Hi Christina, i am getting an amputation in 2 months time, and did not have a lot of info, so I googled and wow! I got so much from all your video posts, and what to expect! Thx for this I believe you are helping a lot of amputees around the world! Im from SOUTH AFRIC and sharing your feed to many people! Well done your positive outlook does rub off!
Thank you for your videos. They are very informative and encouraging. I am a BK amputee and have been for almost 1 year. You certainly have a lot of knowledge about the hardware we use and I really appreciate you sharing it.
The reason is related to the science of thermodynamics. A looser liner won't facilitate heat transfer the way a tight liner will. The heat generated by our limbs will be absorbed by the coolest area surrounding it.The less open space the more efficient heat transfer becomes. HVAC engineer when I lived in Georgia and as such had to become intimately involved with Thermodynamics. Hope this helps.
Nice presentation. I've been 45 years on AK prosthesis and I can vouch for the gel liners. Before they were invented every day was bloody and painful. Only mistake I caught was your saying that 6mm is the maximum thickness. I've worn an Ohio Willow Wood ALC 5096E for years that is 9MM.
+Butch Carter It's mid October 2015 and I had an AK amputation in May of this year... I have tried a LOT of gel liners and the Willowood is FANTASTIC! It has the pin in front with a solid connection to my femur stump socket. As long as you keep the gel clean, they stay stuck to your leg!... I'm looking forward to my prosthetist moving me up from the "pinto" range of prosthetic leg to the Mercedes "C" leg by ottobock!
I'm not an amputee, I'm doing research in designing an adjustable socket but, from the engineering perspective, I think it has to be with heat transfer. If the liner is very tight then heat, is transferred out to the socket walls. If it is loose, then heat is trapped inside and then it condenses and becomes water. I'm not sure, but I think that is the reason!
Samuel Terrazas I'm a below th knee "amp", the water does not condense, a more compliant (tight) liner makes the covered residual limb transfer the heat to the air better than a loose one that will act as if it's an insulation layer which traps heat and then the body creates the swear to promote cooling.
Excellent presentation. I love it and learned a lot. I'm 1 year into my below the knee left leg amputation. I too have a ICEROSS liner (no waves) thanks to an excellent amputee consultant. I never paid attention to the name or the quality. Thanks for answering this for me. For sweat I dab Povidone Iodine solution after bathing. And sprinkle pure 100% ZINC powder in the liner both after bathing and every couple of days. It mops up sweat and growth of any microbes thus no smell whatsoever.
If the liner hugs your skin tighter the sweat glands tend to close up I have been an amputee for 13 years and have used many different kinds of liners for about 9 years
Please suggest me i am want to try first time liner my budget is low , but suggest me best , that is long durability ,and comfort, i can't afford to waist my money, please
About the sweaty liner issue, it might be caused by the air in between your loose liner and your leg. That air can warm up a lot more. It's the same with clothes, tight clothes are not favorable in cold weather, whereas puffy loose clothes are. This is because they trap more air, that your body can heat up. I don't know if this is the same for liners, but it seems kind of logical to me.
Pretty much that. The air actually works as an insulator preventing heat getting off of the surface of the material. Also, as you said, air keeps the energy in it really well. With tight clothes the heat goes right into the denser and colder material and from that the energy goes to the colder air around it which then rises higher making more room for cold air. Through the cycle the first material stays cooler than with hot air trapped surrounding it not being able to transfer enough energy
Hello my name is Al Amirault I lost my left leg below the knee two years ago I have a new foot #2 that's bends as I walk its on me for about 12 hours a day with no problems at all my right leg is no straight yet but it is getting there. I am using a cane and every know and then walking without it I am 72 years old you have giving alot of good information for me thank you
Most antiperspirants work by blocking the pores of the sweat glands, preventing the sweat from leaving. The resulting back pressure prevents further sweat production (osmotic pressure is limited). Similarly, your tight fitting liner traps the sweat in the pores, creates backpressure, and so reduces the amount of sweat produced.
Christina, I love this heat question. I tend to believe the "trap'd air" hypothesis, and tend not to believe the "mechanical counter pressure" hypothesis. Air is a poor thermal conductor, and assuming that it's poorer than the liner (which itself is probably not great), it should slow the conductance of heat from your nub. I guess. I don't know. Maybe. Could there be a difference in the materials themselves as well, in terms of thickness or conductivity? Can these gels be made more conductive?
I am a 65 year old with a traumatic AKA for 16 years. I have never had to remove sweat accumulation from my liners even in Florida however my stump does appear to sweat more when there is an air leak from a hole in the bottom of the liner.
The answer to your question is pressure, because there is less space for air to be trapped so there is less space to store sweat and the sensors in your skin for sweat work on the heat of air in the liner so the difference between the two is one is looser (more air space) and one is tighter (less air space
I wonder if it has to do with the body knowing its contact surface, for example moisture increases friction so if its slipping around, the residual limb knows to sweat to increase friction and therefore stability
I love your video's very informative even for someone that is not an amputee. But I was wondering something els. Your rings, they remind me of my aunts rings and she had rheumatism. May I assume that you also have this?
Now I'm new and need any advice I can get. Bilateral above the knee amputee. All my scabs are not healed yet. I was told to go from the floor into my wheelchair, then I would be ready to walk again. I got from the floor into the bed, but that was easy. I got on my belly and pulled myself across the matress. But the wheelchair is different. We are going to start with stubbies so atleast I won't break a hip, trying to walk... I'll just be like a baby learning to walk, if I fall I can catch myself. I'm going in the next couple weeks so I can get my right stump cast. I think that's what he said.. I'm in the rehabilitation center since leaving the hospital. I feel so much better and I get around real good. I don't like this covid, but we get tested. I had it or they said I was positive for covid. They put me in a private room but I had no symptoms at all. I got moved to a suite so I enjoyed that huge smart tv.. They gave me all kinds of pills until I threw those things up.. But that was the worse part. Someone said I was a carrier that's why I didn't get sick. My linner is a " Willow Wood"
how can you warm your liner mine is so cold sometimes i dread putting it on i put it under bedspread at foot of bed at night i have a chair that heats so i put it beside me some and that helps just wondering what others do
I can vouch for how limiting crutches are. I had to use them once after having foot surgery. No weight at all for a week & a half. Just getting around w/o trying to carry something is difficult & carrying something w/o a handle is pretty much impossible. I can see why people chose a prosthetic. Once it's on there's more freedom to get around.
Did the EDS complicate things a bit with finding a liner that works well for you? Just asking since us zebras tends to have a bit more sensitive skin than the average person. I can personally get blisters from Crocs lol
Using crutches instead of a prosthetic is severely limiting long-term. You can't hold anything while you're walking and you can't safely do things like bend down or run or play sports. Not to mention the repetitive stress on your shoulder muscles could be damaging long term.
Please tell me which is better pin locking system or suction system, I'm a new amputee and my liner get loosened after walking some meters because of that my leg started paining.
AmputeeOT hi I have the same liner as yours but once the screw goes to the socket I find it really difficult to walk like it is very heavy and painful when does this reduce.? According to your experience.
Yes, perhaps the liner "blocks" one's pores. I use a product called "Certain Dri" to control excessive perspiration on my residual limb. Did you receive my email, Christina? : ^ ) ~Hilton
Some people (including me) just like to wear multiple rings. It has nothing to do with rheumatism, arthritis, or any other medical condition. I'm guessing your aunt just liked to have multiple rings on her fingers, too.
They will listen to you: As a very healthy, well spoken and gorgeous looking amputee, I encourage you to see the BIOM iWALK POWERFOOT vids and reach out to them to make some improvements on their prosthetic bionic leg(s). Namely making it affordable, silent (for theft/safety issues), self powering (recharges with every step) and all weather/water proof. Thanks.
your american right? they have a huge array of different things there cos in oz they have jack been an amputee since a baby an had basic prosthetic probably cos there govt issued
hello I am leg amputee also and hopping and dreaming I can't afford prosthesis here in the Philippines if you are poor and specially you are disable and no work how did I earned money for my prosthesis 😭😭 now my life is useless and I fell so bad and sad crying every night...and unconfident and stressed for my situation now because I am amputee and my wife is leaving me she cheated on me because I am disabled now 5months ago when I was surgery to amputee because of the limb doktor was told me, you need to remove your left leg above knee because my bone is affected 😭😭 I am suppering depression untill now.....I don't know how to recover for my situation I need prosthetic but sad to say I don't have money my parents are not afford for the prosthesis,,, 😭😭 I'm looking for someone to help me for any kind of prosthetic.....I'm hopeless can't buy my dream prosthetic leg😔😢🤧
I see that is very complicate to use a prosthecs leg , i think that is best use a cruthe , no have manintence and not complicate, is take and walk. thank you.
Amber1ize If you think my information is incorrect, tell me where and why. I don't see any "seasoned" amputees out there on RUclips giving out this kind of information, so if you're one of them, maybe you should start your own channel.
Not true at all I know amputees who have been So for 20 or more years with the way technology has changed they have no idea of the options out there due to their money situation and or location. It's like the way I use to judge doctors old ones know the ins and outs and the young ones tend to know the new and up and coming. Neither is right or wrong and experience is subjective and circumstantial for all.
I am a seasoned amputee. I was born with the rare condition called fibular hemimelia so my leg had to be amputated when I was 6 months old I am eleven now
Hey, just wanted to let you know that I think that your positive attitude is really inspiring. Keep up the good work!

Wow!! Thanks Christina you really explained a debate I have been having with this issue about liners. Thanks
the tighteness of the liner causes a vasoconstruction which allow les blood in the sudoral glands , perhaps that's why. i am loving your videoes

You and your videos change my life :D!

Hi christi nice videos some more required of running leg extreme and extend
I love your video's very informative even for someone that is not an amputee. But I was wondering something els. Your rings, they remind me of my aunts rings and she had rheumatism. May I assume that you also have this?
My left leg is amputated from above the knee, I am Indian . from Mumbai and you where are you from. Nice vidios
Good presentation type of liner
I am new to the amputee world. just got my leg so any tips or info you can give me. I thank you in advance.

do u have to be fitted for each of these or do u just buy them n sizes n also how much does it cost?
Do they loosen up in time my liner feels too tight.
Great video
how can you warm your liner mine is so cold sometimes i dread putting it on i put it under bedspread at foot of bed at night i have a chair that heats so i put it beside me some and that helps just wondering what others do
Ich glaube es ist eine schwache Durchblutung ( bin je doch kein Arzt )

I'm curious. Why the OT in your channel/screen name?
Also, that opening animation for your channel is pretty cool (in my opinion).
Using crutches instead of a prosthetic is severely limiting long-term. You can't hold anything while you're walking and you can't safely do things like bend down or run or play sports. Not to mention the repetitive stress on your shoulder muscles could be damaging long term.
Air is being let in to the looser liner which can get trapped in side and get heated. Like a sauna effect
Please tell me which is better pin locking system or suction system, I'm a new amputee and my liner get loosened after walking some meters because of that my leg started paining.
Sounds like you need to add socks.
@@AmputeeOT ok by the way which system are you using suction or pin locking system?
Wish you talked about insurance covering liners. I have a high deductible plan and fund them to be very expensive. Any idea on costs?
cool video.
After below knee amputation how much time I wait forwear the prosthetic leg
most are the same thickness mine is a pin liners and yes i have alots of them
How much time to take for heal the below knee
amputed wound
Friction causes heat .... if it's loose and moves there is friction, tight and no movement, no friction ...
True but I don't have a problem with friction.
I've never actually had that problem!
AmputeeOT hi I have the same liner as yours but once the screw goes to the socket I find it really difficult to walk like it is very heavy and painful when does this reduce.? According to your experience.

now strate pins i had bsd luck with now i use the weged pins
i love the rings u wear whered ya get them frm
Does it get wet? When you go swimming?
no, she takes it off
my liner only lasted around a couple of months is it the way i wash it of just crap?
Einen Leiner kann man ohne Probleme mit ca. 40 Grad nieder Temperatur in der Waschmaschine waschen
How does one reduce limb's sweating? Is it even possible?
Some people (including me) just like to wear multiple rings. It has nothing to do with rheumatism, arthritis, or any other medical condition. I'm guessing your aunt just liked to have multiple rings on her fingers, too.
Hi This is BHIMAN HARVANI what about conical shape stump liner
Good lord she is beautiful from inside and outside!!
Youre so cool.
Thanks.
tight liners keep your pores closed and the loose liners let the pores open
Please tell me my brother is in very pain

what about skates can you still skate?

pistoning causes sweating
Wounds new treatment
If air can get into the liner your stump will sweat.

Oh you know what your talking about, but your a newbie that's all. Not even a year into it.
Actually I have been an amputee for a year and a half. Which I suppose is still new. This is an older video.
Amputee for 23 years, get on my level *flex* lololol
AmputeeOT We should nub wrestle *wink* =D
Being an amputee, only seven months is hardly an, experienced amputee.
If you don't think I know what I am talking about, then tell me exactly where I am wrong.
you chew your nails. . tsk tsk
You don't have much experience as an amputee. How can you even comment? a seasoned amputee of 8 or more years really know better.

Hi.. Is it possible to repair the liner if it get a hole in it?
