Synopsis

Keywords: Muscle, Elastography, slip interface imaging, myofascial interface, myofascial pain syndromeMyofascial pain syndrome (MPS) is a common chronic pain disorder that can cause disability. Efforts to understand the MPS pathology have focused on myofascial connective tissue and the function of fascial plane mobility. Slip interface imaging (SII) offers a unique opportunity to assess fascial plane mobility noninvasively. Here, we investigated the feasibility of SII to visualize the mobility of the intermuscular myofascial interface in the upper leg and the functional intramuscular interface in the forearm flexor muscles in healthy volunteers. This creates a foundation for using MRE/SII to distinguish between a healthy and a dysfunctional fascial plane in MPS patients.
