Radiculopathy shows nerve root involvement, so exam findings fall in a specific dermatomal and myotomal pattern with reflex changes. When a root is irritated or compressed, sensory loss or altered sensation occurs in the corresponding dermatome, weakness appears in the myotome supplied by that root, and reflexes associated with that root can be decreased or pathologic. This precise, distributional deficit is what distinguishes radiculopathy from other sources of pain.

Non-dermatomal pain without neuro signs points away from a root issue and toward musculoskeletal or referred pain. Pain that improves with rest and is non-persistent also suggests a non-neurological process. Symmetric weakness without sensory loss implies a non-radicular process, such as a central or systemic condition, rather than a single nerve root problem.
