The average age was 58 years, 1st risc in developing pressupre sores, with the same nursing interventions. Patients with pressure sores at intemation were not analysed. Results: Reductions of developing pressure sores were observed in both groups. Additional reduction was observed in a group that used MCT, where 2 cases of pressure sores apperead (stage I).
