What testing method evaluates the range of motion of the spine?

Goniometry is the correct choice as it specifically measures the range of motion in joints, including the spine. This technique involves the use of a goniometer, a tool designed to assess the angle of movement at various joints. In the context of the spine, practitioners use goniometry to evaluate flexion, extension, lateral bending, and rotation, providing valuable information about a patient’s functional capabilities and limitations.

Radiography, myelography, and magnetic resonance imaging are diagnostic imaging techniques primarily used to visualize structures within the body. While they can provide important information related to spinal health, such as detecting fractures, tumors, or disc herniation, they do not measure range of motion directly. Instead, these imaging methods are more focused on anatomical details rather than the functional aspects of movement assessed by goniometry.
