초록
Since spinal cord injury (SCI) leads to persistent disability and a decreased quality of life, a novel intervention method that addresses functional problems is needed. This study applied immersive mixed reality (MR) environment to a patient with SCI and investigated the effects on electroencephalogram (EEG) changes and motion sickness. The participant was a 64-year-old male diagnosed with SCI 20 years ago, with the injury located at the thoracic levels 1-2. He uses a wheelchair and has difficulty using both hands while seated. EEG measurements were obtained using Neurosky, and motion sickness was assessed using a motion sickness questionnaire. The intervention consisted of a game in which the subject wore a head-mounted display and used hand switches to catch virtual monsters in an MR environment for approximately 4 minutes. As a result, attention increased from 31.74% before the MR session to 71.73% during the MR, and RAB decreased from 1.33 before the MR to 0.85 during the MR. This indicates an increase in beta waves. And the participant reported that the immersive MR was enjoyable and realistic, describing the game as relatively comfortable and easy to engage with. Therefore, these findings suggest that immersive MR could serve as a promising new intervention tool for patients with SCI.
