“…When correlating the presence of pain with the incidence of dynamic valgus, there was no statistically significant difference between these variables, corroborating the already performed study 20 that aimed to verify the relationship between the q-angle with pain intensity and functional capacity, not finding any relationship between knee valgus and these variables. The results were similar to those found in the literature 21 when verifying if the increase of the q-angle would lead to increased knee pain.…”

RESUMO A avaliação do movimento é importante e necessária para identificar os riscos de lesão possibilitando a elaboração de programas de exercícios preventivos e corretivos, visando a melhora do desempenho das atividades funcionais e o consequente bem-estar. O objetivo deste estudo foi analisar e comparar a incidência do valgo dinâmico do joelho em mulheres praticantes de musculação e mulheres sedentárias, e identificar os sintomas álgicos e o potencial de lesão associados a essa alteração biomecânica. Sessenta mulheres foram divididas em dois grupos: praticantes de musculação e sedentárias, com idade entre 18 e 30 anos. Os dados foram coletados utilizando-se o sistema Functional Movement Screen e foram submetidos a análises estatísticas descritiva e inferencial. O valgo dinâmico do joelho é apresentado por 60% das mulheres sedentárias, quando comparadas às mulheres praticantes de musculação (33,3%), demonstrando associação entre o valgo dinâmico e o sedentarismo (p<0,03). Não houve associação entre a dor e o valgo dinâmico do joelho (p>0,06) para ambos os grupos. Das mulheres sedentárias, 50,0% apresentaram escore FMS abaixo de seis pontos, representando alto risco de lesão. Conclui-se que mulheres sedentárias apresentam maior predisposição ao valgismo dinâmico do joelho, maior sintomatologia dolorosa e maior risco de lesão nos membros inferiores.

“…Table 3 describes the procedural aspects, the objectives, exercises, implements used, evaluation instruments, and results of the studies that were reviewed. From the eight included studies, the leg press exercise was used in three [4,13,14] and the other five performed the squat exercise [15][16][17][18][19].…”

Resistance training has been commonly used as a method of intervention in the rehabilitation of musculoskeletal injuries affecting the knee. Thus, the objective of this systematic review was to identify the methods employed with and without implements in leg press and squat exercises for the maintenance of knee alignment. The literature search was performed in the databases: PubMed, SciELO, and Lilacs. We used the descriptors "muscle strength" and "exercise" and their synonyms, available in the Health Sciences Descriptors (DeCS) and the Medical Subject Headings (MeSH), with the terms "valgus knee" and "varus knee". From the 1,117 articles found, eight studies were considered for the review. The included studies had samples composed of young men and women with advanced levels of training. Despite verifying conditions of valgus or varus knee, the studies presented different protocols and assessment methods. The implements comprised physioball, elastic resistance, and wedge. Electromyography and kinematics were used to assess muscle activity and movement patterns. These results reinforced the possibility of using implements to induce muscle and joint actions to reduce varus and valgus conditions. We suggest more studies to define the best strategies to reduce the excessive deviation of the patella in people who have valgus or varus knee.

“…Closed-chain kinetics exercises (CCF) are defined as those in which distal segments are supported on a surface, which limit movement and define a direction 1,2 . This modality of physical exercise requests the movement of more than one articulation for its effect 1 .…”

“…In addition to stimulating the proprioceptive system, CCF exercises require coactivation and co-contraction of both agonist and antagonist muscles, providing better joint stability 2,3 . For this reason, they are clinically safer and often indicated for knee joint rehabilitation programs because they reduce shear forces and cause lower stresses in joint structures under recovery 1,3,4 .…”

Comparative Analysis of the Effect of the Different Adaptations of the Squat Exercise on the Knee Frontal Plane Projection Angle

Closed kinetic chain exercises have been employed in rehabilitation and muscle strengthening programs, such as squatting. During the movement of the squat dynamic valgus, a change that affects all kinematics of the lower limb, tends to become exacerbated, necessitating adaptations in order to minimize the biomechanical disorder. Although studies have shown the effectiveness of squatting exercises, there is a lack of evidence to demonstrate, comparatively, the effectiveness of different adaptations in the decrease of dynamic valgus. The objective of the study was to evaluate to identify the efficacy of different adaptations in squatting exercise in the reduction of dynamic valgus. Therefore, study volunteers (n = 30) performed three types of squats: free squatting, squatting with elastic band and squatting with verbal command. The dynamic valgus wasmeasured by the knee frontal plane projection angle during the squatting movements, through captured images and analyzed by the software Tracker and ImageJ. Despite more cases in women, in both sexes, free squatting presented greater cases of medicalization of the knee than in comparison to the other two adaptations. Although both squat adaptations presented positive results, only squatting with verbal command showed a significant reduction of the dynamic valgus pointing out that this is the best adaptation treated.

Resumo Exercícios de cadeia cinética fechada vêm sendo empregados em programas de reabilitação e fortalecimento muscular, como é o caso do agachamento. Durante o movimento de agachamento o valgo dinâmico, alteração que afeta toda cinemática do membro inferior, tende a se tornar exacerbado, sendo necessárias adaptações com o intuito de minimizar o distúrbio biomecânico. Embora estudos tenham mostrado a eficácia dos exercícios de agachamento, faltam evidências que demonstrem, comparativamente, a efetividade de diferentes adaptações na minimização do valgo dinâmico. O objetivo do estudo foi identificar a eficácia de diferentes adaptações na execução do exercício de agachamento na redução do valgo dinâmico. Para tanto, os voluntários do estudo (n=30) três tipos de agachamentos: agachamento livre, agachamento com banda elástica e agachamento com comando verbal. O valgo dinâmico foi mensurado mediante o ângulo de projeção no plano frontal do joelho durante os movimentos de agachamento, através de imagens capturadas e posteriormente analisadas pelos softwares Tracker e ImageJ. Apesar de mais casos em mulheres, em ambos os sexos, o agachamento livre apresentou maiores casos de medicalização do joelho do que nas outras duas adaptações. Embora ambas adaptações de agachamento apresentaram resultados positivos, apenas o agachamento com comando verbal apresentou redução significativa do valgo dinâmico, apontando ser esta a melhor adaptação tratada.
