乾針治療斜方肌筋膜疼痛的影像與組織學探討：中西醫整合視角

肌筋膜疼痛症候群（MPS）在中醫屬「痹證」、「筋痹」、「經筋不利」範疇。2025年發表於《Scientific Reports》的研究結合多模態超音波與組織學分析，揭示激發點具有肌纖維萎縮、筋膜纖維化、局部缺血與免疫細胞浸潤之特性，並證實乾針可在短時間內改善組織硬度、厚度及血流灌注。本文以該研究為基礎，結合中醫經絡、經筋與氣血理論，從「筋膜為經筋之體」「氣血為痛症之本」的角度重新詮釋結果，提出乾針與針刺治療MPS的共同機轉，並指出筋膜可能為中醫經絡的現代解剖依據。

A recent study published in Scientific Reports has revealed that myofascial trigger points (MTrPs) of the upper trapezius involve increased tissue stiffness, fascial thickening, perfusion deficits, and neuroimmune activation through multimodal ultrasound and histological investigations. Dry needling (DN) produces immediate improvements in muscle elasticity, vascularity, and pain scores. Histology demonstrates muscle fiber atrophy, fibrofatty replacement, and collagen remodeling, without classical contraction knots. From a Traditional Chinese Mediciine (TCM) perspective, these pathological findings corrdspond to meridian obstruction, qi-blood stagnation, and dysfunction of the tendon channels. DN's therapeutic effects parallel acupuncture mechanisms such as activating blood, dredging meridians, and regulating qi. These insights suggest that fascia may serve as a modern anatomical correlate of the meridian-tendon system and provide a scientific goundation for integrating acupincture into fascia-based pain management.
