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.

超声引导富血小板血浆注射改善腰肌筋膜疼痛综合征的疼痛、功能和对称性：1例报告。

背景：肌筋膜疼痛综合征（MPS）是一种与肌筋膜触发点（MTrP）相关的常见肌肉骨骼疾病。肌肉损伤是MPS的常见病因之一。目前，MPS没有有效的治疗方法。病例总结：一名24岁女性腰方肌（QL）损伤并发慢性下背部MPS，采用有效的量表进行综合评估：疼痛严重程度（视觉模拟量表、McGill疼痛问卷）、功能残疾（Oswestry残疾指数、Roland Morris残疾问卷）和生活质量[SF-36]。客观评估包括双侧QL肌的肌电图、Myoton力学性能分析和磁共振成像体积测量。患者每隔4周接受4次超声引导富血小板血浆（PRP）注射，并在治疗后1、3、6个月进行随访评估。结论：超声引导下PRP注射可减轻创伤后MPS患者的疼痛，恢复功能，提高生活质量。肌电图显示mtrp影响肌肉的神经肌肉对称性恢复，支持PRP的治疗潜力。

期刊介绍： The World Journal of Clinical Cases (WJCC) is a high-quality, peer reviewed, open-access journal. The primary task of WJCC is to rapidly publish high-quality original articles, reviews, editorials, and case reports in the field of clinical cases. In order to promote productive academic communication, the peer review process for the WJCC is transparent; to this end, all published manuscripts are accompanied by the anonymized reviewers’ comments as well as the authors’ responses. The primary aims of the WJCC are to improve diagnostic, therapeutic and preventive modalities and the skills of clinicians and to guide clinical practice in clinical cases.
