title: Physiology and complications of bed rest.
abstract: Prolonged bed rest causes major cardiovascular, respiratory, musculoskeletal, and neuropsychological changes. Complications often result from these effects of bed rest, especially when aging has already decreased the reserves in these systems. These problems can be limited by judicious prescription of modified bed rest.
