FDA Approves Marketing of Motorized Device for Paraplegics

The U.S. Food and Drug Administration allowed marketing of the first motorized device intended to act as an exoskeleton for people with lower body paralysis (paraplegia) due to a spinal cord injury. ReWalk is a motorized device worn over the legs and part of the upper body that helps an individual sit, stand, and walk with assistance from a trained companion, such as a spouse or home health aide.

According to the U.S. Centers for Disease Control and Prevention there are about 200,000 people in the United States living with a spinal cord injury, many of whom have complete or partial paraplegia.

“Innovative devices such as ReWalk go a long way towards helping individuals with spinal cord injuries gain some mobility,” said Christy Foreman, director of the Office of Device Evaluation, at the FDA’s Center for Devices and Radiological Health. “Along with physical therapy, training and assistance from a caregiver, these individuals may be able to use these devices to walk again in their homes and in their communities.”


ReWalk is for people with paraplegia due to spinal cord injuries at levels T7 (seventh thoracic vertebra) to L5 (fifth lumbar vertebra) when accompanied by a specially trained caregiver. It is also for people with spinal cord injuries at levels T4 (fourth thoracic vertebra) to T6 (sixth thoracic vertebra) where the device is limited to use in rehabilitation institutions. The device is not intended for sports or climbing stairs.

Prior to being trained to use ReWalk, patients should be able to stand using an assistive standing device (e.g., standing frame), and their hands and shoulders should be able to support crutches or a walker. Patients should not use the device if they have a history of severe neurological injuries other than spinal cord injury, or have severe spasticity, significant contractures, unstable spine, unhealed limb fractures or pelvic fractures. Patients should also not use the device if they have severe concurrent medical diseases such as infection, circulatory conditions, heart or lung conditions, or pressure sores.

Patients and their caregivers must undergo training developed by the manufacturer to learn and demonstrate proper use of the device.
