Navy SEAL Lieutenant (junior grade) Brandon Myers knew something was off the day he decided to run the fabled BUD/S obstacle course over his lunch break in August 2015, while assigned to SEAL Team 7 in Coronado, California.

According to a profile in the official Naval Special Warfare (NSW) blog, Ethos Live, the Pittsburgh, Pennsylvania native and son of a steelworker had just begun to descend the approximately 50-foot-high cargo net on the course when he tangled a foot, lost his grip on the net, and fell to the ground. 

Myers hit hard, and instantly realized he could not feel his legs. He had become, in that brief moment, a paraplegic, told by his doctor that he would never walk again. Just like that, the SEAL’s career was over and his life was changed forever.

The 26-year-old was defiant in the face of his doctor’s claim, determined to prove the physician wrong. Today, he is quite literally one step closer to that goal, as he becomes the first San Diego-based U.S. Department of Veterans Affairs (VA) patient to receive “robotic legs.” These will allow him to walk upright for a few hours per day. The story was first reported in the San Diego Union-Tribune on April 19, 2017.

Called the ReWalk Exoskeleton, the device was approved by the Food and Drug Administration (FDA) for VA patients with paralysis in December of 2015. The device is made by ReWalk Robotics, based in Massachusetts, Israel, and Germany, and costs $77,000 on the open market. This cost is out of reach for most disabled veterans, absent the VA’s help.

The ReWalk was invented by a paraplegic Israeli man, which seems fitting: Who better to understand the needs of such a device, as well as the importance of functionality and simplicity in its design? It works by using motors and sensors to help an individual achieve a level of mobility similar to a person walking on crutches. 

In simple terms, the exoskeleton works in the following way: A sensor worn on the waist is triggered by the individual leaning forward, indicating a coming step. A small computer worn on the back then sends signals to motors located at the individual’s hips and legs, which move the wearer’s legs by use of the exoskeleton. The wearer also uses crutches for balance, and a watch that allows the user to switch between sitting, standing, and walking.

ReWalk estimates that as many as 10,000 paralyzed American veterans may one day qualify to use the device. According to the Union-Tribune report, suitable candidates are only five years into their paralysis, are between 5’2″ and 6’2″, and weigh less than 220 pounds. They also require good upper-body strength and movement, among other criteria.
