Reliability and Validity of the Modified Heckmatt Scale in Evaluating Muscle Changes With Ultrasound in Spasticity
Bibliographic record
Abstract
OBJECTIVES: To determine the reliability and validity of the Modified Heckmatt scale in assessing muscle echotexture in spasticity. DESIGN: Prospective, observational, 2-center study. Two residents and 2 ultrasound experienced staff physicians each rated 100 ultrasound images that were also analyzed using quantitative gray-scale. SETTING: Academic ambulatory spasticity clinic. PARTICIPANTS: Participants (N=50) included 45 patients with upper or lower extremity spasticity and 5 healthy references. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Modified Heckmatt scale ratings and quantitative gray-scale scores. RESULTS: <.001). CONCLUSIONS: The Modified Heckmatt scale demonstrated good reliability and validity to assess the pathologic muscle changes that occur in patients with spasticity.

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.
