Pelvic rotation angles of stroke patients in the sitting and standing positions

[Purpose] The aims of this study were to investigate the pelvic rotation angles of stroke patients in the sitting and standing positions, and the difference between those angles. [Subjects] Thirty-eight patients with hemiparesis participated in this study. [Methods] Subjects’ pelvic rotation angles in the sitting and standing positions were measured. Multiple regression analysis of the difference between the pelvic rotation angles in the sitting and standing positions was conducted. [Results] The pelvis was rotated backward in the sitting and standing positions and the angles were 1.1 ± 3.6°C and 3.8 ± 6.4°C, respectively. The pelvic rotation angle in the standing position was significantly larger than in the sitting position. The Brunnstrom recovery stage of the lower limbs and walking ability were independent predictors of the difference between the pelvic rotation angle in the sitting and standing positions. [Conclusion] The pelvic rotation angle was affected by the severity of paralysis and walking ability of the stroke patients with hemiparesis.
