In the Thomas test interpretation, a greater lift of the extended leg indicates what?

• A. Less severe tightness.
• B. More severe hip flexor tightness.
• C. Rectus femoris tightness only.
• D. Iliopsoas laxity.

Answer: (B)

The Thomas test is used to assess the length and flexibility of the hip flexor muscles. When you pull one thigh toward the chest to flatten the lower back, the opposite leg should rest on the table. If that extended leg lifts off the table, it indicates the hip flexors are tight and pulling the leg upward. The bigger the lift, the more severe the hip flexor tightness, with the iliopsoas being the primary muscle involved. This pattern reflects tightness rather than laxity, and it’s not limited to the rectus femoris alone.
