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."

Astrodome group seeks new ideas for future of historic Houston landmark

8th Wonder News

The Astrodome may have once been touted as the Eighth Wonder of the World, but its current condition remains one of Houston's most famous follies. In an effort to find a better use for the iconic building, The Astrodome Conservancy has released a Request for Information (RFI), inviting proposals from interested parties on how the historic landmark might be used in the future. Respondents have until September 8 to submit their responses at the official conservancy site.

“This RFI is an opportunity for the market to help shape a shared vision for the Astrodome,” said Beth Wiedower Jackson, executive director of the Astrodome Conservancy, in a release. “We are looking to gather creative, feasible, and financially viable ideas that reflect both the significance of the Astrodome and its potential as a catalyst for future development.”

When the Astrodome opened in 1965, it was a marvel of engineering and the world's first air-conditioned, multi-purpose domed sports stadium. It remained an iconic part of Houston until changing trends in sports sent the Astros and the Houston Livestock Show and Rodeo to newer stadiums with modern amenities. After the 2003 rodeo, the dome was closed, except for a brief use as an evacuation shelter for Hurricane Katrina.

A decades-long fight over what to do with the Astrodome followed that closure. The City of Houston condemned the building for various code violations in 2009. Fully renovating it would cost over $700 million — a tall order for taxpayers. Demolishing it would be far cheaper (around $55 million), but its status on the National Register of Historic Places makes that virtually impossible. Meanwhile, Harris County pays hundreds of thousands of dollars a year to maintain the building.

Proposals for the space have run the gamut. In 2024, the Astrodome Conservancy proposed Vision: Astrodome, which would transform the building into an indoor mall and event space. That still appears to be the foundation of the plan according to the RFI.

The RFI is seeking private investment to partner with the Harris County property. Proposals are merely for planning purposes and will not automatically lead to contracts for development. Section 2.3 states that participants in the new mixed-use space will "require back-of-house infrastructure improvements to support reliable operations at scale," likely meaning that the plan is to fund some of the much-needed renovations via tenants. However, the RFI points out that participants in the revitalized Astrodome will also be eligible for historic space preservation tax credits.

While Vision: Astrodome seems committed to using the stadium as a public space for the entertainment of Houstonians, the RFI is clear other options are on the table.

The Astrodome possibly being used to house a data center is specifically mentioned, though the RFI mandates such a proposal would need to be very upfront about the infrastructure demands and continuing operating costs of such a project. Public backlash against data centers led to Governor Greg Abbott ordering a pause on grid connections to them pending further review.

"The Astrodome presents a unique opportunity for adaptive reuse and redevelopment that honors its legacy while positioning it for long-term community and economic impact," said the conservancy in the release announcing the RFI.

Houston lands $14M in latest CPRIT grants to advance cancer, lab-on-chip research

cancer funding

Thanks to a $4 million grant from the Cancer Prevention and Research Institute of Texas, the University of Houston has recruited a top-tier researcher developing AI-powered lab-on-a-chip technology for early cancer detection.

Tianhong Cui, a professor of mechanical engineering at the University of Minnesota Twin Cities and an adjunct professor of physiology and biomedical engineering at the Mayo Clinic, specializes in microelectromechanical systems and advanced manufacturing at microscale and nanoscale levels. In addition to lab-on-a-chip systems, Cui focuses on biosensors and water sensors.

Lab-on-a-chip devices deliver big results in a tiny package

The CPRIT grant supports Cui’s development of a microscale lab-on-a-chip system for early cancer detection and post-therapy monitoring.

“Lab-on-a-chip technology crams an entire lab’s worth of functions into a tiny device roughly the size of a USB stick,” according to Built In.

Common uses for the technology include medical diagnostics, point-of-care testing, and environmental monitoring.

Lab-on-a-chip work being carried out at UH and elsewhere in Houston promises to revolutionize cancer detection and treatment. For instance, Houston biotech company iBiochips, a spinout from the Houston Methodist Research Institute, makes lab-on-a-chip devices that bolster cancer detection and therapy.

Four local organizations gain $10 million in CPRIT grants

Four other Houston-area organizations received an additional $10 million in grants in CPRIT’s latest round of funding:

  • University of Texas MD Anderson Cancer Center received two $2 million grants to recruit researchers Zheqi Li of Harvard University’s Dana-Farber Cancer Institute and Nikolaos Koundouros of Weill Cornell Medicine.
  • Rice University received one $2 million grant to recruit researcher Maria Akoppyan, formerly of the University of Southern California.
  • UT Medical Branch at Galveston received one $2 million grant to recruit researcher Cristina Santarossa of Johns Hopkins University.
  • Houston-based biopharma company Pulmotect received one $2 million grant to support better outcomes for cancer patients by activating immunity in the lungs as a first line of defense against germs.

The funding was part of $35 million in new CPRIT grants for institutions and companies across Texas approved at the organization's most recent meeting. To date, CPRIT has awarded more than $4.2 billion in grants.

“These awards support research across the cancer continuum from prevention to new classes of therapeutics,” said Dr. Scott Hiebert, chief scientific officer of CPRIT, said in a news release. “The work of these investigators will impact the lives of Texans across the state.”
