Anatomical glenohumeral internal rotation deficit and symmetric rotational strength in male and female young beach volleyball players.

Beach volleyball is a sport with a high demand of shoulder structures that may lead to adaptations in range of motion (ROM) and strength like in other overhead sports. Despite of these possible alterations, no study evaluated the shoulder adaptations in young beach volleyball athletes. The aim of this study was to compare the bilateral ROM and rotation strength in the shoulders of young beach volleyball players. Goniometric passive shoulder ROM of motion and isometric rotational strength were evaluated in 19 male and 14 female asymptomatic athletes. External and internal ROM, total rotation motion, glenohumeral internal rotation deficit (GIRD), external rotation and internal rotation strength, bilateral deficits and external rotation to internal rotation ratio were measured. The statistical analysis included paired Student's t-test and analysis of variance with repeated measures. Significantly lower dominant GIRD was found in both groups (p<0.05), but only 6 athletes presented pathological GIRD. For strength variables, no significant differences for external or internal rotation were evident. Young beach volleyball athletes present symmetric rotational strength and shoulder ROM rotational adaptations that can be considered as anatomical. These results indicate that young practitioners of beach volleyball are subject to moderate adaptations compared to those reported for other overhead sports.

Estudo retrospectivo de 71 casos de protrusão da glândula da terceira pálpebra (2009-2013) / Retrospective study of 71 cases of prolapsed third eyelid gland (2009-2013) / Análisis retrospectivo de 71 casos de prolapsos de glándula del tercer párpado (2009-2013)

Objetivou-se com esse estudo avaliar a incidência de protrusão da glândula da terceira pálpebra e correlacionar as características de raça e sexo com a lateralidade da alteração. Para isso, foram analisadas 3.151 fichas clínicas atendidas setor de oftalmologia veterinária da Universidade Estadual de São Paulo (UNESP) no período de 2009 a 2013, avaliando-se dados de incidência e lateralidade da afecção, além de idade, sexo e raça dos animais acometidos. Realizou-se a análise estatística de frequência e calculou-se o coeficiente de correlação de Spearman, considerando o nível de significância de 5%. Foram diagnosticados, no total, 71 casos de protrusão da glândula da terceira pálpebra em cães, correspondendo a 2,43% (71/2.916) da casuística de atendimento oftalmológico nesta espécie, porém não foi observado nenhum caso em gatos. Obteve-se uma maior frequência (58%, 41/71) em cães com idade inferior a 12 meses, sendo as raças mais acometidas: Lhasa Apso (24%, 17/71), Sem Raça Definida (20%, 14/71) e Beagle (14%, 10/71). Em 72% (44/71) dos casos a afecção se manifestou unilateral e 55% (39/71) dos animais eram fêmeas. Não houve correlação entre o sexo e a raça com a lateralidade da protrusão (p > 0,05). Com base no levantamento de dados realizados nesta instituição, conclui-se que a incidência da afecção é baixa em cães e rara em gatos, além de que não há influência do sexo e da raça com relação ao lado acometido pela alteração..

This paper aims to analyze the incidence of prolapsed third eyelid gland and correlate the breed and gender characteristics to the laterality of the alteration. In order to do this, three thousand one hundred and fifty-one (3151) medical records were analyzed at the Department of veterinary ophthalmology from the State University of São Paulo (UNESP) from 2009 to 2013, considering data such as the incidence and laterality of the disease, as well as age, gender and breed of affected animals. A frequency statistical analysis was performed and the Spearman correlation coefficient was calculated by taking the significance level of 5%. The prolapse of the third eyelid gland was diagnosed in 71 cases in dogs, which corresponds to 2.43% (71/2916) of the cases cared for in the ophthalmological assistance in this specie; however, no cases were observed in cats. Dogs younger than 12 months of age presented a higher frequency, (58%, 41/71). The breeds most affected were Lhasa Apso (24%, 17/71); Mongrel (20%, 14/71); and Beagle (14%, 10/71). The prolapse was unilateral in 72% (44/71) of the cases, and 55% (39/71) of the animals were female. There was no significant relation of gender and breed with the laterality of the prolapsed gland (p > 0.05). Therefore, it can be concluded that the incidence of the alteration is low in dogs and rare in cats, as well as no influence being related to gender and breed to the side affected by the alteration...

El objetivo de esta investigación ha sido evaluar la incidencia del prolapso de la glándula del tercer parpado y correlacionar las características de raza y sexo con la lateralidad de la alteración. Para tanto fueron analizadas 3151 fichas clínicas atendidas en el sector de oftalmología veterinaria de la Universidade Estadual de São Paulo (UNESP) entre 2009 y 2013, considerando datos de incidencia y lateralidad de la afección, además de edad, sexo y raza de los animales enfermos. Se realizó el análisis estadístico de frecuencia y fue calculado el coeficiente de correlación de Spearman, considerando el nível de significancia de 5%. Se ha diagnosticado 71 casos de prolapso de la glándula del tercer parpado en caninos, correspondiendo a 2,43% (71/2916) de la casuística del atendimiento oftalmológico en esta especie, sin embargo no se ha observado ningún caso en gatos. Hubo una frecuencia más grande (58%, 41/71) en perros con edad inferior a 12 meses, teniendo en cuenta que las razas que más presentaron este problema fueron Lhasa Apso (24%, 17/71), Sin raza definida (20%, 14/71) y Beagle (14%, 10/71). En 72% (44/71) de los casos, la afección se manifestó unilateral y 55% (39/71) de los animales eran hembras. No hubo correlación significativa entre el sexo y la raza con la lateralidad del prolapso (p > 0,05). Con base en el alzamiento de datos realizados en esta institución, se ha concluido que la incidencia de la afección es baja en perros y rara en gatos, además de no haber influencia del sexo y de la raza con relación al lado tomado por la alteración...

Comparison of hip rotation range of motion in judo athletes with and without history of low back pain.

This study compared hip rotation range of motion in judo athletes with and without a history of low back pain. Forty-two athletes (22 males) were divided into two groups: 21 with history of low back pain (HLBP) and 21 without history of low back pain (Control). Internal and external hip rotation range of motion in active and passive movement were measured using computed photogrammetry. The HLBP group exhibited a significant reduction in active internal rotation (27.5 ± 6.5°vs 38.2 ± 6.5°), active total rotation (80.1 ± 9.5°vs 87.4 ± 7.9°) of the non-dominant limb (P < 0.01) and active total rotation (82.6 ± 7.6°vs 87.6 ± 9.8°; P = 0.04) in comparison with the control group. In passive rotation, the HLBP group showed a significant reduction in internal rotation of the dominant (41.9 ± 6.1°vs 46.1 ± 8.4°; P = 0.04) and non-dominant limb (37.1 ± 8.4°vs 47.3 ± 7.6°; P < 0.001), total rotation of the non-dominant limb (96.7 ± 10.2°vs 105.1 ± 11°; P = 0.005) and total rotation (98.5 ± 9.2°vs 105 ± 11.2°; P = 0.02). Within the HLBP group, a significant reduction in both active and passive internal rotation (P < 0.001) and active and passive total rotation (P < 0.01) of the non-dominant limb was detected. The same was not found in the control group. The results demonstrate that judo athletes with a history of low back pain exhibit deficits in hip rotation and greater asymmetry between limbs.
