Spine
Lumbo-Sacral Spine
Evidence: confirmed
Beevor Sign Special Test
Orthopedic Physical Examination & Clinical Assessment Guide
What is it used for?
- Diagnosing weakness of T10-T12 Nerve Roots or Spinal Cord Lesion.
How to Perform
- Position: Patient supine with knees bent.
- Action: Ask patient to lift their head and shoulders (partial sit-up).
- Observation: Watch the belly button (umbilicus).
Interpretation of Results
- Normal: Belly button stays in the center.
- Positive: Belly button moves upward, downward, or sideways.
- Interpretation: Movement indicates the muscles on the opposite side are weak (e.g., if it moves up, the lower abdominals are weak).
Clinical Context & Limitations
The Beevor Sign should be considered as one component of a comprehensive musculoskeletal assessment. No single special test has perfect diagnostic accuracy; thus, clinical decision-making should integrate test results with patient-reported symptoms, mechanism of injury, functional impairment, and relevant imaging.
Clinicians should be aware of potential false-positive results in patients with pain sensitisation, muscle guarding, or poor relaxation. For the Spine region, combining the Beevor Sign with complementary examination tests significantly improves overall diagnostic confidence.
