In Kendall test interpretation, persistent hip flexion indicates which tightness?

• A. Rectus femoris tightness
• B. Hamstring tightness
• C. Iliopsoas tightness
• D. Tensor fasciae latae tightness

Answer: (C)

The Kendall test is used to assess hip flexor length, especially the iliopsoas. In this setup, the leg to be tested is positioned so the hip is flexed while the knee is moved or supported in a way that allows the thigh to lower toward the table. If the hip remains in flexion (the thigh does not flatten fully on the table) despite the test being set up to allow extension, that persistent hip flexion points to tightness of the iliopsoas. The iliopsoas is the primary hip flexor, and when it’s short, it resists the hip’s extension during the test, causing the hip to stay flexed. Tightness in the rectus femoris, hamstrings, or tensor fasciae latae can affect movement in other ways, but the clear sign in this test pattern is iliopsoas tightness.
