22-year-old Errol Samuels from Queens, New York, who lost the use of his legs in 2012 after a roof collapsed onto him at an off-campus house party near where he was attending college in upstate New York, walks with a ReWalk electric powered exoskeletal suit during a therapy session with Alexandra Voigt, a clinical research coordinator and therapist, at the Mount Sinai Medical Center in New York City. Made by the Israeli company Argo Medical Technologies, ReWalk is a computer controlled device that powers the hips and knees to help those with lower limb disabilities and paralysis to walk upright using crutches. Allan Kozlowski, assistant professor of Rehabilitation Medicine at Icahn School of Medicine at Mount Sinai hospital, where patients like Samuels are enrolled in his clinical trials of the ReWalk and another exoskeleton, the Ekso (Ekso Bionics) hopes machines like these will soon offer victims of paralysis new hope for a dramatically improved quality of life and mobility. The ReWalk is currently only approved by the US Food and Drug Administration (FDA) for use in rehabilitation facilities like at Mount Sinai, as they weigh whether to approve the device for home use as it already is in Europe.
