Relationship of demographic variables on perception of fatigue and discomfort following prolonged standing under various flooring conditions.

It has been suggested that prolonged standing is associated with pain and discomfort experienced by assembly line workers and other occupations. In an attempt to alleviate these problems, companies have implemented ergonomic interventions which include alterations to the flooring conditions upon which workers stand. The purpose of this study was to investigate assembly line workers' perceptions of fatigue and discomfort associated with various body regions after standing for an 8-h shift on three different flooring conditions: (1) standing on a wood-block floor, (2) standing on a floor mat, and (3) wearing insoles.
