Visually guided locomotion was studied in an experiment which human subjects (N = 8) had to accurately negotiate a series of irregularly spaced stepping-stones while infrared reflectometry and electrooculography were used continuously record their eye movements. On average, 68% saccades made toward the next target footfall been completed (visual capture occurred) foot be positioned still on ground; remainder first 300 ms swing phase. The subjects' gaze remained fixed target, until 51 after...
In the present study, 2 related hypotheses were tested: first, that vision is used in a feedforward control mode during precision stepping onto visual targets and, second, oculomotor and locomotor centers interact to produce coordinated eye leg movements task. Participants' (N = 4) step cycle transition events monitored while they performed task requiring precise foot placement at every irregularly placed stones under conditions which availability of information was either restricted or...
Abstract The authors quantitatively described gaze behavior of young (n = 10) and older adults during stair negotiation, which is information that crucial for understanding the underlying visuomotor control walking effects aging on this control. Both age groups spent majority time looking at central aspects stairs approximately 3 steps ahead. Older showed less variability in extent to they looked ahead (p < .05), all participants fixated briefer periods descent as opposed ascent .001)....
Background. Community-dwelling, chronic stroke survivors are at risk of falling during turning and more likely to sustain a hip fracture when they fall. Objective. This study quantifies kinematic differences between (mean ± SD: 38.3 31.3 months poststroke, 59.9 10.1 years age), with (n = 9) without falls history 9), age-matched healthy counterparts 18) in coordination the 180° turn around Timed “Up & Go„ (TUG) test. Methods. Full-body kinematics were recorded while participants performed...
Older adults deemed to be at a high risk of falling transfer their gaze from stepping target earlier than low-risk counterparts. The extent premature increases with task complexity and is associated decline in accuracy. This study tests the hypothesis that increased anxiety about upcoming obstacles (a) transfers toward (i.e., looking away box prior completing step on it order fixate future constraints walkway) (b) reduced accuracy older adults.High-risk (9) (8) adult participants walked 10-m...
Safe stair negotiation is an everyday task that children with developmental coordination disorder (DCD) are commonly thought to struggle with. Yet, there currently a paucity of research supporting these claims. We investigated the visuomotor control strategies underpinning in (N = 18, age 10.50 ± 2.04 years) and without 16, 10.94 2.08 DCD by measuring kinematics, gaze behavior state anxiety as they ascended descended staircase. A questionnaire was administered determine parents' confidence...
