A University of Houston professor has taking a huge step in advancing his game-changing stroke recovery tech.

Jose Luis Contreras-Vidal, the director of the UH BRAIN Center, recently published his work on a noninvasive brain-machine in a summer issue of the journal Sensors. InnovationMap first reported on Contreras-Vidal's technology in 2022, when it was being tested.

Contreras-Vidal's device uses a wireless, mobile dry-electrode headset placed on the scalp to convert electroencephalography (EEG) recordings (or measurements of electrical activity in different parts of the brain) to interface with a closed-loop brain–computer (BCI) and communicate with exoskeleton devices. Together, the technology triggers robotic movement based on the wearer's brain activity.

The technology has potential to boost cortical plasticity after a stroke, which can improve motor skills recovery.

According to a statement from UH, a patent is pending on Contreras-Vidal's BCI algorithm and the self-positioning dry electrode bracket used on the scalp. The technology has also now been validated and tested at the University of Houston.

Contreras-Vidal says the technology makes stroke recovery easier for the user and even possible at home.

“Most commercial EEG-based BCI systems are tethered to immobile processing hardware or require complex programming or set-up, making them difficult to deploy outside of the clinic or laboratory without technical assistance or extensive training," he says in a statement. "A portable and wireless BCI system is highly preferred so it can be used outside lab in clinical and non-clinical mobile applications at home, work, or play.”

Additionally, the technology uses off-the-shelf components and is adjustable to fit about 90 percent of the population, according to UH.

"Current commercial EEG amplifiers and BCI headsets are prohibitively expensive, lack interoperability, or fail to provide a high signal quality or closed-loop operation, which are vital for BCI applications,” Contreras-Vidal adds.

The development of this technology was originally funded in part by an $813,999 grant from the National Science Foundation’s Division of Translational Impacts. UH reports that about 795,000 people in the United States suffer from a stroke annually.

Other leaders in Houston’s medical industry have tapped into innovative ways to treat and rehabilitate stroke patients in recent years. Baylor St. Luke's Hospital began using AI to reduce the time it takes to treat patients who've suffered from a stroke in 2021.

Robotic device created at the University of Houston helps stroke patients to rehabilitate

next-gen recovery

Almost 800,000 people in the United States suffer from a stroke annually — and the affliction affects each patient differently. One University of Houston researcher has created a device that greatly improves the lives of patients whose stroke affected motor skills.

UH engineering professor Jose Luis Contreras-Vidal developed a next-generation robotic arm that can be controlled by the user's brainwaves. The portable device uses a brain-computer interface (BCI) developed by Contreras-Vidal. Stroke patient Oswald Reedus, 66, is the first person to use a device of this kind.

Reedus lost the use of his left arm following a stroke that also caused aphasia, or difficulty speaking. While he's been able to recover his ability to speak clearly, the new exoskeleton will help rehabilitate his arm.

When strapped into the noninvasive device, the user's brain activity is translated into motor commands to power upper-limb robotics. As patients like Reedus use the device, more data is collected to improve the experience.

“If I can pass along anything to help a stroke person’s life, I will do it. For me it’s my purpose in life now,” says Reedus in a news release from UH. His mother and younger brother both died of strokes, and Reedus is set on helping the device that can help other stroke patients recover.

Contreras-Vidal, a Hugh Roy and Lillie Cranz Cullen distinguished professor, has led his device from ideation to in-home use, like with Reedus, as well as clinical trials at TIRR Memorial Hermann. The project is funded in part from an $813,999 grant from the National Science Foundation’s newly created Division of Translational Impacts.

"Our project addresses a pressing need for accessible, safe, and effective stroke rehabilitation devices for in-clinic and at-home use for sustainable long-term therapy, a global market size expected to currently be $31 billion," Contreras-Vidal says in the release. "Unfortunately, current devices fail to engage the patients, are hard to match to their needs and capabilities, are costly to use and maintain, or are limited to clinical settings."

Dr. Gerard E. Francisco, chief medical officer and director of the Neuro Recovery Research Center at TIRR Memorial Hermann, is leading the clinical trials for the device. He's also chair and professor in the Department of Physical Medicine and Rehabilitation at McGovern Medical School at UTHealth Houston. He explains that TIRR's partnership with engineering schools such as the Cullen College of Engineering at UH and others around the nation is strategic.

“This is truly exciting because what we know now is there are so many ways we can induce neuroplasticity or how we can boost recovery,” says Francisco in the release. “That collaboration is going to give birth to many of these groundbreaking technologies and innovations we can offer our patients.”

Here are 3 breakthrough innovations coming out of research at Houston institutions

Research Roundup

Research, perhaps now more than ever, is crucial to expanding and growing innovation in Houston — and it's happening across the city right under our noses.

In InnovationMap's latest roundup of research projects, we look into studies on robotics advancing stroke patient rehabilitation, the future of opioid-free surgery, and a breakthrough in recycling plastics.

The University of Houston's research on enhancing stroke rehabilitation

A researcher at the University of Houston has seen positive results on using his robotics on stroke survivors for rehabilitation. Jose Luis Contreras-Vidal, director of UH's Non-Invasive Brain Machine Interface Systems Laboratory, recently published the results of the clinical trial in the journal NeuroImage: Clinical.

The testing proved that most patients retained the benefits for at least two months after the therapy sessions ended, according to a press release from UH, and suggested even more potential in the long term. The study equipped stroke survivors who have limited movement in one arm with a computer program that captures brain activity to determine the subject's intentions and then works with a robotic device affixed to the affected arm, to move in response to those intentions.

"This is a novel way to measure what is going on in the brain in response to therapeutic intervention," says Dr. Gerard Francisco, professor and chair of physical medicine and rehabilitation at McGovern Medical School at The University of Texas Health Science Center at Houston and co-principal investigator, in the release.

"This study suggested that certain types of intervention, in this case using the upper robot, can trigger certain parts of brain to develop the intention to move," he continues. "In the future, this means we can augment existing therapy programs by paying more attention to the importance of engaging certain parts of the brain that can magnify the response to therapy."

The trial was funded by the National Institute of Neurological Disorders and Stroke and Mission Connect, part of the TIRR Foundation. Contreras-Vidal is working on a longer term project with a National Science Foundation grant in order to design a low-cost system that would allow people to continue the treatments at home.

"If we are able to send them home with a device, they can use it for life," he says in the release.

Baylor College of Medicine's work toward opioid-free surgery

In light of a national opioid crisis and more and more data demonstrating the negative effects of the drugs, a Baylor College of Medicine orthopedic surgeon has been working to offer opioid-free surgery recovery to his patients.

"Thanks to a number of refinements, we are now able to perform hip and knee replacements, ranging from straightforward to very complex cases, without patients requiring a single opioid pill," says Dr. Mohamad Halawi, associate professor and chief quality officer in the Joseph Barnhart Department of Orthopedic Surgery, in a press release.

"Pain is one of patients' greatest fears when undergoing surgery, understandably so," Halawi continues. "Today, most patients wake up from surgery very comfortable. Gone are the days of trying to catch up with severe pain. It was a vicious cycle with patients paying the price in terms of longer hospitalization, slower recovery and myriad adverse events."

Halawi explains that his work focuses on preventative measures ahead of pain occurring as well as cutting out opioids before surgery.

"Opioid-free surgery is the way of the future, and it has become a standard of care in my practice," he says. "The ability to provide safer and faster recovery to all patients regardless of their surgical complexity is gratifying. I want to make sure that pain is one less thing for patients to worry about during their recovery."

Rice University's breakthrough on recycling plastics

Houston scientists has found a new use for an otherwise useless byproduct that comes from recycling plastics. Rice University chemist James Tour has discovered that turbostratic graphene flakes can be produced from pyrolyzed plastic ash, and those flakes can then be added to other substances like films of polyvinyl alcohol that better resist water in packaging and cement paste and concrete, as well as strengthen the material.

"This work enhances the circular economy for plastics," Tour says in a press release. "So much plastic waste is subject to pyrolysis in an effort to convert it back to monomers and oils. The monomers are used in repolymerization to make new plastics, and the oils are used in a variety of other applications. But there is always a remaining 10% to 20% ash that's valueless and is generally sent to landfills.

Tour's research has appeared in the journal Carbon. The co-authors of the study include Rice graduate students Jacob Beckham, Weiyin Chen and Prabhas Hundi and postdoctoral researcher Duy Xuan Luong, and Shivaranjan Raghuraman and Rouzbeh Shahsavari of C-Crete Technologies. The National Science Foundation, the Air Force Office of Scientific Research and the Department of Energy supported the research.

"Recyclers do not turn large profits due to cheap oil prices, so only about 15% of all plastic gets recycled," said Rice graduate student Kevin Wyss, lead author of the study. "I wanted to combat both of these problems."

Bairitone Health

Bairitone Health is bringing anatomy imaging for sleep apnea to the home environment. The company's platform maps users' anatomy during natural sleep using a facial patch to determine the root cause of airway obstruction. It then offers effective therapies for each patient. The system is currently in the research and development phase and is being used in clinical trials and studies.

The company was founded in 2022 in the Texas Medical Center's Biodesign program by CEO Meagan Pitcher, CTO Onur Kilic and chief medical officer Britt Cross. It was a member of Activate Houston's inaugural cohort and has participated in numerous accelerators and incubators. It raised a pre-seed round last year of $435,000.

Corveus Medical

Corveus Medical has developed a novel catheter device that allows cardiologists to perform a splanchnic nerve ablation, restoring the pressure balance in patients with moderate heart failure. Its pre-FDA-approved, minimally invasive solution deactivates a nerve that has been demonstrated to be a root cause behind heart failure progression, which allows physicians to treat patients who have traditionally had few options.

The company, formerly known as Caridian Medical, was founded in 2021 by CEO Tyler Melton and CMO Ishan Kamat. It has participated in incubators such as TMC Biodesign, Y Combinator, MedTech Innovator and Fogarty Innovation and was named one of the 10 most promising life science companies at Texas Life Science Forum in 2022. The company says it will move toward validation and verification testing for its device in Q4 of this year.

FibroBiologics

Regenerative medicine company FibroBioligics uses fibroblasts, the body’s most common type of cell, rather than stem cells, to help grow new cells to repair tissue and modulate the immune system. The cell therapies offer treatments for chronic conditions such as degenerative disc disease, multiple sclerosis and non-healing wounds.

The publicly traded company was founded in 2021 by CEO Pete O'Heeron. It opened a new 10,000-square-foot Houston lab earlier this year to scale up research efforts and pave the way for in-house manufacturing. The company says it plans to launch its first clinical trial for diabetic foot ulcers soon, representing the transition of its fibroblast technology to the clinic setting.

Koda Health

Koda Health has developed an advance care planning platform (ACP) that allows users to document and share their care preferences, goals and advance directives for health systems. The web-based platform guides patients through values-based decisions with interactive tools and generates state-specific, legally compliant documents that integrate seamlessly with electronic health record systems. The company also added kidney action planning to its suite of services for patients with serious illnesses last year.

Koda Health was founded out of the TMC's Biodesign Fellowship in 2020 by CEO Tatiana Fofanova, chief medical officer Dr. Desh Mohan, and chief technology officer Katelin Cherry. The company raised a $7 million series A earlier this year, and also announced major partnerships and integrations with Epic, Guidehealth, Medical Home Network, Privia Health and others.

NanoEar

NanoEar has miniaturized hearing aid technology so that it can be implanted across the eardrum, allowing adults with age-related hearing loss to enjoy better sound quality than they would with behind-the-ear hearing aids.

Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist, developed the technology, and the company was founded in 2016 with CFO Willem Vermaat and COO Michael Moore. The company participated in the TMC Innovation Institute in 2016. It has issued nine U.S. patents and performed successful human cadaver and animal proof-of-concept experiments. Its next step is developing a prototype.

Wellysis USA

Wellysis USA Inc. works to detect heart rhythm disorders with its continuous ECG/EKG monitor with AI reporting. Its S-Patch cardiac monitor is designed for extended testing periods of up to 14 days on a single battery charge. The device weighs only 9 grams, is waterproof and designed to be comfortable to wear, and is considered to have a high detection rate for arrhythmias. It is ideally suited for patient-centric clinical trials to help physicians make diagnoses faster, cheaper and more conveniently.

It was established in Houston in 2023 and participated in the JLABS SFF Program the same year. It closed a $12 million series B last year. It was founded by CEO Young Juhn, CTO Rick Kim, CFO JungSoo Kim and chief strategy officer JoongWoo Kim.
