求翻译：结果只有髋内收肌力、躯干屈伸肌力及颈部侧屈肌力差异性显著，其余肌力差异性不明显，说明青少年脊柱周围肌力对称性相对较好；是什么意思？

Results only hip adduction muscle strength, trunk flexion and extension muscle strength and neck flexor muscle strength differences significant no obvious differences in the remaining muscle strength, muscle symmetry of young people around the spinal column is relatively good;

It is only Western Europe results in muscle strength, muscle torso stretches and neck muscle strength variability side leading significant muscle differentiation, and the rest is not obvious that the young spine surrounding muscle symmetry of relatively good quality.

Finally only then in the hip the adductor strength, the torso bend the extensor strength and the pate side flexor strength difference are remarkable, other myo- strength difference is not obvious, shows around the young people spinal column the myo- strength symmetry relative good;

Results only in the adductor muscles of the hip, flexors and extensors of trunk muscle strength and lateral flexion of the neck muscle strength difference significantly, the remaining difference of muscle strength is not obvious about adolescent spinal muscle symmetry around relatively well;
