Abstract

fetched live from OpenAlex

Background: Degenerative cervical myelopathy is a debilitating condition of the spinal column resulting in a progressive, clinically measurable loss of motor and sensory function secondary to spinal cord compression. We sought to correlate the patient’s subjective experience of specific myelopathic impairments with components of the objective clinical exam, to determine if the latter provides any clinically-relevant information postoperatively. Methods: Thirty-eight myelopathy patients consented to complete the mJOA questionnaire and receive a physical exam preoperatively, and 6-weeks and 6-months postoperatively. mJOA components were correlated with the physical exam using Spearman correlations with an alpha of 0.05. Results: mJOA scores for sensation and lower limb motor function correlated with the sensory and lower limb motor exams respectively, both preoperatively and 6-weeks postoperatively. mJOA scores for upper limb motor function did not correlate with the upper limb motor exam at either timepoint. Conclusions: At baseline and immediately postoperatively, patients self-report sensation and lower limb motor function accurately. However, the patients’ subjective experience of upper limb motor function does not align with clinical exam findings, suggesting either a continued need for this component of the physical exam or a need for tools that better correlate with the patient’s experience of upper limb motor impairment.

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.
