Abstract
[Purpose] This study aimed to identify correlations among pelvic positions and
differences in lower extremity joint angles during walking in female university students.
[Subjects] Thirty female university students were enrolled and their pelvic positions and
differences in lower extremity joint angles were measured. [Methods] Pelvic position,
pelvic torsion, and pelvic rotation were assessed using the BackMapper. In addition,
motion analysis was performed to derive differences between left and right flexion,
abduction, and external rotation ranges of hip joints; flexion, abduction, and external
rotation ranges of knee joints; and dorsiflexion, inversion, and abduction ranges of ankle
joints, according to X, Y, and Z-axes. [Results] Pelvic position was found to be
positively correlated with differences between left and right hip flexion (r=0.51), hip
abduction (r=0.62), knee flexion (r=0.45), knee abduction (r=0.42), and ankle inversion
(r=0.38). In addition, the difference between left and right hip abduction showed a
positive correlation with difference between left and right ankle dorsiflexion (r=0.64).
Moreover, differences between left and right knee flexion exhibited positive correlations
with differences between left and right knee abduction (r=0.41) and ankle inversion
(r=0.45). [Conclusion] Bilateral pelvic tilt angles are important as they lead to
bilateral differences in lower extremity joint angles during walking.
