Another Robotic Suit

Well, actually, it is the latest version of a company’s exoskeleton.

I just read the article and saw the video on YahooNews. I went to the ReWalk website and learned more about it. It says that ReWalk is the first exoskeleton to receive FDA clearance for personal and rehabilitation use in the United States. Then I noticed that the Stair Function is currently not available in the United States.

It appears to be designed for spinal cord injuries. It also mentions rehab for stroke victims and people with Multiple sclerosis. Yet, in the FAQ Section, it mentions that people with ALS, Cerebral palsy, Traumatic brain injury, etc. can use it. So, it might be something for those of us living with Kennedy's Disease.

ReWalk has over eighty training centers in the United States and hundreds more throughout the world. I don’t know what it costs, but it appears some insurance companies and the V.A. are using it for rehab purposes.

It appears there are three different units. I grabbed this from the article. "The lightweight, small, wearable suit is much simpler than ReWalk’s device that enables paralyzed patients to stand, walk and navigate stairs. Unlike the ReWalk 6.0, which includes robotic leg attachments that can weigh nearly 50 pounds, the soft exoskeleton looks more like the harness construction workers wear for safety than a bionic system. It consists of a waist belt fitted with a motor and battery, flexible cables that transmit power from the motor to the ankles, leg braces and shoe sensors. And it’s all activated by the flick of a switch.

ReWalk has not yet determined how much the soft-exoskeleton suit will cost, but says it will be more affordable than the ReWalk 6.0, which has a list price of $77,000."

Who can use it?

Before using the device, confirm that the following prerequisites are met by the user:

• Hands and shoulders can support crutches or a walker
• Healthy bone density
• Skeleton does not suffer from any fractures
• Able to stand using a device such as EasyStand
• In general good health
• Height is between 160 cm and 190 cm (5′ 3″ – 6′ 2″)
• Weight does not exceed 100 kg (220 lbs)

People with the following conditions should not use the ReWalk™:

• History of severe neurological injuries other than SCI (MS, CP, ALS, TBI etc)
• Severe concurrent medical diseases: infections, circulatory, heart or lung, pressure sores
• Severe spasticity (Ashworth 4)
• Unstable spine or unhealed limbs or pelvic fractures
• Heterotopic ossification
• Significant contractures
• Psychiatric or cognitive situations that may interfere with proper operation of the device
• Pregnancy

Robotic legs: Dermoskeleton technology aims to help B.C.'s disabled

Scott Cunningham, a reporter for the Vancouver Island CTV News, wrote the following article on Paul Lazenby's adventure test-driving the Keeogo. The video and Paul's comments on his experience can be found in my post earlier this week. The potential the Keeogo has to revolutionize mobility for those living with a disability has me more excited than I have been in quite a while.

Robotic legs: Dermoskeleton technology aims to help B.C.'s disabled

It was designed for the military and featured in the movies. Now, a futuristic robotic skeleton could help B.C.’s disabled community. The wearable technology, which looks like something out of the Robocop movies, arrived in the province in January. Designed by a Quebec-based company, the Keeogo device is an assistive walking machine aimed at helping people with mobility issues.

Targeted at people with multiple sclerosis, Parkinson’s disease and other neuromuscular issues, a new high-tech device is giving people like Duncan man Paul Lazenby their legs back. Suffering from Kennedy’s disease, Duncan man Ken Lazenby is slowly losing control of some muscle movement and is happy to be a trial patient for the new technology. March 8, 2017.

“We can see people continue to be active, healthy, exercise and rehabilitate,” said mobility device distributer Graham Plant. “Maybe they can get away from having to use a cane or a wheelchair.”

“It’s fun not to have to think about it,” said Lazenby, as he scaled a flight of stairs that would normally exhaust him. Suffering from Kennedy’s disease, the Duncan resident is slowly losing control of some muscle movement and is happy to be a trial patient for the new technology.

“What things like this offer is hope. Hope for young people who have neuromuscular diseases that they can move freely if they keep what strength they have left,” he said.

Priced at around $50,000, the futuristic mobility tools don’t come cheap. Because they’re so new, most insurance providers have yet to research them thoroughly.
WorkSafe BC says it is not aware of requests for Keeogo devices, but it is open to investigating anything that could help clients.

The robotic walking aids are a class one medical device, meaning they could be covered by insurance, much like a wheelchair. To date, the company HME Mobility and Accessibility, which is distributing the product in B.C., has yet to sell a unit but is in the midst of several patient trials.

Remarkable Canadian invention helps physically challenged

My January 29th blog post was on a new device that might revolutionize how people with mobility issues get around. Paul Lazenby is another person living with Kennedy’s Disease. He had the opportunity to test the Keeogo walking assist device. The Keeogo is designed for people with mobility challenges, but still have balance and some core strength.

The news report shows Paul testing the device for the first time. He looks confident and comfortable. When he took an unassisted step up at about the 1:40 mark, I said, “Now that is amazing.”

I congratulate Paul for taking the time to discuss Kennedy’s Disease in the video.

Paul provided some additional information on the Keeogo.  Batteries last 45 minutes for heavy climbing, 3hrs for walking.  Batteries change out easily, and recharge in about 20 mins. There is a tension control so there is less torgue while walking and the higher setting for stairclimbing. It really does power you up the stairs.

Had it on for two and a half hours, did multiple stairs (plus the big step several times leading with either foot) and walked a fair bit outdoors. The large step would be impossible for me normally without a railing or pushing on my knee with my hands. It really does make stairs effortless for me. When I was out walking, it feels a little awkward, because it still hasn't/won't adjust to my natural rolling pirate gait .. but.. I found my self whistling, and could carry on a conversation when normally I walk with teeth clenched and very focussed.

It feels very supportive and solid. The other gentleman who you see striding by in the video has a spinal cord injury and cannot walk straight or without a cane normally, has been using the device three times a week for the last month and is doing great. the computer actually powers one of his legs more than the other to give him a natural stride which he says is helping to relieve the strains his injury is causing to the rest of his body.

Bionic Suit cleared by FDA for home use

The below article by Bionics Research is a major step forward for individuals with spinal chord injuries.  It is also important for people living with a progressive neuro-muscular disorder like Kennedy's Disease.  The more of these units the hit the market, the lower the cost.  It also allows for even greater testing and generates interest in the technology.world for similar units that will support other uses.

Personal Exoskeleton System Cleared by FDA for Home Use

Revolutionary technology that allows individuals with Spinal Cord Injury, such as paraplegia, to stand & walk receives clearance for personal use in the U.S.

Marlborough, MA—June 26, 2014 — Exoskeleton leader ReWalk Robotics announced today that the U.S. Food and Drug Administration has cleared the company’s ReWalk Personal System for use at home and in the community. ReWalk is a wearable robotic exoskeleton that provides powered hip and knee motion to enable individuals with Spinal Cord Injury (SCI) to stand upright and walk. ReWalk, the only exoskeleton with FDA clearance via clinical studies and extensive performance testing for personal use, is now available throughout the United States.

The FDA has issued a marketing clearance for the ReWalk, which was granted via a rigorous de novo process that involved multiple clinical studies demonstrating safety and effectiveness of the technology.
“This revolutionary product will have an immediate, life-changing impact on individuals with spinal cord injuries,” said Larry Jasinski, CEO of ReWalk Robotics. “For the first time individuals with paraplegia will be able to take home this exoskeleton technology, use it every day and maximize on the physiological and psychological benefits we have observed in clinical trials,” he added. “This is truly the beginning of ‘ReWalking’ as a daily reality in the U.S.”
