Abstract
An abnormal gait is not uncommon in patients with medically unexplained neurological symptoms, including those with other psychogenic movement disorders (PMDs). Previous studies have not evaluated the gait characteristics of patients with a variety of PMDs and there are no reports comparing PMDs with and without gait disturbances. We were interested in determining how those with and without additional involvement of gait differed and how PMD patients differed from those with a pure psychogenic gait disorder (PGD) in the absence of another PMD. We investigated gait features in a large series of patients with PMD (n = 279), dividing them into two groups (Group I with a normal gait and Group II with an abnormal gait). Group I included those with PMD with a normal gait and no change in the PMD while walking (I-1), and those with a change in PMD while walking, but not affecting gait (I-2). Group II was divided into those with PMD with additional abnormal gait (II-1) and those with pure psychogenic gait disorder without other abnormal movements (II-2). Excessive slowing of movement was more common in PMD patients with an abnormal gait (Group II) compared to those without (Group I). Slowness of gait was the most common feature in patients with PMD combined with a PGD (II-1) and buckling of the knee pattern was the most common type of pure PGD (II-2), followed by astasia-abasia.

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.
