SI  joint dysfunction is the putative source of  lower  back pain, many times presented with radicular symptoms and  miss-lead as the lumbar problem. Numerous medical researches have assessed the prevalence of sacroiliac joint dysfunction in the general population, which is between 19.3% and 47.9% among individuals with low back pain. Women are more likely to experience it.due to the load-bearing surfaces in the SI joint, the consequences of pregnancy, a sedentary lifestyle, or prolonged standing with the sacrum more horizontal.

Objective :The purpose of this study is to estimate the prevalence of sacroiliac joint dysfunction in the adult female population.

Methodology :A cross sectional study was conducted on 372 adult female participants taken from general population and divided into young adult (ages 18–35 years) and  middle-aged adult females (ages 36–55 years).Females who meet the inclusion and exclusion criteria where selected using non-probability sampling technique . Five pain provocation tests were used for evaluation: the SI distraction test, the SI compression test, the thigh thurst test, the Faber test, and the Gensler test. The assumption made was that the presence of discomfort in more than three tests implies involvement of the sacroiliac joint. The gathered information was filled out and examined.

Results :The study result showed that out of  372 adult females 100 (11.02%) were positive to sacroiliac joint pain. The dysfunction was more common in middle-aged adult females that were 18.4% out of 125 participants.

Conclusion: It was concluded that the prevalence of sacroiliac joint dysfunction among adult females is 11.02 % and it was significantly more common among middle aged adult females.
