BACKGROUND: Parkinson's disease (PD) impairs control of well-learned movements. Movement control improvements are found when individuals complete tasks while focusing attention externally on manipulating an object, which is argued to occur due to automatic processing associated with well-learned movements. Focusing attention internally (on movements of ones' limbs) is believed to involve conscious control networks, and hinders movement performance. Previous work has found that an external focus of attention improved postural stability in individuals with PD (compared to internal), but this was when patients were taking dopamine medication, which modulates basal ganglia functioning responsible for well-learned movements...

The lack of sleep, both in quality and quantity, is an increasing problem in modern society, often related to workload and stress. A number of studies have addressed the effects of acute (total) sleep deprivation on postural control. However, up to date, the effects of chronic sleep deficits, either in quantity or quality, have not been analyzed. Thirty healthy adults participated in the study that consisted of registering activity with a wrist actigraph for more than a week before performing a series of postural control tests...

BACKGROUND: The application of Kinesio Tex® tape (KT) results, in theory, in the improvement of muscle contractibility by supporting weakened muscles. The effect of KT on muscle strength has been investigated by numerous researchers who have theorized that KT facilitates an immediate increase in muscle strength by generating a concentric pull on the fascia. The effect of KT on balance and functional performance has been controversial because of the inconsistencies of tension and direction of pull required during application of KT and whether its use on healthy individuals provides therapeutic benefits...
