Lower limb blood flow and mean arterial pressure during standing and seated work: Implications for workplace posture recommendations.

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.

A case study detailing key considerations for implementing a telehealth approach to office ergonomics.

Telehealth approaches to delivering ergonomics assessment hold great potential to improve service delivery in rural and remote settings. This case study describes a telehealth-based ergonomics service delivery process, and compares in-person and telehealth-based ergonomics approaches at an Alberta-based non-profit advocacy group. This project demonstrates that telehealth approaches to ergonomics do not lead to significantly different scoring outcomes for assessment of ergonomics issues, when compared to in-person assessments.

First steps for integrating sex and gender considerations into basic experimental biomedical research.

In recent decades there has been an increasing recognition of the need to account for sex and gender in biology and medicine, in order to develop a more comprehensive understanding of biological phenomena and to address gaps in medical knowledge that have arisen due to a generally masculine bias in research. We have noted that as basic experimental biomedical researchers, we face unique challenges to the incorporation of sex and gender in our work, and that these have remained largely unarticulated, misunderstood, and unaddressed in the literature. Here, we describe some of the specific challenges to the incorporation of sex and gender considerations in research involving cell cultures and laboratory animals.

Relationships between lower limb and trunk discomfort and vascular, muscular and kinetic outcomes during stationary standing work.

Standing work is associated with discomfort and symptoms in the trunk and lower limb. However, mechanisms underlying these observations are poorly understood. Moreover, most research on standing-related symptoms has focused on only one region (lower limb or trunk), and has not considered the impact and interactions between vascular, muscular and balance outcomes.

Gender effects on the coordination of subdivisions of the trapezius muscle during a repetitive box-folding task.

This study aimed at investigating gender difference in the coordination of the subdivisions of the trapezius muscle during a repetitive box-folding movement task. Twenty-two healthy volunteers (11 males and 11 females) performed the repetitive box-folding task for 34 min. During the task, perceived exertion and surface electromyographic (EMG) signals from the upper, middle, and lower trapezius subdivisions were recorded.

Understanding knowledge transfer in an ergonomics intervention at a poultry processing plant.

This case study reviews the knowledge transfer (KT) process of implementing a knife sharpening and steeling program into a poultry processing plant via a participatory ergonomics intervention. This ergonomics intervention required stakeholder participation at the company level to move a 'train-the-trainer' program, developed in Québec, Canada, into action on the plant's deboning line. Communications and exchanges with key stakeholders, as well as changes in steeling and production behaviours were recorded.
