Importance Patients with Parkinson disease can use a wide variety of strategies to
compensate for their gait impairments. Examples include walking while rhythmically …

Akinesia is a major manifestation of Parkinson's disease (PD) related to difficulties or failures
of willed movement to occur. Akinesia is still poorly understood and is not fully alleviated by …

Although characteristic motor symptoms of Parkinson's disease such as bradykinesia
typically improve under dopaminergic medication, deficits in higher motor control are less …

Older individuals typically display stronger regional brain activity than younger subjects
during motor performance. However, knowledge regarding age-related changes of motor …

Movements result from a complex interplay of multiple brain regions. These regions are
assembled into distinct functional networks depending on the specific properties of the …

Patients with Parkinson's disease (PD) often have difficulties generating rhythmic
movements, and also difficulties on movement adjustments to accuracy constraints. In the …

Dopaminergic medication is widely used to alleviate motor symptoms of Parkinson's
disease, but these medications also impact cognition with significant variability across …

Many studies have used functional magnetic resonance imaging to unravel the neuronal
underpinnings of motor system abnormalities in Parkinson's disease, indicating functional …

A consistent finding in motor EEG research is a bilateral attenuation of oscillatory activity
over sensorimotor regions close to the onset of an upcoming unilateral hand movement. In …

People with Parkinson's disease (PD) show impaired decision-making when sensory and
memory information must be combined. This recently identified impairment results from an …
