Chronic non-specific low back pain accounts for 95% of cases of low back pain and is characterized by a defined ethology and the presence of symptoms for at least 12 weeks. In an attempt to reduce the impact associated with chronic non-specific low back pain certain treatments have been recommended. One of the approaches for therapy is the cognitive behavioural model.
This assumes that disability is determined not only by the underlying pathology, but also by social, cognitive, emotional, and behavioural factors. The graded activity program, based on the cognitive behavioural therapy was developed based on studies suggesting that cognitive-behavioural aspects and operant conditioning principles can be used to reinforce healthy behaviours.
