The prognosis of chronic low back pain is determined by changes in pain and disability in the initial period

Heymans, M.W. (author), van Buuren, S. (author), Knol, D.L. (author), Anema, J.R. (author), van Mechelen, W. (author), de Vet, H.C.W. (author), TNO Kwaliteit van Leven (author)

Background context: The recovery of patients with chronic low back pain (LBP) is slow. Furthermore, it is recently proposed that chronic LBP needs a prognostic approach to determine who will develop clinically significant back pain. Therefore, it is imperative to identify prognostic factors that are mostly seen in chronic LBP patients at an...

The aim of the study was to determine whether men and woman with equal tasks perform these tasks in the same way. Video recordings of 37 male and 43 female workers in six task groups were observed, from which data regarding frequency and duration of exposure to awkward postures were derived. These data were also compared to self-reported...
