Picture Sound Book with Ninja-Essence Targeting Older People Affected by the Fukushima Daiichi Nuclear Plant Accident: Development and Evaluation Before-After Pilot Clinical Trial

Abstract

Health and well-being are a major concern for the elderly who experienced evacuation due to the 2011 Fukushima Daiichi Nuclear Power accident. This study examined the feasibility of a picture sound book with Ninja-essence to maintain or improve exercise habits and physical and mental conditions of the elderly affected by the Fukushima Daiichi Nuclear Power plant accident. We conducted a pre–post intervention study to evaluate a picture sound book with Ninja-essence for returnees and evacuees post lifting evacuation restrictions. In total, 29 people participated in this study. Residents in two groups, returnees and evacuees, were provided with the tool. Results of the pre–post changes were analyzed using descriptive statistics, i.e., Fisher’s exact test and t-test, and a significant difference was observed in both groups of participants between their left and right hand-grip strength, the maximum phonation time in the participants of the group that regularly engaged in exercise, and in the questions regarding swallowing exercises and singing songs or practicing words (p < 0.013 and 0.033); 16 of 29 participants reportedly enjoyed the program. The results demonstrated the future possibility of determining the improved outcome of this program in larger samples.
