Brief Summary:
This study will look at the short-term effect of morphine on brain response to food.

Condition or disease Intervention/treatment Phase
Chronic Low-back Pain Drug: Morphine Phase 4

Detailed Description:
Chronic low back pain patients and healthy controls will be recruited for this study. Participants' brain will be scanned at baseline and then again on a different day after the administration of an oral dose of 30 mg morphine in an open label design. Participants will receive morphine 60 minutes prior to the start of the second scanning session. The brain scans will include structural scans, functional scans at rest and functional scans during the ingestion of a highly caloric drink.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. mean change in subcortical brain structure volume [ Time Frame: baseline to 1 hour ]
    Magnetic Resonance Imaging (MRI) scanning was performed to collect brain volume measurements in cc.

  2. mean change in brain response to highly caloric drink [ Time Frame: baseline to 1 hour ]
    Participants received a highly caloric drink and a tasteless solution during a functional MRI scanning session. General linear model was used to generate the magnitude of the fit for each type of stimuli and differences between the fits were calculated. Next within subject analysis approach was used to calculate the effect of an acute dose of morphine on brain response to the highly caloric drink between baseline and 1 hour. The measures of the fit and their differences are expressed in z-scores.

  3. mean change in resting brain activity [ Time Frame: baseline to 1 hour ]
    Participants were scanned at rest during a functional MRI session.


Secondary Outcome Measures :
  1. mean change in back pain intensity [ Time Frame: baseline to 1 hour ]
    Pain was rated using a visual analog scale ranging from 0-100 with 100 indicating the worst imaginable pain ever.
