Checkpoint 1; 10 cm proximal to calcaneal insertion; checkpoint 2: 8 cm proximal to calcaneal insertion; checkpoint 3: 6 cm proximal to calcaneal insertion. Take the midline of Achilles tendon as the “0” point. CP: clinical position: the distance from the sural nerve located by body surface location point to the midpoint of Achilles tendon; AP: actual position: the distance from the sural nerve located by ultrasonography to the midpoint of Achilles tendon; WAT; width of Achilles tendon: the distance from the medial edge to the lateral edge of the Achilles tendon on each plane.
