Abstract: BACKGROUND: The use of wearable accelerometers in conjunction with Functional Capacity Evaluation (FCE) may provide additional useful information about maximum performance in workers and enhance the validity of functional testing. However, little research has been conducted to compare accelerometer output with performance during FCE. OBJECTIVE: The objectives of this study were to: (1) Determine the magnitude and direction of correlation between participant performance on five FCE tasks and scores from Actigraph activity monitors; and (2) Compare the results of two different placements of Actigraph devices. METHOD: We used a cross-sectional design and convenience sampling to collect …data from 46 healthy participants. Each participant completed 5 functional tasks selected from the WorkWell FCE protocol while wearing 2 Actigraph devices, 1 on the dominant side waist and 1 on the non-dominant wrist. The FCE tasks included 5-repetition maximum lifting (floor-to-waist, waist to crown and front carry), a sustained overhead work endurance task, and the 6-minute walk test. Analysis included calculating Pearson regression coefficients between maximum FCE item performance and Actigraph vector magnitudes (VM) along with Intraclass Correlation Coefficients (ICC) to compare VM activity counts derived from the Actigraphs on the waist and wrist. RESULTS: Thirty-Nine (84.8%) participants had complete data and were included in analysis. Findings indicate Actigraph VM data from the device worn on the waist correlated positively with maximum lift performance (r = 0.39–0.64, p < 0.001 to 0.08) and 6-minute walk distance (r = 0.66, p < 0.001). Actigraph data from wrist placement were not significantly correlated with FCE performance on any of the functional tasks, except when comparing average VM data and waist to crown lift (r = 0.44, p < 0.001). There was no significant correlation in either Actigraph placement for VM and overhead work time. ICCs between the two Actigraph placements ranged from poor to acceptable agreement (ICC = 0.24–0.70, p < 0.001 to 0.19). CONCLUSIONS: Actigraph device output correlated moderately with maximum performance on FCE lift and ambulation tests. Waist placement appears more suitable than wrist during performance-based tests.

Abstract: INTRODUCTION: Many adverse effects occur among the nurses due to shift work Hence, the present study aimed to determine the prevalence of shift work-related disorders and its related factor among the nurses at Tehran University Subsidiary Hospital, Iran, and to find solutions for managing the relevant health problems. METHODS: In this cross-sectional study, the Survey of Shift workers (SOS) questionnaire and the Personal Information Form were used to collect data related to demographics and working conditions of 1259 randomly selected nurses working at Tehran University Subsidiary Hospital as statistical population. RESULTS: According to the results, psychological …disorders (95%), digestive problems (85%) and social problems (80%) were the most frequent problems among the subjects. Additionally, the satisfaction rate was higher among the volunteer nurses compared to nurses who were forced to do shift work (P < 0.05). CONCLUSION: The nurses volunteered for shift work had higher satisfaction rate compared to nurses forced to shift work system; moreover, they had more job satisfaction and less shift work-related complaints. Therefore, it is important to select the nurses who are volunteer for shift work system. In addition, the shift work schedule in hospitals should be set based on workload and requirements because the shift schedule can adversely influence the social and family issues of the nurses, as well as their sleep quality and body biological process.

Abstract: BACKGROUND: Research suggests that one-third of Norwegian adults satisfy national health recommendations for physical activity, but little knowledge exists regarding activity levels in different occupations. OBJECTIVES: This study investigates the level at which kindergarten staff fulfil these health recommendations, and examines differences in physical activity levels of staff working mainly with toddlers (1–3 years) and older children (4–6 years). The study also investigates physical activity level during working time and leisure time. METHODS: Physical activity levels among 43 kindergarten staff members were measured utilizing accelerometers and questionnaires. RESULTS: The results demonstrate that 86% of …kindergarten staff satisfy the health recommendations for physical activity. Moreover, kindergarten staff working with older children were significantly more physically active than staff working with toddlers. CONCLUSIONS: Physical activity level during working time was found to be of major significance for fulfilling the health recommendations among kindergarten staff working with toddlers. Show more

Abstract: BACKGROUND: Several risk factors among packing lines workers can lead to Work-related Musculoskeletal Disorders (WRMSD) occurrence. Foreseeing WRMSD prevention and productivity increase, some furniture manufacturing industries have been investing in the adoption of robotic solutions. In this field, ergonomics plays an important role to verify if automation implementation has been successful. OBJECTIVE: This study aims to address the general impact and effectiveness from an ergonomics point of view of the implementation of a robotic aid in a packing workstation. METHODS: The Nordic Musculoskeletal Questionnaire (NMQ) was applied to 14 workers of semi-automated packing lines. Some additional …questions about occupational conditions were included. In order to assess the ergonomic impact of the robotic aid, Rapid Upper Limb Assessment (RULA) was also applied by trained ergonomists, by analyzing the considered packing workstations before and after the adoption of the robotic aid proposed solution. RESULTS: The results showed that trunk torsion was the most highlighted WRMSD risk factor by all workers, associating it with the lumbar pain. The obtained RULA scores demonstrated that the adoption of a robotic aid eliminated this risk factor and, consequently, reduced the corresponding WRMSD risk. CONCLUSIONS: The adoption of robotic aids can be instrumental in reducing WRMSD risk in furniture manufacturing industries. Ergonomic studies with workers’ participatory approaches seem to be an appropriate strategy to enable the validation and development of industrial robotic solutions. Show more
