Levodopa pharmacokinetics and motor performance during activities of daily living in patients with Parkinsons disease on individual drug combinations.

Pharmacokinetics and pharmacodynamics of levodopa were evaluated at a high-resolution level in a heterogeneous group of 10 patients with idiopathic Parkinsons disease during their normal daily activity. A physician and a nurse spent 10 hours with each ...

Motor response to apomorphine in patients with Parkinsons disease with long-duration response to levodopa.

The authors studied the motor response to apomorphine before and 1 year after levodopa therapy in 12 patients with Parkinsons disease. At the 1-year evaluation, the basal tapping score, recorded after a 12-hour levodopa withdrawal, was higher compared ...

Coincidence timing of a tennis stroke: effects of age, skill level, gender, stimulus velocity, and attention demand.

Participants (N = 162, ages 10-15 years) performed a tennis stroke in a coincidence-timing task. Major results were: (a) performance improved mainly between the ages of 10-13 years; (b) skill differences were reflected by variable error (VE); (c) boys ...

Trunk movement in Parkinsons disease during rising from seated position.

Parkinsons disease (PD) is associated with particular difficulties rising from a seated position. Little is known about the mechanisms of sit-to-stand in this condition. We sought to define trunk movement during sit-to-stand in a group of patients with ...

Is essential tremor predominantly a kinetic or a postural tremor? A clinical and electrophysiological study.

Both postural and kinetic tremors may occur in essential tremor (ET), however the relative contribution of each is not clear. ET has been variably defined with respect to kinetic and postural tremors. To examine the relative severity of postural and ...

Differences in white matter architecture between musicians and non-musicians: a diffusion tensor imaging study.

Previous studies found structural brain differences between musicians and non-musicians. In order to determine possible differences in white matter architecture, diffusion tensor imaging was performed on five adult subjects with musical training since ...

Implications of child development on the practice of oral care.

Of all patient groups, children represent perhaps the most challenging in the preventive dental practice. While technical skills must be excellent, the interpersonal skills of the clinician are also paramount to successful pediatric dentistry and are ...

Relationship between skill and outcome in the laboratory-based model.

BACKGROUND: Recent attention has been directed at developing quantitative assessments of surgical skill. This study aims to demonstrate whether objectively measuring differences in manual dexterity has an impact on a simulated surgical procedure. ...

Old age impairs the use of arbitrary visual cues for predictive control of fingertip forces during grasp.

Old age impairs the ability to form new associations for declarative memory, but the ability to acquire and retain procedural memories remains relatively intact. Thus, it is unclear whether old age affects the ability to learn the visuomotor associations ...

Dexterity is not affected by fatigue-induced depression of human motor cortex excitability.

Following a fatiguing muscle contraction, motor evoked potentials (MEPs) evoked by transcranial magnetic brain stimulation remain depressed for many minutes, reflecting a reduction in the excitability of the corticospinal projection. No functional ...
