Now, electric undies to get rid of bedsores
An underwear designed to jolt the buttocks with electricity may be able to prevent dangerous open wounds called pressure sores, researchers have suggested.
Sores form when people are stuck in one position for too long, which compresses the skin and cuts off the blood supply.
Canadian academics said that in a short trial on 37 people, the mild current mimicked fidgeting and prevented the sores forming, the BBC reported.
The Royal College of Nursing said sores cost the NHS up to 2 billion pounds-a-year.
Pressure sores are a common problem in hospitals around the world as patients are often too ill to get out of bed.
Older people are at heightened risk because of poor circulation.
Half a million people in the UK develop sores each year.
Doctors at the University of Calgary tested underwear which placed two pads of electrodes on each cheek.
Patients who were unable to move because of a spinal cord injury were zapped with 10 seconds of stimulation every 10 minutes for 12 hours a day.
The findings, presented at the Neuroscience 2012 conference, showed that none of the 37 patients developed a sore during the month long trial.
The researchers said the device mimicked fidgeting leaving people sitting in a slightly different position.
"Pressure ulcers can be terribly debilitating," Robyn Rogers, a research nurse at the university, said.
"Their incidence has not changed since the 1940s, indicating that the current methods of prevention simply are not working.
"Our hope is that this innovative, clinically friendly system will eventually make a difference in the lives of millions of people," Rogers said.
The researchers said that the pants were popular with nurses and patients, however, much larger studies would be needed to test how effective the underwear was at preventing bedsores.
