Aim: According to the results of the Kurjak antenatal neurodevelopmental test (KANET) in comparison of fetal behavior in single and twin pregnancies with the use of KANET test. Materials and methods: Between May 2015 and December 2019, 66 low-risk single pregnancies were assessed with KANET, along with eight twin pregnancies between 28 and 38 weeks of gestation. Results: Out of 66 patients with single pregnancies, 64.02 (97%) had a normal KANET score, and 1.8 (3%) of them had a borderline KANET score. Out of eight patients with twin pregnancies, 7.84 (98%) had a normal KANET score and 0.16 (2%) of them had a borderline KANET score. Conclusion: Our data suggest that twins show different types of motility than singletons at the same gestational age. The difference in the number of normal, borderline, and abnormal KANET scores between singletons and twins was not statistically significant, although the differences were found in certain parameters of the test between singletons and twins. It could be concluded that movements in twins become more complex and occur more frequently with increasing gestational age.
