Abstract
Background and Objectives Aging suits are widely used as arguably didactic tool to foster understanding for age-related challenges in healthcare training by mimicking physical impairments associated with aging. However, effects on functional levels are ambiguous and necessitating validation of their potential to simulate age-related walking impairments. We evaluated effects of wearing an aging suit on kinematic gait variables, in younger and middle-aged adults in different walking conditions. Available reference data were used to compare aging-suit induced effects to standard and dual-task walking in older adults.Research Design and Methods Whole-body kinematics (sagittal ankle-, knee-, hip-angles, arm-swing, trunk-bend) and spatiotemporal parameters (walking speed, stride length, step width) were measured in 14 young (20–34 years) and 15 middle-aged adults (40–63 years). SPM analysis and mixed ANOVA were conducted to evaluate the effects of the suit, age-group and their interaction.Results Overall, wearing the aging suit changed gait patterns, but kinematic parameters were hardly affected in both groups. During standard walking, arm-swing decreased by 17%, walking speed by 9%, and step width increased by 15% across both groups. Compared to reference data, changes in arm-swing corresponded to an instant aging effect of 45–55 years in young and 15–25 years in middle-aged adults.Discussion and Implications The aging suit changed gait patterns considerably making both groups walk more cautiously compared to reference values of older adults. However, performance deficits seen in individuals 80+ years were clearly not attained. Caution is advised when using aging suits as an educational tool to simulate age-related walking impairments.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
