“…Santilli et al 33 compared the latency of the peroneus longus during the stance phase of gait in the injured and the uninjured limbs as a short-term consequence of lateral ankle sprains in a population with functional ankle instability. They noted an immediate neuromuscular deficit between limbs within participants.…”

“…17 This has been supported by increased neuromuscular activity of the peroneus longus in individuals with CAI during the first 80 milliseconds after heel strike. 19 However, Santilli et al 33 identified a decrease in peroneal muscle activation in the injured limb compared with the uninjured limb. We believe that examining the neuromuscular control of the entire gait cycle and the activity of muscles acting on the ankle, knee, and hip may be beneficial.…”

Context: Ankle sprains are among the most common musculoskeletal injuries, and many individuals with ankle sprains develop chronic ankle instability (CAI). Individuals with CAI exhibit proprioceptive and postural-control deficits, as well as altered osteokinematics, during gait. Neuromuscular activity is theorized to play a pivotal role in CAI, but deficits during walking are unclear.Objective: To compare motor-recruitment patterns as demonstrated by surface electromyography amplitudes between participants with CAI and healthy control participants during walking.Design: Descriptive laboratory study. Setting: Laboratory.Patients or Other Participants: Fifteen adults with CAI (5 men, 10 women; age ¼ 23 6 4.2 years, height ¼ 173 6 10.8 cm, mass ¼ 72.4 6 14 kg) and 15 matched healthy control adults (5 men, 10 women; age ¼ 22.9 6 3.4 years, height ¼ 173 6 9.4 cm, mass ¼ 70.8 6 18 kg).Intervention(s): Participants walked shod on a treadmill while surface electromyography signals were recorded from the anterior tibialis, peroneus longus, lateral gastrocnemius, rectus femoris, biceps femoris, and gluteus medius muscles.Main Outcome Measure(s): Preinitial contact amplitude, postinitial contact amplitude, time of activation relative to initial contact, and percentage of activation time across the stride cycle were calculated for each muscle.Results: Time of activation for all muscles tested occurred earlier in the CAI group than in the control group. The peroneus longus was activated for a longer duration across the entire stride cycle in the CAI group (36.0% 6 10.3%) than the control group (23.3% 6 22.2%; P ¼ .05). No differences were noted between groups for measures of electromyographic amplitude at either preinitial or postinitial contact (P . .05).Conclusions: We identified differences between the CAI and control groups in the timing of muscle activation relative to heel strike in multiple lower extremity muscles and in the percentage of activation time across the entire stride cycle in the peroneus longus muscle. Individuals with CAI demonstrated neuromuscular-activation strategies throughout the lower extremity that were different from those of healthy control participants. Targeted therapeutic interventions for CAI may need to be focused on restoring normal neuromuscular function during gait.

“…De forma interessante, ambos os estudos sugerem que os déficits apresentados em ambos os testes estão relacionados com uma dificuldade dos sujeitos com instabilidade de tornozelo de realizarem as correções posturais necessárias para completar as tarefas motoras requeridas, ou seja, esses sujeitos apresentariam um déficit de equilíbrio dinâmico. Recentemente, uma série de estudos detectaram alterações da atividade muscular durante a execução de atividades funcionais, como o andar (24)(25)(26)(27) e durante a aterrissagem após a realização de saltos (28)(29)(30) . Assim, os déficits de performance funcional observados nos indivíduos que executaram os testes Multiple hop test e SEBT reforçam a ideia de que a instabilidade de tornozelo está relacionada com a presença de déficits proprioceptivos e de controle neuromuscular (13,31,32 (20) utilizaram o Multiple hop test em seu estudo e atestaram que, além de esse teste ser capaz de detectar déficits de performance funcional em indivíduos com instabilidade de tornozelo, ele é uma ferramenta válida e confiável.…”

INTRODUÇÃO E OBJETIVO: Os entorses do tornozelo estão entre as lesões mais frequentes nos esportes, nas atividades de vida diária, nos acidentes e nos departamentos de emergências médicas, afetando principalmente os indivíduos jovens fisicamente ativos. O objetivo deste trabalho foi realizar uma revisão sistemática da literatura a fim de levantar a existência de medidas clínicas que avaliem a performance funcional de indivíduos com instabilidade crônica do tornozelo, assim como a de estudos que verifiquem objetivamente a presença de déficits de performance funcional nesses indivíduos. MÉTODO: Foi conduzida uma busca nas bases de dados Medline, Embase e Lilacs. Essa revisão incluiu estudos que descrevem instrumentos de avaliação da performance funcional em indivíduos com instabilidade crônica do tornozelo. Os dois revisores realizaram buscas nas bases de dados computadorizadas de forma independente. RESULTADOS: No total, seis estudos foram incluídos, apenas três considerados de alta qualidade. Os testes descritos na literatura para avaliação de performance funcional em indivíduos com instabilidade do tornozelo foram Cocontraction test, Shuttle run test, Agility hop test, Triple-crossover hop for distance, 6-m shuttle run, Figure-of-8-hop, Side hop, Up-down-hop, Single hop, Multiple hop test e Star excursion balance test. Apenas os dois últimos testes foram capazes de detectar déficits de performance funcional em indivíduos com instabilidade de tornozelo. CONCLUSÃO: Observou-se que, até o momento, apenas os testes Multiple hop test e SEBT têm sua validade e confiabilidade atestadas como ferramentas capazes de detectar déficits de performance funcional em indivíduos com instabilidade do tornozelo.

“…A posteriorly positioned fibula predisposes a normal subject to ankle sprain injury (Eren et al, 2003). The delayed peroneus longus muscle activation time could cause lateral ankle sprains (Santilli et al, 2005). The information of identified aetiology further helps establishing the injury mechanism.…”
