'Magic Carpet' Could Help Prevent Falls Among the Elderly

Soulskill posted more than 2 years ago | from the let-the-sound-take-you-away dept.

Medicine 87

Hugh Pickens writes "Falls are a major cause of injury and death among over-70s, and account for more than 50% of hospital admissions for accidental injury. Thus, being able to identify changes in people's walking patterns and gait in the natural environment, such as in a corridor in a nursing home, could help identity mobility problems early on. Now, BBC reports that researchers have shown off a 'magic carpet' that can detect falls and may even predict mobility problems. Beneath the carpet is a mesh of optical fibers that detect and plot movement as pressure bends them, changing the light detected at the carpet's edges. These deflected light patterns help electronics 'learn' walking patterns and detect if they are deteriorating. With over 19,700 deaths in the elderly in the U.S. in 2008 from unintentional fall injuries and 2.2 million nonfatal fall injuries among older adults treated in emergency departments, spotting subtle changes in a person's walking habits may help identify changes that might go unnoticed by family members or care-givers. 'The carpet can gather a wide range of information about a person's condition; from biomechanical to chemical sensing of body fluids, enabling holistic sensing to provide an environment that detects and responds to changes in patient condition,' says Patricia Scully from The University of Manchester's Photon Science Institute."

What if it detected a weight profile that was larger than an average step for a period of time longer than a minute, could it call 911 and request 'Elderly Person Down' assistance? Or at least ask if it should call 911 and if no voice response was given then dial it?

I suspect that an elderly person with mobility issues might not want to look after a dog that's roughly the same size and weight as them.

Not a Weimaraner, sure, but a properly professionally trained Labrador retriever from a good bloodline would be incredibly valuable. A German Shepherd would be a good choice, too, but I think the generally-underrated Doberman (a brave, loyal, and extremely smart dog), while a good choice for most situations, is probably too excitable for the elderly.

jerpyro (926071) | more than 2 years ago | (#41238225)

I was thinking that too, or (from the poster above) the dog analogy is another good one. But if it's that sensitive it can find the weight of the person based on the pressure profile and it should be able to tell when a specific individual is lying on the carpet, right? I don't have all the answers, I just think it would have practical applications for assisted living communities so that they can tell if a person takes a fall.

ColdWetDog (752185) | more than 2 years ago | (#41238451)

The 'I've fallen and I can't get up' problem is probably better answered by a bracelet / fob whatever that has an accelerometer, perhaps a pulse meter and a wireless or whatever connection. To use a floor mat to determine whether granny is alive seems complicated.

Re:Help! I've fallen and I can't get up! (1)

Anonymous Coward | more than 2 years ago | (#41238715)

arm bracelets can fall of which should not be too good for false positives. Also a person might fall slowly and still lie there slowly dying of starvation without any alert. A neck bracelet might work, triggering an alert when it is in close proximity to the mat. This should not be a problem as old people who need this stuff generally don't do handstands or cartwheels.

I saw this yesterday. I'm 60, the only time I fall down is when I'm drunk. Sometimes I'm a bit wobbly when I first wake up until I've had coffee, even when I hadn't drank. What would this device "think" about that? My mother had an inner ear problem a few years ago (she's 84), I wonder if this would have kept her from breaking her arm?

Re:Wouldn't wheelchairs be cheaper? (1)

ethanms (319039) | more than 2 years ago | (#41238241)

I think the point is to continue to allow the person to remain ambulatory as long as possible for many different reasons both practical and not. Perhaps also to detect a temporary condition caused by tiredness, TIA or some other event.

Re:Wouldn't wheelchairs be cheaper? (1)

ColdWetDog (752185) | more than 2 years ago | (#41238477)

A phone with a video camera and link to some analysis software (or, heaven forbid, a real person) would work fine. Do this once a month or so - say when the kids show up. Probably a lot easier than the high tech carpet.

Hell, 30 seconds of walking in front of a physical therapist would get you the same info.

Re:Wouldn't wheelchairs be cheaper? (1)

mcgrew (92797) | more than 2 years ago | (#41238297)

Wheel chairs have their own problems and cause further medical problems. A study done a few years ago showed that 100% of the study's elderly subjects, even in their nineties (the oldest), who could walk 1/4 mile (about 1/2 km, 1 km = .6 mile) all were still alive five years later, and the distance one could walk correlated with how long you had to live.

This is only [damn, what's the word? I'm getting old!], but my cousin broke his neck at age 16 and was in a wheel chair the rest of his life -- he died last week at age 70, his mother is still thriving and in her upper 90s, as are all my mother's siblings.

In short, you stop walking, you die. Unless you're young, of course. Even then you'll die younger than you would have.

Better would be to have some sort of Segway-like tech that would help a walking geezer keep his or her balance. Or even a cane; my late WWII-era drinking buddy Ralph used a cane, and I never saw or heard of him fall.

Probably because he was male. Many female falls/hip fractures are not fall -> fracture but actually the other way around - falls that occur when the hip (weakened due to osteoporosis) fractures. No balancing device can help someone stay up in that situation.

Nursing home corridors typically don't have carpets. They are waxed floors that are easy to keep clean with antiseptic because bodily fluids tend to get on them. If you put this "magic carpet" in, how do you ensure it stays as sterile as possible?

For a bonus, it would be possible to track individuals using this data. The carpet would be able to differentiate between the ways different people walk, and in fact would have to in order to cut down on false positives.

Invasion of Privacy! (2)

So what if two people decide to shag on the floor one day? Or while standing up even? Is that gonna get recorded in the carpet's memory banks and get sent back to home base for further analysis?

Re:Invasion of Privacy! (1)

ClassicASP (1791116) | more than 2 years ago | (#41238663)

All kinds of privacy concerns this could lead to as far as what the carpet home-base-database folks have at their disposal. Suppose homebase knows all the homes with occupants that are progressively showing signs of getting fatter. They could sell that information to diet pill marketers. You could also use this to identify other behavior patterns as well. If the subject tends to move from one room to the next more frequently one day, then it could imply that they're doing a lot of pacing because they're nervous about something going on in their lives, and so now they can sell that info to antidepressant marketers. You could even use it for burglary detection. If floor activity is detected in front of a window without having shown any previous signs of walking around anywhere else in the house, you got yourself a window intrusion detection system. That could be a good thing, but of course, now the homeowner will be getting Brinks home security junk-mail.

Not useful in my experience (4, Funny)

vlm (69642) | more than 2 years ago | (#41238213)

In my limited experience watching relatives fall and die soon after (well, not in person, but hearing about it) its not the fall that's the problem, but the heart attack that lead to the pain that led to the fall, or the stroke that led to the fall, or the kidney/liver failure that led to mass confusion that led to the fall... yes these relatives of mine technically did fall and then die, but the "real problem" was what made them fall, not the fall that made them die soon after. So I'm not entirely sure than locking old people in a kids inflatable "bouncy castle" is much help.

Also it seems a stereotype at the hospital/old folks home/hospice that the last thing people do before being permanently bedridden is fall, then they're like chained down or ordered never to stand again, which coincidentally happens pretty late in their decline, so naturally they continue to decline and die like the next week, because apparently standing is not terribly difficult so its one of the last things to go. Come to think of it, it is pretty easy, since its one of the first things kids learn to do...

I'm just saying its not going to make anyone live longer or better, just means they'll get confined to bed rest and die soon after anyway. So its kind of a depressing invention. Kind of the opposite of "let me die with my boots on" type of thing.

If you're still actively reproducing over age 70 let me give you a high five.

Now a magic carpet to prevent pregnant chicks from falling, or little kids before reproducing age, that would be natural selection. This is just being humane.

Re:What Would Darwin Do??? (0)

Anonymous Coward | more than 2 years ago | (#41238513)

Old people dying by falling is a part of nature, hence natural selection. By interfering with the natural death of old people, this magic carpet is preventing natural selection. Just because old people are unable to reproduce doesn't mean that they still don't have an influence on the growth and development of children around them. And between you and me, I would say that a majority of old people who are in danger of death by falling are completely gone in the head and can only have a negative impact on the development of the children in their life.

Anonymous Coward | more than 2 years ago | (#41238851)

Once you've reached breeding age and chosen to exercise your haploid cells, or not, you've achieved your Darwinian potential.

Natural selection is just the combination of genetic expression (you) and your opportunity to pass the genes you possess on for further testing against the environment in which your offspring exist. In terms of natural selection, old geezers become more of an environmental factor. They may act as assistance or drag on successive generations by facilitating survival or competing for sustenance.

I.e., at some point or another, unless you are a biblical character, your potential to breed viable offspring diminishes to zero, and your Darwinian days are over.

Re:Darwin would correct you. (0)

Anonymous Coward | more than 2 years ago | (#41248685)

Social structure is an important part of many animals' survivability, and goes beyond just the individuals actually passing on the genetic material. This can go for either the case of directly affecting how one's own genes are passed on, e.g. grandparents helping their genes pass on via helping their children, or a more general case of one helping their clan/group pass on genes. Otherwise, creatures like ants would not have Darwinian evolution, as anything affecting the non-mating workers would not improve the ability of the workers to pass on their genes, yet could still help the colony pass on genetic material via the queen.

That's great if the carpet can tell when grandma is about to fall, it improves the chances of getting help to her on time. The hard part though is getting it to prevent grandma from falling in the first place. If the carpet could convince her to sit down for a while (without making her think she's just lost her mind) that could go a long way on it's own. A lot of falls are preventable by getting the person who is at risk to sit down for a moment.
