Fig. 2From: Reliability of muscle stiffness measures in popliteus, medial and lateral gastrocnemius muscles by ultrasound shear wave elastography in participants with knee osteoarthritis accompanied by myofascial trigger pointsA boxplot illustrates the median muscle stiffness assessed by each rater for three muscles (PM (popliteus muscles), GM (gastrocnemius, medial head), and GL (gastrocnemius, lateral head), as well as the minimum and maximum stiffness (range) measured by each rater, including any outliersBack to article page
