She may be able to walk with the walker in a wide hospital hall. That does not tell you whether she can use it beside her bed, turn into her bathroom or carry breakfast to her chair.

Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.

Before the walker becomes part of the promise, follow it through her actual day. Use the walker she will use at home. Put on the shoes she normally wears. Keep another person close while she tries each route. You are not testing how determined she is. You are finding where her body, the walker and the house do not yet fit one another.

1. Start with the fit at her hands and body

What makes it hold: She can stand inside the walker rather than reaching far ahead for it. Her hands meet the grips without lifting her shoulders or folding deeply at the waist. She can hold the handles, work any brakes and keep her feet clear of the frame as she steps and turns.

Ask the person who recommended the walker to adjust it while she is wearing her usual shoes. If the walker has a seat, basket, tray or other attachment, test it with those parts installed. They can change where she stands, how she reaches and whether the walker clears her legs.

When it becomes a care team question: Ask for another fit check if she leans heavily onto the frame, catches a foot, cannot manage the brakes, has pain while using it or needs someone to hold the walker steady. Also ask if her height, strength or way of walking has changed since the walker was chosen.

2. Measure the narrowest part of every needed route

What makes it hold: The walker can travel from bed to toilet, chair, kitchen table and outside door without being folded, lifted or turned sideways. Measure the walker at its widest fixed point. Then measure the tight places in the house, including door openings, the space between furniture, the side of the bed and the approach to the toilet.

Do not stop at the doorway measurement. Open each door as far as it normally opens and look for the handle, hinges, wastebasket, bath mat or cabinet that takes away usable space. Decide where doors should rest so she is not trying to move the walker while also pulling a door around her.

When it becomes a care team question: Ask an occupational or physical therapy professional to see the route if she must abandon the walker to reach a needed room, hold furniture instead or squeeze through with her hands outside the frame. The answer may involve a different walker, a different room arrangement or another way to complete that part of the day.

3. Give her room to turn, stop and sit

What makes it hold: Every destination has enough open floor for her to approach, turn and line up before sitting. Test the whole movement at the bed, toilet, dining chair and favorite chair. Watch the walker as closely as you watch her. Its wheels or back legs should not catch a rug, table leg or footstool during the turn.

Choose one parking place beside each chair so the walker remains within reach without blocking her feet or the next person through the room. If it rolls, confirm that she knows when and how to use its brakes. If it folds, do not assume she can open it and make it ready without help.

When it becomes a care team question: Ask for help if she drops into the seat, pulls on the walker to rise, leaves it behind during turns or cannot remember the sequence she was taught. Have the care team watch the movement using the chair and bed she actually has.

4. Test every change in the floor

What makes it hold: The walker moves over the surfaces she must cross without a wheel stopping suddenly or a leg catching. Walk the routes slowly and look at carpet edges, thresholds, floor vents, cords and changes from one flooring material to another. Remove loose items where you can. Check that anything left in place lies flat and stays put when the walker passes over it.

Test the outside route too if it is part of her day. Look at the first step beyond the door, the landing, uneven paving and the place where she gets into a car. Try the route in the conditions she is likely to meet, not only when the floor is clear and dry.

When it becomes a care team question: Stop the test and ask for guidance if the walker repeatedly catches, rolls away from her, must be lifted over a threshold or requires another person to steer it. Ask whether the equipment and the route still match what she can safely manage.

5. Make carrying part of the fit

What makes it hold: She can move the ordinary things she needs without taking a hand off the walker or carrying something that blocks her view. List what travels with her, such as a phone, glasses, tissues, a drink or a small meal. Test the basket, pouch or tray with those real items inside.

Check where each item begins and ends. A cup holder does not solve the job if she cannot fill the cup, place it securely or reach it after sitting. Set up small landing places near her bed and chair so she does not have to balance an object while parking the walker.

When it becomes a care team question: Ask for help choosing another method if she must carry items in both hands, hang heavy bags from one side or reach beyond the walker to set things down. The care team can help separate what she can move herself from what a visiting hand should bring.

6. Repeat the test when she is tired and the house is quiet

What makes it hold: The walker is in the same reachable place whenever she gets up, including beside the bed at night. The route to the bathroom is clear, lit and wide enough without moving baskets, shoes or furniture. Anyone helping her knows where to stand and where not to pull.

Do not judge the plan only by her strongest hour. Watch one needed trip when she is tired, moving slowly or wearing night clothes. Check whether the walker still fits when blankets hang from the bed, a bathroom door is partly closed or another person is in the room.

When it becomes a care team question: Tell the care team if her ability changes across the day, if she forgets the walker when she wakes or if one person must lift, pull or catch her to complete the route. Ask them to name the conditions under which she should wait for help.

A walker fits this house when it supports the whole trip, not just a few steady steps. Write down the routes that work, the places that need a change and the moments that require another pair of hands. That gives your family and the care team something concrete to solve before you build the promise around it.
