The unit where I work in No. Calif. has an exercise program involving stationary bikes for patient use during treatments. At the onset of the program, staff was a part of it also, with teams of staff and patients together committing to various out-of-clinic physical activities that would accumulate in "team points". There were about 4 teams, results were posted, and it got a little competitive. Walking was the main activity for patients. That seems to have been a good initial motivator for beginning some exercise. Now, a number of patients use the bike in the unit, the average time is about 20 minutes.Everyone interested was medically evaluated before beginning and okayed from a cardiac standpoint. All patients are monitored throughout and nursing assessments determine initiation or continuance of each bicycle use. There is more to this info. I saw your message earlier, wrote down a name, ph. #, and address for details and then left it in my pocket at work. I'll send that to you as soon as I get it. Hope this helps. Good luck!
