“…Lu et al 16) reported similar results. Ankle plantarflexion in late stance was significantly decreased during obstacle crossing compared to during level walking (young group: linearly; elderly group: quadratically), and the elderly group, in particular, showed less plantarflexion than the younger group under all conditions ( Table 2).…”

“…Chen et al 15) studied obstacle height effects on foot clearance, crossing speed, horizontal distances, step length, and step width between healthy elderly and younger adults, but the obstacles were not normalized to the subjects' leg lengths. Lu et al 16) compared obstacle height effects on lower limb kinematics between two age groups, but they did not compare level walking with obstacle crossing.…”

Abstract.[Purpose] The purpose of this study was to investigate whether differences exist in the joint angle of the lower limbs and temporospatial parameters between healthy young adults and the elderly during level walking and crossing obstacles of 10%, 20%, and 30% of the leg length.[Subjects] Nine healthy young adults and 9 healthy elderly persons were recruited for this study.[Methods] Each subject was instructed to walk barefoot along a 9-m walkway, step over an obstacle and continue walking at a self-selected pace. The obstacle height was randomly selected for each trial.[Results] When crossing obstacles, support time for the trailing limb, stride length for the leading limb and step width showed no significant differences between the two groups. The maximum hip and knee flexion in mid swing of the trailing limb showed no significant difference between the two groups as well. The other gait parameters showed significant differences between the two groups.[Conclusion] Gait parameters showed that various strategies were used by the young adults and the elderly so as not to fall, when they crossed obstacles of different heights. In the future, a study with a larger sample size will be needed to verify our current findings.

“…In self-paced movements, both postural adjustments and voluntary limb movements appear to be parts of the same motor program (Lee et al, 1987;Zattara & Bouisset, 1988). Stepping over obstacle as voluntary behavior requires planned locomotor adjustments to ensure safe circumvention of the obstacle Austin et al, 1999;Lu et al, 2006). These adjustments made prior to and over the obstacle are based on the anticipation of the obstacle(s) characteristics, including location, shape and height.…”

“…10,18 A marcha tem sido investigada sob diversas condições de visão, iluminação e com variação da tarefa, para análise das modulações do indivíduo durante a locomoção e também nas diferentes fases do desenvolvimento. 11,[19][20][21] Porém, são ainda insuficientes os estudos referentes ao desenvolvimento do andar em terrenos irregulares, ou com obstáculos.…”

Resumo:O comportamento locomotor de 25 crianças, na faixa etária de dois a seis anos, foi observado durante o andar em circuito com obstáculos, sob iluminação normal e reduzida. Os participantes foram instruídos a percorrer o circuito andando o mais rápido possível evitando o contato com os obstáculos. Duas variáveis dependentes foram coletadas: taxa de sucesso e tempo total para percorrer o circuito. As ANOVAs two-way (5 grupo-etário) x (2 iluminação), com medidas repetidas no último fator revelaram apenas efeito principal de grupo para a taxa de sucesso (F 4,20 = 9,975; p = 0,001), menor para as crianças de 2 anos em relação aos demais grupos, e para o tempo para realizar a tarefa (F 4,20 = 3,136; p = 0,037), maior para as crianças de 2 anos em relação às de 4 e 6 anos. Análises de Regressão Múltipla (stepwise) revelaram que: idade cronológica, grupo etário, tempo de experiência de andar e tempo gasto para percorrer o circuito predisseram 75,3% da taxa de sucesso; a taxa de sucesso foi a única variável que significativamente predisse o tempo despendido (R 2 = 0,372; p = 0,001). Estes resultados permitiram concluir que variáveis desenvolvimentais interferem no comportamento locomotor no circuito com obstáculos e que os ní-veis de iluminação não foram suficientes para causar perturbação na realização da tarefa.
