The field calls it prosthesis rejection. The people it describes mostly call it a decision.

Studies spanning decades have found that a meaningful share of upper-limb amputees stop using their prostheses, and that the reasons are practical, not a failure of attitude. What the data shows, who it describes, and why the community conversation barely acknowledges it.

The intake form at an O&P clinic usually has a checkbox: Do you currently use a prosthetic device?

The answer “no” requires an explanation. What the form expects is either “not yet” (you’re waiting to be fitted) or “I was never fitted” (you haven’t been through the system). What it doesn’t have room for is the more complicated answer: I had one. It didn’t work for me. I made a decision.

That decision, choosing not to use a prosthesis, or stopping after trying, is documented in the rehabilitation literature at rates high enough that it should have reshaped how the field talks about outcomes. It mostly hasn’t.

What the research actually shows

Studies on upper-limb prosthesis use have consistently found that a meaningful share of people who are fitted with a device stop using it within months to a few years. Reported rates vary depending on how “non-use” is defined, what amputation level is included, and which population was studied, but across different methodologies, estimates typically run between 20 and 35 percent for upper-limb amputees. Our upper-limb prosthetics guide covers this finding as a clinical baseline worth understanding before any fitting decision. What it doesn’t do, and what this piece is trying to do, is spend time with the people that number describes.

That’s roughly one in three, or one in four, depending on the study. That is not a rounding error. And that’s before you account for irregular use: people who put on the device for some activities and not others, or who use it occasionally but not as a daily driver. The numbers for “not a primary tool in my life” are higher.

For lower-limb amputees the rates are lower, and the dynamics are different. A leg prosthesis often provides a more unambiguous functional benefit for ambulation, particularly for community ambulators. But lower-limb non-use exists too. It’s most common in older adults with dysvascular amputations and significant comorbidities, many of whom are assigned a K0 or K1 functional classification and end up primarily using a wheelchair. That population is enormous. Dysvascular disease accounts for the majority of amputations performed in the United States. They are also the population least represented in the prosthetic success story, which tends to feature younger, more active users.

The language is doing something

The clinical term for stopping prosthesis use is “rejection.” Sometimes “abandonment.” These describe what happens accurately enough: a person was fitted, and the device is no longer being used. What they also do is frame the prosthesis as the expected outcome and its non-use as a deviation that needs to be explained.

That framing matters because it shapes how the question gets asked. “Why aren’t you using it?” positions the device as the default and the person’s decision as the problem. “What would need to be different for it to be useful?” is a different question. The first one is common. The second one is rarer.

People who stop using a prosthesis are not, in the main, people who gave up. Many of them went through fittings, worked with therapists, tried multiple devices, and adjusted their daily routines around the device before concluding that the net benefit wasn’t there. That conclusion can be entirely correct given their specific anatomy, activity profile, and life. The language of rejection doesn’t capture this. It implies something was refused that should have been accepted.

The real reasons

The research on why people stop is actually fairly consistent. The same factors come up across studies separated by decades:

The device didn’t outperform not having one. This is the dominant reason for upper-limb non-use, and it’s the one the field is slowest to sit with. Many people with unilateral below-elbow amputations adapt to one-handed function thoroughly enough that a prosthesis, which requires energy to operate, adds heat, and takes time to don and doff, doesn’t provide a net gain for their actual tasks. The adaptation isn’t a workaround. It’s a functional outcome that works.

Comfort problems that couldn’t be fixed. Harness friction. Heat. Skin breakdown at pressure points. A suspension system that loses its fit as residual limb volume changes across the day. These are engineering and fitting problems, and they’re real. Some can be resolved with the right prosthetist, the right socket, and enough adjustment time. Some can’t. When comfort fails, the device stops being worn.

Not enough training. A prosthesis requires time with a skilled upper-limb therapist, not a few sessions, but sustained practice. That training is inconsistently covered by insurance and frequently inadequate. A device fitted without sufficient training has a high probability of ending up unused, not because the person couldn’t have learned but because the support structure needed to learn wasn’t there.

The device wasn’t built for what they actually do. The dominant use case that drives prosthetic hand design is the bilateral grip task. Many people’s daily lives are not primarily organized around bilateral grip tasks. When the tool doesn’t match the work, it doesn’t get used.

Who this actually describes

The non-use data skews toward upper-limb users, but the people it points toward are more varied than the statistics suggest.

There are adults who lost a hand or forearm decades ago and built a life using adaptive techniques: specialized tools, environmental modifications, one-handed methods so ingrained that a prosthetic device would require unlearning what works. They may have tried a device at some point, or declined to. They have navigated careers, families, and sports. They do not appear in the prosthetic outcome literature because they are not in the system.

There are older adults with dysvascular lower-limb amputations who use wheelchairs as their primary mobility because the energy cost of prosthetic ambulation isn’t compatible with their overall health. They did not choose between the prosthesis and the wheelchair as lifestyle options. The determination was made with them by their care team, often quickly, in a system that was moving them through a rehabilitation pathway faster than it was explaining one. They are also not in the success story.

There are people who tried prostheses and stopped because the system didn’t give them the follow-up, the training, or the adjusted socket that might have changed the outcome. That’s a different kind of non-use, not a decision made with full information, but a gap in care that looked like a decision.

These populations overlap and are not the same. What they have in common is that the community infrastructure (the peer support programs, the media coverage, the benefit-navigation guides, the fundraising narrative) is mostly built for people who are currently using prosthetic devices. The rest of them find the room less organized around their experience.

What the community conversation omits

The “inspiration” frame that Moxie Calder usually distrusts is, at least in its most common form, a frame about prostheses. Person loses limb. Person gets fitted. Person competes, or returns to work, or holds their child’s hand with a prosthetic one. Camera shot. Caption about not giving up.

The frame isn’t wrong about the people it depicts. It’s just not the only people there are.

A community that tells its story primarily through device use implicitly tells the people without devices that their story is different, or incomplete, or requires additional explanation. The community is broader than that. The Amputee Coalition represents people across the full spectrum of limb loss and limb difference, including people who don’t use prostheses. Peer support programs like the Amputee Coalition’s Peer Visitor Program can connect people with trained volunteers who’ve navigated similar situations, and it’s worth noting explicitly that those situations don’t all include a device.

What it would take to shift the conversation is not complicated. It’s saying honestly, in the places where the community defines itself, that the range of outcomes includes not using a prosthesis, that this can be a valid and well-considered outcome, and that the support structure should work for those people too.

That’s a much lower bar than it sounds. It mostly requires not defaulting to an assumption.

Amputee News does not provide individualized medical, fitting, or insurance advice. Prosthetic decisions depend on your anatomy, functional level, lifestyle, and care team’s assessment. For questions about whether a prosthesis is right for your situation, a physiatrist or prosthetist with experience in your amputation type is the right starting point.
