The Need for Three Separate Parallel WAD Ratings of Whiplash Injuries to Cervical, Lumbosacral, and Thoracic Spine in Clinical Assessments of Injured Motorists
Bibliographic record
Abstract
Background: The prevailing classification of whiplash associated disorder (WAD) focuses solely on neck injuries, thus implying that injuries to other spinal regions are relatively inconsequential. In fact, some whiplash studies exclude patients with injuries to lower spine. We examined whiplash pain locations of injured motorists and their statistical correlates. Method: De-identified archival data of 158 injured motorists (57 men and 101 women; mean age 39.4 years, SD=12.5) were reviewed statistically. Their motor vehicle accidents (MVAs) occurred 7 to 194 weeks previously (mean=50.7 weeks, SD=38.5), but all still experienced active whiplash symptoms requiring therapy. Results: The most frequently reported locations of whiplash pain were the head (89.9%), neck (88.6%), shoulders (80.4%), and lower back (77.8%). WAD studies that exclude patients with lower back pain might exclude about 82.9% of injured motorists: the remaining 17.1% of patients with whiplash injury only to the neck are presumably those less adversely affected by the MVA than patients with pain in multiple locations. No correlations of high or moderate magnitude were detected among the various pain locations. Furthermore, no high or moderate correlations were observed between clinical variables (including 2 neuropsychological symptoms scales) and reports of headache or pain in the neck or in lower back. Discussion and Conclusions: The prevailing WAD classification system needs to be renamed as specific to neck injury only: WAD-C. Parallel WAD classification systems need to be introduced separately for the lumbosacral spine (as WAD-LS) as well as the thoracic spine (as WAD-T) to improve diagnostic descriptive precision of clinical WAD assessments and of their research applications.

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.
