Objectives

The pre-manipulative vertebrobasilar insufficiency tests (PVBIT) generally incorporate cervical rotation to verify the solvency of the vertebral arteries (VA). However, research on the effect of rotation on VA blood flow differ and question the validity of the tests. The first aim of this study was to verify the effect of cervical rotation on the hemodynamic parameters of the VAs in healthy subjects.

Material and method

Ten healthy female volunteers, aged 18 to 23 years (mean: 20.3, SD: 1.64 years), were subjected to bilateral Doppler ultrasonographies over the suboccipital segment of the AV (AV3) with neutral, contralateral and ipsilateral cervical rotation positions. We calculated peak systolic velocity (PSV), peak diastolic velocity (PDV), mean velocity (MV) and resistance index (RI). The data were analyzed with repeated measures ANOVA and comparisons were made with Bonferroni correction (SPSS v15.0, C.I. 95%).

Results

No statistically significant differences were detected regarding lateralization or rotation in the values of PSV (FPSV = 0.935, P=.47), or PDV (FPDV = 1.067, P=.39), or MV (FMV = 1.172, P=.34), or RI (FRI = 1.183, P=.33). The low power of analysis (between 30 and 38%) should be noted and thus the absence of differences should be observed with caution.

Conclusions

Hemodynamic parameters of the VA did not change with cervical rotations in healthy women so that this question should be studied in patients with vertebrobasilar insufficiency.
