Relação da função dos músculos do complexo tornozelo-pé com a pronação-supinação da articulação subtalar em cadeia cinemática fechada: uma revisão de literatura

Abstract

Alterations of pronation-supination motion and posture of the foot-ankle complex (TCC) during closed chain activities such as walking, running and standing posture are often linked to an increased risk of lower limb injuries. Factors that could influence distal pronation-supination TCC, besides the anatomical misalignment with tibial varus, varus of the rearfoot and forefoot varus of, is the function of the muscles of the TCC. Strength and endurance of intrinsic and extrinsic muscles of the foot could affect the movements of pronation-supination at the subtalar joint in closed kinematic chain. However, there is still no consensus on the existence of an influence on the movement of these muscles and posture pronation-supination. Thus, the present study aims to conduct a literature review seeking a relationship between the function of the muscles of TCC with pronation-supination of this joint complex. We performed a literature search in Medline / PubMed, SciELO, Lilacs, Cochrane and Google Scholar and was selected 8 studies. Of the total of 8 studies, 4 found an association between fatigue of the muscles of TCC with increased subtalar pronation closed chain, one study observed increased pronation after inhibition of the posterior tibial nerve (lidocaine 1%), 1 study related strength gain muscle in TCC with decreased pronation, 1 study found no difference between the peak torque of the muscles of the foot inverters and eversors among people with plantar arch and normal plane, and one study found increased activity of the tibialis anterior muscle during the initial contact and posterior tibial thrust gait in people with plantar arch plan. The results suggest that the function of the muscles of TCC can be a factor resulting from the kinematics of the causal or TCC. Thus, functions of the muscles of TCC as strength, endurance and activation should be evaluated and considered in clinical approaches to prevention and treatment of diseases related to changes in pronation-supination movements of the TCC.
