BACKGROUND: Pelvic misalignments such as lateral pelvic tilt may lead to dysfunctions and pain complaints. Studies in the literature have indicated several factors associated with lateral pelvic tilt, and one of these is the length of the iliotibial band. OBJECTIVE: Investigate the presence of an association between iliotibial band length and frontal plane pelvic tilt. METHOD: Thirty-two asymptomatic individuals of both sexes (22.5 ± 2.6 years), without leg-length differences or pelvic torsion, were included in the study. The modified Ober test, performed with a pelvic level and an inclinometer, was used to assess the iliotibial band length. To determine the pelvic misalignment in the frontal plane, the individual was positioned on standard support equipment and pelvic structure measurements were obtained using an anthropometer. Pearson's correlation coefficient was utilized to determine the degree of association between pelvic misalignment in the frontal plane (established as the difference in height between higher and lower anterosuperior iliac spines) and the length of the iliotibial band (established as the difference in iliotibial band lengths corresponding to the higher and lower anterosuperior iliac spines). RESULTS: No statistically significant correlations were found between the variables analyzed (r=0.12; p=0.53). CONCLUSION: The present findings indicate that iliotibial band length alone does not appear to influence frontal plane pelvic alignment. Other factors may be involved and these still need to be identified.
