Participants reported improvements in task performance and satisfaction. Regarding movement effectiveness, there was a 14.4% increase in the minute transport of solid food using the fork (p ≤ 0.05) and increases of 33.1% and 36% in the total and minute transport of liquid food using the spoon (p ≤ 0.05). Efficiency improvements included reduced task time and enhanced vertical velocity with the spoon (p ≤ 0.05) as well as increased mediolateral velocity with the fork (p ≤ 0.05). These findings suggest that the assistive cutlery prototype demonstrates good usability, enhances user satisfaction, and improves movement effectiveness and efficiency for PwPD.
