The present study investigated the effect of time of day (08h00 vs. 11h00 vs. 14h00 vs. 17h00) and sex (girls vs. boys) on physical (i.e., five jump test (5JT), push-ball test and 5 m shuttle run test...
Thirty schoolchildren, equally divided in girls (n = 15; age: 9.60 ± 0.51 years) and boys (n = 15; age: 9.40 ± 0.51 years) performed the digit cancellation test, the trail making test, the 5JT, the 2 ...
Results showed that RPE at the end of the test was significantly higher at 11h00 compared to 08h00 (p = 0.02) and 14h00 (p = 0.001) and average RPE was higher at 11h00 compared to 08h00 (p = 0.001). L...
Mental flexibility, attention and jump performances were time of day dependent and push-ball test and 5mSRT performances did not change according to the time of day. Also, no clear sex effect was foun...
Chronic excessive welding exposure may be related to higher metal accumulation and structural differences in different subcortical structures. We examined how welding affected brain structures and the...
Study includes 42 welders and 31 controls without a welding history. Welding-related structural differences were assessed by volume and diffusion tensor imaging (DTI) metrics in basal ganglia, red nuc...
Compared to controls, welders displayed higher hippocampal mean (MD), axial (AD), and radial diffusivity (RD) (p's < 0.036), but similar DTI or volume in other ROIs (p's > 0.117). Welders had higher b...
Welding-related higher hippocampal diffusivity metrics may be associated with higher RN R2* and lower psychomotor speed performance. Future studies are warranted to test the role of Pb exposure in the...
Co-use of alcohol and cannabis is associated with increased frequency and intensity of use and related problems. This study examined acute effects of alcohol and cannabis on mood, subjective experienc...
Alcohol-induced driving impairment can occur with any departure from a zero-blood alcohol concentration (BAC). Because intoxication is characterised by impaired judgement, drivers under the influence ...
This study examined the effects of alcohol on driving performance, four-choice reaction time (FCRT), and self-rated confidence in driving ability. It specifically focused on alcohol doses equal to com...
A randomized, double-blind, placebo-controlled design was utilised. Seventeen participants were tested in three conditions: placebo and two alcohol conditions aiming for BACs of 0.05% and 0.08%. Parti...
The high and low alcohol dose conditions resulted in a mean BAC of 0.07%, and 0.04%, respectively (n = 17). The high BAC treatment significantly increased standard deviation of lateral position (SDLP)...
The findings of this study show that driving performance and associated psychomotor functioning become significantly impaired below legally permissible driving limits in some jurisdictions. We identif...
Psychomotor skills, a cognitive and fine motor process, are an essential component to undergraduate nursing education. Currently, no national guidelines exist to guide nursing programs on the best way...
An integrative review was conducted to determine teaching and practice strategies to support psychomotor skill competence....
Four significant categories were identified and included (1) simulation; (2) technology; (3) deliberate practice; and (4) theoretical and collaborative instruction. Overall, simulation and technology ...
Additional research is needed to identify which teaching strategies best support nursing students' long-term knowledge acquisition and competency as they transition into professional practice....
Robotic surgery is a rapidly expanding field, given the wide variety of new robotic platforms emerging. Looking at the training of surgeons in robotic surgery is of extreme necessity and urgency, cons...
Patients with severe drug-resistant epilepsy (DRE) experience psychomotor disorders. Our study aimed to assess the psychomotor outcomes after vagus nerve stimulation (VNS) in this population....
We prospectively evaluated psychomotor function in 17 adult patients with severe DRE who were referred for VNS. Psychomotor functions were examined, in the preoperative period and at 18 months post-su...
At 18 months post-VNS surgery, the Piaget-head scores increased by 3 points (p = 0.008) compared to baseline. Performances were also improved for ROCF test both in copy (+2.4 points, p = 0.001) and re...
Patients with severe DRE treated with VNS experienced improved performance in terms of global psychomotor functions. Perceptual organization, visuospatial memory, laterality awareness, sustained atten...
This study examined the effects of work-related electronic communication (WREC) during non-working hours in the work from home or office setting on health....
The study recruited 98 information technology workers in a 9-day observational study. They recorded work-life events (eg, work style (working mostly from home or the office) and duration of WREC durin...
The frequency of WREC was significantly higher when working mostly from home than in the office (p<0.01). In addition, the duration of WREC was longer when working mostly from home than in the office ...
Longer WREC is associated with worse fatigue and depression and lower lapse of PVT (higher alertness) before bedtime for working mostly from the office. Workers, especially those working from the offi...
Despite being added to numerous products, little is known about cannabidiol. Drowsiness is a self-reported side effect, which could impact cognitive functioning. To determine whether cannabidiol impac...
Sustained exposure to acetaldehyde, the major metabolite of ethanol, may influence psychomotor performance even after the breath ethanol level significantly drops several hours following ethanol consu...
