TLDR
New clinical assessment methods incorporating dual-task paradigms are helpful in revealing the effect of disease on the ability to allocate attention to postural tasks and appear to be sensitive measures in both predicting fall risk and in documenting recovery of stability.About:

Dual tasking, gait rhythmicity, and Parkinson's disease: which aspects of gait are attention demanding?
Galit Yogev,Nir Giladi,Nir Giladi,Chava Peretz,Chava Peretz,Shmuel Springer,Ely S. Simon,Jeffrey M. Hausdorff,Jeffrey M. Hausdorff,Jeffrey M. Hausdorff +9 more
TL;DR: It is demonstrated that regulation of gait variability and rhythmicity is apparently an automatic process that does not demand attention in healthy adults, however, in patients with PD this ability becomes attention‐demanding and worsens when subjects perform secondary tasks.

Dual‐tasking effects on gait variability: The role of aging, falls, and executive function

TL;DR: It is demonstrated that dual tasking does not affect the gait variability of elderly nonfallers or young adults, andDual tasking destabilizes the gact of idiopathic elderly fallers, an effect that appears to be mediated in part by a decline in EF.
Journal ArticleDOI
Assistive devices for balance and mobility: Benefits, demands, and adverse consequences
TL;DR: Clinical and biomechanic evaluations of canes and walkers confirm that these devices can improve balance and mobility, however, they can also interfere with ones ability to maintain balance in certain situations, and the strength and metabolic demands can be excessive.
Journal ArticleDOI
Dual-tasking postural control: Aging and the effects of cognitive demand in conjunction with focus of attention
TL;DR: A non-monotonic, U-shaped relation between the efficacy of postural control and concurrent cognitive demands that reflect opposing trends of the effects of attention focus and attentional resource competition is proposed and empirically examined.
Journal ArticleDOI
Gait dynamics in Parkinson’s disease: Common and distinct behavior among stride length, gait variability, and fractal-like scaling
TL;DR: This update highlights the idea that while stride length, gait variability, and fractal scaling of gait are all impaired in PD, distinct mechanisms likely contribute to and are responsible for the regulation of these disparate gait properties.

The Timed “Up & Go”: A Test of Basic Functional Mobility for Frail Elderly Persons
TL;DR: This study evaluated a modified, timed version of the “Get‐Up and Go” Test (Mathias et al, 1986) in 60 patients referred to a Geriatric Day Hospital and suggested that the timed “Up & Go’ test is a reliable and valid test for quantifying functional mobility that may also be useful in following clinical change over time.
Journal ArticleDOI
Predicting the probability for falls in community-dwelling older adults using the Timed Up & Go Test.
TL;DR: The TUG is a sensitive and specific measure for identifying community-dwelling adults who are at risk for falls and the ability to predict falls is not enhanced by adding a secondary task when performing the TUG.

Motor Control: Theory and Practical Applications
TL;DR: This text bridges the gap between research/theory and practice by focusing on the scientific and experimental basis of new motor control theories by specifically illustrating how recent findings and theories can be applied to clinical practice.
Journal ArticleDOI
"Stops walking when talking" as a predictor of falls in elderly people.
TL;DR: This investigation investigated the usefulness of the sign “stops walking when talking” in predicting falls and found that some frail elderly patients stop walking when they start a conversation with a walking companion, presumably because walking demands attention and they stop when they are expected to do two things at once.

The Effects of Two Types of Cognitive Tasks on Postural Stability in Older Adults With and Without a History of Falls
TL;DR: Results suggest that when postural stability is impaired, even relatively simple cognitive tasks can further impact balance and suggest that the allocation of attention during the performance of concurrent tasks is complex.
