Asociación entre el nivel de funcionalidad y la fuerza funcional en miembros inferiores en adultos mayores en comunidad.

Gomez Pastor, Luisa, Taicas Montesinos, Marianella Shirley 08 December 2020 (has links)
Objetivo: Establecer la asociación entre el nivel de funcionalidad y la fuerza miembros inferiores en adultos mayores en comunidad. Materiales y métodos: Se realizó un estudio de transversal analítico en una comunidad de adulto mayor en Lima Perú. La población está conformada por adultos mayores de 60 años. Las variables de resultado fue la funcionalidad y las de exposición fueron la fuerza funcional en miembros inferiores y como confusoras el equilibrio y la masa magra apendicular para ello se aplicaron 6 pruebas. La primera evalúa la funcionalidad en general del adulto mayor mediante el SF-36, el cual abarca 8 dimensiones como funcionamiento físico, rol físico, dolor corporal, salud general, vitalidad, funcionamiento social, rol emocional y salud mental, el segundo evalúa la funcionalidad de miembros inferiores del adulto mayor. El tercero es el test de cinco veces pararse de sedente, que evalúa la fuerza muscular funcional de miembros inferiores. Para la medición de las variables confusoras utilizamos: El test de alcance máximo que mide la flexibilidad de miembros inferiores. Ponte de pie y anda que mide el equilibrio dinámico, coordinación y velocidad. Finalmente, se midió la masa muscular de miembros inferiores con la fórmula de Masa magra apendicular esquelética (MMAE). La recolección de datos se realizó con 2 personas y la muestra fue estratificada en edad y sexo. Se evaluó a cada participante en un ambiente específico para las evaluaciones en la misma comunidad de adulto mayor. Resultados: Se encontró asociación estadísticamente significativa entre la funcionalidad de miembros inferiores y la fuerza funcional de miembros inferiores (β =-0.642, p=0.003). Asimismo, otras variables que estuvieron asociadas a la funcionalidad de miembros inferiores son flexibilidad (p=0.006) y caídas (p=0.001). Conclusión: En el presente estudio fue realizado en Lima Perú; en el distrito de Molina Centro Integral del adulto mayor (CIAM) se encontró que existe asociación entre el nivel de funcionalidad de miembros inferiores con la fuerza funcional de miembros inferiores en adultos mayores. Asimismo, las variables caídas y flexibilidad también estuvieron relacionadas con el nivel de funcionalidad. / Objective: establish the association between the level of functionality and the lower member force in community older adults. Materials and methods: An analytical cross-sectional study was conducted in an older adult community in Lima Peru. The population is made up of adults over 60 years. The outcome variables were the functionality and the exposure variables were the functional force in the lower limbs and as balance the balance and the appendicular lean mass for this purpose, 6 tests were applied. The first assesses the functionality of the elderly in general through the SF-36, which covers 8 dimensions such as physical functioning, physical role, body pain, general health, vitality, social functioning, emotional role and mental health, the second evaluates functionality of lower limbs of the elderly. The third is the five-times sit to stand test, which evaluates the functional muscle strength of the lower limbs. For the measurement of confusing variables, we use: The maximum range test that measures the flexibility of lower limbs. Stand up and walk that measures dynamic balance, coordination and speed. Finally, the lower limb muscle mass was measured with the skeletal appendicular lean mass (MMAE) formula. Data collection was performed with 2 people and the sample was stratified in age and sex. Each participant was evaluated in a specific environment for assessments in the same senior community. Results: A statistically significant association was found between lower limb functionality and lower limb functional strength (β = -0.642, p = 0.003). Likewise, other variables that were associated with lower limb functionality are flexibility (p = 0.006) and falls (p = 0.001). Conclusions: In the present study, it was made in Lima Peru; In the district of Molina Centro Integral for the Elderly (CIAM) it was found that there is an association between the level of functionality of the lower limbs and the functional strength of the lower limbs in older adults. Likewise, the variables falls, and flexibility were also related to the level of functionality. / Tesis

No. of bitstreams: 1 SILVANA DA SILVA RODRIGUES.pdf: 983315 bytes, checksum: 17ccfa7762b3ec7758b0c81b7ca259bf (MD5) Previous issue date: 2011-01-28 / The main purpose of this dissertation was to construct lower and upper bounds for the cardinality of the error correcting codes for constant-weight, contained in the vector space Fn 3 , where F3 is a field with three elements, knowing parameters such as length and minimum distance code. We present the main results of linear algebra necessary to develop the theory of codes and then the fundamental concepts of more practical class of codes, the linear error correcting codes. We state the Totobola problem and the Football problem, relating them to the theory of codes and present some bounds for the "covering radius problem"for r = 1 , some values of n. In the last chapter, we conclude the work with some examples that illustrate bounds of coverings for Fn 3 , with r = 2 and 3, and the generalization of the problem, where we present the binary covering radius problem, the case of multiple coverages and the extension of the idea, citing bounds for the cardinality of the codes contained in the vector space over a finite field with any arbitrary number of elements. / O principal objetivo desta dissertação foi construir limitantes inferiores e superiores para o número de elementos de um código corretor de erros de peso constante, contido no espaço vetorial Fn 3 , onde F3 é um corpo contendo três elementos, a partir de parâmetros como comprimento e distância mínima do código. Apresentamos os principais resultados da álgebra linear necessários ao desenvolvimento da teoria de códigos e em seguida, os conceitos fundamentais da classe de códigos mais conhecida na prática: os códigos lineares. Definimos os problemas do totobola e da piscina de futebol e a relação de ambos, com a teoria de códigos e com o problema do raio de cobertura. Construímos limitantes para o problema do raio de cobertura para r = 1, a partir da variação de n, e no último capítulo o trabalho é finalizado com a apresentação de exemplos que ilustram limitantes de cobertura para Fn 3 , com r = 2 e 3 e a generalização do assunto, onde apresentamos o problema binário do raio de cobertura, o caso das múltiplas coberturas e a extensão da idéia, citando limitantes para o número de elementos de códigos contidos em espaços vetoriais sobre um corpo finito contendo uma quantidade qualquer de elementos.
