Age-associated differences in the gait pattern changes of older adults during fast-speed and fatigue conditions: results from the Baltimore longitudinal study of ageing

Gait characteristics of younger-old and older-old adults walking overground and on a compliant surface

“…Frontal plane corrections maybe require a more complex coordination of muscle responses between the left and the right side and a greater demand on the processing requirements of the nervous system. It was observed a decline in gait speed and in mediallateral hip-generative mechanical work expenditure with age and the rate of decline was steeper for walking at fast speed revealed a lower trunk control during challenging dynamic balance tasks 21 . The ability to restrain lower trunk movements following disturbances imposed by environment may be a key determinant to the ability to avoid a fall 26 .…”

“…When walking on compliant surfaces, older and young adults decreased velocity and increased cadence 20 . A recent study observed an exacerbated decline in gait speed and medio-lateral control of the hip, which is explicitly evident during challenging walking 21 . To effectively walking on compliant surfaces, individuals with Parkinson's disease (PD) increased their stride length, step width, walking velocity and toe clearance and reduced the cadence.…”

Sex Differences and Impact of Body Mass Index on the Time Course of Knee Range of Motion, Knee Strength, and Gait Speed After Total Knee Arthroplasty

“…Although obtaining the average speed from multiple trials can help to reduce random error from intrapatient variation, patients performed only 1 trial of each test to minimize fatigue and knee discomfort. Furthermore, in this study, habitual and fast gait speeds were measured because habitual gait speed is a common physical performance measure used in clinical practice, while fast gait speed has been shown to correlate more closely with age and functional decline than does habitual gait speed in older adults (23,24).…”

The effect of aging on gait parameters in able-bodied older subjects: a literature review

“…In the elderly subjects, hip concentric powers during the stance phase were higher than those in young subjects despite their decreased ankle plantar flexor kinetics [22,28,45,46,49]. Cofre et al concluded that older subjects generated 46 % more hip work and 30 % more hip peak power than younger [46], while Devita et al stated 279 % more work in older subjects compared with younger [22].…”

“…The trunk-leading strategy used by elders resulted in a sense reversal of the low-back joint power curve and increased (p = 0.013) the mechanical energy expenditure (MWE) required for eccentric control of the lower trunk musculature during stance phase of gait Aging Clin Exp Res with younger [28,34,[44][45][46][47][48][49]. Decrease of ankle power has been shown to be 17 % [46] and 26 % [47]; moreover, in the assessment of ankle work in the elderly subjects, Cofre et al and Devita et al, respectively, reported 21 and 29 % less ankle work (p \ 0.05) than younger [22,46].…”
