Development and Effectiveness of a Fall Prevention Video on Muscle Stretching Exercises through Group Learning via LINE Application among Older Adults in Muen Wai Subdistrict, Mueang District, Nakhon Ratchasima Province

Abstract

This research employed a quasi-experimental design with the objectives of developing a video-based fall prevention program using muscle stretching exercises for older adults, evaluating its effectiveness, comparing outcomes before and after the intervention, and examining the relationship between fall risk (Thai-FRAT) and muscle strength (SFT). The sample consisted of 52 older adults selected by simple random sampling, with sample size determined using G*Power software. Research instruments included a video media effectiveness evaluation form, the Thai-FRAT, and the Senior Fitness Test (SFT). Data were analyzed using descriptive statistics and inferential statistics, including paired t-tests, Pearson’s correlations, and Spearman’s correlations. The research results showed that the video program, developed based on the Analysis, Design, Development, Implementation, and Evaluation : (ADDIE) model, featured 12 stretching exercises designed to prevent falls. The overall appropriateness of the media was rated high (M=4.43, SD = 1.12), and its feasibility was also rated high (M= 4.07, SD = 0.52). After participating in group learning via the LINE application, the average muscle strength scores in six areas significantly improved (p < .001). Moreover, a moderate positive correlation was found between fall risk scores and the 2-minute step test (r = 0.450, p < 0.001) indicating that the video-based intervention effectively enhanced physical fitness and reduced fall risk among older adults. The findings suggest that the video can be effectively implemented in elderly schools in Muen Wai Subdistrict and similar communities as part of ongoing fall prevention practice. Future research should explore its adaptation for other target groups and investigate the development of additional digital communication innovations to expand the intervention’s impact.
