Pressure sores affect people who are unable to change position regularly.
Treatment of pressure sores also requires reduction of pressures at the damaged area of skin. Special support surfaces, aimed at pressure redistribution, including beds, mattresses and cushions, are widely used and range. It is unclear to what extent these surfaces can prevent or treat pressure sores and whether any system is better than any other. There was no restriction on articles based on language or publication status. Trials with similar patients, comparisons, and outcomes were pooled.
