Avoidance and Accommodation of Surface Height Changes by Healthy, Community-Dwelling, Young, and Elderly Men
Bibliographic record
Abstract
The purpose of this study was to compare avoidance and accommodation strategies during gait between healthy, community-dwelling, young and elderly males. Ten young (28.4 +/- 5.4 years) and ten elderly (69.5 +/- 6.1 years) males were tested while walking on the level, avoiding a 11.75-cm-high obstacle, and accommodating a change in floor height of 11.75 cm. Three dimensional, kinematic, and kinetic analyses were performed bilaterally. Both age groups used the same general sagittal plane strategies in order to avoid and accommodate the obstructions, but the elderly group had significantly reduced lead toe clearances. These riskier toe clearances by the elderly group were found to be due to limited, frontal plane pelvic motion, shorter stride lengths, and subtle differences in the interplay of lower limb energetic patterns within the sagittal plane. These results are discussed with respect to diminishing physical capacity in the elderly populations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
