Core stabilisation exercises reduce chronic low back pain in Air Force fighter pilots: a randomised controlled trial.

Abstract

Background: There is evidence that core stabilisation, strength and endurance training contribute to reduce low back pain in the general population. However, we are not aware of the effect of these exercises on fighter aviation pilots. Therefore, the present study aims to investigate the effects of an exercise protocol on chronic low back pain in Brazilian Air Force fighter pilots. Changes in neck pain, lumbar disability, range of motion, strength and resistance were also investigated.

Methods: Fourteen participants with chronic low back pain were randomised into two groups: stabilisation exercise group (SEG-n=7), exercise protocol twice a week for 12 weeks) and the regular exercise group (REG-n=7), which performed their own usual exercise routine. The evaluations were carried out before and after the training period. The primary outcome was the intensity of low back pain and the secondary outcomes were cervical pain, functional disability, range of motion, maximum isometric strength and trunk muscle resistance.

Results: The SEG had a significant reduction in low back pain compared with the REG (difference of 2.3 points, p=0.04) and a lower rate of cervical pain (difference of 2.5 points, p=0.01) at the end of the protocol. Maintenance of trunk muscle strength was also observed in the SEG over the period, while the REG presented a decrease in flexural strength to the right side (difference between groups: -3.7%, p=0.04). There were no differences in the rates of disability, range of motion or resistance to fatigue between groups.

Conclusions: The stabilisation exercise programme focused on the core muscles was successful in decreasing the fighter pilots' chronic lumbar pain. Pilots are normally active; however, our results indicate that specific trunk training programmes should be offered considering the work needs of these subjects.
