Hey guys

I have a bit of a problem. i broke my tibia (shinbone ) last July 3 . I have not been able to use that leg and as a consequence my calf has deteriorated in size by about 30%. I need some way to exercise the calf muscle to help build it back up but I cannot perform any of the standard calf exercises and it looks like another 3 months before this thing heals.

I am thinking of some sort of muscle stimulator. Any suggestions?
