Abstract
OBJECTIVES: To evaluate the efficacy and safety of therapeutic electromagnetic fields (TEMF) on chronic low back pain. Secondary objectives included the investigation of the effects of TEMF on psychometric measures. SETTING: Pain Research center in an Urban Academic Rehabilitation Facility. DESIGN: Prospective, randomized, single-blind, placebo (sham) treatment-controlled design in which participants were evaluated over a 6-week period. A total of 40 subjects were randomly assigned: 20 subjects to 15 milliTESLA (mT) treatment using a prototype electromagnetic field device and 20 to sham treatment. INTERVENTIONS: After a 2-week baseline period, eligible individuals were randomized to one of the treatment groups (sham or 15 mT) for six 30-minute treatments over 2 weeks, then a 2-week follow-up period. OUTCOME MEASURES: The primary outcome measure was the self-report of pain severity using a 100 mm visual analog scale collected using a twice daily McGill Pain Questionnaire-Short Form. Several secondary measures were assessed. RESULTS: Both groups (15 mT and sham) improved over time (P < 0.05). Although groups were similar during the treatment period, treated subjects (TEMF of 15 mT) improved significantly over sham treatment during the 2-week follow-up period (20.5% reduction in pain; F(1,34) = 10.62, P = 0.003). There were no reported serious adverse events. CONCLUSIONS: This study demonstrates that TEMF may be an effective and safe modality for the treatment of chronic low back pain disorders. More studies are needed to test this hypothesis.

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 it
