The current study will try to answer the following research question:
In adults with sacroiliac joint dysfunction, what is the effect of combination LD strengthening exercises with gluteal strengthening exercises compared with gluteal strengthening exercises alone on the primary outcomes of this study (pain intensity during pressure on posterior superior iliac spine \[PSIS\] and neuropathic pain severity) and the secondary outcomes (disability, pelvic inclination, pelvic torsion, sacral inclination, GMax and LD strength)?
Participants will be devided equally into two groups:
1. Group A (Control group): will receive a gluteal strengthening exercise program.
2. Group B (Intervention group): will receive the same gluteal strengthening exercise program as group A, in addition to the LD strengthening exercise program.
