A Descriptive Study of 100 Patients Undergoing Palliative Nerve Blocks for Chronic Intractable Headache and Neck Ache
Bibliographic record
Abstract
OBJECTIVE: To ascertain whether repeated (palliative) nerve blocks over a long period of time provide benefit to patients with chronic intractable headache and neck ache. SUBJECTS AND METHODS: One hundred patients who were receiving repeated nerve blocks as part of their pain management regimen completed a structured interview questionnaire. The patients had all been investigated and received a diagnosis of cervicogenic headache. Changes in pain rating, depression rating, anxiety rating, activities of daily living and quality of life were measured. RESULTS: After each nerve block session, the subjects reported significant improvement in their levels of pain, depression and anxiety. They also reported improvements in their quality of life and in their ability to participate in activities of daily living. CONCLUSIONS: Repeated (palliative) nerve blocks appear to be a useful modality in the armamentarium of pain control techniques for patients with chronic intractable headache and neck ache of cervical origin.

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.
