  Purpose

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.

Primary Outcome Measures:
  • Assessment of chronic pain [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 170
Study Start Date: September 2012
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: October 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Chronic Pain (MRI, surveys and pain testing)
Subjects previously diagnosed with Diabetic peripheral neuropathy, knee osteoarthritis or chronic low back pain will have an MRI with specific imaging during which brain metabolites will be assessed. There is a session of completing surveys and a session of pain tolerance testing.
Procedure: MRI, surveys and Pain 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 also be a 1-1.5 hour session of surveys and pain tolerance testing.
Active Comparator: Healthy controls (MRI, surveys and pain testing)
Healthy volunteers will have an MRI with specific imaging during which brain metabolites will assessed. MRI results will be compared to those metabolites in patients with chronic pain conditions. There is a session of completing surveys and a session of pain tolerance testing.
Procedure: MRI, surveys and Pain 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 also be a 1-1.5 hour session of surveys and pain tolerance testing.

Detailed Description:
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.
