The tibialis anterior is a muscle located in the front part of the lower leg. It plays a crucial role in foot movement, particularly in lifting the foot and controlling its position during walking and running. This muscle helps to dorsiflex the foot, which means it pulls the toes upward towards the shin. In addition to its primary function, the tibialis anterior also supports the arch of the foot and contributes to balance. Strengthening this muscle can improve overall lower leg function and reduce the risk of injuries, especially for athletes and active individuals.
