EvoWalk stimulates nerves to enable muscle-impaired men and women stroll

Health startup Evolution Devices has designed an AI-based platform known as EvoWalk that stimulates nerves to enable muscle-impaired men and women stroll once more.

The platform blends remote physical therapy with connected smart stimulation devices to enable men and women such as cerebral palsy patients or stroke victims to rehabilitate and commence walking once more.

The business is launching a pilot system today to rehabilitate men and women living with neurologically based partial walking paralysis. It is also raising funds through a crowdfunding system.


Pierluigi Mantovani, CEO of Evolution Devices, mentioned in an interview with VentureBeat that he began working on the platform in 2017 as portion of an work to enable his father deal with the effects of a number of sclerosis.

After his father was diagnosed with MS, he struggled to stroll and he suffered some falls mainly because he dragged his foot although walking. Mantovani was at the University of California at San Francisco undertaking work on neurostimulation, or electrical stimulation of nerves. His group constructed a initially prototype and have spent years refining it.

“My dad has multiple sclerosis. He developed a walking problem pretty shortly after he had MS,” Mantovani mentioned. “So my cofounders and I ended up building our first prototype to help him pick up his foot while he walks so that he would stop tripping.”

Mantovani began working on a virtual physical therapy platform paired with an AI-informed nerve stimulation wearable known as the EvoWalk.

“We have a vision of having a more data-driven approach to physical therapy and rehabilitation,” Mantovani mentioned. “We started helping people specifically with neurologic impairments, like my dad has, but also for those who had strokes or spinal cord injuries.”

People who’ve skilled neurological circumstances such as strokes, MS, or Parkinson’s have a tendency to drag their impacted foot, but the EvoWalk makes use of machine studying to bypass the nerve and lift the foot at just the proper time to enable customers steer clear of falls and stroll more freely. Machine studying assists to discover the distinctive walking designs of men and women and adjusts the stimulation of the nerves with electrical energy.

The aim is to enable patients reclaim their lost instinctual movement.

Evolution Devices is initially focused on rehabilitating foot drop, an impairment exactly where a particular person is unable to lift their foot due to muscle weakness or nerve harm and which often causes falls. Mantovani believes there are about 4 million men and women with the dilemma.

“There are over 36 million people who fall at least once a year, and it’s costing the U.S. health system about $15 billion,” he mentioned.

Foot drop commonly outcomes from a stroke or MS. The EvoWalk remote therapy platform permits these patients to meet with physical therapists (PTs) practically, delivering them with a customized and extensive rehab system to enable them strengthen their mobility.

Evolution Devices is at the moment conducting a pilot of the EvoWalk Platform via Lisa Donahue, the company’s director of clinical services and a neuro physical therapist. In addition, researchers at the University of California at San Francisco are operating an EvoWalk clinical study.

Earlier pilot research of the EvoWalk Platform revealed that patients skilled up to a tenfold enhance in their walking activity and enhanced their walking speed in as small as eight weeks.

With the EvoWalk Platform, a patient is matched with a certified neurologic PT who assesses them remotely through a safe, HIPAA-compliant video platform.

The patient receives the EvoWalk device and downloads the patient app. Dedicated PTs train the patient on the EvoWalk and create a customized therapy system that evolves as their rehab progresses.

While wearing the EvoWalk device, the patient walks more freely as it delivers customized stimulation that lifts the patient’s foot at precisely the proper instances. Mobility information is automatically collected and shared with the patient and therapist and is used to refine their rehab therapy.

“Since we are collecting this data while they are wearing it, we can measure how much they’re improving, like how much a knee is bending,” Mantovani mentioned. “Over time, we can show their speed is getting better. We have a patient-facing app where patients can see their data.”

The EvoWalk device

Patients put on the EvoWalk device about the leg just beneath the knee. It delivers functional electrical
stimulation (FES) therapy to enable patients to choose up their foot and stroll more smoothly. By applying electrical stimulation to the reduce leg, EvoWalk acts as an artificial nerve that bypasses the non-functioning nerve accountable for lifting the foot and toes.

The device’s constructed-in sensors feed genuine-time motion information to AI algorithms and provide actionable metrics via connected patient and clinician mobile apps, driving patient engagement.

The patient app empowers patients by generating it straightforward to monitor each day progress of important metrics, although the clinician app delivers more detailed insights that allow PTs to remotely assess and refine their tailored rehab interventions.

One early EvoWalk user, a hemiplegic stroke survivor with foot drop, completed a 5K stroll in just more than an hour, shattering his aim of 90 minutes for finishing the race.

Evolution Devices has raised more than $1 million in funding from notable investors which includes the Alchemist Accelerator and Edge Systems founder Bill Cohen.

In addition, the business has won grants from such organizations as the Toyota Mobility Foundation, Bristol Myers Squibb and Lyfebulb, the National Science Foundation, and the National Institutes of Health.

“The device tracks people’s movement over time. So they wear it every day,” Mantovani mentioned. “It works as a therapeutic because of the stimulation. So people want to wear it. And then we get really detailed data, which helps us know how to move forward with physical therapy.”

The company’s aim is to launch in the second quarter of next year, but to do that the device will need to have clearance from the U.S. Food and Drug Administration as a physical therapy platform.

Mantovani’s father is nonetheless utilizing the device.

“He uses it pretty much every day. And every time we have a new version, he’s the first person to test it, which is nice because he can break it first before we give it to anyone else,” Mantovani mentioned. “This is one of our hardest problems, and it really helps to have a physical therapist help someone like my dad who has a progressive version of multiple sclerosis. This can help slow the progression.”
