Previous issue date: 2009-07-07 / The purpose of the study was to compare hemiparetic gait overground and on the treadmill. Seventeen chronic stroke patients were included in the study. They walked overground and on a treadmill level at the same speed. The Qualisys Medical AB motion analysis system was used to quantify the joint kinematic of the paretic lower limb and the spatio-temporal parameters on the two conditions: overground walking and treadmill walking on three samples of 5-minutes. During the first sample, the subjects walked on the treadmill with greater cadence, shorter stride length, shorter step time on the lower paretic limb, greater range of motion in the hip and knee, greater knee flexion at the initial contact, more extension of the knee and lower dorsiflexion of the ankle at the stance phase. It is important to emphasize that the maximal knee flexion and ankle dorsiflexion just occurred later on the treadmill. Comparisons between each walking sample on the treadmill hadn t revealed any changes on the gait parameters over time. Nonetheless, when analyzing the third walking sample on the treadmill and overground, some variables showed equivalence as such as the total range of motion of the hip, the knee angle at the initial contact and its maximal extension at the stance phase. In summary, walking on a treadmill, even thought having some influence on the familiarization process, haven t demonstrated a complete change in its characteristics of hemiparetic chronic patients / Este estudo teve como objetivo comparar a marcha de indiv?duos hemipar?ticos no solo e em diferentes per?odos na esteira. Foram inclu?dos 17 indiv?duos hemipar?ticos cr?nicos, os quais deambularam sobre a esteira e solo com a mesma velocidade. O sistema se an?lise do movimento Qualisys Medical AB foi utilizado para quantificar as vari?veis angulares referentes ao membro inferior par?tico e as vari?veis espa?o-temporais nas duas condi??es: marcha no solo e marcha na esteira, sendo esta ?ltima realizada em 3 coletas de 5 minutos. Durante a primeira coleta os sujeitos deambularam na esteira com maior cad?ncia, menor comprimento da passada, menor tempo de passo com o membro inferior par?tico, maior amplitude de movimento para as articula??es do quadril e joelho, maior flex?o do joelho no contato inicial, maior extens?o do joelho e menor dorsoflex?o do tornozelo no apoio. Vale ressaltar que a m?xima flex?o do joelho e a m?xima dorsoflex?o do tornozelo no balan?o ocorreram tardiamente na esteira. Compara??es entre as coletas sobre esteira n?o demonstraram mudan?a na marcha no decorrer do tempo, entretanto, quando confrontada a terceira coleta na esteira com o solo, algumas vari?veis revelaram equival?ncia entre os meios como a amplitude total do quadril, o ?ngulo do joelho no contato inicial e sua m?xima extens?o no apoio. Desta forma, a marcha em esteira mesmo demonstrando uma certa influ?ncia do processo de familiariza??o, n?o apresentou uma mudan?a completa em suas caracter?sticas em indiv?duos com hemiparesia cr?nica
