Introduction: If increased laxity of ligaments during pregnancy is not compensated with changed neuro-motor control, this may lead to pelvic girdle pain, which we can assess with Colour Visual Analogue Scale (CVAS) and Active Straight Leg Raise (ASLR) test. Methods: Sixty expectant mothers were included who were twelve or more weeks pregnant. The pelvic girdle pain was assessed with the mentioned two tests. Each assessment was repeated twice. Results: Pearson’s correlation coefficient showed good correlation between the CVAS and ASLR test in the first (r = 0.755) as well as the second measurement (r = 0.808). The difference between the first and the second measurement with CVAS were significant (p = 0.03), while there were no significant differences between the first and the second measurement with the ASLR test. ASLR test also showed high repeatability (ICC=0.96). Conclusions: The ASLR test is valid, reliable and sensitive enough and presents a strong competition to all other clinical tests for the pelvic girdle pain assessment in pregnant women.
