It's often easy to take the freedom of mobility for granted. That is until it's taken away.

But now patients suffering from spinal cord injuries and paralysis could have a chance to walk again.

A device called the Ekso, short for exoskeleton, works to redistribute weight and support its user.

Doctors strap the 48-pound body-piece over a patient's clothing. Ekso then responds when a patient shifts their weight into a position for walking.

Users say the technology is a welcomed chance at freedom.

"I just didn't believe that I would never walk again, whether the doctors told me or not," patient, Lisa Sudo, said. "I'm just always looking for a way to prove them wrong."

"In the four visits that we've seen her, she's made a lot of progress. Each time she leaves here, she takes more steps. Her confidence improves," physical therapist Nicole Smith said.

"The best thing is having a conversation with someone and looking them in their eyes," Sudo added.

The bionic suit is already in use at 14 rehabilitation centers around the world.
