Spinal and pelvis motion has been studied by a variety of different methods, the majority of which have a number of limitations. The present study investigated motion characteristics of the lumbar spine and pelvis using a three-dimensional optoelectronic system. The aim of our study was to determine kinematic parameters of spine and pelvis during trunk flexion, extension and lateral bending in normal, healthy subjects. Kinematic motion analysis was performed on 63 asymptomatic volunteers for four different trunk motions. This study has shown that the pelvis range of motion is affected by the gender Contribution of pelvic movement to trunk flexion was 50%, while pelvic angle was significantly higher in women. During lateral bending female subjects had statistically significant higher values of vertebral arc with respect to male subjects. During extension the contribution of pelvic movement was 45%. There was no significant difference found in total angle, pelvic angle and vertebral arc.
脊柱和骨盆运动已通过多种不同方法进行了研究，其中大多数方法都有一些局限性。本研究使用三维光电系统研究了腰椎和骨盆的运动特征。我们研究的目的是确定正常健康受试者在躯干前屈、后伸和侧屈过程中脊柱和骨盆的运动学参数。对63名无症状志愿者进行了四种不同躯干运动的运动学分析。这项研究表明，骨盆的运动范围受性别影响。骨盆运动对躯干前屈的贡献为50%，而女性的骨盆角度明显更高。在侧屈过程中，女性受试者的椎弓角度相对于男性受试者在统计学上有显著更高的值。在后伸过程中，骨盆运动的贡献为45%。在总角度、骨盆角度和椎弓方面未发现显著差异。
