EaseVRx employs the principles of CBT and other behavioral therapy techniques for the purpose of reduction of pain and pain interference. The prescription device, which is intended for at-home self-use, consists of a VR headset and a controller, along with a “Breathing Amplifier” attached to the headset that directs a patient’s breath toward the headset’s microphone for use in deep breathing exercises. The device’s VR program uses established principles of behavioral therapy intended to address the physiological symptoms of pain and aid in pain relief through a skills-based treatment program. These principles include deep relaxation, attention-shifting, interoceptive awareness–the ability to identify, access, understand and respond appropriately to the patterns of internal signals—and perspective-taking, distraction, immersive enjoyment, self-compassion, healthy movement, acceptance, visualization, knowledge of pain and rehabilitation.
