Indications

Forestier’s Bowstring sign is a thoracic spine examination procedure that assesses for changes in range of motion of the spine. It is a test to determine paraspinal musculature contracture, ankylosing spondylitis and pain inhibited motion. 

Procedure

Patient should be awake and cooperative as the Forestier’s Bowstring Sign is assessed.

  1. Patient should standing while this test is being done.
  2. The patient bends from side to side.
  3. The examiner checks for spinal range of motion specifically unequal motion.
orthopaedic examination of spine

The patient bends from side to side while examiner checks for spinal range of motion specifically unequal motion.

Interpretation

Positive Forestier’s Bowstring Sign

There is a positive Forestier’s Bowstring Sign when there is observed unequal motion as the patient bends from side to side. This could indicate the presence of paraspinal musculature contracture, ankylosing spondylitis and pain inhibited motion.
