 In a half-hour test among 40 hospitalized women in labor, those who
used VR headsets that provided relaxing scenes and messages reported
pain reductions compared with those who didn't get headsets,
researchers said in a presentation at the annual meeting of the
Society for Maternal-Fetal Medicine in Grapevine, Texas.
The next step is to test the technology for longer periods in
laboring women.
"Because that's what the real goal is, right?" said study leader Dr.
Melissa Wong, an obstetrician-gynecologist at Cedars-Sinai Medical
Center in Los Angeles, in a phone interview. "If we're going to say
that people should have them in the hospital, it's not to get them
through 30 minutes of contractions, it's to help them in labor,"
Wong said.
To test the VR headsets, Wong and her colleagues recruited women who
were in the hospital to have their first child and who hadn't yet
taken any pain relief drugs.
All of the participants were having contractions at least every five
minutes and all of them scored their pain level at between 4 and 7
on a 10-point scale, with 10 being the worst pain. Those who used VR
headsets for up to 30 minutes during contractions reported an
average reduction in pain level of 0.52 at the end of that period,
while the control group that didn't get the headsets reported an
average increase in pain of 0.58.
Patients in the control group also had a significantly higher heart
rate after the test period, which was one of the secondary outcomes
Wong's team looked at. There were no statistically meaningful
differences between the groups in blood pressure or delivery
outcomes.
"We believe it has a significant amount of credibility," said Dr.
Michael Foley, chair of the department of obstetrics and gynecology
at the University of Arizona in Phoenix, who wasn't involved in the
study but who has also studied VR as a pain relief method during
labor.

"I think it's another alternative for patients other than having to
take narcotics, epidurals, nitrous oxide or anything in terms of
medication, if they want to go more natural, this is something that
can truly augment that experience," Foley told Reuters Health.
Future research will include upgraded headsets and possibly new
software, as well, Wong said. The study group used a Samsung Gear VR
headset paired with a Samsung smart phone, but the researchers plan
to test patients with a fully integrated unit called Pico VR. It's
more advanced and more comfortable for longer periods of use, Wong
said.
The visualization used in the test is called Labor Bliss, by the
software developer Applied VR. Future research should test different
visualizations and levels of user interaction, Wong noted. "I do
feel pretty passionately that the labor visualization matters," she
said.
An ideal technology, in her view, could integrate an immersive
virtual experience with signals from the woman's body as she
undergoes contractions and labor.
"Anything that's an electric signal could trigger this. I think it
would be super cool to see if we could use the electric signals of
their contractions to change the scenes," Wong said.
