Her trip from bed to bathroom is not the same length as yours. You may cross the room in a few long strides without thinking. She may take short steps, stop at the bed edge to catch her balance, and hold a wall for three more steps before the door. If you size the route from your own walk, the numbers can look fine on paper and still fail her at 3am. So the first measurement on this route is hers.

Walk it with her, in daylight

Pick a time when she is rested and her usual walking aid is within reach. Ask her to get up the way she does at night: sitting first, then the feet, then standing. Do not hurry her. Watch where she pauses, where she reaches for a surface, and which way she turns her body. Keep your hands close but off her unless she asks for help. Walk the whole trip once, from the bed edge to the toilet seat and back.

Count her steps and mark the floor

Count the steps she takes, not the distance you think she covers. Write the count down. Then lay painter's tape on the floor at the bed edge, at the bedroom door, at the start of the hall, at the bathroom door, and at the toilet. These marks are the six stops on your floor plan. Measure the distance between each pair of marks with a tape measure, and write it next to her step count for that leg. Each leg gets two numbers, distance and steps. Where the two disagree, that is usually where she is working hardest.

Note the pauses and the hold points

Write down each place she stops, sets a hand down, or shifts her weight. Note how long she waits and whether she has to turn her body or can keep her face forward. Then note what she holds: a wall, a door frame, a dresser, or nothing at all. A pause with nothing to hold is the one to look at first. At night she will find something to steady herself, and that something may not be stable.

Check the trip in the dark

Repeat the walk with the lights off and someone nearby, keeping it short and safe. Compare the new step count with the daytime one. Darkness often adds steps: she slows, feels for the wall, and may make a second pass at the door frame. Record the night count beside the day count, and mark any pause that shows up only in the dark.

Read the two counts together

A longer count in the dark means the trip is harder when she cannot see the floor, so the light and the surfaces along the route deserve the first look. A pause that appears only at night points to a light, a shadow, or an object she cannot see, not to strength alone. If she has already fallen on this trip, start with the steps in the first ten minutes after a fall, then come back to the counts.

Bring both counts and your list of pauses to her doctor. Ask whether a walking evaluation from a physical therapist would help, and ask which of the pauses the doctor thinks matter most. You can fix the route, the light, and the surfaces in your house. Questions about her body, her balance, and her medical care belong with her doctor.

What to write down

  • Bed edge to bathroom door: steps and distance, by day and in the dark
  • Each pause: where it happens, how long it lasts, and what she holds
  • Each tape mark you laid, with a note on what it stands for
  • The day and time of each walk, and who was nearby
  • Questions for her doctor, written in the order the trip happens
