等尺性収縮が持つ特性よりROM訓練への応用が示唆され, 肩関節屈曲100度以下の拘縮肩に対し臨床応用した。16名にストレッチングを主体とした治療, 17名に等尺性収縮を主体とした治療を行い, 1%以下の危険率にて後者の有効性を示した。筋肉におけるレベルで考えるとき, 筋腱移行部 (MTJ) の伸展性欠如が一つの原因であり, その治療を行うには等尺性収縮が非常に有効であることが示唆された. また, 筋収縮がもたらす熱発生は, コラーゲンを中心とした結合組織の粘性低下をもたらし, より有効なROM訓練が行い得ると考えられる。
The porpose of this study was to analyze the effectiveness of the treatment using isometric contraction on frozen shoulder compared with that of the treatment using stretching movement. Thirty three patients with frozen shoulder were divided into two groups: 16 patients were treated with stretching and 17 patients with isometric contraction. They underwent treatment five, ten, twenty times, and their ROM was evaluated after the treatment. A significant difference (p<0.01) in ROM was observed between the two groups. There are two reasons for this result. One reason is that the isometric contraction may stretch the connective tissue of the musculotendinous junction (MTJ). The other reason is based on the alternation of the viscoelastic properties of the intramuscular connective tissue as a result of an increase in actual muscle temperature caused by contraction. It was concluded that the isometric training might be more efficient and effective than the stretching training for the treatment of frozen shoulder.
