Question: 1 / 400

In measuring cervical spine flexion and extension, where should the axis of the goniometer be aligned?

Over the C7 vertebra

Over the scapula

Over the external auditory meatus

The axis of the goniometer should be aligned over the external auditory meatus for measuring cervical spine flexion and extension. This anatomical landmark is critical because it represents the center of rotation for the cervical spine during these movements. By positioning the goniometer in this way, the measurements will accurately reflect the true range of motion occurring at the cervical joints, facilitating consistent and reliable assessments.

Aligning to other landmarks, such as the C7 vertebra or the nose, would not provide an accurate representation of the cervical spine's movement. The C7 vertebra is more relevant for certain measurements involving the thoracic spine, while aligning over the nose might not capture the nuances of cervical motion accurately. Thus, using the external auditory meatus ensures the most precise measurement for cervical spine flexion and extension.
