Neuroinflammation in carpal tunnel pain

The role of neuroinflammation in human peripheral neuropathic pain

NIH-funded research Massachusetts General Hospital · NIH-11286773

This project uses PET/MR scans with a special tracer to look for inflammation in the brain and spinal cord of adults with carpal tunnel syndrome compared with healthy volunteers.

What this research studies

If I join, I'll have a clinical exam and combined PET/MR brain and neck scan using the tracer [11C]PBR28 to look for signs of glial-driven inflammation. The team will scan about 80 people with carpal tunnel syndrome and 20 healthy volunteers, and patients will be scanned again after carpal tunnel release surgery. They will also collect nerve conduction tests, pain and function measures, and hand motor tests to link imaging findings with symptoms and nerve damage. The goal is to see where inflammation appears and whether it changes after surgery.

Who could benefit from this research

Good fit: Adults (21+) with diagnosed carpal tunnel syndrome, especially those able and willing to undergo PET/MR scanning and carpal tunnel release surgery, are the ideal candidates.

Not a fit: People without carpal tunnel syndrome, those unable to have PET/MR (for example due to implanted devices or pregnancy), or those not planning surgery are unlikely to benefit directly from participation.

Why it matters

Potential benefit: If successful, this work could show that specific inflammatory changes relate to neuropathic pain and help guide new anti-inflammatory treatments or predict who benefits from surgery.

How similar studies have performed: Prior PET studies using the same tracer have detected glial activation in chronic pain and neurodegenerative disorders, but using these signals to change patient care is still emerging.
