About

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

Full 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.

Enrollment: 52 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: Accepts Healthy Volunteers

Inclusion and exclusion criteria

Healthy Volunteer Inclusion Criteria:

2. A numerical current pain index of lower than 0.5 according to initial assessment with visual analog scale
3. Able to understand the goal of the project and give informed consent.

Healthy Volunteer Exclusion Criteria:

1. Pregnancy or breastfeeding
2. Contraindication to MRI
3. Previous severe/acute neck or shoulder injury
4. Previous neck or shoulder surgery

7. Pregnancy, coagulopathy, fever, general/local infection at the pain site, substance abuse, peripheral neuropathy, or any other diseases that may account for signs and symptoms mimicking myofascial pain
8. Contraindication to MRI.
