Low back pain : a comparative study on the value of core training versus traditional strengthening exercises

This randomised controlled trial (RCT) employed a pre-test/post-test design to compare the effects of core training (Pilates method) and traditional back exercises on a population with low back pain (LBP). Therapeutic intervention related to the Pilates method has recently become popular, but there is little evidence to prove it works. In this study, 120 individuals with LBP were allocated to three different groups. Group A was the control group, Group B was given modified Pilates intervention and Group C received traditional back exercises. All three groups were given a posture re-education session and back-care advice. After the initial session, the control group had individual sessions on posture re-education. The other groups undertook a six-week course of either modified Pilates or general back exercise classes. The modified Pilates group was taught how to use the core muscles, incorporating stabilisation with increasing functional movements. The back exercise group did similar exercises without learning to specifically stabilise. The Oswestry Low Back Pain Disability Questionnaire (ODQ) and the Visual Analogue Scale (VAS) were used as measures for pain and functional disability. Post-test ODQ readings showed no significant difference for pain-related function whilst VAS readings revealed a significant improvement in pain levels in all three groups, with the control group showing the best scores. However, the six-month follow-up scores showed that only the modified Pilates group continued to improve. At this stage, the control group was beginning to regress and the back exercise group was almost back to baseline measures. It was therefore concluded that core stability exercises have better long-term effects than traditional back exercisespeer-reviewe
