“The Effect of Lumbar Extension Training With and Without Pelvic Stabilization on Lumbar Strength and Low Back Pain”
Smith et al, Journal of Back and Musculoskeletal Rehabilitation, 24 (2011) 241-249/BMR-2011-0301
Strong Clinical Performance…Quantitatively better clinical outcomes. A just published randomized clinical trial (RCT) undertaken in the UK concludes that pelvic stabilization in the treatment of chronic low back pain, a foundation principle in the Dynamic protocol, results in significantly improved outcomes. (Study attached).
“Results: After the [controlled] exercise program, the STAB group [with pelvic stabilization] increased significantly in lumbar strength at all joint angles, and decreased significantly in visual analogue [pain] and Oswestry scores [disability related to low back pain]. However, there were no significant changes in these variables in the non-pelvic stabilized (NO-STAB) and control groups [conventional physical therapy].”
“Discussion: Isolated lumbar extension exercise is very effective in reducing LBP [low back pain] in chronic patients. When the pelvis is not stabilized, otherwise identical exercises appear ineffective in reducing LBP.”
“In conclusion, pelvic stabilization during lumbar extension exercise is essential to produce meaningful results. This is true both in terms of increasing the strength of the lumbar muscles and, more importantly from a clinical point of view, reducing the intensity of LBP [low back pain] and associated disability.

Note: Additionally, this randomized controlled trial complements and enhances related similar findings of some 70 prior clinical studies of specialized lumbar extension therapy in the treatment of low back pain.
Additionally, Dynamic asked Dr. Shlomo Sawilowsky, Professor of Educational Statistics and Distinguished Faculty Fellow at Wayne State University (WSU), to review this paper and to comment critically on the robustness of the study and its statistical validity.
In 2008 Dr. Sawilowsky served as president of the American Educational Research Association Special Interest Group/Educational Statisticians. He is Assistant Dean in the College of Education at WSU.
Dr. Sawilowsky concludes: “The study is of excellent quality, has all of the elements of the highest grade statistical analysis, with extremely high reliability test and retest capabilities stable over time. The study is impeccable.”
