Primary Outcome Measures

Name	Time	Method
The primary variable is the change in pelvic movement in the sagittal plane (pelvic tilt) while walking after spinal fusion surgery of the lumbar spine. This is tested before and six months after the operation through an instrumental gait analysis using the VICON infrared camera system and the AMTI force plate. The mobility of the upper body is quantified using light-reflecting markers and the infrared camera system. <br>We plan to include 30 patients in total. In particular, we aim to test whether fusion of the lumbar spine has a functional impact on typical everyday movements and / or gait as well as the sagittal profile of the total spinal column. Especially the analysis of the balance of the spine is of high clinical importance and scientific interest.<br><br>
