Assessing a Sensory-Motor-Cognition Triad in Amnestic Mild Cognitive Impairment With Dichotic Listening While Walking: A Dual-Task Paradigm
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-12)A contemporary topic in aging research relates to the significance of cognitive changes proper to mild cognitive impairment (MCI) to higher risk of falls and gait deteriorations. The present study addresses this question in the amnestic type of MCI (aMCI) by examining a triad of interrelated comorbidities occurring in the MCI condition: attentional impairments, hearing loss and gait disturbances. ... -

Dichotic listening while walking: A dual-task paradigm examining gait asymmetries in healthy older and younger adults
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-08)Dual-task studies have employed various cognitive tasks to evaluate the relationship between gait and cognition. Most of these tests are not specific to a single cognitive ability or sensory modality and have limited ecological validity. In this study, we employed a dual-task paradigm using Dichotic Listening (DL) as concomitant cognitive task to walking. We argue that DL is a robust task to unravel ... -
Effects of anodal transcranial direct current stimulation on experimentally induced heat pain in healthy volunteers
(Master thesis; Mastergradsoppgave, 2012-05-02)Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulatory technique that can reduce pain. Its side effects are milder than those of pharmacological treatments, and its analgesic effect on chronic pain has been demonstrated. In this study we investigated 1) the effects of anodal tDCS on pain intensity and threshold, 2) the placebo component of tDCS analgesic effect, and 3) ... -
Effects of dichotic listening on gait domains of healthy older adults during dual-tasking: An exploratory observational study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-28)<i>Background</i> - Identification of the cognitive mechanisms behind gait changes in aging is a prime endeavor in gerontology and geriatrics. For this reason, we have implemented a new dual-task paradigm where an auditory attentional task is performed during over-ground walking. Dichotic listening assesses spontaneous attention and voluntary attention directed to right and left-ear. The uniqueness ... -
The impact of age-related hearing loss and lateralized auditory attention on spatiotemporal parameters of gait during dual-tasking among community dwelling older adults
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-27)This investigation assessed the impact of hearing loss and lateralized auditory attention on spatiotemporal parameters of gait during overground dual-tasking by the use of the dichotic listening task. Seventy-eight right-handed, healthy older adults between 60 and 88 years were assigned to a Young-Old (<70 years) or an Old-Old (>71 years) group. Cognitive assessment and pure tone audiometry were ... -
Manual dexterity in young and healthy older adults. 1. Age- and gender-related differences in unimanual and bimanual performance
(Journal article; Tidsskriftartikkel, 2018-03-12)This study aimed to better characterize age‐related differences in dexterity by using an integrative approach where movement times and kinematics were measured for both hands. Forty‐five young (age 19–31) and 55 healthy older adults (age 60–88) were evaluated during unimanual and bimanual performance of the Purdue Pegboard Test. Gender effects were also assessed. From video‐recorded data, movement ... -
Manual dexterity in young and healthy older adults. 2. Association with cognitive abilities
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-02)Currently, little is known about the cognitive constraints underlying manual dexterity decline in aging. Here, we assessed the relationship between cognitive function and dexterity in 45 young and 55 healthy older adults. Effects of gender on the cognition‐dexterity association were also explored. Cognitive assessment comprised neuropsychological tests of executive function, working memory, attention, ... -
Reduction in manual asymmetry and decline in fine manual dexterity in right-handed older adults with mild cognitive impairment
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-16)Research in Parkinson’s or Alzheimer’s disease suggests that hand function is affected by neurodegenerative diseases. However, little is known about the relationship between hand function and mild cognitive impairment (MCI). Therefore, we conducted a kinematic analysis of unimanual hand movements in MCI patients to answer whether manual asymmetries and manual dexterity are affected or preserved ... -
White matter correlates of gait perturbations resulting from spontaneous and lateralized attention in healthy older adults: A dual-task study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-18)To date the neural mechanisms behind gait perturbations caused by dual-task paradigms are still unknown. Therefore, the present study examined white matter correlates of gait perturbations caused by a dichotic listening task where spontaneous (free focus of attention) and lateralized attentional control (voluntary attention directed to right or left-ear) were tested. Fifty-nine right-handed, healthy ...
