Endogenous biological clocks, orchestrated by the suprachiasmatic nucleus, time the
circadian rhythms that synchronize physiological and behavioural functions in humans. The …

Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor
impairments such as tremor, bradykinesia, dyskinesia, and gait abnormalities. Current …

An ambulatory system for quantification of tremor and bradykinesia in patients with
Parkinson's disease (PD) is presented. To record movements of the upper extremities, a …

Sleep has been described as being of the brain, by the brain, and for the brain. This
fundamental neurobiological behavior is controlled by homeostatic and circadian (24-hour) …

The objective was to design, build, and assess Kinesia™, a wireless system for automated
assessment of Parkinson's disease (PD) tremor. The current standard in evaluating PD is the …

Measurement of human posture and movement is an important area of research in the
bioengineering and rehabilitation fields. Various attempts have been initiated for different …

A new ambulatory method of monitoring physical activities in Parkinson's disease (PD)
patients is proposed based on a portable data-logger with three body-fixed inertial sensors …

BACKGROUND: Timely detection of early cognitive impairment is difficult. Measures taken in
the clinic reflect a single snapshot of performance that might be confounded by the …

In this paper, we examine at-home activity rhythms and present a dozen of behavioral
patterns obtained from an activity monitoring pilot study of 22 residents in an assisted living …

Background Disturbance of sleep is common in individuals with dementia where there may
be reversal of the sleep‐wake cycle. People with dementia of the Alzheimer's type have …
