Clinical Trial Summary

The purpose of this research study is to use a new imaging technique called Magnetic Resonance (MR) Elastography to create new imaging parameters to measure the mechanical properties of myofascial tissues that can be used to assess the impaired myofascial interface in myofascial pain syndrome (MPS).


Description:

This is observational research that aims to develop an MRI-based imaging technique (MRE) to quantitatively assess the myofascial tissue properties in healthy subjects and patients with relevant pain conditions. Healthy volunteers and patients with MPS will be recruited to undergo MRI along with MR elastography.

Outcome

Type Measure Description Time frame Safety issue
Primary The fascia plane mobility assessed by MR Elastography-based normalized octahedral shear strain (NOSS) measurements In response to an external shear force, the fascial layers that surround and separate muscles can deform or slide relative to each other, depending on the fascial plane's mobility. An adhesive interface that experiences a shear force will exhibit shear displacement continuity (i.e., small shear strain) across the interface, while a nonadhesive interface may slip rather than deform, which causes a discontinuity in displacement (i.e., large shear strain). For the targeted fascia plane in low back and legs, the normalized octahedral shear strain (NOSS) will be computed from the shear displacement data measured from MRE to assess the fascia plane mobility. The primary outcome measure is the difference in the fascia plane mobility on MR elastography between patients with myofascial-related pain diseases and healthy controls without myofascial-related pain diseases. baseline measures through the study completion (3 years)
