Avaliação da instabilidade crônica de tornozelo em atletas de voleibol através de testes funcionais

Abstract

INTRODUCTION: Volleyball is one of the most popular sports in the world, and the International Volleyball Federation represents about 150 million players in approximately 170 countries. Of all volleyball injuries, the ankle sprain is the most common acute injury and anterior knee pain stand out as the most common chronic injury. In 60% of cases, ankle sprain occurs in the end of the jump, at the moment ground contact, and it occurs in a shock on the foot of another athlete with a inversion movement (lateral ankle sprain). In order to reduce this high rate of ankle sprain, a preventive intervetion has been done. Among the methods of prevention, there are also tests that could help sports physical therapist to indentify future injuries in athletes that have never had this incident or identify chronic ankles’ instability in athletes with recurrent ankle sprain. OBJECTIVES: The objective of this study was identifying the ability of tests to predict the ankle sprain or identify the ankle chronic instability by a literature review. METHODS: Searches have been done on computerized databases of Pubmed, Medline, PEDro, Lilacs, Scielo and Bireme. The search was based on a combination of key words “ankle sprain”, “functional tests”, “prevention”, “injuries in sports”, “injuries in volleyball”, in Portuguese and English languages, from 1990 to 2011. CONCLUSION: Only the Multiple-Hop Test and Star Excursion Balance Test (SEBT) had its validity and reliability tested and theses tests were able tools to identify performance deficits in athletes with chronic ankle instability.
