ReWalk is a commercial bionic walking assistance system that uses powered leg attachments to enable paraplegics to stand upright, walk and climb stairs.[1][2] The system is powered by a backpack battery, and is controlled by a simple wrist-mounted remote which detects and enhances the user's movements.[3] Designed in Yokneam, Israel, the ReWalk is marketed by Argo Medical Technologies.[4]

The device underwent clinical trials at MossRehab in suburban Philadelphia.[5]

The ReWalk system is priced at approximately US$85,000 per unit.[6]

On July 10, 2014, ReWalk Robotics filed for a US IPO that could raise up to $58 million. The company plans to list on the Nasdaq under the symbol "RWLK."[7]

Versions[edit]

ReWalk has two versions – the ReWalk I and the ReWalk P. The ReWalk I is used by medical institutions for research or therapy to be used under the supervision of a healthcare professional. The ReWalk P is for personal use by patients at home or in public.

An updated version, ReWalk Rehabilitation 2.0, was released in January 2013. The ReWalk 2.0 featured improved sizing for taller individuals and some enhancement in controlling software.[8]

Practical applications[edit]

The ReWalk was approved for hospital use in the United States by the Food and Drug Administration (FDA) in 2011.[3] FDA approval for home and public use was issued in June, 2014.[9][10]

On 8 May 2012, paralyzed British woman Claire Lomas became the first person to finish a marathon using a bionic assistance suit. Lomas, who was paralyzed from the waist down in a 2007 riding accident, completed the London Marathon in 17 days with her ReWalk system.[11] Later in 2012, Lomas became the first person to take the ReWalk suit home for assistance with everyday tasks.[12]

In the American TV series Glee, a ReWalk is used by fictional character Artie Abrams during the Season 2 episode "A Very Glee Christmas".[13][14]

Working[edit]

This ReWalk system weighs around 23.3 kg: the backpack with the system's Windows-operated computer and battery weigh about 2.3 kg (5 pounds) and the robotic legs that can support their own weight, are around 21 kg (46 pounds).[15]

The user can engage in three modes: walking, sitting, and standing. The signals to these modes are sent via a wrist-watch type device to the computer.[15]

Criticisms[edit]

The weight and bulk of the device is considered to be too much, by its creator Dr Goffer.[16]

At approximately US$69,500[15] to US$85,000,[6] purchasing a ReWalk system is considered expensive and difficult to afford for many, especially because, as of July 2014, health insurance in the United States of America does not yet cover the ReWalk.[15]
Larry Jasinki—the CEO of ReWalk—has stated to Mashable that the company is "working with insurers and other health-care coverage providers to ensure individuals eligible to use the ReWalk are able to purchase a system".[15]
