Virtual reality goes far beyond playing games with titles like Arizona Sunshine, Moss, Robo Recall, and Tetris Effect. VR also is playing an ever-growing role in health care settings. The global market for VR in health care could reach $3.8 billion in 2020, according to one estimate.

VR is touching all corners of heath, including robotic surgeries, training, pain management, and behavior modification, according to InterbrandHealth, a health care branding agency. And these technologies are happening right here in Houston.

Researchers at Houston Methodist Cancer Center are exploring whether exposure to nature, through either a real garden or VR, can ease pain and distress in cancer patients who are undergoing chemotherapy. This approach might decrease the need for prescription painkillers.

Houston Methodist and Texas A&M University are leading this test. Renee Stubbins, a clinical dietitian at Houston Methodist Cancer Center, and Ashley Verzwyvelt, an infusion oncology nurse at the cancer center, proposed the research after several years of studying ways that nature can boost the healing process.

"Anything that affects our patients' comfort — including easing pain and anxiety, and possibly reducing the need for pain medications — is important to their recovery," Stubbins says in a release. "People have an innate connection to nature, and we hope the patients will respond positively."

Three dozen cancer patients receiving chemotherapy infusions every two weeks during at least six cycles will be randomly assigned to one of three rooms: a live-garden-view room; a window-less room, and a room where nature can be experienced through a VR headset.

Teaming up with Houston-based Skyline Art Services, local artist Gonzo247 produced a nature-inspired mural on a wall behind the live garden to create an immersive environment. The mural depicts a flowering garden, blue sky and sunset that enhance the live garden of Texas wildflowers in the foreground.

Researchers will measure pain, distress, blood pressure, heart rate, and saliva cortisol at the beginning and end of each infusion visit. Saliva cortisol, a hormone produced when the body is stressed, helps gauge a patient's condition.

"If this study proves that real or virtual elements of nature help the healing process, then it has potential to positively impact our patients," Verzwyvelt says. "Some of them are hesitant to take pain medication due to concerns of addiction and adverse side effects, so I'm excited to see the possibilities this kind of research could bring."

Houston Methodist Cancer Center says the VR experiment could have implications for treatment of an array of patients who are immobile or whose immune systems are compromised.

"We looked at multiple studies that showed exposure to nature can reduce stress levels and actually increase productivity and creativity," says Ann McNamara, associate professor in the Department of Visualization at Texas A&M. "We want to see if we can reproduce those effects in a natural environment in virtual reality."

The study is being financed by the Center for Health & Nature, a joint initiative of Houston Methodist, Texas A&M and Texan by Nature, a nonprofit conservation group founded by former first lady Laura Bush. The Center for Health & Nature, housed at Houston Methodist Hospital, debuted in 2018.

"There's a gap in research regarding what nature factors lead to increased health, what exposure to nature means, and how much exposure is needed," Bush said when the center was announced.

TMC lands $3M grant to launch cancer device accelerator

cancer funding

A new business accelerator at Houston’s Texas Medical Center has received a nearly $3 million grant from the Cancer Prevention and Research Institute of Texas.

The CPRIT grant, awarded to the Texas Medical Center Foundation, will help launch the Accelerator for Cancer Medical Devices. The accelerator will support emerging innovators in developing prototypes for cancer-related medical devices and advancing them from prototype to clinical trials.

“The translation of new cancer-focused precision medical devices, often the width of a human hair, creates the opportunity to develop novel treatments for cancer patients,” the accelerator posted on the CPRIT website.

Scientist, consultant, and entrepreneur Jason Sakamoto, associate director of the TMC Center for Device Innovation, will oversee the accelerator. TMC officials say the accelerator builds on the success of TMC Innovation’s Accelerator for Cancer Therapeutics.

Each participant in the Accelerator for Cancer Medical Devices program will graduate with a device prototype, a business plan, and a “solid foundation” in preclinical and clinical strategies, TMC says. Participants will benefit from “robust support” provided by the TMC ecosystem, according to the medical center, and “will foster innovation into impactful and life-changing cancer patient solutions in Texas and beyond.”

In all, CPRIT recently awarded $27 million in grants for cancer research. That includes $18 million to attract top cancer researchers to Texas. Houston institutions received $4 million for recruitment:

  • $2 million to the University of Texas MD Anderson Cancer Center to recruit Rodrigo Romero from Memorial Sloan Kettering Cancer Center in New York City
  • $2 million to MD Anderson to recruit Eric Gardner from Weill Cornell Medicine in New York City

A $1 million grant also went to Baylor College of Medicine researcher Dr. Akiva Diamond. He is an assistant professor at the medical college and is affiliated with Baylor’s Dan L. Duncan Comprehensive Cancer Center.

Houston students develop cost-effective glove to treat Parkinson's symptoms

smart glove

Two Rice undergraduate engineering students have developed a non-invasive vibrotactile glove that aims to alleviate the symptoms of Parkinson’s disease through therapeutic vibrations.

Emmie Casey and Tomi Kuye developed the project with support from the Oshman Engineering Design Kitchen (OEDK) and guidance from its director, Maria Oden, and Rice lecturer Heather Bisesti, according to a news release from the university.

The team based the design on research from the Peter Tass Lab at Stanford University, which explored how randomized vibratory stimuli delivered to the fingertips could help rewire misfiring neurons in the brain—a key component of Parkinson’s disease.

Clinical trials from Stanford showed that coordinated reset stimulation from the vibrations helped patients regain motor control and reduced abnormal brain activity. The effects lasted even after users removed the vibrotactile gloves.

Casey and Kuye set out to replicate the breakthrough at a lower cost. Their prototype replaced the expensive motors used in previous designs with motors found in smartphones that create similar tiny vibrations. They then embedded the motors into each fingertip of a wireless glove.

“We wanted to take this breakthrough and make it accessible to people who would never be able to afford an expensive medical device,” Casey said in the release. “We set out to design a glove that delivers the same therapeutic vibrations but at a fraction of the cost.”

Rice’s design also targets the root of the neurological disruption and attempts to retrain the brain. An early prototype was given to a family friend who had an early onset of the disease. According to anecdotal data from Rice, after six months of regularly using the gloves, the user was able to walk unaided.

“We’re not claiming it’s a cure,” Kuye said in the release. “But if it can give people just a little more control, a little more freedom, that’s life-changing.”

Casey and Kuye are working to develop a commercial version of the glove priced at $250. They are taking preorders and hope to release 500 pairs of gloves this fall. They've also published an open-source instruction manual online for others who want to try to build their own glove at home. They have also formed a nonprofit and plan to use a sliding scale price model to help users manage the cost.

“This project exemplifies what we strive for at the OEDK — empowering students to translate cutting-edge research into real-world solutions,” Oden added in the release. “Emmie and Tomi have shown extraordinary initiative and empathy in developing a device that could bring meaningful relief to people living with Parkinson’s, no matter their resources.”
