Lehigh Valley Health Network Regional Burn Center needed a better way to manage burn victims' pain during treatment, since opioids and sedatives can increase hospital stays and costs. One possibility: virtual reality, which controls pain by distraction. But head gear and hand controls hurt patients with burns on their faces, arms, or hands. Lehigh customized a virtual-reality helmet on a mechanical arm so there's only one point of contact with the patient. The $50,000 unit has an infection control mouse and keyboard and is on a mobile cart. The helmet immerses patients in a snowy environment, where they can throw snowballs at animals and other characters.
