胸椎伸展モビリティ

胸椎後弯・猫背・巻き肩

長時間のスマホやデスクワークで胸椎が過度に丸まり固定されると、首や腰に代償性の過剰な負荷がかかります。

臨床的所見

主な症状

背中中央部の張り感、肩が前に巻き込まれた姿勢、深い呼吸のしにくさ

重要注意点

避けるべき動作

✗ 背中をさらに丸めるような動作

💡 理学療法士のアドバイス

フォームローラーでの胸椎伸展やオープンブック（胸ひらき体操）で胸郭の可動域を広げましょう。

CLINICAL QUESTIONS & ANSWERS

よくある臨床の質問: 胸椎後弯・猫背

Q Can thoracic posture exercises reverse upper back curvature?

Yes. Functional kyphosis caused by postural habit and muscle weakness responds rapidly to thoracic extension over a foam roller and strengthening the lower trapezius with Wall Angels and prone Y-T-Ws.

Q Why does upper back slouching cause shortness of breath?

A rounded thoracic spine compresses the anterior ribcage, restricting diaphragm descent and rib cage excursion, reducing vital lung capacity by up to 30%.
