Hi Thanks to you all for your replies.
My Mum and myself attending one of dad's physio sessions on Wednesday so we can help him with any exercises we can whilst we visit, at the moment they are concentrating on Dad's sitting balance and getting strength back on his trunk and core muscles . In terms of his legs he can tap both feet quite well and yesterday I was getting him to lift his legs about 6 inches off the floor to touch my hand from a sitting and lying down position which he did, I am confident there is good movement there.
The physios said at the moment the brain is having to work hard to communicate with the right muscles which in time will improve , we will keep pushing daily and Dad is a very determined man Thanks All and take care yourselves x x
