There has been a large amount of scientific study done on sitting posture and chair design. To the author's knowledge, no research has been done on stools without a backrest and the relationship of seat pan tilt and sitting posture, with an attempt to directly measure lumbar curvature. In addition, this study used a new type of noninvasive technology applied directly to the subject to study the shape of the lumbar spine. The research conducted in this study addressed this research void by measuring the shape of the lumbar spine using the depth of curvature and spinal curvature inflection point as the dependent variables and the tilt of the seat pan as the independent variable. The results and recommendations of this pilot study can be used to justify a larger study to include more subjects and females as well as males.
