I bought my a MOTOmed Viva 2 Lower Body from a company called Medimotion. I first used one at my local physio department and was so impressed I decided to buy one myself. It is passive so it does the movement itself but you can actively pedal yourself at any time too. I still have some power in my legs because of going to the gym but I haven't done anything near as active with my legs as this for years. Even in passive mode I can feel it working my muscles in my calves and thighs and afterwards I get a sort of pins-and-needles feeling because it's getting the blood flowing.

The only small problem is that I can't use the lower-body part of my bike independently as I need help to put my feet in the pedals. My PA and a neighbour help me to do this - so most days I cycle for 30 minutes most days.

My bike also has a hand-cycle and I use this for 20 minutes at least once a day (I can use it completely independently). I find this really helps to strengthen my core muscles which had become very week after having surgery on my spine 20 years ago. I have far less of a tendency to lean over to one side now.
