Virtual Reality Experiences on Acute Pain and Distress

The Efficacy of Virtual Reality Experiences on Acute Pain and Distress Caused by Fluoroscopic Pain Intervention in Chronic Pain Patients - A Randomized Controlled Clinical Trial

The aim of this study is to evaluate the efficacy of virtual reality experiences on acute pain and distress caused by fluoroscopic pain intervention in chronic pain patient.

The investigators perform lots of interventions for patients. But unfortunately, patients cannot help being exposed to the acute pain and fear during the interventions. "Virtual Reality(VR)" is a state-of-art advanced technology, which is now being extended to various medical fields such as pain management, dental treatment, body rehabilitation and cancer pain. There is no study that have conjugated the virtual reality experience for patients' acute pain and anxiety which occurs during the pain interventions. So the investigators like to evaluate the effects of virtual reality experience on acute pain and anxiety precipitated by the pain interventions.

Inclusion Criteria:

If all of the following conditions are met :

• Patient who has chronic pain lasting more than 3 months and whose pain doctor determined that he or she needs following fluoroscopic pain intervention : Lumbar sympathetic ganglion block (LSGB), Fluoroscopic-guided pulsed radiofrequency ablation (pRF), Fluoroscopic-guided radiofrequency thermocoagulation (hRF)
• Adults who are at least 20 years of age
• Patients whose American Society of Anesthesiologists(ASA) physical status is classified as 1 or 2.
• A person who voluntarily agrees to participate in this clinical trial and has agreed in informed consent.

Exclusion Criteria:

If the subject falls under any of the following conditions :

• Patients who cannot have virtual reality experience due to hearing or visual impairment
• If the patient has difficulty communicating due to lack of cognitive ability
• Patients that examiners deemed unsuitable for this trial
