Abstract

fetched live from OpenAlex

Impaired walking function following stroke leads to long-term disability and reduced participation in daily activities (1,2). The present study highlights the importance of evaluating dynamic stability during gait to provide insight on functional abilities and identify those at a higher risk of falling. The objectives included comparing centre of pressure (COP) parameters between the paretic and non-paretic limbs during the single support phase, and relating step-to-step variability in COP parameters to the severity of sensorimotor control impairment. Stroke survivors walked at their preferred and fast speed over a pressure sensitive mat. The results demonstrated an asymmetrical anterior-posterior (AP) COP displacement in favour of the non-paretic limb. A modification in forward progression was demonstrated by delays in advancing the COP over the foot. Step-to-step AP-COP displacement variability under the paretic limb was negatively associated to sensorimotor control. This work emphasizes the importance of evaluating dynamic stability during post-stroke gait performance.

Not 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.
