Strokes often have a devastating impact on hands function. Now, Stanford researchers are collaborating on a vibrating glove that could improve hand function after a stroke.

The most obvious sign someone has survived a  is usually some trouble speaking or walking. But another challenge may have an even greater impact on someone’s daily life: Often, stroke survivors lose sensation and muscle control in one arm and hand, making it difficult to dress and feed themselves or handle everyday objects such as a toothbrush or door handle.

Now, researchers at Stanford are working on a novel therapy that could help more stroke survivors regain the ability to control their arms and hands—a vibrating glove that gently stimulates the wearer’s hand for several hours a day.

Caitlyn Seim, Ph.D., a postdoctoral scholar at Stanford, began the project as a  in human-centered computing at Georgia Tech in the hope that the glove’s stimulation could have some of the same impact as more traditional exercise programs. After developing a prototype, she approached Stanford colleagues Maarten Lansberg, MD, Ph.D., an associate professor of neurology, and Allison Okamura, Ph.D., a professor of mechanical engineering, in order to expand her efforts. With help from a Neuroscience:Translate grant from the Wu Tsai Neurosciences Institute at Stanford, the trio are working to improve on their prototype glove and bring the device closer to clinical testing.

“The concept behind it is that users wear the glove for a few hours each day during normal —going to the supermarket or reading a book at home,” Seim said. “We are hoping that we can discover something that really helps stroke survivors.”

Reaching for new stroke treatments

Seim, Lansberg and Okamura’s goal is a tall order. Despite some individual success stories, the reality is that most stroke patients struggle to regain the ability to speak, move around and take good care of themselves.

“Stroke can affect patients in many ways, including causing problems with arm function, gait, vision, speech and cognition,” Lansberg said. Yet despite decades of research, “there are essentially no treatments that have been proven to help stroke patients recover these functions,” he added.

It was in that context that the three researchers independently started thinking about what they could do to improve the lives of people who have survived strokes. As the  in the bunch, Lansberg had already been treating stroke patients for years and has helped lead the Stanford Stroke Collaborative Action Network, or SCAN, another project of the Wu Tsai Neurosciences Institute. Okamura, meanwhile, has focused much of her research on haptic, or touch-based, devices, and in the last few years her lab has spent more and more time thinking about how to use those devices to help stroke survivors.

“Rehabilitation engineering provides a unique opportunity for me to work directly with the patients who are affected by our research,” Okamura said. “The potential to translate the kind of technology relatively quickly to a commercial product that can reach a large number of  in need of therapy is also very exciting.”

For her part, Seim’s interest in stroke stems from an interest in wearable computing devices. Yet rather than build more virtual-reality goggles and smartwatches, Seim said she wants to apply wearable computing to the areas of health and accessibility—”areas which have some of the most compelling problems to me.”

Growing a new idea

With that ambition in mind, Seim built a vibrating glove prototype that she hoped would stimulate nerves and improve both sensation and function in stroke survivors’ hands and arms. After collecting some promising initial data, Seim reached out to the Stanford team.

“Stanford has SCAN and StrokeNet, along with a community of interdisciplinary engineering and computing research, so I reached out to Maarten, and he was very supportive,” Seim said.

Now, Seim, Lansberg and Okamura are revising the glove’s design to improve its function and to add elements for comfort and accessibility. Then, they’ll begin a new round of clinical tests at Stanford.

Long term, the hope is to build something that helps stroke survivors recover some of the functions they have lost in their hands and arms. And if initial tests work out, Lansberg said, it’s possible the same basic idea could be applied to treat other complications associated with stroke.

“The glove is an innovative idea that has shown some promise in pilot studies,” Lansberg said. “If proven beneficial for patients with impaired arm function, it is conceivable that variations of this type of therapy could be developed to treat, for example, patients with impaired gait.”

Recovering after a stroke isn’t easy, but Neofect is here to help patients track their rehabilitation progress with an innovative wearable solution.

At CES 2019, the company exhibited its Rapael Smart Glove, a high-tech rehab device that helps stroke patients improve their hand movements. The device also syncs with an app, where patients can play rehabilitation games and track milestones.

Neofect didn’t disclose a price for the Rapael Smart Glove, but customers can go on the company’s website to buy it. The Rapael Smart Glove is also available for clinics that need stroke rehabilitation equipment.

Using the Rapael Smart Glove is very easy: Gently slide on the device, connect to the Rapael App with a smartphone or tablet, and play a variety of rehabilitation games. The app’s fun games include virtual tennis matches and house painting, and they’re available in different levels to balance challenge and motivation. Plus, the Rapael App collects practice data for patients, so they can track their hand recovery progress.

With the Rapael Smart Glove, patients can practice hand exercises and improve dexterity over time. An advantage of the Rapael Smart Glove is that it can help stroke patients who might not have immediate access to hospitals or physical therapy facilities, so they can work on their hand movements without leaving home.

“We aim to help patients all around the world including, but not limited to, those unable to receive appropriate treatment due to economic or geographic reasons,” says Neofect’s website. “By providing rehab training products and services that are available anytime and anywhere, we are committed to improving patient’s rehab experiences and quality of life.”

[WEB SITE] RAPAEL Smart Glove Receives CES 2017 Innovation Award – Rehab Managment

The RAPAEL Smart Glove, a wearable device from NEOFECT, Burlingame, Calif, offers at-home game-based hand therapy for stroke patients who cannot visit a clinic due to economic or geographic reasons.

Simply wear the glove, connect to the “RAPAEL” app, and play the rehabilitation games.

The Smart Glove—a CES 2017 Innovation Awards Honoree for the hospital edition—leads the patient through games that stimulate daily activities, in one or two 30-minute sessions per day.

Built-in sensors capture the patient’s movement and positioning data, and transfer it via Bluetooth to a tablet, where it is analyzed. This analysis enables the games’ difficulty levels to be adjusted and the patient’s exercise schedule to be customized.

Training movements include forearm supination/pronation, wrist flexion/extension, wrist radial/ulnar deviation, and finger flexion/extension, per the company’s website.

[WEB SITE] SignLanguageGlove gives voice to hearing and speech impaired

The SignLanguageGlove features a handful of sensors to convert hand and finger movements into text and spoken dialogue

In an effort to further open the lines of communication for people with hearing and speech disabilities, a university student in London is developing a smart glove that converts sign language into text and spoken dialogue. Dubbed the SignLanguageGlove, the wearable device features a handful of sensors to convert hand and finger movements into words, with its creator now looking to add real-time language translation to the mix.

Designer and student at Goldsmiths, University of London Hadeel Ayoub is currently on the third iteration of her smart glove. Equipped with five flex sensors to monitor the bends and curves of each finger and an accelerometer to detect the orientation of the glove, the first experimental version took signs and turned them into visual letters on a screen.

She soon followed up with an improved model that was faster and more robust, featuring smaller, more discreet hardware and text that scrolled on a screen. The latest model features a text-to-speech chip with the hardware sewn into the lining of the glove.

She is now hard at work integrating a language translation function into the system. An Arabic, French and English speaker herself, Ayoub is looking to add Wi-Fi to the glove so that its motion can be relayed wirelessly to smartphones or tablets, where an app would handle the translation. She also plans to add a motion sensor for better mapping and develop a smaller version for children.

Gloves that turn sign language into audible dialogue is a concept that has been explored before. Back in 2009, the open-source AcceleGlove, which was intended for, among other things, interpreting sign language, was released. Then in 2012, a similar set of gloves took out the Microsoft Imagine Cup. But smartphones and tablets have come some way in that time, allowing for fresh takes on the concept.

Goldsmiths says that several companies have approached Ayoub with a view to mass producing the SignLanguageGlove, which would have an estimated cost of around £255 (US$385). But Ayoub says if it does come available as a commercial product, she hopes that schools and businesses will buy them for students, patients and employees with hearing and speech impairments.

[WEB SITE] This is affordable home rehab for stroke patients


When Ban Ho Young was a university student, his father passed away after suffering a stroke. Shortly thereafter, two of his uncles survived strokes and joined the tens of thousands of South Korean stroke patients undertaking rehabilitation therapy. That process, both costly and time-consuming, was too much for Ban’s family to endure – his uncles dropped out of their rehabilitation programs before regaining full use of their hands.

Ban estimates that nearly 85 percent of South Koreans who start stroke rehabilitation leave their programs before completion. Patients face a difficult trade-off of pros and cons. Inpatient care has is effective in rehabilitating stroke survivors, but it costs KRW 20 million (about US$17,130) per year after insurance. Outpatient care, while much cheaper, yields less reliable improvements and requires travel to and from facilities several times each week.

“Survival rates are rising, which is great news, of course,” Ban says. “But there aren’t enough physical therapists and the system just can’t cope.”

In 2010, Ban decided that something needed to be done to improve rehabilitation results for stroke patients. His startup Neofect has developed and marketed a smart glove called Rapael, which allows for daily home rehabilitation at a price that most patients can afford.

Gamifying rehab


Rapael looks like a next-generation video game controller, because in effect, that’s what it is. Sensors within the glove monitor movement in the forearm, wrist, and fingers to provide inputs for games included in the glove’s software. Patients twist their forearms and bend their wrists and fingers to fish or catch baseballs in a game setup similar to Wii Sports. Ban feels that gamification is the most important aspect of the new device.

“Just moving someone’s hand in a certain way won’t improve that person’s condition because a large part of rehab takes place in the brain,” Ban explains. “We see a lot of focus on the clinical side of things and not enough on the motivational.”

The games provide patients with a much-needed boost of enthusiasm, but their real value is twofold – the startup also collects data from each session to tailor regimens for each patient. The company already employs a handful of data scientists to crunch the numbers. Data on how many baseballs a patient is able to catch in one hour can show a discouraged patient that they are, in fact, improving; it also gives Neofect clues about how to improve its game.

Data analysis is where Neofect hopes to best competitors, some of which offer Kinect-style gaming or console-based exercises. Companies like Limbs Alive offer products that require patients to hold controllers from the start, and because progress is measured locally, there’s no big data to mine for effective rehab programs.
