Equilíbrio Postural em Crianças com Deficiência Intelectual / Postural Balance in Children with Intellectual Disabilities

Crianças com deficiência intelectual podem apresentar problemas estruturais e de maturação ligados ao sistema nervoso central, vestibular e proprioceptivo, sendo caracterizados pela escolha da estratégia motora e de equilíbrio postural inadequadas ou em atraso para a sua idade cronológica. Este estudo objetivou avaliar o equilíbrio postural em crianças com deficiência intelectual. Trinta crianças de ambos os sexos, com idade entre 7 a 13 anos, foram divididas em dois grupos, sendo quinze com deficiência intelectual (grupo DI) e quinze com desenvolvimento típico (grupo controle GC). O equilíbrio postural foi avaliado sobre a plataforma de força BIOMEC400 em apoio bipodal e unipodal. Os seguintes parâmetros de equilíbrio, baseados no centro de pressão (COP), foram analizados: área de elipse do COP, velocidade de oscilações do COP e frequência de oscilações do COP, nas direções antero-posterior (AP) e médio-lateral (ML). Os parâmetros de equilíbrio baseados no COP mostraram diferenças significativas entre os grupos em apoio bipodal para a velocidade média AP (DI=2,56; GC=3,55; p=0,02) e ML (DI=2,58; GC=3,59; p=0,03) e para frequência média AP (DI=0,53; GC=0,77; p=0,008). No teste em apoio unipodal, a frequência média AP foi a única variável a apresentar diferença significante entre os grupos (DI=0,85; GC=1,06; p=0,03). O grupo de participantes com deficiência intelectual apresenta, tanto em apoio bipodal como unipodal, resultados semelhantes ou superiores ao grupo controle. Estes resultados mostram que a deficiência intelectual não influenciou o equilíbrio postural estático em crianças de 7 a 13 anos.(AU).

Children with intellectual disability may present structural and maturation disorders associated with the central nervous system, proprioceptive and vestibular system. These children are characterized by the inappropriate choice or dalayed response in motor strategy and postural balance for their chronological age. The purpose of this study was to evaluate the postural balance in children with intellectual disability. Thirty children of both sexes, aged between 7 and 13 years, were divided in two groups, fifteen with intellectual disability (group ID) and fifteen with typical development (control group CG). The postural balance was evaluated based on the force platform BIOMEC400 in bipodal and unipodal support. The main balance parameters analyzed were: ellipse area of the pressure center (COP), mean velocity and mean frequency of COP oscillations, in both directions of the movement anteroposterior (AP) and mediolateral (ML). The balance parameters based on COP revealed significant differences between the groups in bipodal support to the mean velocity AP (ID=2,56; CG=3,55; p=0,02) and ML (ID=2,58; CG=3,59; p=0,03) and to mean frequency AP (ID=0,53; CG=0,77; p=0,008). In the unipodal support test, the mean frequency AP was the only that showed significant difference between groups (ID=0,85; CG=1,06; p=0,03). The intellectual disability group achieved in both bipodal and unipodal support, similar or better results than the control group. These results indicate that the intellectual disability did not influence the static postural balance in children from 7 to 13 years old. (AU).

Proprioceptive evaluation in healthy women undergoing Infrared Low Level Laser Therapy

Abstract Aim To evaluate if the application of infrared low-level laser therapy (LLLT) alters proprioception in young women. Methods 26 female volunteers were evaluated statically and dynamically by means of electronic baropodometry in the variables: distance from the foot center, maximum and medium pressure, and surface. Proprioception was also functionally assessed by the Star Excursion Balance Test (SEBT). The intervention occurred in two distinct periods, separated by one week apart, as this was a crossover study, so volunteers were submitted to placebo or LLLT (830 nm, 8 J/cm2), on the muscles: gastrocnemius, soleus, tibialis previous and long and short fibular. Results the analysis of baropodometry for both dynamic and static found no significant differences for the intervention group and the control group. Similar results were observed for SEBT. Conclusion The application of the LLLT, in the proposed parameters, did not influence the proprioception in young women.(AU)

Efecto de un programa de entrenamiento físico basado en la secuencia de desarrollo sobre el balance postural en futbolistas: ensayo controlado aleatorizado / Effect of physical training based on the developmental sequence of postural balance in football players: randomized controlled trial

Antecedentes. En la actividad deportiva, el balance postural es requerido para mantener la estabilidad durante el juego. Por tanto, existe una necesidad de determinar si el aprendizaje motor desde posiciones funcionales, movimientos coordinados están implicados en los deportes. Objetivo. El objetivo de este estudio fue determinar el efecto de un entrenamiento físico basado en la secuencia de desarrollo sobre el balance postural en futbolistas de la selección de la Universidad Nacional de Colombia, sede Bogotá. Materiales y métodos. Ensayo controlado aleatorizado de 19 hombres adultos jóvenes pertenecientes al equipo de futbol de la Universidad Nacional de Colombia, sede Bogotá. Los participantes fueron aleatorizados y asignados a dos grupos, un grupo intervención (n=11), en el cual se le aplicó un entrenamiento físico basado en la secuencia de desarrollo y un grupo control (n=8) el cual realizó un programa de entrenamiento convencional de futbol. Resultados. Existe homogeneidad entre los dos grupos, en el test de balance dinámico SEBT los valores obtenidos (P<0,5), demuestran una mejoría en todas las direcciones evaluadas tanto en el miembro inferior derecho como en el izquierdo. En el grupo de intervención, la relación intragrupal muestra una correlación 3:1 siendo una medida de protección. Conclusión. La aplicación de un programa de entrenamiento físico basado en la secuencia de desarrollo genera importantes mejoras en el balance estático y dinámico. Se demuestran mejoras en las distancias de excursión lo cual se puede relacionar con un aumento del control postural dinámico.

Background. Postural balance is required to maintain stability during the course of the game. Objective. The aim of this study determine the effect of physical training based on the developmental sequence of postural balance in players of the selection of the Universidad Nacional de Colombia in Bogotá. Materials and methods. A randomized controlled trial of 19 young adult males of the football team at the Universidad National of Colombia. Participants were randomly assigned to two groups, intervention group (n=11) which fitness program based on the sequence of development and a control group (n=8). Results. Homogeneity between the two groups, the dynamic balance test SEBT p-values obtained <0.5 which confirms an improvement in all evaluated directions both in the right leg as in the left leg. In the intervention group, intra group relationship shows a 3:1 correlation which represents a measure of protection as per 3 subjects improved in the intervention group improved 1 in the control group. Discussion. The purpose of this study was to evaluate the effect of a physical training program of 6-week, supervised, progressive, based on the sequence of development, dynamic and static balance in male soccer players. The results have shown improvements in excursion distances, which can be associated with an increased dynamic postural control. Conclusions. The use of a fitness program based on the sequence of development generates significant improvements in static and dynamic balance.
