Uvod: Križobolja je jedan od najčešćih mišićnokoštanih problema i vodeći uzrok onesposobljenosti. Najčešći uzroci križobolje povezuju se s biomehaničkim i posturalnim čimbenicima, osobito s anteriornim nagibom zdjelice i mišićnom neravnotežom, a klinička relevantnost nagiba zdjelice kao čimbenika rizika za križobolju još uvijek nejasna.

Cilj: Procijeniti odnos nagiba zdjelice i križobolje.

Materijali i metode: U istraživanju je sudjelovalo 49 ispitanika s kroničnom križoboljom. Postura zdjelice procjenjivana je sustavom Global Postural System Lab Leonardo (GPS). Na SIAS i SIPS postavljeni su markeri, a ispitanici su fotografirani bosi u standardiziranom stojećem položaju iz četiri projekcije. Roland Morris upitnik je korišten za procjenu onesposobljenja, a VAS skala za procjenu intenziteta boli.

Rezultati: Nije prisutna značajna povezanost položaja zdjelice (lijevo/desno te anteriorno/posteriorno poravnanje) s trajanjem tegoba, intenzitetom boli ni stupnjem onesposobljenja. Također, nije prisutna statistički značajna razliku između muškog i ženskog spola. Prosječni nagib zdjelice iznosio je 15,9° lijevo i 16,9° desno, pri čemu su žene imale veće prosječne vrijednosti od muškaraca. Prosječna vrijednost nagiba zdjelice lijevo iznosio je 14,08° za muški spol, odnosno 16,73° za ženski spol, dok je prosječna vrijednost nagiba zdjelice desno iznosio 14,80° za muški spol te 17,89° za ženski spol.

Zaključak: Prosječne vrijednosti kuta nagiba zdjelice u ovom istraživanju ne razlikuju se od asimptomatske populacije te nije pronađena povezanost s intenzitetom boli, stupnjem onesposobljenja ni trajanjem bolova. Iako istraživanje daje dodatne spoznaje, potrebna su daljnja istraživanja s većim uzorkom i kontrolnom skupinom.

Introduction: Low back pain is one of the most common musculoskeletal disorders and a leading cause of disability. The most common causes of low back pain are associated with biomechanical and postural factors, particularly anterior pelvic tilt and muscle imbalance; however, the clinical relevance of pelvic tilt as a risk factor for low back pain remains unclear.

Aim: To assess the relationship between pelvic tilt and low back pain.

Materials and methods: The study included 49 participants with chronic low back pain. Pelvic posture was assessed using the Global Postural System Lab Leonardo (GPS). Markers were placed on the ASIS and PSIS, and participants were photographed barefoot in a standardized standing position from four projections. The Roland-Morris Questionnaire was used to assess disability, and the Visual Analog Scale (VAS) was used to assess pain intensity

Results: No significant association was found between pelvic position (left/right and anterior/posterior alignment) and duration of symptoms, pain intensity, or level of disability. Additionally, no statistically significant difference was observed between males and females. The mean pelvic tilt was 15.9° on the left and 16.9° on the right, with women showing higher mean values than men. The mean left pelvic tilt was 14.08° in males and 16.73° in females, while the mean right pelvic tilt was 14.80° in males and 17.89° in females.

Conclusion: The mean values of the pelvic tilt angle in this study do not differ from those of the asymptomatic population, and no association was found with pain intensity, level of disability, or duration of symptoms. Although the study provides additional insights, further research with a larger sample size and a control group is needed.

Key words: pelvic tilt angle, chronic low back pain, photographic assessment, posture
