Hi Dee - You’re welcome and thanks again for sharing your expert / first hand knowledge about RLT devices.
It’s nice for me to see a post from someone like you who is “looking to leave no stone unturned to aid recovery” as it is fairly rare for various reasons. I am a carer for my Mum who also suffered extensive brain damage following an ischaemic stroke back in 2019 but we have not been able to do anything anywhere near what you might have been doing for your husband.
I am pleased your husband seems to be responding to the Vielight neuro pro.
If you have not had a chance, you may wish to search this forum for other posts on the subject or anything else you wish to know about - there are many knowledgeable stroke survivors and carers on this forum who happily share their experiences 
As you are looking to “leave no stone unturned”, I will take the liberty to put you in touch with Roland @pando with whom I have had a few discussions on doing all you can to beat the stroke. Roland has tried all sorts of things including RLT and is very happy to share his experiences with us. Recently he has started a YouTube channel where he posts videos which you may also find worth watching.
Wishing you all the best.
