According to Canadian academics who ran a short trial of such electric pants on 37 people, the mild current actually mimicked fidgeting, while preventing such bedsores from forming. It might be a good idea to get it implemented and sold eventually though, as the Royal College of Nursing did some calculations and claimed that such sores cost the NHS up to a whopping £2 billion per annum. Apparently, being zapped with 10 seconds of stimulation every 10 minutes for 12 hours a day should be able to do the trick, and I do wonder just how uncomfortable it would be to be on the receiving end of such electric jolts.
