The human body thrives on movement and will suffer when movement is not possible. A patient who cannot move is at risk of developing serious complications that require complex care. Complete and prolonged immobility can cause serious health problems and deteriorating health, including serious complications. Some of the more common and important complications include pressure sores/ulcers, venous thrombi, bone loss, muscle wasting, contractures, lung infections, and pulmonary complications. Preventive care is vital to avoid these conditions from developing. Prevention is far more effective than treating the condition once it has developed.
