Conclusions For most clinical tests in LBP there is not consistent evidence for an association with outcome .

Pain response classification does not predict long-term outcome in patients with low back pain who are sick-listed.
STUDY DESIGN Prospect i ve cohort study nested in a r and omized clinical trial . OBJECTIVE To investigate the prognostic value of pain response classification at initial physiotherapy examination in patients with low back pain ( LBP ) who are sick-listed . BACKGROUND Recurrent and chronic LBP accounts for a substantial proportion of all absence from work . In predicting outcome in patients with LBP , psychosocial factors are thought to play an important role , while findings from clinical examination seem to be of more limited value . Mechanical evaluation , using repeated end range spinal movements that result in specific pain responses , has been shown to be of some value . METHODS The study included 351 patients sick-listed because of LBP with or without sciatica . Prior to clinical examination , the patients completed a comprehensive question naire including questions on pain , function , and psychosocial factors . The physiotherapy examination included a st and ardized mechanical evaluation . Patients were classified into 3 groups according to their pain response : central ization , peripheralization , or no response . Outcomes were obtained by national register data , medical records , and a postal question naire at 1 year . RESULTS At 1-year follow-up , 65 % of the patients had returned to work . All pain response groups showed significant and clinical ly important improvements in both pain and disability . No significant differences were found between pain response groups in any outcome measure . Results remained unchanged after adjustment for potential confounders . CONCLUSION The prognostic value of pain response classification seems limited in patients sick-listed from work because of LBP
