The latest terrible idea is catching on - "anti-gravity" treadmills (and the quotation marks are necessary, in my opinion). If you don't believe me, check here, or here, or here. The idea is that one can go through the motions of running without the impact shock, allowing one to get in a cardio workout that's similar to normal running, while injured. It's like pool running, only the resistance can be varied - and I've never run in a pool, either.
This in-between "making do" is just making people feel that they're accomplishing something other than wasting time. If it hurts too much to run, that's your body telling you something that you should heed. If you can't run for a while, you'll appreciate it all the more when you can.
This almost-running can't be a good thing. When astronauts come back from space, their bones have partially demineralized from the lack of impact of gravity and they're weaker for it. "Anti-gravity" treadmills can only lead to slower callousing and knitting together of bone than if one runs normally until pain tells one to stop. These treadmills may help one to decrease the loss of aerobic fitness, but the bones aren't going to become as strong and you're going to get injured again, so you're going to spend a lot of time going back to these fantastically overpriced machines, rather than running.
Run. Or don't. But don't "kind of" run.
