[Ergonomic aspects of sitting].
Although basing on anecdotal rather than scientific evidence, it is now thought that adopting a poor posture while seated is involved in the present "epidemic" of back pain. This poses the question as to what constitutes a correct sitting posture. Surprisingly, the literature offers little verifiable information. An adjustable angle between the seat and the backrest would appear favorable. Armrests are also recommended for certain activities. It is important that the chair can be adapted to the dimensions of the individual, and to the needs dictated by the surroundings. Innovative chair designs are controversial, and most may be recommended only as a "training device". Car seats create special demands, and should always be subjected to functional testing. In conclusion, scientific data on the ergonomics of sitting are sparse. Further controlled studies are urgently needed.
