The BOTTOM line is YES! You can use a walker, walking frame, Rollator, etc. You are still propelling yourself forward using your legs. THAT is the critical thing here.
The rest of the contraption is basically to maintain balance and stability, and to give you a ready place to rest. Many of the Rollator type rolling walkers have integral seats and a small storage compartment - a good place to store water bottles.
My very ill wife is using one now, recuperating at home after three extreme abdominal surgeries in two weeks, and six-weeks in hospital. I have communicated with many others who have a fair amount of experience with these things to come up to speed on hope they can be used. I learned a lot over the past month.
The KEY PIECE of advice they related to me, and which I will relate to you, is to make sure you obtain a rolling walker frame (or Rollator) that is suitable for off-road use. While you may have to take the paved route many times, you will still be on gravel and packed soil trails much of the time. Think about what you would use to walk in a local park with fine gravel paved trails, for a few hours. Then scale-up that assessment for walking some 15 miles - 24 km daily.
Try to find a product that incorporates useful features like:
- larger diameter tires.
- slightly wider tires - baby stroller tires will not do it - for long.
- ?possibly pneumatic tires (filled with air or soft foam"? If such a thing is available,
- a storage compartment with a low center of gravity
- LOCKABLE hand brakes, and
- a stout enough frame - consider obtaining a Rollator or walking frame for a Plus-Sized person. It may have all the features you need. These items exist. But you need to search.
Finally, to add some style and to make her more visible once she is able to go outdoors, I customized my wife' s Rollator with a proper bicycle bell (the brrr-RING!!! type) not a wimpy ding-ding hammer.
I first used this type of bell when I lived in Belgium for several years, and experienced the Dutch-like bicycle culture first-hand. If you did not move to the right when hearing the loud brrrr-RING! of the approaching bell, coming fast from behind you, the next sound you hear will likely be the Heavenly harps.
I also added neon colored streamers on the handlebar ends to make her more visible. This is similar to what many of us did as children. The trick is to find something with a high color contrast against the background or reflective. The idea is to attract a motorist's attention.
In this regard - customizing a rollator - you should be able to source a mounting bracket - normally used with a baby stroller or pram - to enable you to attach a walking or golf umbrella with a long shaft. This will help protect you in hot sun or light rain. Heavier rain still requires a poncho or another type of rain gear. I advise a neon colored golf umbrella for safety. I use one for walking. Obtained it at Decathlon.
I sincerely hope this helps.
