A child-like robot has the potential to comfort young patients during medical procedures and even make their pain more tolerable, according to a research study by Alberta Health Services (AHS) and the University of Calgary. The results published recently emerged in the June issue of the Journal Vaccine, released by New York Times on July 9.

This 2011 winter, 57 children between the ages of four and nine were able to interact with the robot while receiving their seasonal influenza vaccination at Alberta Children’s Hospital. These children reported they experienced little to no pain when compared to youngsters who looked at images on the clinic’s wall during their vaccination.

“These results really do show the potential and benefits for using robotics to help manage a child’s pain while having a medical procedure done,” says lead investigator Tanya Beran, PhD, of the University of Calgary Faculty of Medicine. “For instance, robotics can be used to help manage children’s pain during blood tests and IV starts and other painful procedures, such as stitches or a fracture set. The opportunities are endless.”

The robot, named MEDi™ (which stands for Medicine and Engineering Designing Intelligence), was purchased by the University of Calgary’s Shulich School of Engineering from Aldebaran Robotics — a French startup company headquartered in Paris — and can mimic many things a child can do. It can be programmed to walk, dance, talk with children, play games with them, make eye contact and even give them a high-five.

“From our earlier research, we found that children are curious, imaginative and receptive to interacting with a robot,” says Beran. “They may see it as an extension of themselves or they may see the robot as a companion and even a friend.”

Dr. Susan Kuhn, section chief, Infectious Diseases, Alberta Children’s Hospital, says the MEDi™ robot could be a valuable tool for health providers who offer children vaccinations. Studies show half of all young children experience severe distress and anxiety when it comes to getting vaccinations. “Getting poked with a needle is uncomfortable and is often associated with pain, so children usually arrive crying and literally kicking and screaming,” says Dr. Kuhn.

“Any distress a child experiences early on carries over into adulthood. We want to create a more positive vaccination experience for children now so they can have a better experience later on in life.”

“We found parents were also more relaxed when their children were interacting with a robot during vaccination”., This proved to be the case for Jennifer Crawford when her five-year-old son, Jacob, participated in the study. “Anything that causes my child stress causes me stress but we were put right at ease after meeting the robot”, says Crawford. She says annual influenza immunizations had always been traumatic for Jacob. “We usually have to use desensitizing lotion on the area of his arm where the needle goes, and then he would still be stressed before getting the vaccine, and have negative comments after the vaccine,” she says.

This year, however, Crawford says the vaccine wasn’t a big deal for her son. “You wouldn’t even know he got vaccinated because all he would talk about for the rest of the day was the robot” she says. “The vaccination itself was almost like an afterthought in his story about the robot.” MEDi™ can also be programmed to deliver health information to children at a vocabulary level they understand, says Beran.

Millions of children in North America receive an annual flu vaccination, many of whom are at risk of experiencing severe distress. Millions of children also use technologically advanced devices such as computers and cell phones. Based on this familiarity, we introduced another sophisticated device – a humanoid robot – to interact with children during their vaccination. We hypothesized that these children would experience less pain and distress than children who did not have this interaction.

Method
This was a randomized controlled study in which 57 children (30 male; age, mean ± SD: 6.87 ± 1.34 years) were randomly assigned to a vaccination session with a nurse who used standard administration procedures, or with a robot who was programmed to use cognitive-behavioral strategies with them while a nurse administered the vaccination. Measures of pain and distress were completed by children, parents, nurses, and researchers.

Results
Multivariate analyses of variance indicated that interaction with a robot during flu vaccination resulted in significantly less pain and distress in children according to parent, child, nurse, and researcher ratings with effect sizes in the moderate to high range (Cohen’s d = 0.49–0.90).

Conclusion
This is the first study to examine the effectiveness of child–robot interaction for reducing children’s pain and distress during a medical procedure. All measures of reduction were significant. These findings suggest that further research on robotics at the bedside is warranted to determine how they can effectively help children manage painful medical procedures.
