Postural stability is necessary for all human activities. Management od postural control is provided especially by central nervous system. For management are essential afferent information from vestibular, visual and somatosensory system. Modification of any of these inputs could have influence postural stability. Changes of exteroceptive perception can be achieved by the application of kinesio tape. Kinesiotaping is currently very popular therapeutic method, which is attributed to the wide range of effects. In the theoretical part of this thesis are described these effects, including the results of scientific studies that are engaged in verify the effects. Experimental part of this thesis was focused on the objectification of any changes of postural stability after application of kinesio tape on dorsal and ventral side of the trunk in healthy individuals without injury or other disorders. For the examination were used two tests of Balance Master® System, the modified clinical test of sensory interaction on balance and the test limits of stability. The results were satistically evaluated at the level α = 0.05. Due to kinesio tape were observed no siginificant changes in the mean sway velocity of center of gravity. There were also found no significant changes of parameters that evaluate the transmission of...

Introduction: Spinocerebellar ataxia (SCA) is currently defined as a group of diseases with progressive cerebellar syndrome, which manifests distinctively by ataxic stance and gait. In patients with SCA, deterioration of postural control occurs due to changes of pathophysiological degenerative nervous system. Control of postural stability is significantly influenced by somatosensory afferentation of soft tissue of foot. The work objective is to determine the effect of deep foot massage on postural stability in the group of patients and to compare obtained results with experiments without deep foot massage. Methods: Seven patients of the Clinic Rehabilitation at the Faculty Hospital, Prague Motol (average age 51.9 ± 13.9 years, 5 men, and 2 women) with SCA and clinical signs of cerebellar ataxia were participated in this study. All patients were examined using posturography before and after application of deep foot massage. Measurements were conducted on a firm surface, foam pad with open and closed eyes. Length of COP trajectory, COP area and COP velocity were measured. Results: Significantly lower values of the length and COP velocity were found on the foam pad with closed eyes, when the deep foot massage was applied. Experiments without applications of the deep foot massage did not show any...

The diploma thesis summarizes physiology of vestibular system and disorders of vestibular system. In experimental part we observe the influence of vestibular stimulation on static postural stability. We achieve vestibular stimulation by active and repeated head and body movements. We measure the lenght of COP trajectory using stabilometry. We tested two groups of persons, 20 healthy persons aged 21 - 49 years and 6 patients with postural stability disorder from vestibular origin aged 40 - 76 years. The changes in lenght of trajectory COP after vestibular stimulation were not statistically significant in any group, but for each patient, there was a change in lenght of trajectory of COP. In patients, who have peripheral vestibular disorder, there was a reduction in lenght of trajectory of COP. Powered by TCPDF (www.tcpdf.org)

INTRODUÇÃO. A força muscular e o equilíbrio do tronco são os aspectos mais importantes para a determinação da classificação funcional de atletas de basquetebol em cadeira de rodas. O objetivo deste estudo foi analisar e correlacionar a força muscular e os limites de estabilidade do tronco de acordo com a classificação funcional para atletas de basquetebol em cadeira de rodas. MÉTODOS. Quarenta e dois atletas, com classificação funcional homologada pela federação paulista da modalidade, distribuídos nas quatro classes do Basquetebol em Cadeira de Rodas (Classe 1 n= 11; Classe 2 n=11; Classe 3 n= 9; Classe 4 n=11) com média de idade de 28,3±7.4 (16-46) anos, do sexo masculino tiveram a força muscular e equilíbrio de tronco avaliados. A força do tronco foi avaliada nos músculos extensores e flexores utilizando o dinamômetro isocinético Biodex® de forma isométrica com 15 º de amplitude. Os atletas realizaram uma série de 10 repetições com 15 segundos de descanso entre cada repetição. O equilíbrio do tronco foi avaliado no equipamento Balance Master® e o teste utilizado foi o de Limites de Estabilidade (LOS) de forma adaptada. Os atletas, sentados em um banco, realizaram movimentos voluntários do tronco em oito direções no plano frontal e lateral. Os movimentos foram feitos no sentido horário, ao redor de um perímetro, visualizado pelo paciente em um monitor e que representa o limite de 100% de deslocamento dado pelo equipamento. RESULTADOS. Considerando a distribuição dos atletas nas classes, houve diferença significativa na comparação dos índices de força muscular e equilíbrio entre as classes 1x3; 1x4 e 2x4. Houve correlação negativa (moderada) entre a força muscular do tronco em flexão e o DM (r=-.68, p=.02. Houve correlação positiva (forte) na classe 3 da força muscular do tronco em extensão e o DM (r=.92 p=0,001). CONCLUSÃO. A força muscular isométrica de flexão e extensão do tronco e os índices de equilíbrios de VD e DM nas direções anterior, posterior aumentam progressivamente com as classes e apresentam maiores diferenças na comparação entre as classes 1 e 3 e 1 e 4 e 2 e 4. Não houve correlação entre a força muscular isométrica dos flexores e extensores do tronco e os limites de estabilidade de acordo com a classificação funcional do BCR / BACKGROUND. Trunk muscle strength and balance are very important in defining the class of wheelchair basketball (WCB) athletes. This study aims to correlate and analyze trunk muscle strength and balance among high-performance Brazilian WCB athletes with their functional classification. METHODS. Forty-two male athletes of mean age 28.3±7.4 years (16-46) were divided into four groups based on WCB classes as follow: class 1 n=11; class 2 n=11; class 3 n=9; and class 4 n=11. The athletes performed a set of 10 repetitions of trunk flexion and extension with 15 seconds of rest between each repetition using the BiodexR isokinetic dynamometer in isometric form, with amplitude 15° to evaluate trunk muscle strength. In order to evaluate trunk balance, using the Balance Master® equipment and the Limits of Stability test (LOS), the athletes made voluntary trunk movements in eight directions (clockwise) in the frontal and lateral planes while seated on a bench. During the test, the athletes could view the movements on a monitor that represented the 100% displacement limit given by the equipment. RESULTS. There were significant differences in comparisons of trunk muscle strength and LOS in the classes 1vs.3, 1vs.4 and 2 vs.4. There was moderate negative correlation between trunk muscle strength in flexion and maximum excursion (r=-0.68; p=0.02). There was a strong positive correlation in class 3 between trunk muscle strength in extension and maximum excursion (r=0.92;p= 0.001). CONCLUSION. There was no correlation of isometric trunk muscle strength in flexion and extension and LOS indices, according to the functional classification of the WCB athletes

Introdução: Com o aumento da idade, estudos demonstram que a população experimenta um declínio de sistemas fisiológicos participantes no controle da estabilidade postural. Dentre os métodos de avaliação descritos na literatura, encontra-se o Pull Test (PT), que é amplamente utilizado em escala mundial para avaliação do equilíbrio em indivíduos com doença de Parkinson. O teste examina a resposta do corpo a um deslocamento corporal posterior, oferecendo um identificador útil da estabilidade postural do indivíduo. O padrão de ativação muscular durante a realização do PT não foi ainda estudado. Objetivo: analisar o padrão da atividade eletromiográfica durante a realização do PT, em indivíduos hígidos acima de 40 anos de idade. Métodos: Vinte e três indivíduos hígidos realizaram o estudo eletromiográfico (EMG) de superfície dos músculos tibial anterior, gastrocnêmio medial e bíceps femoral durante a realização do PT. O PT e registros eletromiográficos foram realizados sucessivamente por 10 vezes em cada indivíduo. Os indivíduos foram também avaliados pelo Montreal Cognitive Assessment (MoCA). Resultados: O registro EMG mostrou que a atividade muscular inicia pelo tibial anterior, sendo seguida sucessivamente pelo gastrocnêmio medial e bíceps femoral. A frequência do número de passos para a manutenção da estabilidade postural foi de 93,9% para 1 ou 2 passos e 6,1% para 3 passos ou mais. A latência para ativação muscular foi relacionada com o desempenho cognitivo no MoCA. Pacientes com escores no MoCA inferior a 26 apresentavam maior latência do tibial anterior (p=0,03) e do bíceps femoral (p=0,02). Além disso, a amplitude do gastrocnêmio medial relacionou-se inversamente com o índice de massa corporal (IMC) (p=0,01). Conclusão: Constatou-se que o declínio da função executiva e o sobrepeso estão relacionados com mudanças nas respostas 12 neurofisiológicas durante a realização do PT. Os mesmos podem contribuir para prejuízos da estabilidade postural nestes indivíduos. / Background: Physiologic systems that participate of the postural stability control are impaired with aging. Pull Test (PT) is an assessment method widely worldwide utilized for evaluating the balance in individuals with Parkinson’s disease. The test examines the body’s response to a posterior bodily displacement, offering a useful identifier of the individual’s postural stability. The pattern of muscle activation during the PT has not yet been studied. Objective: the objective of this study was to analyze the pattern of electromyographic activity during the PT, in healthy individuals, over 40 years of age. Methods: Twenty three healthy individuals have carried out an electromyographic (EMG) study of the tibialis anterior, gastrocnemius medialis and biceps femoris muscles during the PT. The PT and the electromyographic recordings have been taken successively for 10 times in each individual. The individuals cognition have been assessed by the Montreal Cognitive Assessment (MoCA). Results: The EMG recording has showed that the muscle activity begins by the tibialis anterior, being successively followed by the gastrocnemius medialis and by the biceps femoris. The rate of the number of steps for keeping the postural stability was 93.9% for 1 or 2 steps, and 6.1% for 3 or more steps. The latency for muscle activation was related to the cognitive performance in the MoCA. Patients with MoCA scores lower than 26 have presented a larger latency in the tibialis anterior (p=0.03), and in the biceps femoris (p=0.02). Furthermore, the amplitude of the gastrocnemius medialis has been inversely related to the body mass index (BMI) (p=0.01). Conclusion: It has been found out that the decline in the executive function and overweight related to changes in the neurophysiologic 14 response during the taking of the PT. These may contribute for the losses of postural stability in such individuals.
