Ultrasound-guided platelet-rich plasma injection improves pain, function and symmetry in lumbar myofascial pain syndrome: A case report
Bibliographic record
Abstract
BACKGROUND: Myofascial pain syndrome (MPS) is a common musculoskeletal disease associated with myofascial trigger point (MTrP). Muscle injury is one of the common causes of MPS. Currently, there is no effective treatment for MPS. CASE SUMMARY: A 24-year-old female with chronic lower back MPS secondary to quadratus lumborum (QL) injury underwent comprehensive evaluation using validated scales: Pain severity (visual analog scale, McGill Pain Questionnaire), functional disability (Oswestry Disability Index, Roland Morris Disability Questionnaire), and quality of life [short form 36 (SF-36)]. Objective assessments included sEMG of bilateral QL muscles, Myoton mechanical property analysis, and magnetic resonance imaging volumetric measurements. The patient received four ultrasound-guided platelet-rich plasma (PRP) injections at 4-week intervals, with follow-up evaluations conducted at 1, 3, and 6 months post-treatment. CONCLUSION: Ultrasound-guided PRP injections alleviated pain, restored function, and improved quality of life in post-traumatic MPS. sEMG demonstrated neuromuscular symmetry restoration in MTrP-affected muscles, supporting the therapeutic potential of PRP.

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.
