Impact of Attentional Loading and Task Constraints on Postural Control of Healthy Older Adults
Bibliographic record
Abstract
Postural control is attention demanding, and it may be jeopardized when a secondary cognitive task is involved, particularly for older adults. The magnitude of this interference depends on different individual (perceptuo-motor status), task (single vs. dual tasking), and environmental constraints (support surface). The purpose of this research was to examine if older adults may be affected by various types of secondary cognitive tasks, while maintaining quiet standing on different support surfaces. In line with conceptual models, the results indicated that postural control of older adults was compromised when they were required to dual-task, especially when the support surface was challenging. This was a robust finding across all the measures of COP. In regards to the degree to which different attentional tasks affected postural control, the results remained equivocal. From a practical standpoint, the results indicated that older adults should exhibit caution when simultaneously performing a balance and a cognitive task involved particularly when the surface is unsteady.

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.
