Sorry but I disagree entirely and I'm talking from personal experiance a Suspensory will heal better if no strain is put on it and that means complete stall rest.
My connemara put a hole the size of 2 pence coin in his suspensory and a small hole in his check ligament when he was 18 years old (slipped at a show). Stemcell therapy failed and my insurance wouldnt shell out for shockwave therapy (though I have heard amazing things from friends who's horses have undergone it). The Vet said he would never be ridden again and best thing would be to turn him away permanantly.
Got a 2nd oppinion and whilst not much better the 2nd vet did give me hope. We stall rested him for 6 months, turned him away for anouther 12 months, then it took me 6 months to get him super fit (we spent 3 months at walk, seriously building him up). I also got him swimming to help strengthen him. I had him back out and competeing to the same level! Took me 2 years but I did it.
In the first 6 months I iced his leg for 20 mins every 2 hours, right through the night as well, I also put him on Global herbz Tendoneze for the entire 2 years!
When I first brought him back into work he wore tendon support boots.
My experiance of Stemcell therapy was unfortunate because stan was older and his cells refused to divide but I do know of several people who have had wonderful results with it. You are time limited, any more then a couple of months after the initial injury and stem cell therapy is useless.
Shockwave on the otherhand is not time limited. Again I've heard of realy good results from first hand accounts.
Personaly I would go for the stemcells and if they don't work then go for shockwave.
