Evaluation of the electromyographic activity of distal and proximal muscles of the lower extremity after ankle sprain (Review Article)

The purpose of this study was to investigate the effects of ankle sprain on the electromyographic activity of distal and proximal muscles of lower extremity. Data Source: A full literature electronic search was performed using google scholar, Science direct, Ovid database. The following keywords were used: Functional ankle sprain, Electromyography, Perturbation, Gluteus maximus, Gluteus medius, Tibialis anterior, Proneus longous. Study Selection: Study of Ankle sprain, English language articles, Case-Control studies and Use of surface electromyography. Data extraction: We found 29 articles through database (1995-2013) searching,13 articles, potentially relevant papers retrieved for evaluation of full text. Data Synthesis: Studies have found after ankle sprain, electromyography activity, onset time and amplitude of distal and proximal muscles of lower extremity decrease, postural control and movement pattern also changed. Key words: Electromyography, Functional ankle sprain & Gluteal muscles, Functional ankle sprain & peroneal muscles, Functional ankle sprain & perturbation.
