She is very fearful going down steps facing forward, but insists she want to go to a family gathering that requires her to go up a full 14 steps. Two people will be helping her, so I think she'll get up okay. Facing the descent is more scary, even with a person in front of her. I see no recommendations online for facing backwards or sitting on each step. Has anyone tried either?
Have you spoken to her doctor about this " feeling " she has?
Now what to do at someone else's house.... I can't envision a lady of 92 going down the stairs by siding on her backside and trying to slide from one step to another. My Dad [94] has tried that at his own house which has stairs that are U shaped thus there is a landing for him to rest, and he said he was exhausted.
I wouldn't recommend going backwards down the stairs as that is so unnatural that anyone helping Mom could fall in the process.
Best bet is like you had mentioned having two people helping Mom.... have Mom hold onto the handrail with someone holding her arm as a guide. Now a younger bigger person could be in front of her as a buffer in case she feels she will fall, but note whomever is in front could also fall.
I recommend whomever is helping Mom to do this quietly, the softer the voice the easier depending on her hearing.... no loud WATCH IT, MOM, DON"T FALL, as that could startle her.
One of my Mom's doctors had recommended a single vision pair of glasses when she doesn't need close up vision... like glasses used for driving, looking in the distance. The doctor said it would make walking easier so she could easily step up or down at a curb, instead of using her foot like one does to stick their toes to test to see how cold the swimming pool water.
having written all that I see the original question referred to going down stairs.
I would guess the easiest would be sideways. Have Mum face the rail and hold on with both hands. Let the strong leg lead. Put the strong leg on the next step then bring the weak one down beside it and repeat. Mum will be steady enough holding on with both hands to look down and see where the next step is so she won't get disorientated. A circle of helpers of course is needed for safety but don't stop letting her have fun if she really wants to go.
My mom did the backwards stair climbing going down and it worked for her - she had bad hips and knees, and they had let an OT recommend and get good stair rails installed that served her well. She eventually fell off a step stool trying to clean a closet that did not need cleaned, though....
The height was about half the step. Generally, one of us would hold onto her, sometimes with a gait belt and the other would move the baby step from one fixed step down to the next one.
What this did is temporarily reduce the height of the riser so she didn't have to step as far, putting less stress on her legs.
You can get a gait belt on line at Walmart or probably at any pharmacy and they are under $20. I would recommend that anyone caring for an elder get one. Like I said you'll be amazed at how much help such a simple thing is!
Getting back to the house, another good option is to downsize to a smaller one story house with no steps. You will also find that there are places that will build you a ramp over your porch. When visiting people who have stairs, I try to avoid it as much as absolutely possible and have them come to me after explaining the situation. This is something you can try because it definitely works for me. If your loved one is open to hosting in her home, this would definitely be a big win for everyone. Anytime someone is afraid of falling down the stairs due to a problem with the lower extremities, this is a sure sign that they should probably just avoid the hazard all together, and that's where I firmly stand because you'll never find me in the ER with a stairs related injury, especially a head injury. Again, I am a firm believer are in prevention, even if prevention means complete avoidance. This is why am so glad that more or processes for incidences are becoming more accessible than ever before
These also aren't that easy to install. There was a good DIY Holmes Makes it Right episode in which Holmes, an experienced contractor, had to finish up an installation that wasn't properly done. It was not an easy, or cheap, project.
