Virtual-reality-Assisted treatment of flight phobia.

Authors: Wallach HS, Bar-Zvi M

BACKGROUND: Flight phobia is a common and debilitating specific phobia. Recently, an effective technology, called Virtual Reality (VR), has been developed for the treatment of various anxiety disorders including flight phobia. METHOD: This article reports the results of a pilot study consisting of four subjects treated for Flight Phobia using Virtual Reality. RESULTS: All four subjects flew post-treatment. They experienced a significant reduction in fear of flying on two measures - anxiety about flying and global rating of fear of flying. Limitations: Due to the small sample size, the lack of a control group, and the lack of objective measures, caution must be exercised in interpreting the results. CONCLUSIONS: The use of Virtual Reality psychotherapy is relatively new worldwide, as well as in Israel. This study suggests the utility of implementing this technology in Israel.

Changing daily wound dressings provokes a substantial amount of pain in patients with severe burn wounds. Pharmacological analgesics alone often are inadequate to solve this problem. This study explored whether immersive virtual reality (VR) can reduce the procedural pain and anxiety during an entire wound care session and compared VR to the effects of standard care and other distraction methods. Nineteen inpatients ages 8 to 65 years (mean, 30 years) with a mean TBSA of 7.1% (range, 0.5-21.5%) were studied using a within-subject design. Within 1 week of admission, standard care (no distraction), VR, or another self-chosen distraction method was administered during the wound dressing change. Each patient received the normal analgesic regimen. Pain was measured with visual analog thermometer scores, and anxiety was measured with the state-version of the Spielberger State Trait Anxiety Inventory. VR distraction and television distraction both significantly reduced pain ratings compared with no distraction. Thirteen of 19 patients reported clinically meaningful (33% or greater) reductions in pain during VR distraction. No side effects were reported. There were no significant reductions in anxiety. No correlations were found between the reduction in pain ratings and patient variables like age, sex, duration of hospital stay, or percentage of (deep) burns. After comparing different distraction methods, only VR and television showed significant pain reductions during wound dressing changes. The effects of VR were superior, but not statistical significant, to that of television. There was no significant reduction of anxiety ratings.

Internal and external imagery perspective measurement and use in imagining open and closed sports skills: an exploratory study.

This study explored the measurement and use of internal and external imagery perspectives during imagery of open and closed sports skills. Participants (N=41; male=23; female=18), ages 14 to 28 (M = 19.4 yr.; SD = 3.1), who were recruited from undergraduate classes in human movement and physical education, and local sporting teams, completed the Imagery Use Questionnaire and then imagined performing eight common sports skills, four open skills and four closed skills, in a random order. Participants provided concurrent verbalisation during their imagery. Immediately after imagining each skill, participants completed a rating scale and retrospective verbalisation of imagery perspective use. Analysis indicated that the questionnaire gave a general imagery perspective preference but was not a strong predictor of imagery used on specific occasions. The three measures of imagery perspective were equivalent in imagining performing particular skills. Participants experienced more internal imagery than external imagery while imagining the eight sports skills, but there was no significant difference between perspective use on the open and closed skills.
