"When he started with us, he was completely dependent with everything he did. Whether it be dressing, or bathing," said Carol Kisner, a hand therapist at United Rehab.

But, despite the adversity, Henderson was able to learn to use the hooks quickly.

Several months later, Henderson's rehab turned high-tech.

Insurance money helped pay for two I-limbs made by Touch Bionics.

Henderson says each one costs more than $50,000 and he's the only person in the world to have two of them.

Here's how they work: an signal in the brain tells the prosthetic to move the muscles and fingers of the I-limb.

Currently, Henderson is re-learning how to do daily tasks such as eating, shaving and other activities that improve his motor skills.

Owning his own heavy construction business is a goal of Henderson's in the future and says he couldn't have made it this far without the help of his rehab team and of course, his family.
