6 Minute English - Is knuckle cracking good for you
Oh. Don't do that please Neil. That's my fresh creep.
Oh dear. If something makes you feel fresh creep, means you feel frightened or disgusted by something. I don't know why I do it. It just feel nice.
But you are lend with other righter when you are old, you know. After writer is a disease that causes pains and swelling enjoin our bodies.
That's an old wild tales, Rob. That means an old idea or believe that has no scientific support.
OK. I see professor.
And since you are in scientific mood, how about answering today's quiz question? which types of joint can you crap? Is it
a) fribes
b) XXXX
c) Sinnoval
OK, this professor isn't feeling too clever today. I am going to take a guess and say c) Sinnoval.
OK we'll find out how smart you really are later on in the programme. Now listen to XXXXX, professor of Rehabilitation medicine in the university of Albato. Rehabilitation means the process of helping somebody gets better from the illness or injures.
We have recently been able to use some technology through MRI imaging to see for the first time what actually happening inside the joint when someone passes or crocks their knuckles. And because of that, we hope for that we'll be able to start to ask question about why is there are some people can do this and other people can't.
What does MRI stand for?
It means magnetic Resonance Imaging. Hospital uses technology the image inside a person's body.
So some people can't not crack their knuckles, can you Rob?
I don't know. I am not about to try. But it isn't just figure knuckle it crack, you can do with your knack, back, knees, ankle on toes.
Professor XXXX says comparing people who crack their knuckles to people who don't might provide inside or understanding into who joins are healthier.
Sounds interesting but what actually happens when you crack your knuckles, Neil?
Well. When you stretch or band your finger or pop your knuckle, you are making a bones of the joy pull apart, like this.
Please don't do this again.
Well, it stretches its space around the joint and surrounding fluids and courses of decreasing the pressure as a result gust dissolute to the fluid become less soliable or less able to be dissolved leading to the formation of bubbles. And when you stretch the joint full enough, these bubbles burst, producing pop sound.
Ouch, excellent. Well thanks for the biology demonstration, Neil.
Any time Rob. Let's hear from professor again about the medical value of research into knuckle cracking.
When our engineers XXX do this, between two flat surfaces sealed. When you do recently and pull apart quickly, and there is little fluid between decking you electronic might cross to see the tremendous damage to the surface of the joint. But for some reason we don't see that, in the human joint. There is something make this very XXXX.
Interesting stuff. So scientists have preformed experiments to imitate what happens in the human joint when you crack the knuckles. When you quickly pull apart the pealed XXX or clay tile with fluid between them, it causes a lot of damage to the surface of the tiles.
Why don't human joint stanch damage?
Well the scientists don't actually know. They can see the damages in the tile using the special electronic microscope. That is a very powerful microscope. But it's not clear what makes human joints resilient to damages. And resilient to this context means returning to its original shape after being stretched or banded.
Right. But with further research, scientists may be able to find out and use this information to help people with joint problem.
Oh, let create a synthetic or man made materials which can withstand wear in tear better in column ones. Withstand means not being damaged by something. And wear in tear means damages as a result of olden reuse.
Can we have the answer to today's quiz question now please, Rob?
