No More “Fear of Falling” with the ZeroG Gait and Balance System

Source: Spokesman-Review

After a July 23 rollover accident, Cameron Tweedy received a grim outlook on ever walking again. Along with lower body numbness, he had suffered five fractures in his spine and a crushed ankle.

“They told me I had less than 1% chance of minimal function in my legs,” said Tweedy, 21, a Spokane resident. “I had less than 1% chance of twitching my toes, essentially. I didn’t like that.”  He described surgery to repair his spine with pins, rods and a thin metal bar. With therapy, Tweedy now can walk, mostly using crutches. Since early January, he credits a much faster pace to the help of a new device at St. Luke’s Rehabilitation Institute.

Called the ZeroG Gait and Balance System, the robotic body-weight support equipment helps people learn to walk again without fear of falling. The system simulates a reduced-gravity environment. The ZeroG system is expected to help about 1,000 patients a year who have spinal cord and brain injuries, stroke symptoms, multiple sclerosis diagnosis, Parkinson’s disease and lower extremity amputations, St. Luke’s said in a news release.

The device is attached to a motorized trolley along a U-shaped, ceiling-mounted track in a large therapy room. A rope suspends from the ZeroG that is hooked to a harness worn by the patient. As the ZeroG was installed in late December, Tweedy was transitioning from a walker to crutches and had reached about 400 to 600 steps per session. Within a week or two of using the ZeroG, he said it helped him exceed 1,500 steps in one session.

“It’s really hard to go from not walking, and using a walker where you can put all your weight down, to going to crutches,” he said.  “I struggled more with walking with that fear of falling, especially with not being able to feel all the lower half of my body. It built my confidence back up. When I started using the ZeroG, that’s when my progression started getting better because the fear of falling went away.”

The robotic device has a sensor as it tracks movements from above, and information is linked to a nearby computer. Therapists also can use a smartphone for monitoring, and software collects data that tracks a patient’s progress and a session’s results. Parameters are set so that the device catches a person before they fall but can allow for some range of motion such as climbing steps. As a patient’s therapy progresses, a wider range can be practiced, such as going from standing to a seated position.

 

Neurophysical therapist Sarah Gross and Jake Allstot, assistant manager of rehabilitation at St. Luke’s, helped Tweedy go through a recent session. Gross said Tweedy uses the ZeroG once a week in addition to swimming for outpatient therapy.

Allstot said the ZeroG is designed to eliminate the fear of falls because it prevents those from happening, but patients can still feel any loss of balance and the body adjustments needed to compensate if they sense a fall.

“Since we started using it in January, we’ve worked with 32 patients and prevented 250 falls,” Allstot said. “It allows freedom of movement, and it does that with safety at the forefront.  “This device allows a patient to really feel his own loss of balance, feel his own weight and do his own performance, but not by compromising safety.”  That takes a caregiver’s focus away from watching for falls and instead on providing better therapy treatments, Allstot said. “You can program a fall distance. You can set perhaps 4 inches of fall, or you can set it to where it’s a velocity where it will detect if a patient drops really fast,” he said. “It will stop and correct that fall.”

In earlier therapy sessions, Tweedy had used another piece of equipment at St. Luke’s, the Lokomat, that’s a robotic exoskeleton treadmill. The Lokomat helped him to walk up to nearly 400 steps per session this past fall.

For the recent session, Allstot put the ZeroG’s body harness on Tweedy. The harness attaches to a bar and a rope hovering above a patient’s shoulders. The harness also is secured around the waist, with straps down the thighs and attached around the leg above the knees. During the recent session, Tweedy practiced walking with the use of both crutches. Later, he practiced going over a step, and then walking with one crutch to prepare for eventual use of a cane.

“The way I have it set now is if he drops at certain speed, as soon as he hits that speed, it will catch him,” Allstot said. “The reason we could go over that step is he didn’t exceed a certain velocity.”  “The sensor detects how much rope is coming out and how fast. He can go all the way to the ground, and the machine will adapt for that need or for him to sit. It also counts total steps. We can change to a small movement, so if you have a small buckle, it will trigger a response to protect the patient.”

Allstot also demonstrated how the device can help patients practice adjusting their weight and balance in response to someone bumping into them. Tweedy had to shift his balance and at one point put a foot out to catch himself.   “You can do a response to simulate a forced pull on him,” Allstot said. “He has to stay balanced. It’s practical if someone in the community bumps into him, and that can happen. He’s practiced for that.”

St. Luke’s also described the ZeroG, which costs $260,000 for equipment and installation, as the only device of its kind in the Inland Northwest. Providence Health Care Foundation provided funds for the system, with major contributors including the Craig H. Neilsen Foundation and the M.J. Murdock Charitable Trust.

 

Learning to Walk again at Methodist Outpatient Rehab

Source: Meridianstar

Accustomed to running around on the softball field, Northeast Lauderdale alumna Alixus Hearn decided she wasn’t going to be sitting down for the rest of her life.

On Oct. 2, 2017, Hearn was involved in a car wreck that ejected her from her vehicle and left her paralyzed from the waist down due to her fourth and fifth thoracic vertebra being bruised and twisted. Initially, doctors told her she may never walk again, but Hearn opted for a vigorous rehab program at Methodist Rehabilitation Center in Jackson.

“Sitting down for a long period of time, I just wasn’t with that,” Hearn explained. “Having my mom and dad with me, they kept the positive energy around me. I just put everything in and went head first. I wasn’t sitting down until I got better.”

It began with baby steps last November, followed by using a walker to help her. Eventually, she ditched the walker for a cane, which she used from February until May. Now, Hearn no longer uses the cane to walk.

“It feels amazing,” Hearn said. “I can’t really explain it. It’s just been amazing. I don’t have to depend on anything to help me walk.”

Methodist offered Hearn rehab technology like the ZeroG Gait and Balance System, a device connected to an overhead track that harnessed Hearn upright, allowing her to do a wide range of motion activities while preventing her from falling. Originally, she went to therapy three times a week, but now her sessions have been reduced to once a week.

Having access to high-tech rehab equipment made a big difference in Hearn learning to walk again, and she said she’s grateful to live in a time where such technology is at her disposal.

“I don’t think Meridian gets that many spinal injury patients,” Hearn said. “They probably wouldn’t know what to do. I tried every piece of equipment (Methodist) had, and it helped a lot. I’m grateful for that.”

Emotional support proved just as important as physical support, and that began with Hearn’s parents, Allison Hearn and Demitrius Robinson.

“They did every single thing they could to keep me motivated and pumped,” Hearn said. “Both of them were my motivators. They did a good job with keeping my spirits up.”

That emotional support extended to her Lady Trojan teammates, who adopted the slogan “13 strong” in honor of Hearn, who wore No. 13 for Northeast Lauderdale.

“That meant everything to me,” Hearn said. “It showed me how much they cared and loved me.”

Being a softball player also helped in her rehab from a physical standpoint.

“Even my therapist said that since I played sports, I had a lot of muscle, and that was good,” Hearn explained. “In my sessions, there were some spots where I was stronger just because I played softball and had all that extra weight.”

Now a student at Meridian Community College, Hearn plans to transfer to Mississippi State and earn a degree in athletic training. Having grown up playing sports, Hearn said she would love to continue being around athletics as a trainer.

“At first, I just played for fun so I wouldn’t get bored, but as I gradually got into it, I just fell in love with the game even more, being out there and doing what I do best,” Hearn said.

 

Community Hospital in Munster offers ZeroG

Amy Peters and Julie Gaski are taking steps to heal and recover after illness left them unable to walk by themselves. With the help of new technology at Community Hospital in Munster, they have new motivation and hope.

The ZeroG Gait and Balance System, the first of its kind in Northwest Indiana, is a robotic, body-weight support system. Patients wear a specialized harness that connects to the ZeroG robot as it supports and tracks their movements from above. ZeroG helps the patient practice walking, complete balance exercises and work on position changes such as sitting to standing. The “reduced gravity” environment is a feature to support balance while preventing falls.

“ZeroG gives our patients the safety and confidence to practice functional, real-world balance and walking activities,” said Amy Castillo, director of therapy services at Community Hospital. “We believe the use of ZeroG technology will help our patients accelerate and maximize recovery.”

Peters, of Munster and a Times employee, experienced difficulty walking as the result of a tumor that was pressing on her spinal cord. After chemotherapy, she initially was only able to walk with the assistance of a walker. Once her physical therapist added the ZeroG sessions three times a week, she was able to stand on her own.

“Using a walker is just not the same,” Peters said. “The ZeroG has restored my confidence in walking.”

Gaski, a resident of Crown Point, agrees. For two years following a stroke that rendered her left hand and foot immobile, she couldn’t walk and had an overwhelming fear of falling.

“The ZeroG gives your body a different feeling of ‘I can do this,’” Gaski said. “It’s amazing to stand on my own again after two years. It’s a wonderful thing.”

ZeroG can support up to 450 pounds and a variety of diagnoses, including stroke, traumatic brain injury, spinal cord injury, amputation, cerebral palsy and other orthopedic and neurological conditions. The therapist secures the individual into a comfortable harness, attaches it to the ZeroG robot and therapy can begin. The amount of support is customized for each person depending upon the level of their ability and can be increased or decreased with the touch of a remote button.

Support can be set to offload the person’s weight by up to 200 pounds, making them feel lighter in a “reduced gravity” environment. This allows them to undergo therapy at higher intensity levels sooner after injury or illness. As the individual progresses, the support can be decreased so the person does more under their own capabilities.

“For patients’ recovering from a stroke, like Julie, who cannot feel or have impaired awareness of where their foot and leg are when standing or walking, their perception and safety of daily mobility may be altered or compromised,” said Jacob Virgo, a clinical specialist in the hospital’s physical therapy department.

“The ZeroG allows for more intensive and task-specific training that may not be feasible outside of the support system. It gives therapists and patients the confidence and means to push the limits of what is possible, and allows the patient to progress to that next level of independence and safety.”

TRiP Released for ZeroG

Source: PRWeb

Aretech, LLC, an advanced rehabilitation technology leader, announced the release of TRiP for the ZeroG Gait and Balance System, which allows therapists to apply unexpected external perturbations to their patients in order to teach them how to recover from a loss of balance. TRiP (Training Responses in Postural Rehabilitation) was developed in collaboration with Drs. Fay Horak and Laurie King at the Balance Disorders Laboratory at Oregon Health and Science University (OHSU).

Inadequate stepping responses in the elderly and those with neurological impairments contribute to a loss of balance and falls. With TRiP, ZeroG becomes the first and only technology which can apply measurable and controlled perturbations in a safe and consistent manner to patients while they are standing or ambulating. Therapists can personalize the strength of the perturbation and the direction in which the ZeroG robot will perturb the patient. This gives them the ability to modify and challenge patients with balance disorders.

“ZeroG TRiP is a revolutionary new breakthrough in approaching balance training and fall prevention. Balance recovery involving rapid compensatory stepping is essential to prevent falling. However, learning these techniques requires eliciting a loss of balance which is not typically practiced in rehabilitation due to the safety concerns of falling,” said Joe Hidler, PhD, CEO of Aretech. “Now with TRiP, because they are connected to ZeroG, there is no risk of falling as they practice recovering from a loss of balance. Therapists can safely simulate slips and trips during walking, turning, and stepping backwards within the safe environment of ZeroG.”

TRiP is completely unlike other balance training methods because ZeroG can be used to simulate real-world situations while the person is dynamically moving. In addition, the patient can be completely taken by surprise by not knowing when or in which direction the therapist will perturb them. Other methods such as balance platforms are not realistic scenarios as most falls occur during walking and turning. With platforms, the patient routinely has their feet firmly planted anticipating the disturbance.

“Laboratory studies have shown that postural stepping responses can be improved with practice,” said Fay Horak, PhD, PT, Professor of Neurology, School of Medicine, Oregon Health and Science University. “Now it is possible for physical therapists to implement this type of training safely with their patients.”

TRiP was designed to be an easy-to-use application on the ZeroG touchscreen and wireless remote. This empowers therapists to quickly choose the strength and direction of a perturbation on the fly so each session can be tailored to each individual. Dr. Hidler anticipates TRiP will be an important tool in a fall prevention program. “By learning the skills practiced with ZeroG TRiP, patients in their daily lives will be better prepared to recognize how to recover from a loss of balance at home and in the community. The hope is that this, in turn, will decrease the likelihood of a fall.”

About ZeroG TRiP

TRiP (Training Responses in Postural Rehabilitation) is a patent pending software algorithm for the ZeroG Gait and Balance System. TRiP allows therapists to apply controlled and measurable perturbations to patients while ambulating or during stationary activities. The framework for ZeroG TRiP is based on the scientific findings from the Balance Disorders Laboratory at OHSU over the last ten years.

ZeroG Used to Push Boundaries at Special Tree NeuroCare Center

Source: WXYZ Detroit

Cutting-edge new technology making its debut in southeast Michigan could be life-changing for those with brain and spinal cord injuries.

The robotic “ZeroG” is helping patients at Special Tree in Romulus.

Sloan Hogan was driving down the street when a vehicle came out of his driveway right out into the middle of the street, hitting him. He was paralyzed from the armpits all the way to the bottom of his feet.

At Special Tree’s Neuro-rehabilitation center, he’s now doing something he couldn’t do a month ago thanks to ZeroG. He’s walking.

The ZeroG Gait and Balance System by Aretech, is a robotic body-weight support system that enables those recovering from brain injuries to engage in high-intensity rehab much sooner in the recovery process – which studies show lead to much better patient outcomes.

ZeroG gives patients like Hogan the confidence to push his boundaries without fear of falling and a feeling of independence.

Instead of their movement being corrected by a therapist, ZeroG helps patients correct themselves which speeds recovery.

Emergency room physician, Matthew Wetschler was body surfing when a wave sent him head first into the ocean floor. He was found floating in the water with a broken neck and without a pulse. He was given CPR on the beach, and was rushed to the hospital without the ability to move his arms or legs. Three hours later, he was in a pioneering “ultra early surgery” and was able to slightly move his left hand and leg the next day.
Just over a week later, Wetschler was transferred to Santa Clara Valley Medical Center’s inpatient rehabilitation unit. He used Aretech’s ZeroG Gait and Balance System to practice getting to standing, walking, lunges, kicking a soccer ball, and tossing and catching inflatable balls.
Because of all those involved in his recovery, and by using ZeroG to safely practice intensive therapy, Matthew Wetschler’s pace of recovery has been uncharacteristically rapid.

Aretech Unveils New ZeroG Gait and Balance System

Aretech, LLC, an advanced rehabilitation technology leader, announced the release of Version 3 of the ZeroG Gait and Balance System at the American Physical Therapy Association’s Combined Sections Meeting (APTA-CSM) in San Antonio, TX. The new ZeroG is the most sophisticated robotic body-weight support system in the world. The system has been redesigned with more features, more versatility, and even higher performance. With the WaveLink WiFi Guardian, ZeroG becomes the first and only completely wireless system in its class not dependent solely on Wi-Fi connectivity.

“The new ZeroG truly encompasses over a decade of experience working hand in hand with physical therapists around the world to deliver the most advanced rehabilitation technology for treating gait and balance disorders,” said Joe Hidler, CEO of Aretech and inventor of the ZeroG Gait and Balance System. “Our commitment to patient safety is reflected in numerous new safety features, including the WaveLink communication protocol. This provides therapists an alternate method of controlling ZeroG independent of a Wi-Fi signal.” Dr. Hidler also believes the new features of ZeroG will help deliver a premium rehabilitation experience. “One of the new features we are most excited about is the new dynamic fall recovery with ActiveAssist, which intelligently adapts the dynamic body-weight support after a fall to aid those patients who may need assistance regaining control.”

At APTA-CSM, therapists had the opportunity to try the new ZeroG. “Therapists really appreciated our new fall cushioning technology. This softens the impact for the patient when ZeroG catches a fall, making for a much more comfortable experience,” said Don Gronachan, Aretech’s Vice President of Sales and Marketing.

ZeroG Version 3 Release at APTA-CSM 2017

The Most Sophisticated ZeroG Ever

Originally launched in 2008, ZeroG gives therapists the opportunity to safely treat a broad range of patient populations with dynamic body-weight support in functional activities such as overground walking, sit-to-stand, getting off the floor and stairs. Building upon innovations pioneered by Aretech, ZeroG Version 3 represents the biggest redesign in years. The system now has the capacity to support up to a 450-pound patient. Because ZeroG may be used to raise a patient to standing, one therapist can train heavy patients without the risk of falling.

The dynamic body-weight support of ZeroG is the fastest and most precise available, accurately tracking vertical movements at over 26 inches per second, which is twice as fast as similar systems on the market. This provides patients a stable environment with constant body-weight support even when getting to standing from a chair or the floor. Using ZeroG Kinetics, therapists can choose from various balance training programs using real-time biofeedback to treat their patients in anticipatory balance activities. And for those who have two ZeroG robotic trolleys on the same track, ZeroG has the new Stealth Detection feature, which acts as invisible bumpers to propel the second robot out of the way when not in use for a truly infinite track.

“Aretech is proud to continue to advance the field of rehabilitation forward with innovative, first-to-market features which have never been seen before,” said Hidler. “We’ve been able to take our experience and create the most sophisticated rehabilitation system on the market that gives therapists and patients the best opportunity to improve outcomes.”

How ZeroG is Used with Marianjoy Patients

Source Video: Marianjoy

Vanessa Flaherty, PT, DPT, a physical therapist at Marianjoy Rehabilitation Hospital in Wheaton, IL, shows how ZeroG helps them safely perform gait retraining with their patients.

 

ZeroG can help those who are recovering from neuromuscular disorders such as stroke, traumatic brain injury and incomplete spinal cord injury or other orthopedic conditions. ZeroG enables Marianjoy therapists to provide the patients with task-specific practice. This means, that the patient is able to practice the entire task of walking as a whole without breaking up the movement into individual components.

 

ZeroG differs from conventional harness systems. Traditional systems catch the patient immediately once the loss of balance is detected in order to prevent a fall. ZeroG, however, allows the therapist to set the amount of distance before the catch mechanism is employed. Not only does this help the patient to relearn how to control and recover from a stumble or fall, it also retrains the brain on the proper way to react and correct for a loss of balance. Because ZeroG provides the opportunity to make errors in a safe environment, the patient is better able to carry over these skills to real-world situations.

 

zerog-woodway

 

Another benefit of using ZeroG, is that it allows for increased repetition and practice of the task of walking. ZeroG is also integrated with a Woodway split-belt treadmill. The treadmill allows the therapist to vary the speed of the patients gait as well as isolate working on one leg or the other to help improve the affected leg’s swing time and challenge it’s stability.

Because the system can be set to support any amount of the client’s body-weight, most clients are able to walk for a longer time period and often at a faster pace without fatiguing as quickly.

 

Recent neuroplasticity studies have shown repetition and task-specific practice like this is essential for the recovery of functional mobility as well as the cortical recovery in the brain itself. The ZeroG system can also be used while performing balance training, floor transfers and while teaching patients how to overcome other barriers such as stairs, curves and other obstacles they may encounter at home and within their community.
