One lumbar extension training session per week is sufficient for strength gains and reductions in pain in patients with chronic low back pain ergonomics.

Unlabelled: Chronic low back pain (CLBP) is the leading cause of absenteeism from the workplace and research into exercise interventions to address this problem is required. This study investigated training frequency for participants with CLBP. Participants either trained once a week (1 × week, n = 31), or twice a week (2 × week, n = 20) or did not (control group, n = 21).

The effect of lumbar extension training with and without pelvic stabilization on lumbar strength and low back pain.

Introduction: A dynamometer employing a stabilization procedure (lumbar extension machine, MedX, Ocala, FL) is effective in improving strength and reducing symptoms of low back pain (LBP), and researchers have hypothesized that this effectiveness is due to the pelvic stabilization. However, effects of the dynamometer with and without pelvic stabilization on LBP have not been compared: This was the aim of the present study.

Methods: Forty-two chronic LBP patients were randomly assigned to a lumbar extension training with pelvic stabilization group (STAB; n=15), a lumbar extension without pelvic stabilization group (NO-STAB; n=15) and a control group (n=12).
