 note = {筋は伸張位に固定すれば肥大し, 短縮位にすれば萎縮する。しかし, 萎縮予防目的に伸張位固定すれば, 拮抗筋の萎縮が惹起される。そこで本研究では, 臨床的に可能な短時間筋伸張位保持の効果を, 動物実験により組織化学的に検索した。方法は2週間の寡運動(非荷重)中, ラット右足関節を一日20分間, テープで最大背屈位に保持し, ヒラメ筋を伸張した。左側は寡運動のみとした。その結果, 伸張群の筋湿重量および筋線維断面積は, タイプI・II共に寡運動群より有意に大きかった。以上より, 短時間筋伸張位保持は, 廃用性萎縮の進行を抑制できることが示唆された。 The purpose of this study was to investigate the effect of maintaining a stretched position for a short period of time in preventing disuse muscle atrophy. Soleus muscle (SOL) atrophy was induced by hindlimb suspension of male Wistar rats (n=13) for two weeks. The right SOL was maximally stretched with dorsi-flexion of the ankle joint for 20 minutes/day, 5 times/week, with non-elastic tape. The left SOL was unweighted only, without stretching. Muscle ATPase histochemical staining, followed by morphometrical analysis, demonstrated that the muscle-to-body weight ratio and cross-sectional area of type I and II fibers in stretched SOL were significantly larger than in non-stretched SOL. The percentage distribution of muscle fiber types did not change. The results indicate that it is possible to delay the progression of disuse muscle atrophy by maintaining a stretched position for brief periods of time., 金沢大学大学院医学系研究科活動能力回復学},
