Resumo: | This work consists of two studies. The aim of the first study was to investigate quadriceps and hamstring muscle volumes and strength deficits of the knee extensors and flexors in people with chronic hemiparesis compared to a healthy group. Fifteen individuals with chronic stroke and fifteen healthy individuals took part in this study. Motor function, quadriceps and hamstring muscle volume (MV), and maximal concentric and eccentric contractions of the knee extensors and flexors were obtained. The quadriceps muscle showed a reduction in MV. The peak torque of the paretic and non paretic limbs knee extensors and flexors was reduced in both contraction modes and velocities. There were significant correlations between motor function and strength deficits. With regard to muscle mass, there was a difference between quadriceps and hamstring response. There was no disuse atrophy; however this did not prevent extensor torque reduction. The aim of the second study was to investigate the effects of ground level gait training combining body weight support (BWS) and functional electrical stimulation (FES). Twelve people following chronic stroke. An A1-B-A2 system was applied; A1 and A2 corresponded to ground level gait training using BWS, and B corresponded to the same training associated to FES. The analyzed variables were: mean walking speed of locomotion; step length; stride length, speed and duration; initial and final double support duration; single-limb support duration; swing period; range of motion (ROM), maximum and minimum angles of foot, leg, thigh, and trunk segments. Mean walking speed, stride length and speed increased. Regarding the ROMs, there was a significant increase for leg and thigh. There was not improvement in the variables measured during the FES phase. Ground level gait training using BWS was effective to improve some gait, and the association to FES did not provide any additional improvement in the measured parameters. |

O objetivo do primeiro estudo foi investigar os volumes dos músculos quadríceps e isquiotibiais e os déficits de força dos músculos extensores e flexores do joelho em hemiparéticos crônicos comparados a um grupo controle saudável. Quinze indivíduos com hemiparesia crônica e 15 indivíduos saudáveis fizeram parte do estudo. Foram obtidos: pontuação da função motora geral, volume muscular (VM) dos músculos quadríceps e isquiotibiais e contrações concêntricas e excêntricas dos músculos extensores e flexores do joelho. O músculo quadríceps do membro parético apresentou redução no VM comparado ao membro contralateral. Os picos de torque extensor e flexor dos membros parético e contralateral apresentaram-se reduzidos para ambos os modos de contração e ambas as velocidades e correlações entre a função motora e os déficits de força muscular foram encontradas. Observou-se que há diferentes respostas entre os músculos quadríceps e isquiotibiais com relação à massa muscular. Não foi observada atrofia muscular por desuso. Entretanto, esse fato não preveniu a redução do torque articular. O objetivo do segundo estudo foi investigar os efeitos de um treinamento de marcha, em piso fixo, associado ao suporte parcial de peso corporal (SPPC) e à estimulação elétrica funcional (EEF) do nervo fibular comum, em hemiparéticos crônicos. Participaram do estudo 12 hemiparéticos crônicos. O sistema adotado foi o A1-B-A2, no qual A correspondeu ao treinamento de marcha em piso fixo com SPPC e B ao mesmo treinamento associado à EEF. Foram analisadas: velocidade média de locomoção, comprimento do passo, comprimento, velocidade e duração da passada; duração dos períodos de apoio duplo inicial e final, apoio simples e balanço; ângulos máximos e mínimos e amplitude de movimento (ADM) dos segmentos pé, perna, coxa e tronco dos membros parético e não-parético. Houve um aumento na velocidade média e no comprimento e velocidade do ciclo. Com relação às ADMs, houve aumento significativo entre as avaliações para o segmentos: perna e coxa após. Não houve melhora nas variáveis mensuradas na fase de EEF. Concluímos que o treinamento com SPPC, em piso fixo, foi efetivo na melhora de alguns aspectos da marcha e a associação à EEF não promoveu melhora adicional dos parâmetros mensurados.Universidade Federal de Minas Geraisapplication/pdfporUniversidade Federal de São CarlosPrograma de Pós-Graduação em Fisioterapia - PPGFtUFSCarBRFisioterapiaHemiparesiaCinemáticaAvaliação isocinéticaTorqueIntervençãoAcidente Vascular EncefálicoVolume muscularForça muscularDinamômetro isocinéticoParâmetros espaço-temporaisÂngulos segmentaresStrokeMuscle volumeMuscle strengthIsokinetic dynamometerInterventionSpatial-temporal parametersSegmental anglesKinematicsCIENCIAS DA SAUDE::FISIOTERAPIA E TERAPIA OCUPACIONALEstudo das alterações no volume muscular, na função articular e na marcha de hemiparéticos crônicosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesis-1-115e61dfb-577e-4f3c-b5a5-8574f316a362info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINAL2959.pdfapplication/pdf1881236https://repositorio.ufscar.br/bitstream/ufscar/5115/1/2959.pdf0562673d7f2deff6e61218a2842d970dMD51THUMBNAIL2959.pdf.jpg2959.pdf.jpgIM Thumbnailimage/jpeg6291https://repositorio.ufscar.br/bitstream/ufscar/5115/2/2959.pdf.jpg516b2c2cc3152eda673428059a9a1babMD52ufscar/51152023-09-18 18:31:05.535oai:repositorio.ufscar.br:ufscar/5115Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:31:05Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
