Abstract

Objectives: This study aimed to develop a virtual reality (VR)-based oral strength training program and apply it to older adults to assess improvements in oral function. Methods: The oral strength training was conducted 12 times over 6 weeks, from late August to early October 2023, at the participants' institution. Each session lasted approximately 60 minutes. Forty-one participants aged 65 and older were randomly assigned to either the intervention or control group. Results: Following the VR-based oral muscle strength training, the O'Leary index decreased by 0.42 (p<0.01), and the Löe & Silness index decreased by 1.11 (p<0.01). Additionally, there was a 1.24 reduction in tongue tie (p<0.01) and a 0.55 increase in salivation (p<0.05). Post hoc comparisons revealed significant differences between the two groups in gingival bacterial film (p<0.001), gingivitis (p<0.001), and tongue plaque (p<0.01). Conclusions: The study found that VR-based oral muscle strength training can improve oral health among older adults. Therefore, the VR-based oral muscle strength training program developed in this study could be beneficial in health promotion programs for the elderly.

연구목적: 본 연구는 가상현실(VR) 기반 구강 근력 강화훈련 콘텐츠를 개발하고 노인에게 적용한 후 구강 기능의 개선 효과를 확인하고자 하였다. 연구방법: 구강근력 강화훈련은 2023년 8월 말부터 10월 초까지 6주 동안 총 12회를 적용하였다. 수행 장소는 참여 대상자의 소속기관이며, 1회당 소요시간은 약 60분으로 하였다. 연구결과: 가상현실 기반 구강근력 강화훈련 실시 후 치면세균막 지수(O'Leary index)는 0.42점 감소하였으며(p<0.01), 치은염 지수(Löe & Silness index)는 1.11점 감소하였다(p<0.01). 설태는 1.24점 감소하였고(p<0.01), 타액분비량은 0.55g 증가하였다(p<0.05). 사후 두 그룹 간의 비교에서도 치면세균막(p<0.001), 치은염(p<0.001), 설태(p<0.01)에서 유의한 차이를 보였다. 결론: 본 연구 결과, 가상현실 기반 구강근력 강화훈련은 노인층의 구강건강을 일부 향상하는 효과를 나타냈다. 이에 본 연구에서 개발한 가상현실 기반 구강근력 강화훈련 콘텐츠가 노인층을 대상으로 한 건강증진 프로그램에 유용하게 활용될 수 있을 거라 생각된다.
