“It helps with his facial drooping in the first instance, but he’s still got a very long journey about learning how to speak and all that stuff again.
“It’s all down his right side and so his arm, his leg and his mouth are all quite badly affected, so he has trouble. He goes through phases. He’s got a phase where it affects his speech and being able to express himself properly.”
