Every morning and night for one month, Dean Peterson donned virtual reality goggles to help him fall asleep. Once a heavy sleeper, he hadn’t slept well since...
The technology, called Mr. MAPP, helps people with limb loss retrain their brains by visualizing the missing body parts.
When he looked at the VR screen, Peterson saw himself with both legs that he used to play games like popping virtual bubbles with his feet or tapping colorful, moving circles. Balakrishnan Prabhakaran and his team at UT Dallas are still tinkering with the device, but the computer science professor said Mr. MAPP has the potential to give amputees an even more realistic therapy option that could lessen the need for medical painkillers.
Peterson and the other study participants gave extensive feedback to the UT Dallas team about what worked and what didn’t. He found that playing the game wearing shorts and with his shoe off was more effective because he saw “flesh and blood,” which made the games feel more real. Despite the excitement surrounding the success of the technology, Peterson said he’s been wary about telling other amputees in the tight-knit limb loss community about his participation in the trial out of fear of getting their hopes up.
