Prevalence of Sacroiliac Joint Dysfunction and Its Association with Low Back Pain Among Private Sector Female School Teachers

Background: Low back pain (LBP) is a common issue among school teachers due to prolonged standing and repetitive movements. Sacroiliac joint dysfunction (SIJD) is considered a potential contributor to LBP, but its role remains unclear.Objective: To determine the prevalence of SIJD and its association with LBP among female school teachers in the private sector.Methods: A cross-sectional study was conducted with 115 female school teachers aged 22-50 years from private schools in Lahore. Participants completed the Nordic Musculoskeletal Questionnaire (NMQ) and underwent five standardized provocative tests for SIJD: Distraction, Thigh Thrust, FABER, Compression, and Gaenslen’s tests. SIJD was defined as a positive result in at least three of these tests. Data were analyzed using chi-square tests and logistic regression in SPSS 25.Results: The prevalence of SIJD was 16.5% (n=19). LBP was reported by 38.3% (n=44) in the last 12 months and 47.8% (n=55) in the last 7 days. No significant association was found between SIJD and LBP (p=0.158 for 12 months; p=0.143 for 7 days).Conclusion: While SIJD was present in a subset of teachers, it was not significantly associated with LBP, suggesting other factors may contribute more to LBP.
