Stability of gait and interlimb coordination in older adults.
Most falls in older adults occur when walking, specifically following a trip. This study investigated the short- and longer term responses of young (n = 24, 27.6 ± 4.5 yr) and older adults (n = 18, 69.1 ± 4.2 yr) to a trip during gait at comfortable speed and the role of interlimb coordination in recovery from tripping. Subjects walked on a self-paced treadmill when forward movement of their do...
متن کاملInterlimb Coordination During Step-to-Step Transition and Gait Performance.
Most energy spent in walking is due to step-to-step transitions. During this phase, the interlimb coordination assumes a crucial role to meet the demands of postural and movement control. The authors review studies that have been carried out regarding the interlimb coordination during gait, as well as the basic biomechanical and neurophysiological principles of interlimb coordination. The knowl...
متن کاملInterlimb coordination deficits during cyclic movements in cerebellar hemiataxia.
The authors report a 35-year-old man whose unilateral cerebellar lesion resulted in marked deficits in coordinating simultaneous cyclic movements of the arm and leg on his ipsilesional side. He exhibited no such deficits when making simultaneous movements of the contralesional limbs or when moving paired left and right limbs. Thus, the cerebellum, which is already known to underlie within-limb ...
متن کاملDecentralized control mechanism underlying interlimb coordination of millipedes.
Legged animals exhibit adaptive and resilient locomotion through interlimb coordination. The long-term goal of this study is to clarify the relationship between the number of legs and the inherent decentralized control mechanism for interlimb coordination. As a preliminary step, the study focuses on millipedes as they represent the species with the greatest number of legs among various animal s...
متن کاملEffects of walking speed on gait stability and interlimb coordination in younger and older adults.
Many falls in older adults occur during walking following trips. Following a trip, older adults take longer than younger adults to recover steady-state walking. Although faster gait speed may improve interlimb coordination, it may also increase fall risk in older adults. We hypothesized that older adults would take longer than younger adults to recover from an unexpected perturbation during gai...
