Which assessment tools are commonly used to evaluate hamstring flexibility?

• A. Modified Thomas test and shoulder flexion test.
• B. Active knee extension test and groin flexibility test.
• C. Straight-leg raise tests (active and passive) and the sit-and-reach test.
• D. Quadriceps length test and hip abductor test.

Answer: (C)

When checking hamstring flexibility, the most direct tools are the straight-leg raise tests and the sit-and-reach test. The straight-leg raise evaluates how much the hip can flex with the knee kept straight, which tensions the hamstrings and reveals their length. There are two ways this is used: an active straight-leg raise, where the person lifts the leg themselves, shows functional control and active flexibility; and a passive straight-leg raise, where the examiner moves the leg, confirming the muscle-tendon length once the person relaxes. The sit-and-reach test has you sit with legs extended and reach forward, and the distance you can reach reflects hamstring length in the extended position, with some contribution from lower back and hip mobility. Taken together, these tools are practical, widely used, and directly relevant to hamstring length. Other assessments focus on different muscle groups or regions (like hip flexors, quadriceps, groin/adductors, or shoulder mobility), so they don’t isolate hamstring length as effectively.
