Prevention and Treatment of Ankle Sprain in Athletes

Abstract

Introduction: The ankle sprain is one of the most common injuries in athletes. Direct evaluation of the ligament laxity can be obtained through the objective measurement of extreme passive inversion and eversion movements, but there are few studies on the use of the evaluation of the passive re-sistive torque of the ankle to assess the capsule and ligaments resistance. Objective: The aim of this study was to compare the inversion and eversion passive torque in athletes with and without ankle sprains history. Method: 32 female basketball and volleyball athletes (16.06 ± 0.8 years old; 67.63 ± 8.17 kg; 177.8 ± 6.47 cm) participated in this study. Their ankles were divided into two groups: control group (29), composed of symptom-free ankles, and ankle sprain group, composed of ankles which have suffered injury (29). The resistive torque at maximum passive ankle movement was measured by the isokinetic dynamometer and the muscular activity by electromyography system. The athletes performed 2 repetitions of inversion and eversion movement at 5, 10 and 20°/s and the same protocol only at maximum inversion movement. Results: The resistive passive torque during the inversion and eversion was lower in the ankle sprain group. This group also showed lower torques at the maximum inversion movement. No differences were observed between inversion and eversion movement. Conclusions: Ankle sprain leads to lower passive torque, indicating reduction of the resistance of the lateral ankle ligaments and mechanical laxity.

The Impact of Chiropractic Manipulative Therapy on Chronic Recurrent Lateral Ankle Sprain Syndrome in Two Young Athletes

“…1,4 While treatment options focus more on managing the aftermath of the injury, the prevention of LAS also has clinical value. 13,14 Following LAS, ligament injury may result in laxity, 4,12,15 with mechanical instability being a possible consequence. 16 The lateral ankle ligament complex is the most affected, with the anterior talofibular ligament (ATFL) being the most frequently damaged.…”

Avaliação dinamométrica e eletromiográfica do efeito das bandagens funcionais na articulação do tornozelo

“…Cerca de 20 a 80% dos sujeitos que apresentam história de vários entorses em um curto período de tempo são mais susceptíveis a desenvolverem instabilidade crônica de tornozelo (Hertel, 2000;Denegar e Miller, 2002;Osborne et al, 2003;Hertel et al, 2006;Nakasa et al, 2008). Kitaoka et al (1994), seguindo as recomendações da American Orthopaedic Foot and Ankle Society (AOFAS), criaram um critério clínico para avaliação de incapacidade do tornozelo e retropé por meio de uma escala denominada AOFAS ankle-hindfoot scale.…”

“…Devido à alta incidência e ao custo gerado por entorse, muitos estudos são realizados para investigar as causas e diminuir a freqüência destas lesões (Osborne et al, 2003).…”

“…Apesar de extensas pesquisas clínicas e experimentais sobre o mecanismo dos entorses, a freqüência da lesão é alta (Osborne et al, 2003) e as razões pelas quais o entorse ocorre permanecem sem esclarecimentos, o que dificulta o sucesso da reabilitação.…”
