The Cervical Flexion-Rotation Test (CFRT), in contrast to other forms of manual examination, is an easily applied clinical test purportedly biased to assess dysfunction at the C1-C2 motion segment. endstream endobj This small amount of motion is not surprising, given that maximal sagittal plane angular motion in the lumbar spine is very limited, with only 10° to 17° of total flexion plus extension motion at any segment.19 Our measurement of angular motion from the MRI during the limited amount of flexion and extension that could be achieved within the bore of the magnetic resonance device reflects even less angular motion (6°–9°). <>stream ��E%� ^��Ey�9 endstream measuring lumbar flexion and extension in Indian population. Based on the assumption that the vertebrae can be modeled as rigid bodies, the distance between the spinous processes increases as one flexes and decreases as one extends the lumbar spine, due to the angular rotation and the translational motion of each vertebra.

Accurate measurement of intervertebral kinematics of the cervical spine can support the diagnosis of widespread diseases related to neck pain, such as chronic whiplash dysfunction, arthritis, and segmental degeneration. This small amount of motion and the low number of subjects might also have contributed to the increased error. The first aim of the physiotherapy examination for a patient presenting with back pain is to classify the patient according to the diagnostic triage recommended in international back pain guidelines.
