The Transition from Acute to Subacute and Chronic Low Back Pain

LBP influences disability and quality of life more than RP. Disability is predicted by pain duration and quality of life is predicted by disability, but pain severity predicts neither one of them. Changes related to determinants of disability and quality of life, and to the prediction of chronic disability, appear 14 days after the onset of pain, supporting that cutoff point for considering a patient as being subacute.
