Multi-modal Imaging of Myofascial Pain

August 31, 2026 updated by: Washington University School of Medicine

Development and Identification of Magnetic Resonance, Electrophysiological, and Fiber-optic Imaging Biomarkers of Myofascial Pain

The goal of this study is to develop new imaging biomarkers for quantitative assessments of myofascial pain.

Study Overview

Detailed Description

This study aims to develop a multi-modal, multi-parametric, multi-scale imaging of the human myofascial unit by combining magnetic resonance imaging (MRI), surface electromyography (sEMG), and fiber-optic imaging and sensing.

Participants (half with active neck/shoulder/back pain, and half healthy controls) will be recruited from pain management clinics and Volunteer for Health, or will be referred by Dr. Xioabin Yi. They will undergo all three imaging techniques and complete a number of patient questionnaires over the course of a single study visit. The study team will then identify candidate biomarkers capable of differentiating between healthy (no myofascial pain) and those with active pain to target in a future clinical trial.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Multi-modal imaging of myofascial pain
Participants with and without myofascial-related pain disease will receive multi-modal, multi-parametric, multi-scale imaging, including magnetic resonance imaging, surface electromyography, and fiber-optic imaging and sensing.
Study Participants will undergo four study procedures at one visit, including magnetic resonance imaging (MRI), surface electromyography (sEMG), fiber-optic imaging and sensing, and questionnaires.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Statistical Plan
Time Frame: For each individual, multi-modal imaging will be performed on the same day. Magnetic Resonance Imaging (MRI) will take about 1 hour. Fiber-optic measurements will take a few minutes. Surface electromyography (sEMG) recording will take <20 minutes.
The statistical analysis will assess the capability of imaging-based quantitative biomarkers to distinguish the pathological and physiological differences between participant groups (i.e., myofascial pain patients vs. healthy volunteers). The imaging biomarkers will be measured for each participant, including tissue stiffness, hydration, inflammation, blood oxygenation and flow, electrical activity, etc. The biomarkers will be measured and compared in the univariate fashion, which means we assess the differentiation performance for each biomarker independently. For each biomarker, we will compare the difference between the participant groups, using the Student's t-test or Wilcoxon rank-sum test. The statistical power will be estimated based on the effect size (Cohen's d) of difference between the participant groups. With an expected effect size of >0.9, the proposed sample size can achieve a statistical power greater than 0.8.
For each individual, multi-modal imaging will be performed on the same day. Magnetic Resonance Imaging (MRI) will take about 1 hour. Fiber-optic measurements will take a few minutes. Surface electromyography (sEMG) recording will take <20 minutes.
