Using Virtual Reality to Distract Overweight Children from Bodily Sensations During Exercise
2016
This study analyzes the potential of virtual reality (VR) to enhance attentional distraction in overweight children as they experience bodily sensations during exercise. It has been suggested that one reason why obese children stop exercising is the perception of bodily sensations. In a counterbalanced design, a total of 109 children (33 overweight, 10-15 years old) were asked to walk twice for 6 minutes on a treadmill under one of two conditions: (a) traditional condition (TC)-focusing their attention on their physical feelings and sensations or (b) distraction condition (DC)-focusing their attention on a virtual environment. Attentional focus during exercise, bad-good feeling states (pre-…
The reliability of continuous brain responses during naturalistic listening to music
2015
Low-level (timbral) and high-level (tonal and rhythmical) musical features during continuous listening to music, studied by functional magnetic resonance imaging (fMRI), have been shown to elicit large-scale responses in cognitive, motor, and limbic brain networks. Using a similar methodological approach and a similar group of participants, we aimed to study the replicability of previous findings. Participants' fMRI responses during continuous listening of a tango Nuevo piece were correlated voxelwise against the time series of a set of perceptually validated musical features computationally extracted from the music. The replicability of previous results and the present study was assessed b…
The role of attachment dimensions and perceived social support in predicting adjustment to cancer.
2009
Objective: Several studies carried out over the last years show that patients' adjustment is very important to the past experiences of people with cancer. In our study of 96 subjects with cancer, we examined whether patient's working model of attachment anxiety/avoidance and perceptions of social support predicts adjustment to cancer. Methods: All participants filled in a demographic questionnaire, the Relationship Scale Questionnaire (RSQ), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Mental Adjustment to Cancer (MAC). Results: Anxious attachment predicted psychological adjustment: patients with high levels of anxious attachment showed high levels of helplessness…
Integration of an in-home monitoring system into home care nurses' workflow: A case study.
2019
Abstract Background The healthcare system faces a major challenge in caring for an increasingly ageing population as this task requires more resources than are currently available. Adopting monitoring technologies could enable more efficient care practices and support ageing in place. Objectives To investigate how the use of an in-home motion monitoring system can be integrated into home care nurses’ workflows and to uncover the factors behind system adoption. Design A single case study adopting a qualitative approach. Setting A home care unit serving older adults living in independent living residences within an apartment complex. Method Multiple data collection methods were used including…
The chronnectome of musical beat
2020
Keeping time is fundamental for our everyday existence. Various isochronous activities, such as locomotion, require us to use internal timekeeping. This phenomenon comes into play also in other human pursuits such as dance and music. When listening to music, we spontaneously perceive and predict its beat. The process of beat perception comprises both beat inference and beat maintenance, their relative importance depending on the salience of beat in the music. To study functional connectivity associated with these processes in a naturalistic situation, we used functional magnetic resonance imaging to measure brain responses of participants while they were listening to a piece of music contai…
The role of pregnenolone sulphate in spatial orientation-acquisition and retention: An interplay between cognitive potentiation and mood regulation
2013
Abstract Neurosteroids can alter neuronal excitability interacting with specific neurotransmitter receptors, thus affecting several functions such as cognition and emotionality. In this study, we investigated, in adult male rats, the effects of the acute administration of pregnenolone-sulfate (PREGS) (10 mg/Kg, s. c.) on cognitive processes using the Can test, a non aversive spatial/visual task which allows the assessment of spatial information-acquisition during the baseline training, and of memory retention in the longitudinal study. Furthermore, on the basis of PREGS pharmacological profile, the modulation of depressive-like behaviour was also evaluated in the forced swim test (FST). Our…
Immediate effects of active versus passive scapular correction on pain and pressure pain threshold in patients with chronic neck pain.
2012
OBJECTIVE: The purpose of this study was to investigate the effect of active vs passive scapular correction on pain and pressure pain threshold at the most symptomatic cervical segment in patients with chronic neck pain. METHODS: Twenty-three volunteers with chronic, idiopathic neck pain were recruited (age, 38.9 ± 14.4 years; sex [man/woman], 3/20; Neck Disability Index, 28.1% ± 9.9%). Subjects were randomly allocated to 2 groups: active scapular correction or passive scapular correction. Pressure pain threshold and pain intensity rated on a numerical rating scale during a posteroanterior glide over the most symptomatic cervical segment were measured before and immediately after the active…
Differential dopamine receptor D4 allele association with ADHD dependent of proband season of birth
2008
Contains fulltext : 70196.pdf (Publisher’s version ) (Closed access) Season of birth (SOB) has been associated with attention deficit hyperactivity disorder (ADHD) in two existing studies. One further study reported an interaction between SOB and genotypes of the dopamine D4 receptor (DRD4) gene. It is important that these findings are further investigated to confirm or refute the findings. In this study, we investigated the SOB association with ADHD in four independent samples collected for molecular genetic studies of ADHD and found a small but significant increase in summer births compared to a large population control dataset. We also observed a significant association with the 7-repeat…
Genome-wide association study of motor coordination problems in ADHD identifies genes for brain and muscle function.
2012
Item does not contain fulltext OBJECTIVES: Motor coordination problems are frequent in children with attention deficit/hyperactivity disorder (ADHD). We performed a genome-wide association study to identify genes contributing to motor coordination problems, hypothesizing that the presence of such problems in children with ADHD may identify a sample of reduced genetic heterogeneity. METHODS: Children with ADHD from the International Multicentre ADHD Genetic (IMAGE) study were evaluated with the Parental Account of Children's Symptoms. Genetic association testing was performed in PLINK on 890 probands with genome-wide genotyping data. Bioinformatics enrichment-analysis was performed on highly…
Sex Differences in Feedback: Effects on Rod-and-Frame Performance
1979
It has been demonstrated that feedback is effective in changing rod-and-frame performance for women if given the opportunity to adjust the rod to the vertical repeatedly from the same starting position. It is also shown that the significant difference between males and females in the Rod-and-frame Test is carried by the large difference in the initial tilting position.
