Abstract

Repetitive sagittal trunk movements represent an occupational risk factor leading to cumulative trunk loading which can be associated with the development of low back pain (LBP) (Coenen et al., 2014). A possible mechanism causing an increased loading effect in LBP relates to impaired adaptation of speed control during goal-directed trunk movements (Zhou et al., 2016). This study explored trunk temporal coordination pattern during repetitive goal-directed sagittal trunk movements in LBP people compared to asymptomatic control.
