Prevention Methods for Senior Falls

This paper deals with the primary factors and countermeasures to prevent falls in seniors in an aging society. Falls among seniors are emerging as a serious social and economic problem, leading to psychological trauma, physical injuries, long-term disabilities, fatalities, and increased medical costs. Therefore, fall prevention is essential for improving an individual’s quality of life and reducing social costs. This study aims to analyze the key physical factors contributing to elderly falls and propose practical strategies for their prevention. To achieve this objective, the study addresses the following research questions: First, what are the differences in impact forces between linear and rotational motion during falls? Second, how can the relationship between impact duration and impulse be quantitatively assessed in relation to actual injury risk? To answer these questions, a physical analysis was conducted by categorizing seniors’ fall types into linear and rotational falls, utilizing linear and angular momentum principles and impact force calculations. The impact force was determined using the law of energy conservation and momentum change, and a simulation was performed using Pygame to validate the theoretical findings. Based on the results, this paper aims to contribute to developing effective fall prevention measures and establish a stronger social foundation to ensure a safer and healthier aging society.
