The association of physical activity and sedentary behaviour with low back pain disability trajectories: A prospective cohort study.

Background: Multiple factors influence the recovery process of low back pain (LBP). The identification and increased knowledge of risk factors might contribute to a better understanding of the course of LBP.

Objectives: To investigate the association of habitual physical activity (PA) and sedentary behaviour (SB), measured at baseline, with disability trajectories in adults with LBP.

The association of the STarT Back Screening Tool and type of leg pain with low back pain disability trajectories: a prospective cohort study.

Background: Multiple factors influence the recovery process of low back pain (LBP). The identification and increased knowledge of prognostic factors might contribute to a better understanding of the course of LBP. The purpose of this study is to investigate the association of the STarT Back Screening Tool (SBST) risk score and the type of leg pain (non-radiating LBP, referred non-radicular, and radicular radiating leg pain) with the disability trajectory (at baseline, the slope, and recovery at one year) in adults with low back pain.
