The tibialis anterior muscle, also known as the tibialis anticus, is the largest of four muscles in the anterior compartment of the leg. Its thick muscle belly arises from its proximal attachment at the lateral tibia; the tibialis anterior tendon (TAT) inserts distally on the medial border of the foot. The muscle is primarily responsible for dorsiflexion and inversion of the foot.[1][2]

Author: Kevin B. Rosenbloom, C.Ped, Sports Biomechanist The ankle joint is one of the most valuable structures in the human body because of its intricate articulating surfaces and function in ambulation. Dorsiflexion is another essential movement of the ankle joint worth discussing. The following is a summary that explores the range of motion, concise descriptions of the muscles contribution to the movement and briefly explores the interesting research into the muscles involved with dorsiflexion.

Tibialis anterior (TA) muscle is the largest dorsiflexor of the ankle joint and plays an important role during gait movement. However, descriptions of the TA attachment site are inconsistent even among major anatomy textbooks, and its origin, especially the attachment site for the tibia, has not been reported in detail. This study is the first experimental attempt to investigate the origin of the TA in detail, paying particular attention to the relationship with the shape of the tibia, including sex differences. Forty legs (20 males, 20 females) from twenty Japanese cadavers were examined. Gross anatomical examination of the TA's attachment site to the tibia and the tibia's shape was performed. The location of the distal end of the TA's attachment on tibia was significantly more distal in males than in females (p < 0.01). The anterior border of the tibia had a gentle S-like curve, with a medially convex curve in the proximal region and a laterally convex curve in the distal region in frontal plane. The most protruding point of the distal curve of the anterior border located significantly more proximal in females than in males (p = 0.02). There were sex differences in the distal end of the attachment site on tibia of the TA and the shape of the tibia. Consequently, the variations in the attachment site of TA were considered to provide for differences in function of TA. In males, the TA may enable advantageous power exertion, whereas in females it may work efficiently for dorsiflexion of ankle, respectively. Sex differences in TA's attachment site and the shape of the tibia may be involved in gait movement as well as frequency of lower leg disorders such as chronic exertional compartment syndrome.
12. Ankle and Foot Spasticity Patterns in Chronic Stroke Survivors ... - MDPI
As shown in Figure 1, the tibialis anterior muscle causes the ankle dorsiflexion and inversion, while the tibialis posterior muscle causes ankle plantarflexion ...
Chronic stroke survivors with spastic hemiplegia have various clinical presentations of ankle and foot muscle spasticity patterns. They are mechanical consequences of interactions between spasticity and weakness of surrounding muscles during walking. Four common ankle and foot spasticity patterns are described and discussed through sample cases. The patterns discussed are equinus, varus, equinovarus, and striatal toe deformities. Spasticity of the primary muscle(s) for each deformity is identified. However, it is emphasized that clinical presentation depends on the severity of spasticity and weakness of these muscles and their interactions. Careful and thorough clinical assessment of the ankle and foot deformities is needed to determine the primary cause of each deformity. An understanding of common ankle and foot spasticity patterns can help guide clinical assessment and selection of target spastic muscles for botulinum toxin injection or nerve block.
13. Tendinopathies of the Foot and Ankle - AAFP
Nov 15, 2009 · The posterior tibial tendon is a dynamic arch stabilizer; injury to this tendon can cause a painful flat-footed deformity with hindfoot valgus ...
Because our understanding of tendinopathy has evolved in recent years, the condition is now considered a degenerative process; this affects the approach to treatment. Initial therapy should always involve relative rest and modification of physical activity, use of rehabilitative exercises, and evaluation of intrinsic and extrinsic causes of injury. The posterior tibial tendon is a dynamic arch stabilizer; injury to this tendon can cause a painful flat-footed deformity with hindfoot valgus and midfoot abduction (characterized by the too many toes sign). Treatment of posterior tibial tendinopathy is determined by its severity and can include immobilization, orthotics, physical therapy, or subspecialty referral. Because peroneal tendinopathy is often misdiagnosed, it can lead to chronic lateral ankle pain and instability and should be suspected in a patient with either of these symptoms. Treatment involves physical therapy and close monitoring for surgical indications. Achilles tendinopathy is often caused by overtraining, use of inappropriate training surfaces, and poor flexibility. It is characterized by pain in the Achilles tendon 4 to 6 cm above the point of insertion into the calcaneus. Evidence from clinical trials shows that eccentric strengthening of the calf muscle can help patients with Achilles tendinopathy. Flexor hallucis longus tendinopathy is most common among ballet dancers. Patients may complain of an insidious onset of pain in the posteromedial aspect of the ankle; treatment involves correcting physical training errors, focusing on body mechanics, and strengthening the body's core. Anterior tibial tendinopathy is rare, but is typically seen in patients older than 45 years. It causes weakness in dorsiflexion of the ankle; treatment involves short-term immobilization and physical therapy.
