Ultrasound features of myofascial trigger points: a multimodal study integrating preliminary histological findings from the upper trapezius

Sci Rep. 2025 Jul 1;15(1):20510. doi: 10.1038/s41598-025-05869-2. ABSTRACT This study investigated the ultrasound and histological characteristics of myofascial trigger points (MTrPs) in the upper trapezius (UT) following dry needling (DN) therapy. Forty-nine participants with active MTrPs in one UT were included, with the contralateral healthy side serving as control. Ultrasound assessments (UT thickness, Young’s modulus, […]
