Clinical and neurological characteristics of patients with somatic referred back pain at the lumbosacral level
Bibliographic record
Abstract
Referred pain is a painful sensation in the peripheral regions during pathological processes in deep tissues or viscera. There are two types of referred pain: 1) somatic referred pain (from spinal structures to adjacent areas); 2) visceral referred pain (from pelvic and abdominal viscera). Patients and methods. The investigation enrolled 80 patients with nonspecific chronic and subacute lumbosacral spine pain. All the patients underwent standard neurological examination. Pain intensity was determined on a visual analog scale (VAS) using the DN4, PainDETECT, and short-form McGill questionnaires; the wind-up phenomenon was evaluated; the degree of muscular tonic syndrome was estimated applying the Khabirov questionnaire. The health-activity-mood (HAM), SF-36, and Roland-Morris questionnaires were used to assess quality of life. Results. Somatic referred pain was found in 62% of the examinees. In these patients, the clinical picture showed a set of characteristics for neuropathic (allodynia (31%), hyperesthesia (12%), and nociceptive (grades 1 and 2 muscular tonic syndrome 41 and 59%, respectively) pain; a high wind-up index was noted in 89% of the patients.

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.
