“…In agreement with the previous studies (Dobbs et al, 1993;Hageman and Blanke, 1986;Himann et al, 1988;Imms and Edholm, 1981;Rubenstein et al, 1988;Murray et al, 1969;Wall et al, 1991;Trueblood and Rubenstein, 1991), our studies indicated that older adults walked slower than younger adults(120.22cm/s±10.12 Vs 133.23cm/s±11.59). There have been many suggestions for why older adults walk slower.…”

A laboratory study was conducted to evaluate if two different age groups(young vs. old) had differences in walking velocity and heel contact velocity and, furthermore, if these gait characteristics could adversely influence initial friction demand characteristics(i.e. RCOF) and the likelihood of slip-initiation. Twenty eight(14 younger and 14 older adults) participated in the study. While wearing a safety harness, all participants walked at their preferred gait speed for approximately 20 minutes on the linear walking track(1.5m×20m) consisting of two floor-mounted forced plates. During subsequent 20 minutes, synchronized ground reaction forces and posture data were captured using the two force plates and six infrared cameras, respectively. The results indicated that older adults walked slower(i.e., slower whole body center-of-mass velocity), exhibited lower heel contact velocity, and produced lower initial friction demand characteristics (i.e. RCOF) in comparison to younger adults. However, ANCOVA indicated that the differences in heel contact velocity between the two age groups were due to the effects of walking velocity. The bivariate analysis further suggested that walking velocity was correlated to RCOF and heel contact velocity, while heel contact velocity was not found to be correlated to RCOF. In conclusion, younger adults' RCOF was higher than their older counterparts due to faster walking velocity. As such, walking velocity could be a better indicator for predicting initial friction demand characteristics(i.e. RCOF) not heel contact velocity.

“…Slow walking speed in the elderly has been reported in many previous papers (Murray et al, 1969;Hageman and Blanke, 1986;Himann et al, 1988;Kaneko et al, 1991), and this slowness has been found to be mainly caused by short stride length (Imms and Edholm, 1981;Ferrandez et al, 1990;Nishizawa et al, 2000). Over the last century, differences in height have been observed between cohorts in developed countries (Kouchi, 1996).…”

The free gait of 52 healthy elderly persons was examined. All the subjects were volunteers, aged 65 years or older, and lived in the community in the Kaga area, Ishikawa Prefecture, Japan. They were healthy and active enough to attend the study location by themselves. The comparison group of young adults consisted of 20 volunteer students. The percentages of females and males were similar in the two groups. The healthy elderly walked more slowly than the young adults. Their slower speed was largely caused by their shorter stride length. Differences were still observed between the young and elderly groups when gait parameters were presented in the form of dimensionless numbers. The elderly were weaker in grip strength and had shorter single-leg balance with eyes open than the young adults. The number of steps per day correlated negatively with age within the elderly group. Negative correlations between age and walking speed, as measured directly or in terms of dimensionless numbers, and between age and stride length were also observed within the elderly group. The relative stance phase duration correlated positively with age within the elderly group. Slow speed may be related to low daily activity, reduced muscle power, and diminished balance ability. Long stance phase duration and slow speed in the elderly could be an adaptive characteristic in response to impaired balance.

“…A adoção de estratégias adaptativas no andar do idoso surge mediante a necessidade de compensar os déficits neuromusculares, como, por exemplo, a diminuição da velocidade, menor comprimento de passo, redução do tempo da fase de balanço e diminuição dos movimentos articulares do quadril, joelho e tornozelo (HAGEMAN et al, 1986;JUFGE;DAVIS;OUNPUU;1996;CHEN et al, 1991;HORTOBÁGYI, 2000;CHOU, 2004;CHOU, 2005;HORTOBÁGYI et al, 2009). Haja vista que a marcha não pode ser considerada um ato reflexo e sim um processo que requer associação de respostas cognitivas para gerar uma execução adequada, objetivamos com o presente estudo analisar a influência do medo de cair e da dupla tarefa sobre a variabilidade de variáveis cinemáticas e eletromiográficas da marcha de idosos para compreender os efeitos de sobrecargas relacionadas à tarefa durante o processo de deambulação (LUNDIN-OLSSON; NYBERG; GUSTAFSON, 1997;BEAUCHET et al, 2003;SALAMON;PRIEST, 2004).…”

O objetivo deste estudo foi investigar a influência do medo de cair e da dupla tarefa sobre a variabilidade de parâmetros eletromiográficos e cinemáticos da marcha de idosas. Dezessete universitárias (21,47 ± 2,06 anos) e dezoito idosas (65,33 ± 3,14 anos), fisicamente ativas, realizaram teste de marcha em três condições: velocidade de preferência; medo de cair; e dupla tarefa. A atividade eletromiográfica dos músculos do membro inferior dominante e o comprimento e tempo de passada foram registrados. Utilizou-se o teste ANOVA Two-Way (p<0,05). A variabilidade eletromiográfica e cinemática foram maior para o grupo de idosas na comparação entre grupos. Para a comparação entre as condições de marcha analisadas, houve diferença significativa apenas para variabilidade eletromiográfica. Assim, o aumento da variabilidade dos parâmetros EMG e cinemáticos do grupo de idosos em relação ao grupo de jovens sugere que o fator envelhecimento contribui para uma maior dificuldade no controle da marcha, o que possivelmente predispõe estes indivíduos à ocorrência de quedas.
