"Game and film are driving the development of VR (virtual reality) technology, but medical care will be the largest market for VR." Walter Greenleaf, director of the Stanford VR Medical Research Institute, visited China in mid-July. In a public speech in Shanghai, I said.
Greenleaf is one of the global pioneers in applying virtual reality technology to healthcare. He has been researching VR technology for more than 30 years. In his view, the combination of VR and medical treatment can be achieved in four aspects: medical intervention, clinical diagnosis, medical training, health care.
According to a research report on virtual reality medical services market released by research institute RnR Market Research, the global VR medical service market will grow at a compound growth rate of 19.37% from 2014 to 2019.
Although the application of VR in the medical field began in Europe and the United States, domestic startups and technology companies are actively deploying.
VR is especially suitable for the treatment of mental illness
VR technology is used to treat depression, allowing patients to take turns playing the role of adults and children in a virtual scene.
“The new VR technology is increasingly infiltrating into medical treatment, especially suitable for application in the psychiatric field.†Xu Yifeng, dean of the Shanghai Mental Health Center, told the news () that “the psychiatric department is mostly reflected in the pathological state of the brain. Other problems, such as thinking and emotion, are difficult to reproduce in real scenes. It is easier to use VR to train patients or treat brain emotions."
It is understood that the Shanghai Mental Health Center has reached an agreement with Shanghai eDoctor Wing Information Co., Ltd., the two sides will first cooperate to study the use of VR technology to treat social phobia. The expert team of Shanghai Mental Health Center will provide professional medical advice from the perspectives of project design and intervention scene design, and Wing is responsible for the software and hardware research and development required for VR technology.
Xu Yifeng said that in the past, the main methods of treating social anxiety disorders were psychotherapy and drug therapy. The overall therapeutic goal is to control and alleviate social anxiety-related anxiety syndromes, reduce fear avoidance behavior, improve patients' social function, and improve quality of life.
"In the past, when we were treating, we needed patients to imagine a lot of scenes. This method is very subjective, there is a lot of uncertainty, and the treatment effect varies from person to person." Xu Yifeng said, but now patients only wear VR glasses. You can enter the virtual scene set by the doctor and get immersive.
Huang Yingfeng, the founder of Wing Duo, said that the biggest difficulty in using VR to treat social phobia in the short term is the part of the software, that is, the design of the treatment scene. "The data of the curative effect is digitized by standardized psychotherapy. If it can be proved that the evaluation effect is effective, The output will be faster than expected."
“We have designed a variety of social situations for patients, and the pressure on these scenarios is gradually increasing. In certain scenarios, patients will be required to complete the assigned tasks.†Wing Multi Company Partner, Strategic Market Director Zhang Wei said, “For example, in the introduction of the design, the patient will be in a cafe, he will be asked to see a strange customer to submit a document, this is a simple one-on-one scene. Then slowly Transition to a one-to-many, many-to-many complex scenario. By observing the patient's response, the psychologist in the background can choose to instantly enhance or reduce the treatment level."
"The application of VR in psychiatric treatment may be unlimited." Xu Yifeng said, "After this project is completed, we will try on other mental illnesses." Currently, virtual reality is still used for treatment. The traumatic sequelae of veterans, phantom limb pain in children with disabilities, children with ADHD, autism, cognitive dysfunction, etc., even have effects on improving acrophobia, claustrophobia, and airplane phobia.
