Stroke Survivor

Hi im posting in regards to my dad who had a stroke back in march this year , his leg is coming on really well but his arm is not doing alot he has shoulder movent and bicep movement but not a lot else was just wondering where we go from now to try something new , we currently have a stroke team who come round about 5 times a week and have been working on his arm aswell but they will be signing him off soon, i have seen the saebo products would they be any good or are there any other suggestions?
Thanks and hope ive posted in the write part . Also he did have a mri scan because he was having alot of pain in his shoulder and that has come back as a damaged tendon or trapped tendon.

Thanks Sam
