Reliability of Fatigue Measures in an Overhead Work Task: A Study of Shoulder Muscle Electromyography and Perceived Discomfort
… several EMG based parameters and subjective discomfort ratings through use of the Borg CR-10 scale. This study was part of a larger existing study that simulates overhead work in an automobile manufacturing plant. Ten participants used a drill tool to perform an overhead tapping task for one …

Understanding Underlying Risks and Socio-technical Challenges of Human-Wearable Robot Interaction in the Construction Industry
… measures such as muscle activity, productivity, perceived discomfort and exertion, usability, and stakeholders' perspectives. However, there is scarce evidence regarding the efficacy of using exoskeletons for construction work. Furthermore, the risks and sociotechnical challenges of employing …

Identification and Quantification of Workstation Set Up on Risk Factors Associated with the Development of Low Back and Neck Discomfort
… performance, back/neck electromyography (EMG), perceived discomfort, and number of posture shifts. Both monitor height and chair type were assessed using two levels (high and low). Participants, four male and four female college age students, performed two data entry tasks using a standard …

Effects of negatively sloped keyboard wedges on user performance and perceptions
… activity, wrist posture, key strike force, perceived discomfort, and performance to identify a negative keyboard angle or range of keyboard angles that minimizes exposure to hypothesized risk factors for hand/wrist work related musculoskeletal disorders. Ten experienced typists (4 males and …

The Effects of Job Rotation Parameters on Localized Muscle Fatigue and Performance: An Investigation of Rotation Frequency and Task Order
… including electromyography, and ratings of perceived discomfort. Performance was assessed through the accuracy of shoulder moment output, the accuracy of box placement, or the speed of assembly completion. As expected, rotation was effective in reducing fatigue compared to higher intensity …

Traditional Posterior Load Carriage: Ergonomic Assessment and Intervention Efficacy
… by reduced lumbosacral moment and ratings of perceived discomfort in several anatomical regions compared to the traditional PLC. Outcomes of this research can facilitate future ergonomic guidelines and interventions to improve working conditions and occupational health and safety for PLC …

Localized Muscle Fatigue: Theoretical and Practical Aspects in Occupational Environments
… development as reflected by rates of change in perceived discomfort, performance, and muscle capacity. Lastly, the dependency of muscle recovery on these different histories of fatiguing muscle contractions was explored. How a muscle recovers appeared to depend only on the state from which it …

The Influence of Multiple Risk Factors on WMSD Risk and Evaluation of Measurement Methods Used to Assess Risks
… muscle activity, heart rate, task performance, discomfort and workload ratings, and psychosocial environment perceptions. Social interaction should take priority over working in isolation, and pressure to achieve high performance should be minimized to reduce WMSD risk. A secondary data analysis …

Predicting Shoulder Fatigue for Long Durations Using Psychophysical Measures Obtained from Short Trials
… performing overhead work. Subjective (ratings of perceived discomfort) measures of fatigue were collected and their predictive potential was investigated. Effect of personality type was also examined to account for any inter-individual differences in fatigue perception. While researchers have …
