Abstract:

The Grooved Pegboard Test, in its standard use, has well-documented utility. However, a revised methodology needs further study, leading us to investigate whether duration of eye fixation could predict performance on different task conditions of the Grooved Pegboard Test (place and remove pegs) with the preferred and nonpreferred hands. Fifty-two right-handed undergraduate students (33 male and 19 female), with a mean age of 22.22 (±3.57) years, performed the Grooved Pegboard Test. SensoMotoric eye-tracking glasses with a binocular time resolution of 30 Hz were used to measure eye fixation. Th

Abstract:

The purpose of the study was to evaluate the capacity of an expanded set of force steadiness tasks to explain the variance in the time it takes young men and women to complete the grooved pegboard test. In a single experimental session, 30 participants (mean ± SD) (24.2 ± 4.0 yr; 15 women) performed the grooved pegboard test, two tests of hand speed, measurements of muscle strength, and a set of submaximal, steady contractions. The steadiness tasks involved single and double actions requiring isometric contractions in the directions of wrist extension, a pinch between the index finger and thum

Abstract:

Abstract: There is limited knowledge of the neurocognitive effects of the serotonin precursor 5-hydroxytryptophan (5-HTP), which is sold over-the-counter as a nutritional supplement. Animal studies have demonstrated that exogenous 5-HTP promotes the production of ectopic serotonin in dopaminergic neurons—an effect that may reduce dopamine output in these cells. Behavioral studies in humans have demonstrated specific 5-HTP induced cognitive deficits on the Iowa Gambling Task and the Tower of London task that are likely the result of reduced forebrain dopamine. However, it remains unclear if 5-H

This study investigated the relation between tests of manual dexterity and attentional functions with 49 normal, right-handed medical students (26 women, 23 men, ages 19–30 years) who were assessed with a Purdue Pegboard Test, Grooved Pegboard Test, and a Test for Attentional Performance, comprising measures of tonic and phasic alertness and divided attention. Weak to moderately high partial correlations controlling for finger size were obtained between pegboard test performance of the left hand and phasic alertness ( r = .31–.5O).

Retest reliability was estimated for both measures. The Finger Tapping Test showed significant gender differences, since women were substantially slower, particularly in the older age groups. On the Grooved Pegboard Test, a converse gender difference was noted, since women were substantially faster than men. A smaller effect wi

This study investigated the influence of chronotype on motor behavior in a manual dexterity task performed at different times of the day. Sixteen healthy adults of each chronotype (morning, evening, and neither), as measured by the Morningness–Eveningness Questionnaire, practiced both conditions of the Grooved Pegboard Test either in the morning or in the afternoon to early evening. The “neither” chronotype (65.12 ± 7.46) was outperformed (ps ≤ .03) by both the morning (56.09 ± 7.21) and evening (58.94 ± 7.53) chronotypes when the task had higher cognitive and motor demand but was not outperfo

Abstract:

Abstract Frailty is a geriatric syndrome defined by coexistence of unintentional weight loss, low physical reserve, or activity and is associated with adverse health events. Neuroimaging studies reported structural white matter changes in frail patients. In the current study, we hypothesized that clinical frailty is associated also with functional changes in motion-related cortical areas, that is, (pre-)supplementary motor areas (SMA, pre-SMA). We expected that observed functional changes are related to motor-cognitive test performance. We studied a clinical sample of 143 cognitively healthy p

Abstract:

Fine motor and manual dexterity deficits are the main causes of significant physical and psychosocial impairments in stroke survivors. Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique used to modulate brain activity and improve clinical outcomes. This study was performed to investigate the efficacy of dual-hemispheric tDCS of the primary motor cortex (M1) in a patient with stroke exhibiting cortical sensation deficits. A double-blind, sham-controlled, single-case study was conducted. The patient underwent 30 sessions of sham tDCS followed by 30 real-s

Abstract:

Cognitive decline is associated with lifestyle-related factors such as overweight, blood pressure, and dietary composition. Studies have reported beneficial effects of dietary anthocyanins on cognition in older adults and children. However, the effect of anthocyanin-rich Aronia melanocarpa extract (AME) on cognition is unknown. Therefore, this study aimed to determine the effect of long-term supplementation with AME on cognitive performance, mood, and vascular function in healthy, middle-aged, overweight adults.

Abstract:

As the overall mortality declines following repair of complex congenital cardiac malformations, attention has focused on reducing the lasting morbidity of these interventions, particularly the observed neurodevelopmental deficiencies. Both cardiopulmonary bypass and deep hypothermic circulatory arrest produce transient alterations in cerebral hemodynamics and metabolism. In studies performed in animals, deep hypothermic circulatory arrest, as compared to cardiopulmonary bypass alone, has been shown to produce excess injury to, and death of, neuronal and glial cells.1 In neonates, deep hypother

Background: One of the fastest growing populations living with HIV is older adults especially those 65 years of age or older. Current antiretroviral therapy (ART) has prolonged life expectancy of persons with HIV. However, for therapy to be effective, patients need to be adherent. Over time, older persons with HIV may experience HIV-associated neurocognitive disorders or other factors that could affect ART adherence. The use of expedient cognitive tests that help measure medication adherence may be useful for the optimal care of these patients. Objective: To investigate the association between
