Hi there Ursula I am in Australia so not sure if this will be relevant for you. Over here we have riding for the disabled which is a brilliant program, the facility has lots of very patient horses and lots of adaptations to ensure all abilities can have a memorable fulfilling ride one way or the other. Alternatively people are able to just pat horses, watch them act. If you could take your residents to a place like this or to a horse stable. Alternatively research equestrian places that may bring ponies to you for your residents to pat, groom etc not sure this is helpful, good luck.
