Non-invasive stimulation device shows promise in treating spinal cord injuries
WILLOW SPRINGS, Ill. (WGN) — There has been an extraordinary step forward in the treatment of spinal cord injuries.
For the patients who come through the door of the Next Steps clinic in southwest suburban Willow Springs, it takes tremendous effort. But it's worth it.
'We are really living out our mission here at Next Steps, which was to provide access to technology at a community level,' physical therapist and clinic director Mary Jones said.
Bari Rubenstein has been living with quadriplegia for 14 years – the result of an infection and subsequent hematoma that damaged the nerves in her spine.
'I never thought in my lifetime I would get this opportunity,' she said.
It's access to a device called ARC-EX that's giving Rubenstein some hope.
'It is able to bridge an electrical gap and cover that injury so new pathways within the spinal cord can create movement,' Jones said.
Electrical nerve stimulation is not new, but the ARC-EX is non-invasive – it delivers pulses from electrodes placed on the skin that amplify weakened signals from the brain. The stimulation helps restore muscle activation below the site of injury, which is often blocked.
An electrode is placed above Rubenstein's injury and another is placed below.
'So the stimulation bridges that area of the injury,' Jones said.
Once the leds and electrodes are all connected, Jones starts the stimulation and gradually ramps it up. As the stimulation activates the muscles, clinic director Jones reinforces the movement.
'We pair that with retraining, learning how to re-move for those persons with spinal cord injury, and that device helps make that connection that was once lost with spinal cord injury,' she said.
'I have better breath support, which is huge because a lot of times people can't hear me, so I'm trying to amplify my voice more,' Rubenstein said.
'Even people with chronic injuries are seeing gains with this,' Jones said. 'People 14 years out, you think, 'At 14 years what is out there for me?' This device could be that device.'
At Next Steps, patient Trevor Hayden takes steps without the device. It's a significant struggle.
'It's so choppy because it's like three separate motions,' he said.

The 33-year-old, paralyzed in a truck accident eight years ago, travels nearly three hours twice a week so he can access the new stimulation system.
'The pulse that it delivers is almost you can feel it kind of spreading, and it's not just directed right where the pad placement is,' he said. 'This feeling of kind of waking things up in a way.'
The steps with the device are more fluid and take less effort.
'(It is) much easier. It just feels like everything is kind of pulled together,' Hayden said.
The care provided at Next Steps is a labor of love born from loss. Jon O'Connor was 30-years-old when he hit his head after jumping off a dock.
'He got paralyzed C4-C5. Very high level. All he had was use of his right bicep,' his father John O'Connor said.
But the injury did not deter his tenacity. In the years following his accident, Jon worked tirelessly to build a non-profit clinic that offered fellow patients the most promising treatments to improve movement and strength.
'Even though some things wouldn't benefit himself, he saw the value that it would have for others and fought for that,' his sister Kelly Heneghan said.
Now his family continues the fight. Jon passed away in 2013 – 12 years after his injury – due to the secondary effects of his paralysis.

'We really want to be able to give our patients the most technologically advanced equipment, and at that time and still to this day, a lot of those things are reserved for clinical trials,' said Heneghan.
Not at Next Steps, where technology like the Onward device is up and running for all those who may benefit.
'To me it feels like my muscles are waking up,' Rubenstein said. 'For a long time it was nothing.'
'I wish Jon could be here to see this. This is exactly what he would have fought for, and the fact that we have it now is really exciting for our patients,' Heneghan said.
'I get emotional about it because there are brilliant people, brilliant scientists out there coming up with these type of devices, and to see it come and change peoples' lives and being part of that is a really big gift,' Jones said.
An at-home unit is in the works. The device makers hope to have that available in 2026.

D-Day rally in Idaho protests proposed cuts to Veterans Affairs
James Peterson has Stage 4 cancer, likely caused by exposure to Agent Orange during the Vietnam War. He's in hospice now and uses on oxygen tank. But he wasn't going to miss a rally Friday afternoon in front of the Boise Veterans Affairs Medical Center. He was taking part in the Unite for Veterans rally in conjunction with a national rally held at the same time in Washington, D.C., to protest proposed cuts to the VA. 'I don't know what veterans are going to do if they keep screwing with things,' Peterson told me. 'We made a promise, they made a promise, and now they're breaking their promise,' he said as he broke down in tears. He said he's received excellent care at the Boise VA, which he said has saved his life twice, from pneumonia and sepsis, and is now providing care for his cancer. Earlier this year, it was revealed that as part of cuts by Elon Musk's so-called Department of Government Efficiency, the Department of Veterans Affairs was planning to cut 83,000 jobs, slashing employment by over 17% at the federal agency that provides health care for millions of veterans, according to an internal memo obtained by The Associated Press. The date for Friday's rally, June 6, is significant: It's the anniversary of D-Day, the day that Allied forces stormed the beaches at Normandy, France, marking the beginning of the end of World War II in Europe. About 70 people lined Fort Street in front of the Boise VA center, drawing honks and waves from most of the passersby. A couple of knuckleheads shouted 'Go Trump,' apparently in celebration of cutting funding for programs that help veterans. (A passing Tesla cybertruck drew a round of boos from the protesters.) Protesters held signs that read, 'Hands off VA,' 'Cut DOGE, Not VA,' 'Veterans fought for us, now we fight for them,' 'No King! Veteran, not loser' and 'Our vets are not suckers or losers.' Nancy Daniels, holding a sign that read 'Our vets deserve a fully staffed VA,' is an Air Force veteran who served seven years during the Vietnam War and spent 20 years working as a medical service worker at the Boise VA before retiring in 2023. 'This is a phenomenal center,' she told me. 'I am proud to be a veteran. It just breaks my heart to see what's happening.' She said Idaho's congressional delegation showed up several years ago to support the opening a women's wellness center and clinic at the Boise VA. 'They supported us, and now they're doing this,' she said. 'Shame on them.' Earlier this year, I interviewed one VA employee from Boise who was fired from his job in Washington, D.C., shortly after he had been hired. His job was to help connect veterans with services. These cuts are not going to fly with the American public, Jim Jones, former Idaho attorney general and state Supreme Court chief justice who helped to organize Friday's local rally, told me. Jones spent 401 days in a heavy artillery division in the Army in Vietnam. 'They've made plans for draconian cuts to the VA,' said Jones, who was wearing an Army uniform that he hadn't worn since August 1969. 'They want to get rid of 83,000 staffers, and it's just not going to work. It's a major betrayal of our veteran population, and I don't think the American people are willing to put up with it.' There is good news — sort of. Despite DOGE cuts, the House Appropriations Committee, of which U.S. Rep. Mike Simpson, R-Idaho, is a member, included an $83 billion increase in its fiscal 2026 VA spending bill to about $453 billion, according to That would be good news — if Congress approves it and if Trump doesn't arbitrarily cut it. That said, medical care would get only a 4% bump in the committee's approved budget, and the plan includes allowing veterans to see private doctors. Raymond O'Dell, of Boise, who is trying to form a Veterans for Peace chapter in Idaho, said he's worried about plans to privatize VA medical services. 'I just don't think the public truly understands what would be lost if we privatize the VA,' he said. 'Veterans are not where the cuts need to be made. We should find cuts elsewhere. We made a promise to our veterans.' For Peterson, that promise is sacrosanct. 'We signed a check,' he said, breaking down again, 'to put our lives on the line for the Constitution, and these nippleheads in Washington, D.C., who have never served or pretend that they served have no idea what it is they have to do. They promised us their support, and they need to take care of those who have served this country.'

Netflix documentary sheds new light on Tylenol murders of 1982
CHICAGO (WGN) – In 1982, seven Chicagoland residents died out of the blue after taking Tylenol capsules that were laced with cyanide. Decades later, investigators are still baffled. Now, a new Netflix documentary, 'Cold Case: The Tylenol Murders,' looks to unpack the cold case and shine a new light on the investigation. On Sept. 28, 1982, 12-year-old Mary Kellerman from Elk Grove Village was hospitalized after taking one Extra-Strength Tylenol capsule. She died the following day. That same day (Sept. 29, 1982), 27-year-old postal worker Adam Janus of Arlington Heights died of what was initially believed to have been a heart attack, but officials later attributed his death to cyanide poisoning. His brother Stanley, 27, and sister-in-law Theresa, 19, both of Lisle went to Adam's home to be with loved ones after Adam's death when they experienced intense headaches. They each took Extra-Strength Tylenol capsules from the same bottle Adam used earlier in the day to soothe their symptoms. 40 years after Tylenol Murders terrified nation, new information shows case is still being investigated Stanley died later that day, while Theresa died two days later, according to authorities. Over the next few days, 35-year-old Mary McFarland of Elmhurst, 35-year-old Paula Prince of Chicago, and 27-year-old Mary Weiner of Winfield all died after taking Tylenol capsules laced with cyanide. At the time, Tylenol was the most popular, best-selling non-prescription pain reliever in the United States. One reason was because the capsules were reportedly gelatin-laced, making them slick and easy to swallow. In early October of 1982, investigators determined the seven victims all swallowed a Tylenol capsule laced with a lethal dose of cyanide. At that time, Tylenol was made by McNeil Consumer Products, a subsidiary of Johnson & Johnson. As investigators attributed the deaths to Tylenol capsules laced with cyanide, McNeil Consumer Products issued a mass warning and immediately called for a monumental recall of over 31 million bottles of Tylenol in circulation. Investigators reportedly found tainted capsules in some grocery stores and pharmacies in Chicagoland, but those capsules had not yet been sold or consumed. McNeil Consumer Products and Johnson & Johnson offered replacement capsules to anyone who turned in pills they already purchased and a reward for anyone with information leading to the arrest of the person(s) involved in the poisoning. As the investigation went on, Johnson & Johnson determined the cyanide lacing happened after bottles of Tylenol left their factory. Police thought someone had to have gone to the grocery store and/or pharmacy, taken the bottles off the shelves, laced them with cyanide and then went back to the store and put the laced bottles back on the shelves where the unknowing victims bought them. Arrests made in decades-old Kenosha County cold case No. No one has ever been formally charged in connection with the deaths, but one man peaked the interest and suspicion of investigators: James Lewis. After a nationwide manhunt, authorities arrested Lewis in 1982. He served over 12 years in prison for sending an extortion letter to Johnson & Johnson in which he demanded $1 million to 'stop the killing.' Following his arrest, Lewis reportedly gave investigators a very detailed explanation as to how the person responsible for the murders might have operated before admitting to having written and sent to extortion letter to Johnson & Johnson. Lewis claimed he never planned on getting any money by sending the letter and instead wanted to shine a bad light on his wife's former employer. While serving his prison sentence, he told the Associated Press the detailed explanation as to how the suspect might have operated was just an assumption about the suspect's actions. He called the suspect 'a heinous, cold-blooded killer, a cruel monster.' Police and federal investigators later determined Lewis was living in New York City at the time of the poisonings, although he briefly lived in Chicago in the early 1980s. Lewis was released from prison in 1995 and he and his wife then moved to Massachusetts. Illinois authorities reopened the investigation in 2009, prompting FBI investigators to go to Lewis' Massachusetts home where they took his computer and other belongings. Reports said Lewis provided DNA samples to the FBI in 2010. He died on July 9, 2023, at the age of 76. Netflix announces new subtitle option: How it works In 1983, Congress passed 'the Tylenol Bill,' which made it a federal crime to tamper with consumer products. Then in 1989, the Food and Drug Administration put forth federal guidelines for manufacturers to follow to make consumer products tamper-proof.

Non-profit fears for future of blindness research if Donald Trump's budget passes
LAKE COUNTY, Ill. (WGN) — Proposed federal funding cuts are hitting home in Lake County, especially when it comes to the blind. The Foundation Fighting Blindness, a Maryland-based non-profit organization who organizes the Chicago Vision Walk, fears clinical trials and promising new treatments for blindness and retinal disease will be frozen or canceled if President Donald Trump's 'Big, Beautiful Bill' passes into law. 'Six years old was when I got the diagnosis,' Rich Idstein said. 'It's tough.' Idstein is a legally blind man who works at Ace Hardware in Libertyville. He suffers from Retinitis Pigmentosa, a blinding retinal disease with no cure. Idstein and his two brothers all suffer from the same disease, which gets progressively worse with age. At the age of 52, Idstein figures he has five-to-ten years left before he's completely blind, but he's hoping clinical trials through the National Institutes of Health will lead to new treatments. 'We are driving research for therapies. They're called gene therapies that can replace or fix that code,' said Ben Shaberman, Vice President of Communications for the Foundation Fighting Blindness (FFB). 'So, the cells in the retina work correctly, and vision can be saved or restored.' The problem is, under Trump's proposed budget, the NIH is facing a potential 40% funding cut to medical research, which would directly impact the dollars going toward the clinical trials that Idstein hopes can help cure the disease that's plagued he and his brothers. The FFB has raised nearly $1 billion over the past five decades for eye and vision research, but its mission could be severely impacted if Congress doesn't act.
