Systematic analysis of clinical deficits in unilateral hypoglossal nerve palsy
Bibliographic record
Abstract
INTRODUCTION: The clinical characteristics of unilateral hypoglossal neuropathy have not been systematically analyzed. METHODS: We documented subjective abnormalities of speech and swallowing, and photographed 9 specific tongue movements and positions. Objective deficits were scored independently by 2 examiners. RESULTS: Eight patients were analyzed. Some degree of dysarthria and dysphagia was noticed by 7 and 8 patients, respectively, mostly resolving within a few months. In all subjects, there was contralateral deviation of the tongue at rest and ipsilateral deviation upon forward protrusion. Furthermore, 7 of 8 patients had deficits in using the tongue to indent the ipsilateral cheek and cover the upper lip. CONCLUSIONS: Unilateral hypoglossal nerve palsy produces mostly subtle and transient patient symptoms, even when complete. Beyond the classic sign of ipsilateral deviation on protrusion, reliable signs are contralateral deviation at rest, paresis of ipsilateral movement inside the mouth, and paresis of elevation of the tongue tip.

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.
