In conventional methods that are used for treating anxiety, there is a risk of exposing the patient to an environment that triggers their anxiety. In the same way,  VR technology develops a certain environment according to the patient’s needs. The basic objective of both the conventional and VR method is to take the patient out of the anxiety.

Differences in Conventional Treatments

How Does Virtual Reality Therapy Work With CBT?

Virtual reality therapy and cognitive-based therapy are two separate entities of treatment. They can be used together to help the clients to get over their phobias.

These techniques include extended exposure to stimuli that causes the client to feel uncomfortable that will allow you to help the patient to substitute negative thoughts with positive and productive ones. For example, a client is afraid to fly in a plane.

So, he is put into the environment where he is forced to fly in a plane. In such a condition the patient confronts his fear and start addressing them. But unlike real life, it is a virtual environment where the therapist is present with the patient that will help and support the patient in the exposure.

As we can see from the above-mentioned example, virtual reality is not only for gamers. It has the biggest use in clinical settings. Combining the advancements of a computer with psychological science and curing the patients accordingly.

Types of Equipment Used in Virtual Reality Therapy

It is still a challenge today due to a lack of clinical evidence and data if and how VR can be used to treat patients both in the clinic and remotely.

Advancement in Technology

As apps are developing every day, there will be a flood of VR apps in an attempt to solve all the mental issues that are widely spread in the world.

Some of the upcoming VR technologies may include remote therapy by a professional practitioner that uses VR as a supplementary tool. Or a virtual therapist using artificial intelligence in the absence of a therapist.

After the 9/11 incident, many US soldiers and army members were willing to use most of the technology bases treatment for mental health and care. While some of them denied the use of VR to cure them suggests that VR will have a barrier in treating them with the disease or any type of disorder.

Advantages

There are several advantages that VR offers for conducting psychiatric research. It gives the user the ability to control the stimuli flow and exposure dose so that controlled clinical research and experiment can be carried out.

For example, a VR approach with substance uses disorder to know the exact timing of craving and decision to use that can be observed in a virtual reality environment. In addition to this, the perfect amount of dose resulting in less craving can be tested using a VR environment rather than in the real world that is more dangerous for the patient.

Disadvantages

Besides having many advantages there are disadvantages to the technology too. In the past years, the cost of virtual reality technology was significantly high which is a disadvantage of VR. VR was very expensive to buy and difficult to set up and sometimes it malfunctions during the use.

The initial cost of VR is still high, but the prices have gone down over time. Developers have started selling smartphone-based VR therapy systems which are surprisingly very low in price.

The technology has been improving and prices are decreasing so that it can get in the hands of every human being easily. But there is still a need for in-depth training for the clinical staff to ensure their ability to cure and trouble-shoot glitches and malfunctioning.
