What is the best method for evaluating the range of motion of the ankles?

The best method for evaluating the range of motion of the ankles is to observe the heels lowering and lifting. This movement allows for a direct assessment of the ankle's dorsiflexion and plantarflexion capabilities. By lifting the heels, a person engages the muscles involved in plantarflexion, while lowering the heels tests dorsiflexion. This dynamic movement captures functional range of motion as it reflects real-life activities, indicating how well the ankle can move through its full range under load and in a weight-bearing position.

Other methods, while useful in certain contexts, do not provide a comprehensive evaluation as effectively. Flexibility tests focus primarily on static flexibility rather than dynamic movements. Simple ankle rotations assess mobility, but again, they do not replicate the functional context of daily movements. Resistance testing is beneficial for strength assessments but does not directly measure the range of motion. Hence, the assessment of heel movements offers the most insight into the functional capabilities of the ankle.
