[Purpose] To examine whether resistance training for elderly community-dwellers performed with an interocclusal splint resulted in greater lower extremity muscle strength and better balance than resistance training performed without an interocclusal splint. [Subjects and Methods] Eighty-eight elderly persons using Japanese community day centers were randomly divided into two groups: an intervention group (n=45), which performed resistance training with an interocclusal splint; and a control group (n=43), which performed resistance training without an interocclusal splint. The resistance training program comprised a 40-min session performed twice a week for 12 weeks. Outcome measures were the chair stand test (CST), timed up and go test (TUG), and one-leg standing test (OLST). Assessments were conducted before the intervention and every 2 weeks after the start of the intervention. [Results] There was a significant group × time interaction for the OLST, with the intervention group showing significant improvement from 8 to 12 weeks compared to the control group. For the CST and TUG, no significant differences were found between the two groups throughout the 12 weeks. [Conclusion] Resistance training with an interocclusal splint improved the balance ability of elderly community-dwellers more effectively than resistance training without an interocclusal splint.
[目的] 研究老年社区居民使用牙合间夹板进行抗阻训练是否比不使用牙合间夹板进行抗阻训练能带来更大的下肢肌肉力量和更好的平衡能力。[对象与方法] 88名使用日本社区日间照料中心的老年人被随机分为两组：干预组（n = 45），使用牙合间夹板进行抗阻训练；对照组（n = 43），不使用牙合间夹板进行抗阻训练。抗阻训练计划包括每周两次、每次40分钟、为期12周的训练课程。观察指标为椅子站立测试（CST）、计时起立行走测试（TUG）和单腿站立测试（OLST）。在干预前以及干预开始后每2周进行评估。[结果] 在OLST方面存在显著的组×时间交互作用，与对照组相比，干预组在第8至12周有显著改善。对于CST和TUG，在整个12周内两组之间未发现显著差异。[结论] 与不使用牙合间夹板的抗阻训练相比，使用牙合间夹板的抗阻训练能更有效地提高老年社区居民的平衡能力。
