Staying Upright by Shutting Down? Evidence for Global Suppression of the Motor System when Recovering Balance
Publication date: Available online 20 March 2019Source: Gait & PostureAuthor(s): Caleigh Goode, David M. Cole, David A.E. BoltonAbstractBackgroundWhen automatic, yet unwanted action is quickly inhibited, short-lived suppression throughout the motor system ensues. This effect is referred to asglobal suppression. Although response inhibition is essential for behavioral flexibility, widespread motor suppression may delay action reprogramming. In reactive balance control, even fleeting suppression...

Changes in the Control of Obstacle Crossing in Middle Age Become Evident as Gait Task Difficulty Increases
Publication date: Available online 16 March 2019Source: Gait & PostureAuthor(s): B.C Muir, J.M. Haddad, R.E.A. van Emmerik, S. RietdykAbstractBackgroundAge-associated physiological changes result in modified gait, such as slower speed, for older adults. Identifying the onset of age-related gait changes will provide insight into the role of aging on locomotor control. It is expected that a more challenging gait task (obstacle crossing) puts more demands on physiological systems, and may reveal...

Contribution of vision and its age-related changes to postural stability in obstacle crossing during locomotion
Publication date: Available online 15 March 2019Source: Gait & PostureAuthor(s): Sho Kunimune, Shuichi OkadaAbstractBackgroundObstacle crossing requires sufficient toe clearance for trip and fall prevention for which postural stability is a prerequisite. It is thought that the upper visual field plays an important role in the maintenance of postural stability, but its influence and age-dependence have not been investigated yet.Research question: What is the role of the visual fields in maintaining...

Determining the most effective exercise for gluteal muscle activation in children with Cerebral Palsy using surface electromyography
Publication date: Available online 15 March 2019Source: Gait & PostureAuthor(s): Colm Daly, Emer Lafferty, Marie Joyce, Ailish MaloneAbstractBackgroundReduced lumbo-pelvic postural control is a common feature of gait in children with Cerebral Palsy (CP). These features are commonly attributed to insufficiency of the hip musculature as well as underlying bony geometry. Exercises aimed at strengthening the hip muscles are frequently prescribed in children with Cerebral Palsy (CP). There is a lack...
