So they've built something to assist where the body is at it's weakest... The point is that this is a realistic movement people can find themselves doing and this is research into making that better/safer. In complete isolation, this might be completely replaced by different lifting technique. But what about in cramped quarters where turning isn't easy, or with an awkward object? What about in combination with other devices which make the body strong along another axis?
