1)Putting him in cold water then hot water then cold again 15 minutes each will help move his blood and help the healing process.
2)streching out his muscles for him once or twice a day, someone has to do that for him at least once a day every day.
3)Electronic muscle stimulation, you can shock him with one of those and move his blood and prevent muscle wasting for free at home for him.
4)Anyone can work his muscles or even needle or cup him it's not that hard.
