MR(Magnetic Resonance) Imaging of Neurotransmitters in Chronic Pain

2018年5月31日 更新者：University of Michigan

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.

详细说明

This study will identify clinical and neuroimaging markers in chronic pain in an effort to provide individual-based treatments. This study will differentiate chronic pain subjects (knee osteoarthritis, low back pain and painful diabetic neuropathy) into two groups: those who have central pain predominant symptoms and those who have peripheral pain predominant symptoms. The response to medical treatment between these two groups is quite different, thus a reliable strategy to correctly categorize chronic pain sufferers offers the opportunity to provide targeted, effective treatments. Chronic pain is a prevalent problem in the VA veteran population with significant associated costs; in particular knee osteoarthritis, chronic low back pain and painful diabetic neuropathy are common in this population. The proposed study will use different clinical pain tests and advanced neuroimaging techniques to improve our understanding of chronic pain and improve patient outcomes.

  • 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)

  • Have primary complaint of constant or intermittent back pain of at least 6 months duration.
  • Have a Roland Morris Disability Questionnaire score of >7.

(Diabetes Mellitus with Painful Peripheral Neuropathy)

武器和干预

参与者组/臂
干预/治疗
实验性的：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.
其他：MRIs
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.
其他：Pain testing
There will be a 1-1.5 hour session including pain tolerance testing.
