Check out the bit on the new shoe-inspired prosthetic arm design that we're trying to create through StumpworX: Breaking the Mold in Prosthetic Arms By Nate Rawlings. I could use as many Facebook votes (Vote for StumpworX here) as I can to get a chance at winning the $10,000 ro $50,000 in prize money from the…
I've started a for-profit business to serve as the Red Hat to Open Prosthetics' Linux, offering service and support for manufactured prosthetic arm suspension and components. Check out my pitch video and please vote for us to win a $5000 startup competition prize here: http://www.facebook.com/DukeStartupChallenge
We're focusing first on suspension, because it represents the vast majority of reasons that people don't wear arms… Continue
The Times of Malta reports that Martin Calleja's 17-year-old son Luke made him a device that resembles a greifer, after watching him become frustrated about trying to use his above elbow body powered device.
The Becker Hand is one of the longest-running hand-shape prosthetic products around, and has been well described by Wolf Schweitzer in this post. I have been trying one out, thanks to John Becker, who is still in the family business, and plan to do a more detailed evaluation of this… Continue
I've talked a lot about my (still, unfortunately) favorite prosthetic terminal device, the split hook invented by David Dorrance in 1912. There are two basic benefits that this device offers: (1) body-power, or the ability to open and close the fingers to pick up items, almost like a pair of tweezers, and (2) the useful geometry of the design that… Continue
I was fortunate enough to be able to attend the NCD Summit in Washington, DC this year. I have never seen a more diverse collection of people united in their desire to overcome their collective challenges, and celebrate the progress that has been made in government's commitment to helping them do it in the 20 years since the passage of the Americans with Disabilities Act. Tom Perez, Assistant Attorney General for Civil Rights quoted the late Senator Ted Kennedy yesterday in saying that the ADA… Continue

Regarding Paul Hochman's recent Fast Company article on prosthetics, as both a consumer of prosthetic arms and an engineer working on the most ambitious prosthetic arm project in history, I have some significant problems with his portrayal of the clinical state of the art. The basic premise raised in the article, that we're anywhere close to "Super Human Prostheses You'll Envy" is laughable to… Continue
When we incorporated, we imagined that our ideas for open design mattered to many more markets than just amputees, which is why we're the Shared Design Alliance. As one way of tackling problems like ours, I've proposed an open source TV design show for a new Changemakers competition.
Christian Siefkes has written a great post on some of the issues surrounding open hardware and the differences between hardware and software. As one of the comments below notes, the possibility of well-documenting prior art is absent from the analysis, and is another avenue for preventing patenting of design ideas.
While I've complained about the fact that many of us are using hooks strongly resembling that designed by and still bearing the name of David Dorrance, who patented the split hook in 1912 and whose company survives today, there are many benefits to the design. There's a reason that some designs are… Continue
A tip from Brad Veatch of ADA, the developer of the LESA prehensor (not yet available).
A little teflon pipe thread tape underneath the rubber bands on the hook when you replace them will reportedly increase the life by eight times. Brad apparently has data to support this with cycle testing, and I hope we see that in print soon. My experience has… Continue
Congress has made available $112 M in FY09 for medical research to advance treatment and rapid rehabilitation from orthopaedic injuries sustained by military service members during combat or combat-related activities. The Department of Defense(DoD)Congressionally Directed Medical Research Programs(CDMRP) Peer Reviewed Orthopaedic Research Program (PRORP) task in FY09 is to find and fund innovative research that has the potential to make a significant impact on improving function, wellness, and… Continue

I've spoken before about the need for a standard for prosthetic/robotic arm (or leg) control, preferably one also adopted by a larger industry. University of New Brunswick Fredericton (UNB)'s AIF UNB Hand Project has settled on a CAN-based communications system, using the established standard for automotive communication. Under the name of a consortium that has long sought to standardize upper extremity prosthetic control,… Continue

You may remember the controversy before the Beijing Olympics last year surrounding South African sprinter Oscar Pistorius. The International Association of Athletics Federations (IAAF) had initially ruled that the sprinter, with bilateral congenital below-knee limb absence, could not compete at the games. An independent study… Continue
Some of you may know that I was involved in an effort to climb Mt. Denali (McKinley) with a group of disabled veterans. Details about the trip can be found here:
I was forced through the wise decision-making of our guide, Kirby Senden, to abandon the climb on the 14th of June, having reached just over 16k feet and… Continue

My article on the tough realities of designing next generation prosthetic arms and the philosophy behind the Open Prosthetics Project is up on IEEE Spectrum online, and will appear in the March issue of the magazine. There are a couple of edits I wasn't thrilled with, but in general I'm pleased.
To quote the sidebar about how everyone can help with OPP:
"While it’s most natural to want to help within your area of… Continue
I'm going to repeat myself (mostly) from the post I added to the main site; you never know who is looking at what.
For those of you who haven't seen it, our efforts to improve on the well-loved features of the out-of-production Trautman Hook have been profiled in Scientific American Magazine this month. In order to avoid any possibility of confusion with the old Trautman brand, we're going to refer to our new and… Continue

"Lead users," are consumers (individuals or companies) who spur innovation in an industry by contributing innovations often of a greater value and at a faster pace than the companies that produce the products they use. Their innovations are often freely shared and eventually incorporated into products. Far from being an idealist fantasy, lead user innovations can be incorporated into the R&D strategy of a nimble company, enabling quick identification and anticipation of consumer needs. What… Continue
