Impact of a mobile application and assistive chopsticks on traditional chopstick manipulation: an exploratory consecutive controlled case series with user-informed development

Integrating a vision-based app with ergonomically designed assistive chopsticks proved feasible, usable, and culturally meaningful. Although qualitative improvements were seen in nearly all participants, quantitative metrics detected fewer changes, indicating the need to refine analytic sensitivity. This combined approach shows promise for technology-assisted rehabilitation.
