Dataset for: Eating Utensil Design for Older Adults: Effects of Handle Diameter and Mass Placement on Static Holding Stability and User Experience

The thick handle produced lower resultant acceleration variability in the targeted analysis, although this effect did not survive the broader six-effect Holm sensitivity correction. Distal mass placement increased exploratory 3–12 Hz relative gyroscope power after multiplicity correction, making proximal placement the more favorable configuration for this spectral endpoint. Participants generally perceived the thin handle as steadier but favored proximal mass placement.

Objective and perceived stability therefore diverged for handle diameter but converged for mass placement. The deposit is organized into a root-level questionnaire file, a stepwise analysis notebook, and the `Kinematic_Data` directory, which preserves the kinematic workflow from the original IMU recordings through processed signals and final participant-level and inferential outputs. The accompanying README documents the condition codes, questionnaire fields, processing rules, software environment, and interpretation limits.
