The investigators aim to analyze the physiological segmental motion of the lumbar spine during flexion and extension cinematographic recordings of asymptomatic individuals.
In this study the investigators aim to define the lumbar spines' physiological motion by analyzing sequence of initiation of motion and sequence of maximum contribution in segmental translation and rotation of each vertebra L1, L2, L3, L4, L5 and S1 by using flexion and extension cinematographic recordings in asymptomatic male participants. Participants will undergo two cinematographic recordings with an interval of two weeks. Segmental translation and rotation of each segment will be plotted against total range of motion of the lumbar spine for each individual participant. With these graphs the investigators can analyze if there are specific physiological motion patterns during flexion and extension of the lumbar spine. In the future, the investigators hope to compare these physiological motion patterns to potential abnormal motion patterns in patients suffering from lumbar spinal pathology or after lumbar spine surgery to gain knowledge about complaints and, for example, adjacent level disease.
