Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Patients... - must have pain in the back or leg and require lumbar spine radiographs so the orthopaedic surgeon is able to diagnose the probable cause of the pain. - must be over 18 years of age - must be able to flex and extend the spine sufficiently to facilitate acceptable flexion and extension radiographs (based on the orthopaedic surgeon*s subjective assessment).

Exclusion criteria

Exclusion criteria: Patients will be excluded from participation if they... - have any form of spine-related traumatic injury - have had prior lumbar spinal surgery - have lateral spondylolisthesis or coronal plane curvature in the lumbar spine of >10° - duffer from involuntary back muscle spasms - have significant changes in back or leg pain during the day - are unable to understand and sign the study Informed Consent Form - are unable to follow oral instructions.

Design outcomes

Primary

MeasureTime frame
The main outcome of interest is the agreement between the participants* first (*test*) and second (*retest*) kinematic results using a validated measurement technology. The kinematic outcomes include intervertebral translation, intervertebral rotation and a value derived form the latter: translation-per-degree-of-rotation.
