Efficacy of Classification Based 'Cognitive Functional Therapy' in Patients With Non Specific Chronic Low Back Pain

Efficacy of Classification Based 'Cognitive Functional Therapy' in Patients With Non Specific Chronic Low Back Pain (NSCLBP) - A Randomized Controlled Trial

A randomized controlled trial of the efficacy of classification based cognitive functional physiotherapy according to the system proposed by Peter O'Sullivan as compared to manual therapy and exercise in patients with non specific chronic low back pain.

The investigators hypothesis was that treatment targeted at the mechanism behind the problem from a multidimensional perspective would be superior to traditional treatment.

NSCLBP is widely viewed as a multifactorial biopsychosocial pain syndrome. It has been proposed by several authors that NSCLBP represents a vicious cycle associated with different combinations of maladaptive; cognitive (negative beliefs, fear avoidance behaviours, catastrophising, depression, stress, lack of pacing and coping), physical (pain provocative postures, movement patterns and pain behaviours) and lifestyle (inactivity, rest) behaviours that act to promote pain and disability. However a recent systematic review suggests that this change in paradigm and our new understanding of NSCLBP has not resulted in clinical trials utilizing multidimensional classification systems or targeted interventions based on the underlying mechanisms. line with this shift in paradigm a novel multidimensional classification system has been developed incorporating the biopsychosocial model, which subgroups patients based on their presentation of. with matched interventions directed at the maladaptive cognitive, physical and lifestyle behaviours associated with the disorder.
