bad knees or low mood? blame the way you walk! scientists investigate whether changing your gait can improve physical and mental health - where can i buy dry ice packs
Few of us think about how to put 1 feet of our weight in front of the other half, but scientists are looking at whether changing the way we walk can protect our physical and mental health.
A promising focus is how changing our gait can reduce our risk of knee arthritis.
The most common type is osteoarthritis, usually starting in middle age and gradually causing cartilage damage.
Cathy Holt, professor of bioengineering and plastic engineering at Cardiff University, is looking at how the way people walk can trigger this.
She believes that teaching people to change their gait in middle age can save them decades of pain --
Avoid knee replacement surgery later.
Professor Holt says bad walking habits can hurt.
To put it simply, walking too far with your knee, or too close, can put extra pressure on the inside of your knee.
Some people may bow down a little. Leg or knock
Professor Holt said he is also a spokesman for charity against arthritis.
However, the way people walk may be affected by minor injuries such as cartilage tear or deformation.
So when they take a step, their knees are pushed out of the right route.
This overload on one side can cause a series of cell damage.
In a healthy knee, the cartilage and joint bones under it maintain constant communication, and the cartilage indicates that the bones release new cells and rejuvenate the tissue to compensate for wear and tear.
Professor Holt said that if your organization is loaded as expected, then the system works fine.
But when you are overloaded, the signals between the organizations change and they react badly.
Then the system is over.
As part of the normal process of our bones, the cells that break down the tissue constantly renew themselves.
This overproduction can lead to degradation of bone and joint and cartilage.
At the same time, this system also produces excessive cytokines.
"Immune cells that cause pain in inflammation and typical burning arthritis," Professor Holt said . ".
She and her team are working on the gait.
Correct retraining therapy for people aged 40 and 50.
Other studies focused on changing the gait to reduce pain in arthritis.
For example, on 2013, Pete Shure, a professor of mechanical engineering at Shanghai Jiaotong University, asked 10 knee arthritis patients to walk on the treadmill while wearing monitoring equipment to give them feedback on their walking.
Participants learned how to transfer the walking load to the best part of the knee joint.
After retraining, the patient reported that their pain had been reduced by nearly third.
Their ability to walk has improved similarly.
Professor Shull and his colleagues at Stanford University in California are working on wearable devices.
Meanwhile, Professor Holt is trying to teach people how to change their gait.
"We asked them to walk in a different style --
With a wider gait-
See if this can bring about a beneficial change, she said.
Other studies have shown that changing the way you walk can also help prevent depression.
The latest evidence appeared in February, in a study reported in the Journal of the American Institute of geriatric medicine, which monitored more than 50 Irish 4,000 healthy people in four years.
It found a close link between poor gait and later depressive disorders.
Dr Robert Briggs, a Dublin senior medical research expert and Irish longitudinal research fellow on aging, said lower walking speeds and shorter steps indicated a significant increase in the risk of depression.
Gaits poor people may exercise less, he said, probably because they find it troublesome to walk, and it is known that energetic walking can prevent depression.
But other studies have also revealed an interesting add-on: Studies have shown that we can improve our mood if we walk "happily.
On 2014, Dr. Nicholas terroger, a sports biologist at Queen's University of Ontario, Canada, trained 39 volunteers on a treadmill to develop a happy or sad gait in an upright or drooping posture.
After a few hours, they had to remember positive and negative words.
People in the "frustrated walking" group remember more negative words.
The difference in recall, he said, suggests that a frustrated way of walking actually makes the mood even more depressed.
