Effect of Retro Walking in Patients With Sacroiliac Joint Dysfunction

The goal of this clinical trial is to investigate the effect of adding retro-walking (RW) to core stabilization exercises (CSE) on isokinetic peak torque of lower limb muscles, pain severity, and disability level in patients with sacroiliac joint dysfunction(SIJD).The main questions it aims to answer are: Will there be any effect for the combined application of RW training and CSE on isokinetic peak torques of, hip extensors and abductors, knee extensors, and ankle planter-flexors, pain severity, and disability level in patients with SIJD? Will there be any difference between the combined application of RW training and CSE and the solo application of CSE on isokinetic peak torques hip extensors and abductors, knee extensors, and ankle planter-flexors, pain severity, and disability level in patients with SIJD?
