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). The LOAB-trained group
performed low intensity isometric contractions on their abdominals that had
minimal effect on their back musculature. The two groups reported daily pain logs
on a weekly basis on an interactive voice response telephone system for 1 year.
RESULTS: The HIBE-trained group experienced more pain days (p = 0.038) in the
minor and moderate categories and more episodes of acute LBP than the
LOAB-trained group. However, there was a trend of less pain in the severe,
intense and excruciating categories in the HIBE-trained group. CONCLUSIONS: The
results of this experiment did not provide evidence that short-term intense
training of the low back musculature provides protection against future episodes of LBP.
