Abstract

<abstract abstract-type="executive-summary"> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title>Objectives</title> <p>The purpose of this study was to examine the effect of pelvic compression in female patients with sacroiliac joint pain on: 1. the electromyographic [EMG] activity of muscles stabilizing the pelvis and 2. active straight leg raising [ASLR] score and its duration.</p> </sec> <sec> <title>Methods</title> <p>Surface EMG recordings were taken from the rectus abdominus, external and internal oblique, erector spinae, gluteos maximus, adductor longus, and biceps femoris while patients performed ASLR in supine, with or without pelvis compression [50 Newton]. The ASLR score and duration were also recorded.</p> </sec> <sec> <title>Results</title> <p>Pelvic compression significantly reduced the EMG activity from six muscles. The EMG normalized root mean square values declined during pelvic compression by 11 to 55 percent compared with those without compression. Reduction in normalized root mean square values was significant [P ≤ 0.01] for internal and external oblique muscles, and substantial for adductor longus [P ≤ 0.06]. Patients reported significantly lower ASLR scores [P ≤ 0.05] with pelvic compression than without. The ASLR duration under the test conditions, however, varied insignificantly [P ≤ 0.76], regardless of the pelvic compression.</p> </sec> <sec> <title>Conclusion</title> <p>The results suggest that pelvic compression can improve both the motor control and stability of the pelvis, while reducing joint pain in women suffering from sacroiliac joint symptoms.</p> </sec> </abstract>
