7.4 ± 10.4 (-20 ÷ 32.5) |
NS |
| Mid-point of rotation for left hip |
8.1 ± 9.6 (-15 ÷ 38) |

| Static rotational offset of the pelvis |
7.0 ± 5.1 (0 ÷ 25) |
5.0 ± 4.3 (0 ÷ 17.5) |
0.0092 |

The means and standard deviations are given, followed by minimum and maximum in the brackets. IR – internal rotation, ER – external rotation. There is more important asymmetry in the range of hip rotation in girls with scoliosis than in controls, and in the severity of the static rotational offset of the pelvis. | |||
