Lateral acceleration causes discomfort but how the discomfort depends on the frequency of acceleration or characteristics of seating is poorly understood. Using magnitude estimation, twelve male subjects rated the discomfort caused by lateral oscillation at eight frequencies (0.2-1.0 Hz) across four seating conditions (a rigid seat and a train seat, both with and without backrests). Discomfort ...

A classification of seating postures is necessary for a systemic approach in chair ergonomics. The methodology used criteria differentiating and grouping variants into categories. Morphological (hip flexion, trunk inclination, lumbar lordosis, muscular involvement), functional (the relationship with working areas), cultural (conventional unconventional) were brought discussion arguments validat...

SUMMARY For 30 years or so specialists in wheelchair seating services in the developed world have captured many thousands of shapes (contours) in various forms for custom seating systems. The predominant methodology employs a plaster casting technique and as a result, shape information is often retained in the plaster cast, therefore has not been measured and may well not be recoverable over ti...
