When standing on tiptoes, the tibialis anterior muscle is at full extension and is unable to "do" anything.
The tibialis anterior and tibialis posterior muscles are primarily assessed when the foot is placed in inversion. Tibialis anterior helps with dorsiflexion and inversion, while tibialis posterior assists with inversion and plantar flexion of the foot.
The anterior tibialis muscle is located in the front part of the lower leg. It runs along the shin bone (tibia) and is responsible for dorsiflexion of the foot, which means it helps lift the foot upwards towards the shin.
The prime mover in ankle dorsiflexion is the tibialis anterior muscle, which is located at the front of the shin. This muscle contracts to pull the foot upward, allowing for dorsiflexion of the ankle joint.
The prime movers for plantar flexion are the gastrocnemius and soleus muscles. The gastrocnemius is responsible for fast, powerful movements while the soleus provides endurance and stability during activities like walking and running.
The peroneal nerve, also known as the common fibular nerve, primarily serves the muscles in the anterior and lateral compartments of the leg. This includes the tibialis anterior, which is responsible for dorsiflexion of the foot, and the peroneus longus and peroneus brevis, which facilitate eversion of the foot. Additionally, it innervates the extensor muscles in the foot, aiding in toe extension.

The opposite muscle to the tibialis anterior is the gastrocnemius muscle, which is located at the back of the lower leg. The tibialis anterior is responsible for dorsiflexion of the foot (bringing the toes toward the shin), while the gastrocnemius is responsible for plantarflexion of the foot (pointing the toes away from the shin).

tibialis anterior muscle. It is located in the front of the lower leg and performs dorsiflexion of the foot, which is the opposite movement of the plantarflexion action of the gastrocnemius muscle.
