What assessment is used to evaluate the range of motion of the ankle joint?

• A. Dorsiflexion and plantarflexion testing
• B. Rotational movement assessment
• C. Varus and valgus stress tests
• D. Knee flexion assessment

Answer: (A)

The assessment used to evaluate the range of motion of the ankle joint focuses specifically on dorsiflexion and plantarflexion testing. These movements are critical for understanding how well the ankle can move through its full range of motion. Dorsiflexion refers to the action of lifting the foot upwards towards the shin, while plantarflexion involves pointing the toes away from the body.

Measuring both dorsiflexion and plantarflexion provides essential information about the flexibility and functionality of the ankle joint, which is crucial for activities such as walking, running, and jumping. Accurately assessing these movements allows healthcare professionals to identify any limitations or dysfunctions that could affect mobility and overall lower extremity health.

The other options involve assessments that either pertain to different joints or evaluate different types of movement. For example, rotational movement assessment generally applies to joints like the hip or shoulder. Varus and valgus stress tests are used to assess stability and integrity of joints, particularly at the knees or elbows. Knee flexion assessment focuses on the knee joint rather than the ankle. Thus, for assessing the range of motion specifically at the ankle, dorsiflexion and plantarflexion are the relevant movements to evaluate.
