Understanding the fundamental mechanisms governing fluctuating oscillations in large-scale
cortical circuits is a crucial prelude to a proper knowledge of their role in both adaptive and …

Sleep deprivation has a broad variety of effects on human performance and neural functioning
that manifest themselves at different levels of description. On a macroscopic level, sleep …

Objective. To explain and underscore the use of principal component analysis in clinical
biomechanics as an expedient, unbiased means for reducing high-dimensional data sets to a …

Objective: To address the problem of volume conduction and active reference electrodes in
the assessment of functional connectivity, we propose a novel measure to quantify phase …

In this study we examined changes in the large-scale structure of resting-state brain
networks in patients with Alzheimer's disease compared with non-demented controls, using …

Graph theory is a valuable framework to study the organization of functional and anatomical
connections in the brain. Its use for comparing network topologies, however, is not without …

In a recent study, De Haart et al. (Arch Phys Med Rehabil 85:886–895, 2004) investigated
the recovery of balance in stroke patients using traditional analyses of center-of-pressure (COP…

Low back pain (LBP) is often accompanied by changes in gait, such as a decreased (preferred)
walking velocity. Previous studies have shown that LBP diminishes the normal velocity-…

Background and objective. Spontaneous neurological recovery after stroke is a poorly
understood process. The aim of the present article was to test the proportional recovery model for …

We examined how people synchronize their leg movements while walking side-by-side on
a treadmill. Walker pairs were either instructed to synchronize their steps in in-phase or in …
