Abstract
Mechanical low back pain (MLBP) is resulting from mechanical stress of the surrounding soft tissues. Study design: A randomized controlled trial. Comparing the effect of core training exercises with lumbopelvic-hip complex strength training on the balance in MLBP patients. Methods: twenty -four patients with MLBP assigned equally into two groups, Group A (n = 12) and group B (n = 12), core training and stretching exercises were applied for group A, while lumbo-pelvic-hip complex strengthening and stretching exercises applied for group B, respectively. T- test and paired t- test were used for comparing between the outcome measurements; overall stability index (OSI), antero-posterior stability index (APSI), and antero-medial stability index (AMSI) were measured by a Biodex Balance System.patients after six weeks of core training and lumbo-pelvic-hip complex strengthening exercise have no significant differences between two groups regarding OSI, APSI, and AMSI before and after the training, but there were significant changes within group.Core training or lumbo-pelvic-hip complex strengthening exercises improve the balance in MLBP patients.
