Michel Roccati, by his own account, is on his third and final life. He was an equal-aged man riding his bike around Italy in his first life. He was paralyzed from the waist down after a 2017 accident in the hills near Turin. In the third, Michel Roccati is currently working out in his Turin house gym. He can use a walker to get around and can climb stairs to reach a friend in a condominium on the second floor. He says that his life is now “utterly different” than it was before.
Roccati, 31 years old, is one of three men who received experimental spinal wire stimulators as part of a medical study. The results were shockingly successful, just as Roccati had hoped. He says, “I recollected in my mind how I was at the end of the mission.” “I saw myself standing and walking. It was exactly what I expected at the end.”
The February edition of Nature Medicine describes the technology used by Roccati and others. It is an array of electrodes implanted below the site of injury. The system uses electrical indicators to replace the brain’s missing indicators, allowing the muscles to move in ways that allow stepping, climbing stairs, and even doing squats in the gym.
Many people with spinal cord injuries have to deal with issues that aren’t so obvious as paralysis. People suffering from paralysis face many challenges in their daily lives, including low blood pressure, sexual dysfunction, breathing difficulties, and the controlling of arms, bladder, and bowel movements. John Chernesky, a person with a spinal injury, says that these are the most important issues for people affected by spinal cord injuries. He is a member of the non-profit Praxis Spinal Twine Society in Vancouver. There, he ensures that the voices and priorities of those with spinal cord injuries are heard and addressed in research.
Researchers hope to determine the language of the spinal cord and be able to fill in disregarded commands, thus bridging any gaps. This work could help to address many of the issues that sufferers face.
Kim Anderson Erisman, a neuroscientist at MetroHealth Medical Center in Cleveland and Case Western Reserve University is stating that “the field of research is changing…embracing all these different aspects.” Early medical trials have already begun to address the less obvious problems that arise from spinal cord injuries. Roccati was assisted by the same scientists who confirmed that similar spinal cord stimulation reduced a person’s low blood pressure. Other researchers are studying stimulation to improve bladder and bowel functionality. However, there are more targeted actions that can be done. It is becoming easier to understand how to use this knowledge to influence the nerves in the spinal cord.
Anderson Erisman, a victim of a spinal cord injury, believes that shifting is the best method for analysis. She says that scientists are familiar with the basic issues surrounding spinal cord injuries. “But that’s not the same as living someday with a spinal injury.” “Involving people with spinal injuries in research, as partners and collaborators rather than just topics, is pushing the pace of analysis further and faster. She says that such collaboration will only make your program more powerful.”
These efforts are still in their early stages. The majority of people who could benefit from stimulators do not have access to them. These intense medical trials have been completed by a small number of people. It is not clear how the results will hold up in larger trials that involve a greater number of volunteers. It is also unclear how accessible this expertise will be to those who actually need it. The analysis requires large groups of consultants in big cities. Patients will need to undergo surgery and may require months of training before the body responds.
However, spinal cord stimulation has many benefits beyond the potential for spinal cord injuries. The stimulation of the spinal cord’s nerves could help people with strokes, Parkinson’s disease, cerebral palsy, and other issues that blur the lines between the mind-body. V. Reggie Edgerton is an integrative biologist at the College of Southern California’s Neurorestoration Center. He says that in the beginning “hardly anyone wanted to comprehend these [improvements] were taking place.”
A critical spinal cord injury was not a death sentence, but it happened a long time ago. Chernesky explains that prior to World War II, the average life expectancy for someone with a spinal injury was counted in terms of days or weeks. If the injury didn’t cause death immediately, an individual would usually succumb to respiratory disease or poisoning from a bladder infection. He said, “If you survived six months, that was amazing.”
The spinal cord links the mind and body. The mind sends alerts to the leg muscles to contract in preparation for a step. Blood vessels expand and the bladder control urinary flow until a toilet is within reach. The body sends alerts to the mind that can cause sensations such as movement, pain, and physical sensations. These indicators can be blocked if the spinal cord becomes damaged, which on average impacts 18,000 people in the US alone each year.
Researchers have long dreamed about repairing the injury using stem cells or other development elements. This could allow nerve cells to grow within the scar. Partly, this unintended statement led to the idea of using electrical energy to stimulate nerves below the site of an injury. In the mid-70s, spinal cord stimulation was being tested as a treatment for chronic
