“…Venous edema increased in the evening and was more pronounced in individuals with evidence of varicose veins. Ngomo, Messing, Perrault, and Comtois (2008) measured the effect of prolonged standing on self-reported orthostatic symptoms, heart rate, and blood pressure in workers who stand for significant periods of time during their workday (i.e., average of 84-95% of the workday) and reported blood pressure changes. Sudoł-Szopi nska, Panorska, Kozi nski, and Błachowiak (2007) conducted a prospective study examining differences in risk of chronic venous disorders for workers who are exposed to prolonged standing compared with workers who primarily are exposed to prolonged sitting in the workplace.…”

Purpose Prolonged standing at work has been shown to be associated with a number of potentially serious health outcomes, such as lower back and leg pain, cardiovascular problems, fatigue, discomfort, and pregnancy related health outcomes. Recent studies have been conducted examining the relationship between these health outcomes and the amount of time spent standing while on the job. The purpose of this article was to provide a review of the health risks and interventions for workers and employers that are involved in occupations requiring prolonged standing. A brief review of recommendations by governmental and professional organizations for hours of prolonged standing is also included. Findings Based on our review of the literature, there seems to be ample evidence showing that prolonged standing at work leads to adverse health outcomes. Review of the literature also supports the conclusion that certain interventions are effective in reducing the hazards associated with prolonged standing. Suggested interventions include the use of floor mats, sit-stand workstations/chairs, shoes, shoe inserts and hosiery or stockings. Studies could be improved by using more precise definitions of prolonged standing (e.g., duration, movement restrictions, and type of work), better measurement of the health outcomes and more rigorous study protocols. Conclusion and Clinical Relevance Use of interventions and following suggested guidelines on hours of standing from governmental and professional organizations should reduce the health risks from prolonged standing.

“…However, these changes in lower limb blood pressure were not tracked during work tasks. Earlier work tracking brachial blood pressure changes during standing occupations did note a reduction in MAP in the upper limb ( Ngomo et al, 2008 ), but such benefits may be offset if there are increases in MAP in the lower limb. In addition to increases in arterial pressure in the lower limb, we must also consider venous back flow and pooling in the lower limb due to gravity during standing work.…”

Sit-stand workstations are a popular workplace intervention. Organizations often require a medical professional's guidance for implementation. Therefore, it is important to understand potential negative outcomes associated with standing work, such as lower limb discomfort and peripheral vascular issues. The objective of this study was to compare changes in lower limb discomfort, blood pressure and blood flow accumulation during a light-load repetitive upper limb work task accomplished from seated and standing postures. At the Jewish Rehabilitation Hospital (Laval, Quebec, Canada), 16 participants were outfitted with Laser Doppler Flow (LDF) electrodes to measure blood flow in the lower limb, and a sphygmomanometer to measure lower limb mean arterial blood pressure (MAP). Participants completed simulated work over 34 min in standing and seated conditions. Repeated measures ANOVAs (Posture x Time) were used to assess the differences. There were significant effects for both Posture (p = 0.003) and Time (p = 0.007) for LDF-measured of blood flow accumulation in the soleus and the foot, with a mean increase of 77% blood flow over time in the standing posture, when compared to seated work. There was a significant ‘Posture × Time’ (p = 0.0034) interaction effect and a significant Posture (p = 0.0001) effect for MAP, with higher values in the standing posture by a mean of 37.2 mmHg. Posture had a significant effect (p < 0.001) on lower limb discomfort, with standing posture reporting higher levels. These results suggest that recommendations for using static standing work postures should be tempered, and physicians' guidance on workstation changes should consider the impacts on the lower limb.

“…One of the key objectives of researchers and practitioners dealing with WMSD is to identify factors that contribute to their development and associated disability. Members of our team have contributed to the literature demonstrating that physical workload as well as organizational and psychological work-related factors all play parts in the development of WMSDs (Delisle et al, 2006;Fuller, Fung and Côté, 2011;Laperrière et al, 2006;Ngomo et al, 2008;St-Vincent et al, 2006). However, the inter-relationships between these risk factors and the causal pathways to the associated outcomes are not well understood, so effective prevention may necessitate the use of more complex analytic tools (Aschengrau and Seage, 2003).…”

“…For instance, tendon disorders of the lower extremities are relatively common but have rarely been studied (Burdorf, Naaktgeboren and De Groot, 1993;Janwantanakul et al, 2010;Kalra et al, 2010;Kennedy et al, 2010). Several group members study determinants and effects of prolonged standing at work (Messing, Tissot and Stock, 2008), in the hope of producing suggestions for an optimal mix of working postures between standing, sitting and walking (Laperrière et al, 2006;Ngomo et al, 2008). It appears that worker control over posture is an important health determinant (Messing, Tissot and Stock, 2008).…”

This paper aimed to demonstrate the contribution of the research performed by the musculoskeletal disorders (MSD) Research Axis group of the Quebec Occupational Health and Safety Research Network towards better understanding of work-related MSD (WMSD) development and prevention. Although the group targets its work to the Quebec population, its work has significant impact around the world, placing MSD axis members and knowledge and expertise created in Quebec on the international map. Results from the contribution of members are relevant, primarily in the demonstration of the implication of physical workload as well as organizational and psychosocial work-related factors in the development of WMSDs. Also, members have demonstrated that gender, sex, social class, age and ethno-cultural groups interact in various ways with WMSD determinants. Efforts are devoted towards improving understanding of the physiological responses linked with MSDs, which could also lead to new workplace practices in rehabilitation. The group emphasizes the integration of prevention procedures from the design stage to the workplace intervention. Members have proposed research-based tools for best practices at work and also an original conceptual model as a key, novel element of a theoretical conceptualization of WMSDs. Moreover, the group focuses on improving WMSD surveillance, using multiple sources of information, providing information on newly identified health risks and developing new methods of assessing risk in order to effectively prevent disability in the working population. Finally, results from research of the MSD axis group have implications for orienting legal processes, improving legal recognition of MSDs as occupational diseases, and contributing to the evolution of legal thinking. However, much remains to be done. To that end, the group plans and encourages new initiatives for further advancement. In conclusion, the originality of the work places the group in a favourable position to address the complexity underlying WMSDs, combining expertise that enriches fundamental, clinical and population-based research.
