抄録

〔目的〕姿勢変化が咀嚼の効率へ与える影響を調べること.〔対象〕健常成人23人とした.〔方法〕4通りの姿勢をランダムにとらせ,試料の咀嚼開始から嚥下までを筋電図で記録し解析した.〔結果〕咀嚼回数はリクライニング30度頭頸部屈曲30度(R30-HN30)がリクライニング90度頭頸部0度(R90-HN0)より多かった.総咀嚼時間はリクライニング30度頭頸部0度(R30-HN0)とR30-HN30がR90-HN0より長かった.バースト持続時間はR30-HN0が他の姿勢より長かった.咀嚼周期はR30-HN0がR90-HN0より長かった.バースト持続時間の変動係数はR30-HN0がR90-HN0より大きかった.〔結語〕咀嚼の効率はR30の姿勢で悪く,R90-HN0の姿勢のときが最も良いことが示唆された.

[Purpose] This study was performed to investigate the influence of changes in posture during feeding on masticatory efficiency. [Subjects] Subjects were 23 healthy young adults. [Methods] The subjects were asked to adopt four postures in a random order. The activity of the masseter muscle was recorded by electromyography from the beginning of chewing to the end. The number of chewing strokes, total chewing time, chewing rhythm and coefficient of variation of chewing rhythm were compared among the postures. [Results] The number of chewing strokes was significantly greater in R30-HN30 than in R90-HN0 . The total chewing time was significantly longer in R30-HN0 and R30-HN30 than in R90-HN0. Burst duration was longest in R30-HN0. Cycle time was significantly longer in R30-HN0 than in R90-HN0. The coefficient of variation of burst duration was significantly greater in R30-HN0 than in R90-HN0. [Conclusion] Masticatory efficiency is the best in R90-HN0.
