Impact of cognitive impairment on the upper limb function recovery after lacunar stroke
Bibliographic record
Abstract
The purpose of this study was to evaluate impact of cognitive impairments on the upper limb function recovery after acute lacunar stroke (LS). Material and methods. 139 patients (aged from 35 to 80 y. o.) with acute LS were examined. Along with the clinical and neurological examination, an upper limb function was evaluated by Action Research Arm Test and 9-Hole Peg Test, a study of cognitive status was made using the Montreal Cognitive Assessment (МоСа) and Frontal Assessment Battery (FAB). Results. Impaired upper limb function was revealed in 79% of patients with LS. After 2 weeks of acute period of LS, a significant improvement or the complete recovery of the upper limb function was observed in 81%. Moderate/severe executive dysfunction (FAB < 15 points) was defined in 65% of patients with LS and upper limb dysfunction. Moderate/severe cognitive impairments (МоСа < 26 points) were revealed in almost 55% of patients. In acute period of LS, the negative prognostic factor for complete recovery or significant improvement of the arm function was the presence of moderate/severe executive dysfunction (OR 3.89; 95% CI 1.07-14.19; p = 0.04) and general cognitive deficit (OR 3.27; 95% CI 1.10-9.70; p = 0.03). Conclusions. Cognitive impairments including executive disorders may affect the upper limb function recovery in acute period of LS. The data obtained can be used for the development of personalized rehabilitation programs for these patients.

How this classification was reachedexpand
Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
