An association between postural stability and sacroiliac joint pain - A case control study

Purpose: To evaluate and to find an association between postural stability amongst the subjects with sacroiliac iliac joint pain (SIJP) and compare it with healthy subjects. Methods: Single leg standing balance test with eyes closed (SLSBT-EC) was performed in 30 SIJP subjects without any visual, vestibular or other neuromusculoskeletal conditions and in 46 healthy controls aged 18-59 years. SLSBT-EC holding duration was measured for both the groups. "t"-test was done to compare the SLSBT (EC) holding duration between the groups and Fisher's exact test to find an association between postural stability and SIJP group. Results: SLSBT (EC) duration was significantly decreased (95% CI: t = 10.34, p = < 0.001) amongst the cases (15.56 s ± 4.73 s) as compared to healthy participants (26.06 s ± 4.05 s) and Fisher's exact test value for association between postural stability and SIJP was found to be statistically significant (F = 0.54, p = < 0.001). Conclusion: Subjects with SIJP exhibited diminished SLSBT (EC) holding duration compared to healthy controls suggesting proprioceptive deficits.
