Characterizing motor planning and feedback control strategies in individuals with recurrent low back pain

This study characterized trunk motor control strategies in subjects with low back pain (LBP) using a goal-directed, unstable sitting task assessing feedforward (motor planning) and feedback control of the lumbopelvic system. Center of pressure (COP)-based outcomes suggested that feedforward strategies were not different between subjects with and without LBP, yet differences in feedback strategy were observed.
