Additional Gluteal Control Training for Low Back Pain With Functional Leg Length Inequality

Low back pain (LBP) is a prevalent musculoskeletal disorder. A variety of exercise interventions which were designed as randomized control trails (RCTs) have been studied and shown effectiveness in improving pain and disability. These exercises typically focus on the abdominal and back musculature strength. However, many LBP patients did not show any improvement in their symptom after they carry out those exercise programs.

About this study

Low back pain (LBP) is a prevalent musculoskeletal disorder. A variety of exercise interventions which were designed as randomized control trails (RCTs) have been studied and shown effectiveness in improving pain and disability. These exercises typically focus on the abdominal and back musculature strength. However, many LBP patients did not show any improvement in their symptom after they carry out those exercise programs. Some authors consider that this type of low back pain may be caused by leg length inequality (LLI) in these patients, which resulted from poor gluteal neuromuscular control or muscles' imbalance.

In consideration of few studies have been done for investigating the effects of gluteal muscles control training in LBP. Thus, the purpose of this study is to investigate the effect of additional gluteal muscles control training on improving functional LLI in patients with LBP. We hypothesized that gluteal muscle control training would be more effective in self-reported pain, and their functional disability would be improve after 6-week training program than control training group.
