores, cognitive functioning, and mood changes pre- and post-intervention.

Results: A total of seven participants with mild dementia were recruited. The mean immersion score was 50.42±7.89 points, and the mean adherence was 83.71±6.10 points. Overall, the participants found the activities satisfying. Six participants experienced negligible side effects and one exhibited moderate side effects. After the training, the instrumental activities of daily living scores improved significantly (P=0.042). Performance on the Word List Delayed Recall test and Trail Making Test B showed improvements in all participants.

Conclusions: Fully-immersive, virtual reality-based, instrumental activities of daily living training is feasible for people with mild dementia and provides them with a high level of satisfaction and immersion. This program can help improve their capacities to carry out activities of daily living, their cognitive functioning, and mood. However, further research is needed for fully-immersive virtual reality instrumental activities of daily living training before it can be considered as a treatment option in people with mild dementia.
