Low back pain (LBP) is deﬁned as pain localised between the12th rib and the inferior gluteal folds, with or without leg pain. Most cases are non-speciﬁc, but in about 10% of cases a speciﬁc cause is identiﬁed. Red ﬂags are typical signs or symptoms that are frequently associated with speciﬁc LBP. Yellow ﬂags are prognostic factors associated with a more unfavourable and often chronic disabling course of the disease. LBP has a lifetime prevalence of 60e85%.At any one time, about 15% of adults have LBP. LBP poses an economic burden to society, mainly in terms of the large number of work days lost (indirect costs) and less so by direct treatment costs. A substantial proportion of individuals with chronic LBP has been found to have chronic widespread pain. LBP is often associated with other pain manifestations such as headache, abdominal pain and painin different locations of the extremities. Widespread pain is associated with a worse prognosis compared to localised LBP. Treatment targets are reduction of pain and better activity/participation, including prevention of disability as well as maintainance of work capacity. The evidence from selected and appraised guidelines, systematic reviews and major clinical studies was classiﬁed into fourlevels, level Ia being the best level with evidence from meta-analysis of randomised controlled trials. Key recommendations (level Ia): ﬁtness programmes and advice to stay active can reduce pain, improve function and can prevent LBP becoming chronic. Simple analgesics, NSAIDs and muscle relaxants can reduce pain and can improve and maintain function. Maintaining physical activity, avoiding rest andmanual therapy can reduce pain and maintain and restore function in acute LBP. Behavioural treatment can prevent LBP becoming chronic.

INTRODUCTION Low back pain (LBP) is deﬁned as pain localised between the 12th rib and the inferior gluteal folds, with or without leg pain. Most cases are non-speciﬁc, but in 5e10% of cases a speciﬁc cause is identiﬁed.Speciﬁc causes of back pain are some degenerative conditions, inﬂammatory conditions, infective and neoplastic causes, metabolic bone disease, referred pain, psychogenic pain, trauma and congenital disorders. Non-speciﬁc LBP is deﬁned as back pain with no known underlying pathology. The term ‘speciﬁc low back pain’ is restricted by some health care professionals to destructive diseases such as tumourand infection, as well as to diseases associated with a neurological deﬁcit, such as disc herniation and spinal stenosis. Others use this term in the presence of a localised source of pain when a speciﬁc structure of the spine is painful and if a speciﬁc diagnosis is available to characterise the cause of the pain. Acute LBP occurs suddenly after a period of a minimum of 6 months without LBP...
