Physiological motion of the lumbar spine is a subject of interest for musculoskeletal health care professionals, as abnormal motion is believed to be related to lumbar conditions and complaints. Many researchers have described ranges of motion for the lumbar spine, but only a few have mentioned specific motion patterns of each individual segment during flexion and extension. These motion patterns mostly comprise the sequence of segmental initiation in sagittal rotation. However, an adequate definition of physiological motion of the lumbar spine is still lacking. The reason for this is the reporting of different ranges of motion and sequences of segmental initiation in previous studies. Furthermore, due to insufficient fields of view, none of these papers have reported on maximum flexion and extension motion patterns of L1 to S1. In the lower cervical spine, a consistent pattern of segmental contributions was recently described. In order to understand physiological motion of the lumbar spine, it is necessary to systematically study motion patterns, including the sequence of segmental contribution, of vertebrae L1 to S1 in healthy individuals during maximum flexion and extension.
This study aims to define the lumbar spines' physiological motion pattern of vertebrae L1, L2, L3, L4, L5, and S1 by determining the sequence of segmental contribution and the sequence of segmental initiation of motion in sagittal rotation of each vertebra during maximum flexion and extension. The secondary endpoint will be exploring the possibility of analyzing the intervertebral horizontal and vertical translation of each vertebra during maximum flexion and extension.
Cinematographic recordings will be performed in 11 healthy male participants, aged 18-25 years, without a history of spine problems. Cinematographic flexion and extension recordings will be made at two time points with a minimum 2-week interval in between.
The study has been approved by the local institutional medical ethical committee (Medical Research Ethics Committee of Zuyderland and Zuyd University of applied sciences) on September 24, 2018. Inclusion of participants will be completed in 2020.
If successful, these physiological motion patterns can be compared with motion patterns of patients with lumbar conditions before or after surgery. Ultimately, researchers may be able to determine differences in biomechanics that can potentially be linked to physical complaints like low back pain.

腰椎的生理运动是肌肉骨骼保健专业人员感兴趣的课题，因为异常运动被认为与腰椎疾病和不适有关。许多研究人员描述了腰椎的运动范围，但只有少数人提到了每个节段在屈伸过程中的特定运动模式。这些运动模式主要包括矢状面旋转节段起始的顺序。然而，目前仍缺乏对腰椎生理运动的充分定义。原因在于以往研究中报告的运动范围和节段起始顺序各不相同。此外，由于视野不足，这些论文均未报告L1至S1的最大屈伸运动模式。在颈椎下段，最近描述了一种一致的节段贡献模式。为了了解腰椎的生理运动，有必要系统地研究健康个体在最大屈伸过程中L1至S1椎体的运动模式，包括节段贡献顺序和节段起始顺序。
本研究旨在通过确定每个椎体在最大屈伸过程中矢状面旋转的节段贡献顺序和节段起始顺序，来定义L1、L2、L3、L4、L5和S1椎体的腰椎生理运动模式。次要终点将是探索分析每个椎体在最大屈伸过程中椎间水平和垂直平移的可能性。
将对11名年龄在18 - 25岁、无脊柱问题病史的健康男性参与者进行电影摄影记录。电影摄影屈伸记录将在两个时间点进行，间隔至少2周。
该研究于2018年9月24日获得当地机构医学伦理委员会（祖德兰德医学研究伦理委员会和祖德应用科学大学）批准。参与者纳入工作将于2020年完成。
如果成功，这些生理运动模式可与腰椎疾病患者手术前后的运动模式进行比较。最终，研究人员或许能够确定可能与腰痛等身体不适相关的生物力学差异。
