Association Between Chronic Ankle Instability and Sacroiliac Joint Dysfunction

chronic ankle instability previously approved in many studies that it may lead to more proximal adaptations and negative long term consequences. one of those studies reported, ankle instability patients has hamstring muscle shortening in comparison with non sprained subjects. another one concluded that gluteus maximums muscle has delayed activation and weakness in CAI patients. Both muscles (hamstring and gluteus Maximus ) contribute to sacroiliac joint stability. therefore, this study asked a novel research question, was sacroiliac joint dysfunction (SIJD) associated with CAI?
