If the medical profession is anything like the manufacturing industry, not enough ergomic lifts are available. "Lift with your legs", lofl.
From reading male and female nurses comments both, back groans seem to resonate constantly. So if EVERYONE suffers, I would imagine the guys suffer more since 'they are better equiped naturally to do overload weight lifting exercises'. i.e. instead of getting 4 female nurses, one male back per few months (and then fire for some boneheaded HR excuse) may seem more economically feasible for the Bookkeeper.
Work physiology speaking, lifting 'live' loads that can move in an infinite span of directions and forces would be perhaps the WORST thing to lift per actual weight. Even thos portable lift devices seem like a hazzard to use after a few times: it may get better, but stooping, reaching, and trunk movement of handler and handled required! Add a little repetition and extreme back strain incidents every couple of days, and wallah, you are the patient. Just hope its not as an $11/hr CNA working on RN degree.
This is a serious concern the Female nurses know well how to avoid incidents. I'm a little surprised that there are no engineer work physiologists yet in persuit of RN goal has not yet contributed. If not, I don't mind, as I've measured every effect in milliseconds of any type manufacturing/industry operation including bicycling (very complex).
All operations effect different people differently, and must just know what are critical parameters (by filming operation). Judging by the fact that women live on the average significantly longer than men, we need to start thinking more with our heads and not by what 'Industry' tells us we should think!
