Fatigue can develop during prolonged computer work, particularly in elderly individuals. This study investigated eye movement characteristics relation to fatigue development. Twenty young and 18 healthy adults were recruited perform a functional task while their movements recorded. The lasted 40 minutes involving 240 cycles divided into 12 segments. Each cycle consisted of sequence memorization pattern, washout period, replication the pattern using mouse. participants rated perceived after...
The trial investigated the impact of a back-supporting exoskeleton (BSE) on biomechanics, work intensity, and musculoskeletal discomfort among logistic-workers over 24-weeks in field-setting. Twenty workers were randomized into intervention control groups, performing daily order-picking with without BSE, respectively. Effects muscles activity kinematics measured during standardized tasks before after period, while intensity rated throughout period. results indicated significant reductions...
The purpose of the study was to elucidate role expertise on muscle synergies involved in bench press. Ten expert power lifters ( EXP ) and nine untrained participants UNT completed three sets eight repetitions at 60% repetition maximum Muscle were extracted from surface electromyography data 21 press cycles using non‐negative matrix factorization algorithm. synergy activation coefficient represents relative contribution overall activity pattern, while vector weighting each within synergy....
This study aimed to investigate the neuromuscular control of knee during stair descent among female adolescents with patellofemoral pain (PFP) and report its association self-reported clinical status assessed by Knee Injury Osteoarthritis Outcome Score (KOOS).Fifty-seven previously untreated diagnosed PFP ages 15-19 yr were recruited from schools. The group consisted 29 age-matched healthy adolescents. Bipolar surface electrodes placed on vastus medialis lateralis, an electronic goniometer...
Increased movement variability has been suggested to reduce the risk of developing musculoskeletal disorders caused by repetitive work. This study investigated effects work pace on arm in a standardised pipetting task performed 35 healthy women. During at slow and fast paces differing 15%, movements arm, hand pipette were tracked 3D, used derive shoulder elbow joint angles. The size cycle-to-cycle motor was quantified using standard deviations several kinematics properties, while structure...
Nowadays the process of workstation design tends to include assessment steps in a virtual environment (VE) evaluate ergonomic features. These approaches are cost-effective and convenient since working directly on digital mock-up VE is preferable constructing real physical (RE). This study aimed at understanding ability VR-based assembly tasks simulator risk factors ergonomics. Sixteen subjects performed simplified RE VE. Motion upper body five muscle electromyographic activities were...
Construction work frequently involves heavy physical work, and a reduction of the workload should have high priority. Technological development has made it possible to obtain field measurements with surface electromyography (sEMG), kinematics measured inertial measurement units (IMUs), video recordings. However, no studies used these methods simultaneously detect situations excessive (events) during working day. Thus, knowledge about specific events may combat work-related risk factors....
The sensitivity of oculometrics to the changes in mental load has already been investigated several studies. However, reliability remains unexplored, particularly under concurrent demands. To address this, we recruited 20 young and 18 elderly healthy adults perform a functional computer task with three levels (i.e., low, medium, high) on two days interspaced by at least seven days. We tracked participants' eye movements pupil size during computed characterizing features saccades, fixations,...
Occupational exoskeletons contribute to diminish the biomechanical load during manual work. However, familiarization use of is rarely considered, which may lead failure acceptance and implementation. In this study, ten logistic workers underwent a 5-week progressive passive shoulder exoskeleton, while acted as controls. Tests pre post applied measurements muscle activity kinematics back, neck, shoulder, perceived effort, usability-ratings exoskeleton. Exoskeleton resulted in lower anterior...
We hypothesized changes in the spatial organization of trapezius muscle electromyographic (EMG) activity after a shoulder eccentric exercise. The rate perceived exertion (RPE), size soreness area, maximum force and, EMG from upper, middle and lower were recorded. Root mean square (RMS), frequency (MNF) normalized mutual information (a measure functional connectivity between sub‐divisions) computed during submaximal dynamic static contractions performed before, immediately 24 h Immediately...
AbstractThe aim of this cross-sectional study was to investigate the association between duration objectively measured forward bending trunk and low back pain (LBP) intensity among 198 Danish blue-collar workers (male = 115; female 83). The ≥ 30°, 60° 90° divided into high (the highest tertile) low–moderate remaining tertiles) categories. High (>5) ( ≤ 5) intensities were categorised from a self-reported 0–9 scale. Results multi-adjusted logistic regressions indicated no significant positive...

J Strength Cond Res 30(7): 1948–1959, 2016—The ability to perform forceful contractions has important implications in sports performance activities daily living. However, there is a lack knowledge adaptations intermuscular coordination after strength training. The purpose this study was therefore assess synergies before Thirty untrained...
The aim was to classify lifting activities into low and high risk categories (according Danish Working Environment Authority guidelines) based on surface electromyography (sEMG) trunk inclination (tri-axial accelerometer) measurements. Lifting tasks with different weights, horizontal distance technique were performed. characterised by a feature vector composed of either the 90th, 95th or 99th percentile sEMG activity level inclinations during task. Linear Discriminant Analysis...
There is high prevalence of back pain and neck-shoulder among blue collar workers in Denmark. Excessive physical exposures such as heavy lifting or working with bended twisted are risk factors for the construction industry. Technical evaluation awkward postures kinematics upper/ lower extremities (accelerometry) during work combined level muscular activity (EMG) video recordings can improve quantification exposure thereby facilitate designing preventive strategies. Participatory ergonomics...
Laptop work may increase risks of neck and back injuries in the long term due to awkward postures increased mechanical loads on cervical lumbar spine. This study was intended compare muscle activities postural changes as well discomfort resulted from laptop a conventional adjusted setup. 20 young healthy males performed two 8-min sessions computer-mouse typing setup an ergonomically during work. In setup, screen height individually by riser keyboard externally connected. The posture...
