II. Indication: Evaluation of Lumbar Spine Range of Motion

III. Technique

  1. Patient stands erect with normal Posture
  2. Identify level of posterosuperior iliac spine
    1. Mark midline at 5 cm below iliac spine
    2. Mark midline at 10 cm above iliac spine
  3. Patient bends at waist to full forward flexion
  4. Measure distance between 2 lines (started 15 cm apart)

IV. Interpretation

  1. Normal: distance between 2 lines increases to >20 cm
  2. Abnormal: distance does not increase to >20 cm
    1. Suggests decreased Lumbar Spine range of motion
    2. May suggest Ankylosing Spondylitis
