The major reason we put in the automatic stand-by generator last year was to power DW's medical assist equipment, which is a growing list of things.

The other major thing we installed was a "stair riser", that is, the chair you sit on which takes you up and down the stairs. Lets someone who cannot safely (or at all) climb stairs go up and down at will. Regretfully, it is classified as a "luxury" item and not covered by any insurance. Apparently it is considered unnecessary for a disabled person to ever need to use the stairs. (insert irate rant here).

Those were the major cost items. Wheel chair, power scooter, walkers, shower seats, grab bars etc. as needed.

All of those things are specific to an adult muscular dystrophy patient.

On a more general note, IMO the recommendations most health organizations make for a home FAK are woefully inadequate, both in what is contained and the quantity. The ones I see sold in the drug stores are not even in the ballpark. The recommendations you see on this forum are much more useful and realistic.

Also, get some type of comprehensive first aid training, including CPR certification: basic EMT if possible. Remember, when your family member shouts help, you are the help, at least until more help arrives.
