II. Indication: Evaluation of Lumbar Spine Range of Motion
III. Technique
- Patient stands erect with normal Posture
- Identify level of posterosuperior iliac spine
- Mark midline at 5 cm below iliac spine
- Mark midline at 10 cm above iliac spine
- Patient bends at waist to full forward flexion
- Measure distance between 2 lines (started 15 cm apart)
IV. Interpretation
- Normal: distance between 2 lines increases to >20 cm
- Abnormal: distance does not increase to >20 cm
- Suggests decreased Lumbar Spine range of motion
- May suggest Ankylosing Spondylitis
