Introduction: The evaluation of Q angle is a common clinical practice however standardization regarding the best way does not exist. Objective: Compare the value of the Q angle in different static positions and rotations of lower limbs. Methods: Evaluated 56 volunteers, 30 women and 26 men, in the supine andunder static weight-bearing positions with parallel feet and with outward foot rotation. For calculate Q angle used Computerized Biophotogrammetry. Results: Have significant difference between the static weight-bearing position with parallel feet and static weight-bearing with outward foot rotation in the left side for both the sexes (p=0.00) and between the supine position with outward foot rotation and static weight-bearing with parallel feet of the left side (p=0.03), in the feminine sex. Conclusion: it is concluded that there are no differences between different positions and postures to review the Q angle, however we stress the importance of checking the relaxation of the muscles of the lower limbs.
