Patients with low back pain use stiffening strategy to compensate for movement control during active prone hip rotation: A cross-sectional study

New motor adaptation to pain theory suggests that patients with low back pain (LBP) use the lumbopelvic stiffening strategy by redistribution of within and between muscle activities to protect painful structure. This could result in an altered postural control of the lumbopelvic region during active prone hip rotation (PHR).
