ClinConnect Summary

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.

Eligibility criteria

• Healthy Volunteer Inclusion Criteria:
• • Absence of a history of chronic pain in the targeted anatomical location (i.e., lower back and low extremities) that had limited activities of daily living or work
• • A numerical current pain index of less than 0.5 (on a 10-point Visual Analog Scale)
• • Able to understand the goal of the project and give informed consent.
• Healthy Volunteer Exclusion Criteria:
• • Pregnancy or breastfeeding
• • Any contraindication to an MRI exam
• • Previous severe/acute back or low extremity injury (including fracture)
• • Previous back or low extremity surgery
• • Back and lower limb deformities
• • Inability to provide consent.
• Myofascial-Related Pain Patient Inclusion Criteria:
• • A history of chronic low back or leg pain (the targeted location will be determined based on the findings in Aim 1) for at least 3 months. (Measured by patient history and physical exam)
• • A palpable taut band or nodule within the skeletal muscle
• • Hypersensitive tender spot within the taut band
• • Recognition of current pain complaint by pressure on the tender nodule/taut band
• • Painful limit to the full stretch range of motion
• Myofascial-Related Pain Patient Exclusion Criteria:
• • Pregnancy or breastfeeding
• • Any contraindication to an MRI exam
• • Previous therapy in the area to be treated within 6 months
• • Previous severe back or low extremity injury (including fracture) or surgery
• • Any neurological conditions or active systemic disease (e.g. diabetes, peripheral vascular disease, cancer, rheumatoid arthritis) that impaired sensation/pain perception
• • Severe osteoarthritis
