Athletic Training Practice Exam

Which of the following would most likely be assessed if a patient has a tight hip flexor?

1. Knee extension

2. Hip extension

3. Ankle dorsiflexion

4. Hip flexion

The correct answer is: Hip flexion

When assessing a tight hip flexor, the focus is primarily on the function of the hip itself, particularly its ability to extend properly. Tight hip flexors can lead to restrictions in hip extension, as the muscles involved—such as the iliopsoas—are already in a shortened position. This can result in difficulty achieving a full range of motion when attempting to extend the hip. Assessing hip flexion might seem relevant, but it is the flexibility or tightness of the hip flexors that directly affects the hip's ability to extend rather than flex. Therefore, when someone has tight hip flexors, the hip extension assessment is more appropriate since it provides insight into the functional implications of the tightness. This assessment helps to determine whether the tightness is affecting overall mobility and biomechanics during activities.
