Ask Slashdot: What Would You Look For In a Prosthetic Hand?

Soulskill posted about a year ago | from the swiss-army-fingers dept.

Medicine 173

Arglebarf writes "A family member is recovering from a serious illness and, unfortunately, the medication that saved her life will probably cost her hands and feet. She is an artist by trade, so this is a pretty big deal. Replacement prostheses might restore a degree of independence, as well as enabling her to continue with her creative passions. Do any Slashdotters have experience with replacement hands? What features do you look for? Do any models allow you tweak the software for fine tuning? Beyond the day-to-day uses, she will want something that can hold small objects precisely (e.g. a paintbrush)."

There is no doubt in my mind that for now, transplant wont be an option. It is experimental and, probably more important, risky.

A sturdy socket, and a 3D printer. While highly dexterous neurally controlled arms and hands are in development, they're far from an off-the-shelf option. For specific uses (e.g. holding various artists tools) you may well be better off with some sort of magnetic socket on a stump cup, and a rack of special purpose end manipulators for each tool.

Mouth will probably work better than prosthetics (5, Informative)

Big_Breaker (190457) | about a year ago | (#43670011)

For paint brushes and other small items I imagine holding them in her mouth will work better than current prosthetic hands.

You may be thinking about the robotic hands you can see in research clips but most available prosthetics are simple devices that open and close with a turn of the forearm.

The robotic hands suffer from difficulty getting a "close/open hand" signal from the brain. Implanted electrodes are all to some degree incompatible with human tissue and degrade over time. Sensors to read electrical signals through the skin are imprecise. Some versions use buttons manipulated by other body parts (likely toes in this case) but these are not in the mainstream.

The old fashion two finger hooks seem to be the most practical answer for a lot of people. They are cheaper, durable, don't require batteries and can do a lot of useful things with any fine motor manipulation.

A human hand is a marvel of biological engineering. Sadly it is tough to replicate in a prosthetic. Perhaps she would be a good candidate for a transplant down the road? Prosthetics may improve more quickly with so many vets having suffered limb loss. To date lower limb prosethetics seem to be well ahead of hands/arms in terms of matching the original limb's functionality. Lots of "below the knee" single amputies have no obvious impairment in terms of gait.

Upgradability, replaceability & interchangabil (4, Insightful)

schwep (173358) | about a year ago | (#43670013)

Technology is moving very fast. State of the art today won't be in 5 year. I would want a system that I could disconnect the replacement part(s) and connect up new ones without surgery. This also allows for custom limbs for specific tasks. Holding a brush may be a custom limb. I may also want a custom chainsaw arm, too.

I want flexibility for change & all the specifications for the mating connector to my body to be open source or license/patent free so I can have custom limbs made. I want a copy of the specs for the same reason.

Re:Upgradability, replaceability & interchanga (2)

mrxak (727974) | about a year ago | (#43671369)

One benefit to the wars we've been fighting, is the advancement of trauma-related medical technology. So many soldiers are surviving injuries that would have killed them in previous generations, leaving them with missing limbs instead. This in turn is advancing prosthetic technology quite a bit.

I expect that we'll see some really great prosthetics on the market over the next couple decades that will put existing ones to shame. Whatever prosthetic this family member gets in the immediate future, she'll probably be able to upgrade to something that improves her quality of life dramatically fairly soon regardless.

Anyway, opensource or licence/patent free commercial artificial limbs, while technically possible, I believe are practically impossible at lest for now. Legislation(FDA, etc) on this tech is the harshest and from my experience as a medical engineer they don't like any time of user customization (and for valid reasons, for MOST of the time). You might be able to build your own from scratch or buy compatible parts from some unlicensed(or pirate) vendor in the future, but most likely it will void all warranty and insurance you have on the prosthetic device.

Indeed, it is a challenge to get used to at first, but after going to school with a major burn survivor who had the krukenberg procedure on both arms and was able to win the audition to be the drummer in the top jazz band at a prestigious music school for multiple years, it seems like the procedure allows amputees to do more than any prosthesis.

Re:What kind of artist? (4, Interesting)

Miamicanes (730264) | about a year ago | (#43670621)

After reading about them, I can't help but wonder whether an interesting prosthetic compromise might be to somehow attach muscle fibers to implanted force-feedback strain gauges, then use the strain-gauge readings to control the hand itself (possibly in conjunction with all-electrical sensors used with other nerves to provide additional control. In other words, instead of pulling on bones, the muscles would pull on artificial ligaments cemented onto strain gauges attached to some kind of stretchy/springy plastic that itself is attached to a worm gear that moves the far point closer or farther from the muscle to alter the resistance.

For finer control (like individual fingers), it would take an idea from the way HTC's hybrid mechanical-capacitive switches used on their last few Windows Mobile and early Android phones worked. Basically, they used capacitive means to determine WHERE (approxiamtely) you were touching the phone, but used an actual switch triggered by a press anywhere in the region to determine when you actually intended to fire a switch event.

In a similar manner, the hand's controller could attempt to discern things like individual finger control by sensing the nerve bundle directly to come up with blunt motions, but sanity-check it in realtime against the muscle-triggered strain gauge, and use fuzzy logic to correlate patterns of nerve activity with specific variants of strain-gauge muscle tension to produce an intended action (so the actual finger, for instance, curled in direct response to the real-world forearm muscle pulling on the implanted strain gauge).

The problem with non-mechanical nerve interfaces is that they basically have the same kind of problems that capacitive touchscreens do... terrible signal to noise ratio and processing latency compared to real-world direct actuation. Nerves aren't like switch-triggered wires in a harness... they're more like a bundle of coax carrying multiplexed spread-spectrum QPSK signals with unbelievable amounts of background noise. By directly interfacing a few muscles with strain gauges, we can bypass the hundred (give or take) years of R&D it's going to take to get signal processing up to the point where it really needs to be, and just take advantage of the signal processing that the forearm muscles ALREADY HAVE to pick out the right signals and translate them into commands for the prosthetic hand.

but consider this : a replacement hand wil never give her back what she already had. It wil always feel worse compared to the original. It may be better to focus on what is left, than on what was lost. There's plenty of artists using mouth or feet in stead. Encourage her to exploit being different and do things differently.

Secondly remberer that all her skillz reside in her brain even after having lost the hand/limb. It may be more easy relocating those skillz to an other part of her natural body than trying to reenact things with an artificial extension.

Insurance doesn't cover a "fucking prosthetics guy". If she's lucky her insurance company will buy her a hook. If got something so bad as to need whatever drugs are killing her hands and feet, the insurance company probably figures she's lucky enough that obamacare removed the lifetime caps and they were hoping she'd run out of benefits so they could drop her to die, so they'll give her the runaround for the next five years, then buy her one hook (pick a limb).

Or, she's a wealthy artist paying cash for four limbs, probably $20k+ each, though if her art isn't interpretive dance, she might go for cheap legs and focus on the hands.

SAVE THE NERVES! Sorry for shouting but... (5, Insightful)

Anonymous Coward | about a year ago | (#43671741)

Sorry for shouting. But save the nerves. I run a regen med research lab, and there is lots of cool stuff coming down the pipe. I know, I know, Real Soon Now, but advancements are on the way. The big limitation is going to be nerves though. No matter how much cool stuff we put together with artificial bone and patient-specific stem-cell derived muscles etc, it's all moot if you can't control it properly, and the nerves, for a variety of reasons, will be the hardest part to regenerate.

Fortunately, there has been some really interesting work done in terms of rerouting the nerves (both motor and sensory) - basically, if the nerves don't attach to anything, they die. But, if before you amputate, you take the nerves and move the ends over so they now lie against skin and muscle etc that will not be amputated, the cells remain alive (and functional). This has lots of interesting applications in terms of interfacing with prosthetics, but also in 5 or 10 years (or longer, if so - sorry, everything is often slower and more complex than we hope), this means the nerves are still there, waiting to be connected to the regenerated limb. Here is one paper that discusses it in more detail:

I don't want to give you too much false hope about where the technology is going - I am very excited about the potential, but there are still a number of obstacles. So, live for today, but there is hope for tomorrow as well.

Just like amputee athletes have prosthetic legs specialized for running which they don't use for walking around on a day-to-day basis, she might benefit from a prosthetic specifically made to hold a paintbrush, or one where the end of it actually is a paintbrush. That could be both cheaper and more usable than a prosthetic hand which attempts to use intricate finger controls to try to hold a paintbrush.

Good thinking. Actually any prosthetic that could have a small hole drilled in the end, where a paintbrush with a rubber band around the stick portion could be fit into the hole...this would allow easier replacement when working on different types of strokes.

Fast Developments in Open Source Prosthetics (0)

This market is moving rapidly and function keeps improving.

As one example "5-year-old [Liam] is missing parts of his right hand, and this open-source prosthetic hand has given him a jolt of increased function. The video clip after the break shows him on the third day with the device. He’s practicing picking up coins from a stack using the hand. Just $150 in parts, combined with the hard work and good nature of the developers, made this possible."

For lower limbs, Jaipur Foot/Leg/Knee have had incredible performance for being inexpensive
"Sudha Chandran, an Indian actress and dancer, lost her limb in an accident in 1982. She was fitted with the Jaipur Foot and started dancing once again; her journey is the theme of the Telugu 1984 film Mayuri (Peahen), remade into a 1986 Hindi film, Naache Mayuri (Peahen Dancing). Both the films starred Sudha."

With these rates of change, a replacement every two years would, I think, make sense. The idea of using specific appliances makes a lot of sense.

Hope she heals and that this is a mood discussion.

A simple clip to hold the paintbrush is sufficient. In fine arts painting, the finger tips are still, and most of the guidance comes from the arm and body movements as in classical fencing. Monet in old age had very gnarled hands from arthritic joints and had to have his family strap the long handled brushes to his wrists so that he could continue painting in the loveliness of his gardens.

A USB port so I can type faster than actually using my hand?
