The resting spine. A conceptual approach to the avoidance of spinal reinjury during rest.

During periods of rest, the human spine assumes many different postures. This article examines the patterns of stress exerted on the lumbar spine by the more commonplace reclining postures. It proposes a rationale for choosing an optimal resting posture. In the event that the spine is injured, this study suggests that a sleeping posture that will minimize the stress at the level of injury should be adopted.
