Design: Observational descriptive study. Location: Laboratory of human movement analysis. Participants: Eighteen subjects, 10 men and 8 women were evaluated, with a mean age of 55.3 ? 9.3 years and the time since the injury of about 36 ? 22.8 months. Intervention: Not applicable. Main Outcome Measures: All subjects were evaluated for functional independence (Functional Independence Measure - FIM) and balance (Berg Balance Scale). Angular variations of the hips, knees and ankles in the sagittal plane were observed, as well as the speed of the movement (m/s), cadence (steps/min), stride length (m), cycle time (s), step time on the paretic leg and on the non-paretic leg (s), support phase time and balance phase time on the paretic leg (s) and the ratio of symmetry inter-limb as subjects walked on a treadmill at three conditions of inclination (0%, 5% and 10% ). Results: There were angular increases in the initial contact of the hip, knee and ankle, amplitude increase in the hip between 0% and 10% (37.83 ? 5.23 versus 41.12 ? 5.63, p < 0,001) and 5% and 10% (38.80 ? 5.96 versus 41.12 ? 5.63, p = 0,002), amplitude increases in the knee between 0% and 10% (47.51 ? 15.07 versus 50, 30 ? 12.82, p = 0,040), extension decreases in the hip, dorsiflexion increases in the balance phase and in the time of support phase from 0% to 5% (0.83 ? 0.21 versus 0.87 ? 0, 20, p = 0,011) and 0% and 10% (0.83 ? 0.21 versus 0.88 ? 0.23, p = 0,021). Conclusion: The treadmill inclination promoted angle changes as such as the increase of the angle of the hip, knee and ankle during the initial contact and the balance phase and the increase of the range of motion of the hip and knee; furthermore, it also promoted the increase of the support time of the paretic lower limb / Objetivo: Analisar os efeitos da inclina??o da esteira el?trica na marcha de indiv?duos com hemiparesia cr?nica. Desenho: Estudo observacional descritivo. Local: Laborat?rio de an?lise do movimento humano da UFRN. Participantes: Foram avaliados 18 indiv?duos, 10 homens e 8 mulheres, com m?dia de idade de 55,3 ? 9,3 anos e tempo de les?o de 36 ? 22,8 meses. Interven??o: N?o se aplica. Medidas: Todos os sujeitos foram avaliados quanto ? independ?ncia funcional (Medida de Independ?ncia Funcional - MIF) e equil?brio (Escala de Equil?brio de Berg). Foi observada a varia??o angular do quadril, joelho e tornozelo no plano sagital e tamb?m a velocidade da marcha (m/s), cad?ncia (passos/min), comprimento da passada (m), tempo do ciclo (s), tempo do passo da perna par?tica e n?o-par?tica (s), tempo de apoio e tempo de balan?o da perna par?tica (s) e raz?o de simetria entre membros enquanto os indiv?duos caminhavam na esteira em tr?s condi??es de inclina??o (0%, 5% e 10%). Resultados: houve aumento do ?ngulo no contato inicial do quadril, joelho e tornozelo, aumento da amplitude do quadril entre 0% e 10% (37,83 ? 5,23 versus 41,12 ? 5,63; p < 0,001) e 5% e 10% (38,80 ? 5,96 versus 41,12 ? 5,63; p = 0,002), aumento da amplitude do joelho entre 0% e 10% (47,51 ? 15,07 versus 50,30 ? 12,82; p = 0,040), diminui??o da extens?o do quadril, aumento da dorsiflex?o no balan?o e aumento no tempo de apoio entre 0% e 5% (0,83 ? 0,21 versus 0,87 ? 0,20; p = 0,011) e 0% e 10% (0,83 ? 0,21 versus 0,88 ? 0,23; p = 0,021). Conclus?o: A inclina??o da esteira promoveu altera??es angulares como o aumento do ?ngulo do quadril, joelho e tornozelo durante o contato inicial e a fase de balan?o e aumento da ADM do quadril e joelho, bem como aumento do tempo de apoio do membro inferior par?tico
