Reliability of an Objective Measurement to Assess Lumbar Spine Motion in Healthy Controls and in Low Back Pain Patients

Main of the study is to assess the reliability of a new objective tool to measure lumbar spine motion. The data will be collected from healthy subjects and subjects with frequent or daily low back pain in the last three months. In addition we compare the results of the motion measurements with disability and pain questionnaires such as the Roland Morris, Oswestry Disability Index and the Brief Pain Inventory.
