Evaluation of movements of lower limbs in non-professional ballet dancers: hip abduction and flexion

Abstract

BackgroundThe literature indicated that the majority of professional ballet dancers present static and active dynamic range of motion difference between left and right lower limbs, however, no previous study focused this difference in non-professional ballet dancers. In this study we aimed to evaluate active movements of the hip in non-professional classical dancers.MethodsWe evaluated 10 non professional ballet dancers (16-23 years old). We measured the active range of motion and flexibility through Well Banks. We compared active range of motion between left and right sides (hip flexion and abduction) and performed correlation between active movements and flexibility.ResultsThere was a small difference between the right and left sides of the hip in relation to the movements of flexion and abduction, which suggest the dominant side of the subjects, however, there was no statistical significance. Bank of Wells test revealed statistical difference only between the 1st and the 3rd measurement. There was no correlation between the movements of the hip (abduction and flexion, right and left sides) with the three test measurements of the bank of Wells.ConclusionThere is no imbalance between the sides of the hip with respect to active abduction and flexion movements in non-professional ballet dancers.

Characteristic Poses in Ballet in the Case of a Retired Classical Ballerina after Bilateral THA: A Case Report and Review of Literature

“…Valenti et al [19] stated that the more the dancer externally rotates the hip, the greater the hip abduction will be. In the present case, postoperative hip ROM was measured and showed flexion 110°/115°, external rotation 45°/45°, internal rotation 30°/30°, and abduction 45°/45°on the bed for medical examination.…”

Efeitos de diferentes tempos de alongamento na flexibilidade de bailarinas

“…Em uma pesquisa realizada com dez bailarinas não profissionais, objetivou-se avaliar a diferença de flexibilidade do membro inferior direito e esquerdo, nos movimentos de abdução e flexão de quadril, por meio de avaliação com goniômetro e banco de Wells. O resultado mostrou que houve uma pequena diferença em relação ao membro direito e esquerdo, porém sem significância estatística 24 .…”

Influência Da Fisioterapia Aquática Na Flexibilidade De Idosos Hipertensos E Diabeticos

“…O teste de sentar e alcançar foi proposto originalmente por Wells e Dillon em 1952, conforme a padronização canadense para os testes de avaliação da aptidão física com o banco de Wells do Canadian Standardized Test of Fitness (CSTF). É considerada uma medida linear que consiste em mensurar seus resultados em centímetros com ajuda de uma escala métrica fixada no banco (MOESCH et al, 2014;VALENTI et al, 2011). O teste de flexibilidade foi realizado com banco de Wells da marca WSC com medidas 30,5 cm x 30,5 cm x 30,5 cm com uma escala de 58,0 cm em seu prolongamento, sendo que o ponto zero se encontra na extremidade mais próxima do avaliado.…”
