TORONTO —
In the heat waves of the heat, most torotony people do not have much consideration for cold temperatures, ice and snow, and winter overflowing weather.
But in a special lab at the Toronto rehab center, walking is dangerous. and chilly —
Experience of volunteers like Varun Ohri. A 20-year-
Ohri is a science enthusiast from Mississauga.
If his supervisor, Jennifer Xu, is lucky, he will also fall in love with science.
Hsu is a biomedical engineer and PhD candidate who is good at Gait bioengineering.
She is working on a project at the University of Toronto affiliated hospital that aims to comb through the causes of winter falls, especially if they can be avoided.
Volunteers like Ohri are wrapped in down jackets and sent to the hospital-controlled environmental lab to walk on the iceCoated walkway
Temperature in the room
Like a restaurant.
Refrigerator without food and shelves
Can be set anywhere-20 C to 40 C.
Volunteers Connect motion capture sensors to their shoes to help Xu understand what happens when people start to lose their foothold on the ice.
She records their movements so that she can analyze later things, such as how much the heel slides when it falls on the ice, and how fast it slides.
"I had a lot of setbacks in my studies," she admitted . ".
Xu looked a little guilty when she admitted it was good to fall.
"They are very useful," she said with a smile . ".
"It really taught us a lot when we saw one thing happen.
As long as it is safe and in a good control environment, it will provide us with a lot of information.
Volunteers wear safety belts to prevent them from being completely wiped out.
Their feet may fly from below, but they do not hit the floor;
The harness will arrest an autumn before this happens.
Hsu is working for Canada Post with funding from the Ontario Workplace Safety and Insurance Board.
"Canada Post really wants to be able to protect their employees.
So one of the problems they know is that a lot of people are slipping, "she said.
"So they want to kill it in the bud.
"Crown provides employees with a variety of-
The sliding device, explained Hsu.
"We want to know how good they are --
There is no better.
You may think these questions have been answered.
But in the process of studying how effective a device is, there are so many variables that it is difficult to get an answer in this field, Hsu said.
Different things happen at different temperatures, different types of ice, and different types of surfaces.
Walkways in the lab can be set to recreate many different variables.
A person can be pried like a ramp;
Part of the sidewalk can also be raised to form an icecovered stair.
Hsu wants to use the information she collects to find out what is the ideal design for winter footwear.
"It's not just what's already in the market, it's about developing our designs using new technologies and materials. . . .
"It could be the idea of a 'smart shoe, '" she said . ".
"But to do this, we have to understand what is already there and how people use what is already there.
Then we can also use this setup and everything we are doing right now to test the new product we are designing.
"Ohri, who is about to start his fourth year in biomedical engineering at the University of Toronto, said he taught him one or two things about winter walks in the frozen summer. “Be careful. Walk slowly.
Take your time.
