Back School or Brain School for Patients Undergoing Surgery for Lumbar Radiculopathy?

The primary scientific objective of the study entails examining whether perioperative pain neuroscience education (PPNE or \'brain school\') is more effective than classical back school in reducing pain and improving pain inhibition in patients undergoing surgery for spinal radiculopathy. A secondary objective implies examining whether PPNE is more effective than classical back school in imparting a behavioural change (i.e. decreasing postoperative healthcare expenditure for lumbar radiculopathy), improving functioning in daily life and improving surgical experience (=better prepared for surgery, surgery meeting their expectations) in patients undergoing surgery for spinal radiculopathy.
