New imaging tests aim to pinpoint the source of mysterious muscle pain
NCT ID NCT06803056
First seen Jun 24, 2026 · Last updated Jul 02, 2026 · Updated 2 times
Summary
This study is working to create a reliable imaging test to find and measure problem areas in muscle and fascia tissue, known as myofascial pain. Researchers will use ultrasound and MRI to identify unique 'biosignatures' in 120 people with plantar fasciitis, Achilles tendinopathy, or healthy tissue. The goal is to improve diagnosis and enable more personalized treatment for these common pain conditions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Diagnostic tests (clinical exam and ultrasound/MRI imaging)
- What this could lead to
- If successful, this could lead to better, more personalized diagnosis and treatment for myofascial pain conditions like plantar fasciitis and Achilles tendinopathy.
- What could go wrong
- This is an early-stage diagnostic study, not a treatment trial. The imaging biomarkers being developed may not prove accurate enough for widespread clinical use.

Inclusion criteria for plantar fasciitis group: * Clinical diagnosis of plantar fasciitis * Duration of plantar fasciitis pain greater than or equal to 3 months * Severity of plantar fasciitis pain greater than or equal to 3/10 Inclusion criteria for Achilles tendinopathy group: * Clinical diagnosis of insertional Achilles tendinopathy: * Duration of Achilles tendinopathy pain greater than or equal to 3 months * Severity of Achilles tendon pain greater than or equal to 3/10 Control group: • Similar age, sex, and BMI as plantar fasciitis and Achilles tendinopathy groups Exclusion criteria: * Younger than 18 years of age * History of an invasive procedures to the foot and ankle on the side of interest * History of lower extremity injections, dry needling, or EPAT/ESWT within past 3 months on the side of interest * Contraindications for MRI (e.g. non-MR compatible implanted devices, claustrophobia, inability to remain still comfortably for 1 hour in a supine position, body size too large for MR scanner) * Clinically unstable medical or psychiatric issues * Pregnant or possibly pregnant * Co-morbidities associated with changes in musculoskeletal imaging, including: Diagnosed systemic conditions affecting the foot and ankle (e.g., rheumatoid arthritis, spondyloarthropathy, gout) endocrine disorder with complications (e.g., uncontrolled Type I or II diabetes, diabetic peripheral neuropathy) Neuromuscular diseases (e.g., Charcot-Marie-Tooth (CMT) disease) Connective tissue disorder (e.g. Marfan's syndrome, Ehlers-Danlos) Osteoarthritis of the foot or ankle History of foot or ankle fracture Infection of the foot or ankle (e.g., infectious fasciitis, calcaneal osteomyelitis) within the past year Familial hypercholesterolemia Neoplasms involving the foot, Plantar fibromatosis * Control group only: Persistent or recurrent leg pain in the past 6 months * Plantar fasciitis and Achilles tendinopathy groups only: Other source of heel or foot pain (e.g., tarsal tunnel syndrome, peripheral neuropathy, lumbar radiculopathy, calcaneal stress fracture, Morton's neuroma, fibromyalgia) or co-occurring plantar fasciitis and Achilles tendinopathy (for the Achilles tendinopathy group).
