  Tibialis anterior muscle - Wikipedia, the free encyclopedia
The tibialis anterior is a muscle that spans the length of the tibia.
It arises from the lateral condyle and upper half or two-thirds of the lateral surface of the body of the tibia; from the adjoining part of the interosseous membrane; from the deep surface of the fascia; and from the intermuscular septum between it and the Extensor digitorum longus.
The Tibiofascialis anterior, a small muscle from the lower part of the tibia to the transverse or cruciate crural ligaments or deep fascia.

 Tibialis Anterior Draft - Wikipedia, the free encyclopedia
The tibialis anterior muscle is the most medial muscle of the anterior compartment of the leg.
It functions to stabilise the ankle as the foot hits the ground during the contact phase of walking and acts later to pull the foot clear of the ground during the swing phase.
Essentially, the movements of tibialis anterior are dorsiflexion and inversion of the foot.

Tibialis anterior originates from the lateral condyle and proximal half to two thirds of the lateral surface of the tibial shaft, the adjacent anterior surface of the interosseous membrane, the deep surface of the fascia cruris, and the intermuscular septum between the tibialis anterior and the extensor digitorum longus.
Tibialis anterior is innervated by the deep peroneal nerve from L4 and L5 spinal nerves.
Tibialis anterior is supplied by the anterior tibial artery, anterior tibial recurrent artery, anterior medial malleolar artery, arteria dorsalis pedis, medial tarsal arteries, and medial malleolar and calcaneal branches of the posterior tibial artery.

Anterior shin splints are considered an overuse syndrome of the tibialis anterior muscle and tendon.

The tibialis anterior runs down the lateral side of your shinbone, crosses under a ligament at your ankle, goes across the top of your foot and into the arch, inserting on the tarsal bone in your arch.
Runners are especially prone to experiencing pain at both the origination along the shinbone because the muscle is actually pulling along the length of the bone; the top of the foot where it bends at the ankle; and the bottom of the foot because of the insertion of this muscle in the arch.

During reperfusion of the acutely ischemic tibialis anterior of rabbits, the deep peroneal nerve's conduction was impaired and the action potential was abolished [29].
The proportion of type I fibres of the ischemic tibialis anterior increased to 66.2% after reperfusion (Table 3), a number closer to that reported for normal subjects [8,13,22-24], whereas the proportion of type II fibres proportionally decreased (Table 3), eventhough these changes in proportions of fibre types were not statistically significant.

 Lower leg injuries - how to stay trouble free   (Site not responding. Last check: 2007-10-26)
Five important muscles were studied, including three calf muscles (the gastroenemius, soleus, and tibialis posterior), one shin muscle (the tibialis anterior), and a unique muscle---the peroneus brevis-which runs down the lateral side of the lower leg to the outside of the foot.
In fact, the most active lower leg muscle is actually the tibialis anterior, a strip of sinew which runs down the shin to the inside edge of the foot and pulls the foot inward and upward.
During running, the tibialis anterior contracts forcefully about twice as often as any of the other four muscles, so it is probably the muscle most prone to fatigue.

 Shin Splints
The pain associated with shin splints is usually of a soft tissue origin involving microtears of muscle tissue (tibialis posterior and/or tibialis anterior) and/or chronic avulsion of the periosteal-fascial junction.
c) local fatigue of tibialis anterior and posterior due to extra strain decreases their ability to act as “shock absorbers” during weight bearing consequently transferring the stress directly to the tibia (shin bone).
Training Surfaces: walking, running and jumping on hard surfaces places extra strain on the tibialis anterior and posterior and subsequently stress may be transferred to the tibia.

On testing its ability to invert the foot (its other function along with Tibialis Anterior), it was found to be weak, and with the foot flat on the floor the two muscles showed poor control in their ability to increase the medial foot arch.
Once able to dorsiflex the foot just by using Tibialis Anterior (with the other toe extensors relaxed), the exercises were progressed by using theraband to increase the load and speed, to improve muscle control.
This was progressed to weightbearing, with Tibialis Posterior control, to maintain the foot arch and thus avoid pronation on functional exercises such as stepping, lunging and squats.

 Glossary search - tibialis anterior.
This muscle is in the anterior compartment of the leg and arises from the upper part of the tibia and the interosseous membrane.
The muscle is a dorsiflexor (extensor) and invertor of the foot; when the foot is on the ground, tibialis anterior is probably more useful in helping to accommodate to uneven ground by adjusting the position of the leg.
It is interesting to note that its insertion in the foot is the same as peroneus longus, the major evertor of the foot.

Manual muscle testing of the tibialis anterior: trigger points would definitely be painful because of the tension placed on the muscle, while periostitis would probably not be painful, as it is not located in the tibialis anterior muscle (it might be painful because of tension on the origin of the TA on the anterior tibia.
Resisted plantarflexion with the knee flexed tests the soleus, while inversion tests the tibialis posterior; overuse of these muscles is often the cause of shin splints so resisted testing should reproduce the patient’s pain complaint.
Strong, painfree dorsiflexion clears the tibialis anterior, which needs to be cleared because it is located over the anterior shin.
