Abstract
This study investigates the impact of two toilet seat modes, general and preferred, on transfer stability for individuals with mobility disabilities. The main objective is to determine if the preferred mode, tailored to individual needs and preferences, provides better stability compared to the general mode. The research involved simulated toilet transfer trials with participants who can ambulate but have a mobility disability. The Center of Pressure (COP) on the toilet seat was calculated using the force results from four load cell sensors, and an ellipse was generated to bound the movement of the user's COP. Statistical analysis and machine learning techniques were employed to analyze and compare the ellipse areas in the general and preferred mode trials. Descriptive statistics indicated a trend of higher ellipse areas in the preferred mode trials, but the Mann-Whitney U test and Cliff's delta results revealed no statistically significant difference between the ellipse areas for the two modes. This study provides valuable insights into the factors affecting stability during toilet seat usage and transfers, and highlights the potential of machine learning algorithms for enhancing stability and safety for users, especially older adults and individuals with disabilities.
