OH has had a couple of OT assessments in the house. Things that they have ordered for him are
Grab rails around the house, especially in the bathroom and by steps (front and back door)
An extra banister rail so he can hold on each side.
Raisers on the sofa and chairs to make it easier for him to stand up
A perching stool in the bathroom so that he can sit to wash, clean his teeth etc
A bathboard, recently upgraded to a bath chair so that he can sit for a shower (we have a shower over the bath)
Ramps for front and back door.
A walking frame (actually we have two - one for upstairs and one for downstairs). He already had a four wheeled rollator from the physio.
Other things that he could have been offered, but didnt need are - a bed riser, higher seat on the toilet (in both these cases ours are quite high and he can manage them with grab rails). A toilet frame if grab rails are not sufficient. A commode if he couldnt get to the toilet.
There are probably other things as well
