MR(Magnetic Resonance) Imaging of Neurotransmitters in Chronic Pain
MR (Magnetic Resonance) Imaging of the Excitatory and Inhibitory Neurotransmitters in Chronic Pain
This study is designed to assess:
Hypothesis #1: That there is a significant central pain component in a distinct subset of patients diagnosed with knee osteoarthritis(KOA), Chronic low back pain(CLBP), painful diabetic neuropathy(PDN.)
Hypothesis # 2: To establish a reliable strategy for differentiation of central pain predominant from peripheral pain predominant knee osteoarthritis(KOA), chronic low back pain(CLBP)and peripheral diabetic neuropathy(PDN) patients using clinical features, experimental pain testing and magnetic resonance(MR) Spectroscopy.

- Diagnosed with: unilateral, symptomatic knee osteoarthritis based on American College of Rheumatology (ACR) criteria.
- Have had a knee x-ray within the last 6 months.
- Must have average pain intensity of 4 or greater on a 0 (no pain) to 10 (worst pain imaginable) scale.
(Chronic Low Back Pain)

実験的:Knee osteoarthritis (MRI, surveys, pain testing)
Subjects previously diagnosed with knee osteoarthritis will have an MRI with imaging that measures brain metabolites.
There are surveys to complete and a session of pain tolerance testing.
|
Subjects will have an MRI scan to view specific images, and brain activity patterns thought to be affected in patients with KOA, chronic low back pain and diabetic patients with painful neuropathy.
Healthy volunteers will undergo the same MRI scan that lasts about 90 min.
There will be a 1-1.5 hour session including pain tolerance testing.
