Dynamic training of the lumbar musculature to prevent recurrence of acute low back pain: a randomized controlled trial using a daily pain recall for 1 year.

Purpose: The purpose of this experiment was to quantify lumbar muscle endurance training for individuals with a recent episode of acute low back pain (LBP) (≥ moderate pain for ≥ 2 days) and to observe whether the training would reduce the rate and severity of recurrent LBP episodes.

Method: Twenty-six participants who were pain-free at the time of the study were randomly divided into a high intensity back endurance (HIBE)-trained or a low intensity abdominal (LOAB)-trained (control) group. The HIBE-trained group performed preloaded maximum isokinetic exertions of the back extensors (five sets of 10 repetitions, 3 days a week for 4 weeks, totaling 12 sessions).
