This excerpt was created in the absence of an abstract.

The authors of this article are to be commended for their active participation in the research process. They have succinctly achieved their twofold purpose to determine if and how sitting posture changes with the use of a lumbar support pillow. The authors focused their discussion on the postural changes that occur in the lumbar spine even though other measurements were recorded and analyzed. I will also direct my discussion to the lumbar spine.

The results obtained in this study are not surprising. Just as the placement of a pillow under the knee (with the subject in a supine position) will alter the amount of hip and knee flexion, we would expect the lumbar spine to move into a position of more lordosis with the use of a lumbar support pillow. Documentation of commonly held beliefs is needed, however, and this study serves that purpose.
