The case group contains patients who had sacroiliac joint dysfunction based on physical examination, and the control group was patients with similar characteristics who attended for reasons other than spinal or lower limb problems. A fixed sports medicine specialist assessed both groups&#39; tenderness and tightness of adductor muscles.<br> <strong>Results. </strong>The level of tenderness (Kendall Tau correlation coefficient equal to 0.440 and P<0.001) and tightness (Kendall Tow correlation coefficient equal to 0.479 and P <0.001) of the hip adductor muscles in the case group were significantly higher. More people in the case group reported hip adductor muscle pain than the control group (P <0.001).<br> <strong>Conclusion. </strong>This study showed more hip adductor muscle involvement in people suffering from sacroiliac joint dysfunction.</div> Sacroiliac Joint Dysfunction, Hip Adductors, Low Back Pain, Muscle, Tightness 0 0 http://aassjournal.com/browse.php?a_code=A-11-1801-1&slc_lang=en&sid=1 Mohammad Hassabi hassabi@sbmu.ac.ir 100319475328460011290 100319475328460011290 No Department of Sports and Exercise Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran Amir Hosein Abedi Yekta Abedi_yekta@yahoo.com 100319475328460011291 100319475328460011291 No School of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran Shahin Salehi salehi2955@yahoo.com 100319475328460011292 100319475328460011292 No Department of Sports and Exercise Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran Mehrshad Poursaeid Esfahani mpoorsaid@yahoo.com 100319475328460011293 100319475328460011293 No Department of Sports and Exercise Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran Seyedeh Sara Shams sarashams6990@gmail.com 100319475328460011294 100319475328460011294 Yes School of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran Mohammad-reza Sohrabi m.sohrabi@sbmu.ac.ir 100319475328460011295 100319475328460011295 No Department of Community Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran
