Which movement limitation is expected after damage to the gracilis muscle?

• A. Knee extension
• B. Ankle dorsiflexion
• C. Hip adduction
• D. Pelvic rotation

Answer: (C)

The gracilis muscle is one of the muscles located in the inner thigh, and it plays a significant role in hip adduction, which is the movement of bringing the thigh closer to the midline of the body. When there is damage to the gracilis muscle, the ability to perform this specific action is compromised, resulting in a limitation in hip adduction. In addition to assisting with adduction, the gracilis also aids in knee flexion and medial rotation. However, the primary function relevant to the question focuses on its role in hip adduction. The other movements listed, such as knee extension, ankle dorsiflexion, and pelvic rotation, are not primarily related to the function of the gracilis muscle. Knee extension is mainly performed by the quadriceps group, while ankle dorsiflexion involves muscles in the anterior compartment of the lower leg. Pelvic rotation is generally influenced by various muscle groups, including those in the hip and lower back regions, rather than specifically by the gracilis. Hence, the expected limitation after damage to the gracilis muscle is specifically in hip adduction.
