Ely test purpose?

Ely test purpose?

• A. To assess hamstring length
• B. To assess hip adductor length
• C. To assess gastrocnemius length
• D. To assess rectus femoris muscle length

Answer: (D)

Rectus femoris length is what the Ely test evaluates. This test leverages the fact that rectus femoris crosses both the hip and the knee. With you lying face down, the knee is flexed toward the buttock. If the rectus femoris is tight, shortening across the knee tends to pull the hip into flexion, so the thigh rises off the table or the pelvis tilts as the knee is bent. That hip movement indicates limited length of the rectus femoris. In contrast, tight hamstrings wouldn’t produce that hip flexion cue in this position, so the test helps distinguish rectus femoris tightness from other muscle-length issues. A normal result is when the knee can bend without the hip lifting, indicating adequate rectus femoris length.
