On the stork standing test, which finding would most strongly suggest a pars interarticularis stress injury?

• A. Bilateral sacroiliac pain
• B. No pain on either side
• C. Pain that worsens during hip extension
• D. Localized pain on the weight-bearing side during extension

Answer: (D)

The stork standing test targets stress on the pars interarticularis from lumbar extension under load. When you stand on one leg, you must balance while extending the spine, loading the pars interarticularis on the weight-bearing side. Localized pain in that region during extension most strongly points to a pars interarticularis stress injury, because it directly implicates the structure under repetitive extension stress. Bilateral sacroiliac pain suggests SI joint issues, no pain argues against injury, and pain only with hip extension is less specific to the pars area.
