When Josette Sykes had a knee replacement three months ago, she needed rehab to get back on her feet.
But the pressure on her joint from walking was painful. so her physical therapist recommended she try an antigravity treadmill.
"I love this machine. It's like walking on a cloud, no stress, no pain," said Sykes.
By pumping air into the sealed clear bubble, and adjusting for the person's weight and injury type, patients feel like they are walking or running on air, which takes away the pressure on the joints.
The treadmill was originally designed by NASA to help astronauts train for zero gravity conditions, but physical therapists and elite athletes realized that running and walking on an anti-gravity machine was perfect for training as well as rehabilitation.
After a month on the treadmill, Sykes has better movement in her knee, than if she went through standard rehab. She has lost weight, and she's recovering faster. All with very little pain.
