I know there has been a little interest in this as an aid to vision and balance problems.
I attended my 5th session yesterday and am riding it most beneficial.
The sessions have highlighted where damage has occurred and I undertake various exercises to try and mitigate that problem.
I asked where people could find out about this service more readily so I could pass the info on here and there is an association of behavioural optometrists who have a list of membes so you can find your nearest one. Evidently not all deal with adult brain injury patients but prefer to deal with children with behavioural problems linked to their eyesight.
I have personally found this useful. It does no harm to enquire.
