Millions rely on wheelchairs for mobility, but repair delays are hurting users

More than five million Americans use wheelchairs. Getting one repaired is hard.

Wheelchairs restore mobility to people who are unable to walk or have limited ability to do so. Over a lifetime, this may describe many of us due to changes in health, injuries, neurological conditions, or disabling conditions like arthritis. So, when wheelchair technology or parts quit working, a quick fix would seem essential, right?

I know this firsthand. Unable to walk from decades with multiple sclerosis, I keep small scooters on every floor of my 1911 home, which is further adapted for accessibility with stair lifts and ramps. One day when I turned on my second-floor scooter-type wheelchair, sparks arced from the tiller opening atop the steering column, followed by smoke and the acrid smell of burning electrical wires. It was late on a Friday afternoon. No emergency repair service exists for wheelchairs or scooters. Now what?

Wheelchair repair delays are far more than an annoyance

Wheelchairs allow millions of Americans with mobility disability to participate in daily activities and community life (note: automatic download). We know this improves physical and mental well-being and overall quality of life.

On that Friday, my only option was to have my husband bring my first-floor scooter to the second floor. There I stayed, awaiting repairs on the now-inoperable scooter while my husband brought my meals upstairs. Because I have used the same small assistive technology company for more than 20 years — and have the owner’s cell phone number — by midafternoon on Tuesday, I once again had functional scooters on both floors. My confinement had lasted only four days. I know I was lucky on many levels.

But what if I lived alone, didn’t have another operational scooter, or hadn’t been able to wait four days? And what about people experiencing far longer waits for help with an essential device? While the 1990 Americans with Disabilities Act (ADA) prohibits discriminatory policies and requires physical accessibility in public services and spaces, it says nothing about this issue.

How often do wheelchairs break down?

Ideally, a wheelchair should be safe, reliable, and match your activity goals and functional needs. It should provide strong postural support and seating that protects against pressure injuries. Depending on strength and endurance, you might wish to self-propel a manual wheelchair. Or you might need a mobility scooter or power wheelchair propelled by a battery-powered motor, one that might even have sip-and-puff operational assistance or a chin-operated trackball.

Regardless of complexity, however — from basic manual wheelchairs to sophisticated rehab power chairs — all wheelchairs can break down, leaving their users stranded. Factors like broken pavement, inadequate curb cuts or soft terrain, steep inclines and inclement weather, and poor wheelchair design pretty much guarantee this.

In one study of 591 wheelchair users with spinal cord injury, 64% reported needing at least one wheelchair repair in the past six months. Among users requiring just one repair, wheels and casters posed the most difficulties for manual wheelchairs (46%). Electrical systems (29%) and power/control systems (27%) caused most problems for power wheelchair users. Rates of wheelchair breakdowns have increased in recent years, and vary across wheelchair manufacturers.

Repairs are costly, in more than one way. A survey of 533 wheelchair users with spinal cord injury found:

  • Out-of-pocket repair costs ranged from $50 to $620 (the median, or midpoint, cost was $150).
  • Time spent experiencing adverse consequences from wheelchair breakdown before repair ranged from two to 17 days (five days was the median).
  • Among those reporting adverse consequences, 27% were stranded inside their home, 12% were stuck in bed, and 9% were stranded outside their home.

Wheelchair repair delays are lengthening: Could right to repair laws help?

Lengthening repair delays (automatic download) that heighten risks to consumers’ physical and mental health have caused many wheelchair users across the US to voice their outrage. However, reducing repair wait times isn’t simple. Medicare moved to competitive bidding in 2011, causing most small vendors — like my assistive technology company — to leave the business.

The two behemoths owned by private equity firms that now dominate the marketplace focus on boosting profits and cutting costs. By reducing technician hours and parts inventories, restricting consumers’ access to parts and software passcodes, requiring pre-approvals from insurers for repairs, and other practices, these companies virtually ensure delayed repairs.

Furthermore, Medicare and other insurers do not pay for preventive maintenance such as tightening loose bolts and cleaning casters, allowing problems to go undetected until breakdowns occur. Training can allow some wheelchair users to perform preventive maintenance tasks, but such training programs are not widely available.

Trying to reduce repair delays, Colorado’s governor recently signed the first “right to repair” law in the US for power wheelchair users. Complex software programs control many functions of power wheelchairs, and by holding this software as trade secrets, the manufacturers and large vendors have forced consumers needing repairs to use their services.

Much like recent right to repair laws for cars, the Colorado law mandates that power wheelchair owners and independent repair shops have access to the embedded software tools, parts, and other resources required to diagnose, maintain, or repair power wheelchairs. Other states, such as Massachusetts, may follow. Power wheelchair users in Massachusetts are testifying at public hearings about their repair horror stories to motivate the legislature to act.

Given the complexities of the wheelchair industry, it’s not clear whether right to repair laws will shorten repair times for power wheelchairs. Additionally, this law does not address manual wheelchairs or scooters like mine. Clearly, much more remains to be done to ensure timely wheelchair repairs. As wheelchair use surges, with growing numbers of baby boomers with mobility disability wanting to remain active in their communities, solving the wheelchair repair crisis is increasingly urgent.

Corneal transplants becoming more common

At one time, replacement parts for the eyes must have seemed unimaginable. Nowadays, if the inner lens of the eye becomes clouded by a cataract, a routine surgery to swap it out with a new artificial lens restores vision.

But what happens if the outer lens of the eye (the cornea) becomes damaged or diseased? You can have that replaced, too. “It’s not as common as cataract surgery, but many people get corneal diseases after age 50 and may need a corneal transplant,” says Dr. Nandini Venkateswaran, a corneal and cataract surgeon at Harvard-affiliated Massachusetts Eye and Ear.

More than 49,000 corneal transplants occurred in 2021 in the US, according to the Eye Bank Association of America.

What is the cornea?

The cornea is a dome of clear tissue at the front of each eye, covering the iris and pupil, that acts as a windshield that protects the delicate eye apparatus behind it, and focuses light onto the retina, which sends signals that the brain turns into images (your vision).

You need this combo of windshield and camera lens to focus and see clearly. But many things can go wrong within the five layers of tissue that make up the cornea. That can make it hard to see and rob you of the ability to read, drive, work, and get through other activities in your day.

How does damage to the cornea occur?

It may stem from a number of causes:

  • Injuries, such as a fall. “Falls are a big reason for people to come in with acute eye trauma. The cornea can be damaged easily if something pokes it,” Dr. Venkateswaran says.
  • Previous eye surgeries. “Especially for adults who’ve had several eye surgeries — such as cataract and glaucoma surgeries — the inner layers of the cornea can become damaged and weakened with age,” she adds.
  • Illness. Problems like severe corneal infections, or genetic conditions such as Fuchs’ endothelial dystrophy, can cause vision loss.

What are the options for treating corneal damage?

Cornea treatment depends on the type of problem you have and the extent of the damage. “It’s a stepwise approach. Sometimes wearing a specialty contact lens or using medications can decrease swelling or scarring in the cornea,” Dr. Venkateswaran says.

When damage can’t be repaired, surgeons can replace one or a few layers of the cornea (a partial-thickness transplant), or the whole thing (a full-thickness transplant).

The vast majority of transplants come from donor corneas that are obtained and processed by eye banks throughout the US. In some instances, such as when repeated transplants fail, an artificial cornea is an option. Recovery after corneal surgery can take up to a year.

How long-lasting are corneal transplants?

There’s always a risk that your body will reject a corneal transplant. It happens about a third of the time for full-thickness transplants. It occurs less often for partial-thickness transplants. Preventing rejection requires a lifetime of eye drops.

Still, transplant longevity varies. “I’ve seen transplants from 50 or 60 years ago and now they’re starting to show wear and tear. Other patients, for a variety of reasons — immune system attacks, intolerance to eye drops, or underlying conditions — may only have a transplant for five to 10 years before they need another,” Dr. Venkateswaran explains.

Preventive eye care can help preserve the cornea

It’s crucial to get regular comprehensive eye exams to make sure your corneas and the rest of your eyes are healthy.

The American Academy of Ophthalmology recommends a comprehensive (dilated) eye exam

  • at age 40
  • every two to four years for people ages 40 to 54
  • every one to three years for people ages 55 to 64
  • every one to two years for people ages 65 and older.

You’ll need an eye exam more often if you have underlying conditions that increase your risk for eye disease, such as diabetes or a family history of corneal disease.

If you have any vision problems, such as eye pain, redness, blurred vision despite new glasses, or failing eyesight, see an eye doctor.

Fortunately, for people who do experience corneal damage, advances in surgical options are encouraging.

“Corneal transplants are a miracle,” Dr. Venkateswaran says. “I have patients whose quality of life was significantly decreased because they couldn’t see through their cloudy windshield. We can give them sight again, and we have the technology and medications to keep the transplant alive.”
