It is known that sit/stand desks improve physical activity and energy expenditure and improve discomfort by allowing the ability to change postures. The goal of this feasibility pilot study is to determine the appropriate sit/stand dosage for height adjustable workstations. It is hypothesized that weight shifting during sitting and standing office work can be used as an objective measure to inform personalized best practice of sit/stand workstation use. Objective and subjective measures of discomfort or fatigue will be obtained and compared to measures of weight shifting during both sitting and standing. This data will be used as the starting point for determining dosage recommendations and for the development of a worker-centered dosage delivery device that will be further tested for utility and effectiveness in the future.
