start of 1:1-Block public summary

Brief Summary in Lay Language

Previous research leds to the assumption that emotional learning may play a major role in the development of
chronic pain. However whether these learning processes really predict persistent pain is still not very well known and the role of stress in these processes is also not clear. This will be the target of the present study investigating patients with subacute and chronic back pain and healthy controls. Besides psychosocial factors, activation in specific brain regions will also be assessd.

Brief Summary in Scientific Language

Previous research leds to the assumption that emotional learning may play a major role in the development of
chronic pain. While a number of
studies have shown that psychosocial factors predict persistent pain, little is known how these relate to altered
learning processes. Moreover, the changes in brain structure and function associated with learning mechanisms have not been examined in a longitudinal manner. Moreover, learning processes may interact with the experience of stress, which can alter pain processing and pain-related brain circuits.

Interventions/Observational Groups

  •   Observational study: Patients (investigation once, partly twice) - patients with chronic back pain perform different tasks (conditioning) at two measurement time points, depending on specific values regarding back pain (worsening in comparison to measurement time point 1)
  •   Observational study: healthy controls perform different tasks (conditioning) at one measurement time point

Primary Outcome

Questionnaires on pain (West Haven-Yale Multidimensional Pain Inventory), anxiety (State-Trait-Anxiety Inventory) and depression (Beck Depression Scale) and tasks (conditioning) will be obtained for each particiant at each measurement time point (measurement time points: 01.07.2015 - 30.06.2019)

start of 1:1-Block secondary endpoint

Secondary Outcome

Persons, in whom back pain gets worse, will be measured twice (1 year after the first measurement time point, 01.07.2016 - 30.06.2019) using the conditioning tasks
