Brain response to pain caused on arthritic knee selected by fMRI [ Time Frame: 4 months ] [ Designated as safety issue: No ]

Functional magnetic resonance imaging (fMRI) is particularly suited to investigating the effects of pharmacological agents on pain processing within the human central nervous system.

The measures are based on the haemodynamic resonse to a neuronal event and constitute indirect measures of excitatory and inhibitory neuronal activity. The neuronal activation is associated with an increase of the oxygen extraction fraction from the capillaries and with an increase in regional cerebral blood flow. The measure which derived from blood oxygenation is called the BOLD effect.

Assessment of the Effects of Chondroitin Sulphate in Patients With Knee Osteoarthritis With Functional Magnetic Resonance Imaging (fMRI)
Randomized, Double-blind, Placebo-controlled Study to Asses the Effect of Chondroitin Sulphate in Patients With Knee Osteoarthritis by Functional Magnetic Resonance Imaging

The main purposes of this study are:

  • to determine the effects of chondroitin sulphate on brain response to pain assessed through fMRI in patients with knee osteoarthritis.
  • to investigate the relationship between treatment response detected by fMRI and the results of the different parameters of clinical assessment.
