Arthritides: An Upfront Look at a Back Seat.
NIOSH 1979 Jun:129-130
Seating postural factors that contribute to musculoskeletal disorders are discussed. The author mentions that most seating is designed for aesthetic, rather than for functional or health reasons. Properly designed seating involves an optimal alignment of the spine to minimize skeletal stresses and adequate clearance for the buttocks to prevent inordinate stresses caused by the juxtaposition of the seat and the pelvis or dorsal spine. Depending on functional requirements, the chair should allow for appropriate motion and should be adjustable to accommodate differences in user sizes. The author suggests that certain types of furniture can be constructed to meet specified seating requirements if function, body configuration, and specific musculoskeletal problems are considered. As an interim solution, he recommends the modification of poorly designed seating by the addition of simple adaptations such as chair leg extenders and seat cushions.
