Applying pressure to bones or joints that have been repaired with surgery brings times
Many for pain. But what if those who have been operated on could rehabilitate their bodies while floating
In the air? It can work, as seen in a rehabilitation clinic that stands
enter the space age.
Astronauts float in zero gravity, and today can
This is also from surgeons, in a NASA pressure chamber, surgeon Charlie Walker says "No
There is no way I would have been able to do so much at this stage without the treatment."
Walker is recovering from his second knee replacement surgery, three months faster
compared to the first analysis. The difference may lie in the pressure chamber.
"You think you're an astronaut. That's what we built it for," he says.
NASA developed the pressure chamber to give astronauts an artificial feeling of
Gravity in space. On the ground the cell cancels gravity. Here, Walker
Weighs about 25 kilograms, which allows him to do sufficient physical activity
without tiring or straining the knee.
The cell helps patients heal in different ways. Reduced gravity, called
Positive pressure helps reduce swelling.
Physiologist Dr. Alan Hargens says, "The positive pressure tends to move the
The fluids are out of the tissues and back into the bloodstream, where they should be."
Although Walker can do the exercises alone, Hargens, from Univ
California in San Diego, says that other patients need the pressure of the cell
in order to stay active.
If they don't start practicing soon enough after surgery, they may lose the
The ability to carry out a similar activity in the future," Hargens says.
Walker is recovering so well, his doctor has cleared him to drive.
Walker says, “It can be a miracle for people who have to go through what
that I passed."
By urging patients to exercise after surgery, doctors believe that
The risk of blood clots also decreases
