頚椎アライメント

頚胸移行部（C7-T1）症候群・首の付け根の痛み

頭部が前に突き出た姿勢（ストレートネック）は、頚椎から胸椎への移行部であるC7-T1に極度のメカニカルストレスを集中させます。

臨床的所見

主な症状

夕方に悪化する首の付け根（出っ張り骨の周辺）のズキズキとした熱感・疲労感

重要注意点

避けるべき動作

✗ 首を無理に大きく回す過度な回旋運動

💡 理学療法士のアドバイス

チンタック（あご引き体操）を1日数回行い、頭部の重心位置を頚椎の真上へ戻しましょう。

CLINICAL QUESTIONS & ANSWERS

よくある臨床の質問: 首・背中付け根 (C7-T1)

Q What is the "dowager’s hump" at the base of the neck?

It is a postural fat pad and soft-tissue thickening that forms at the C7-T1 junction to protect the spine against chronic shear forces from forward head posture.

Q Do chin tucks really reduce neck and upper back pain?

Yes. Cervical retraction (chin tucks) activates deep cervical flexors (longus colli and capitis) and decompresses the suboccipital and C7-T1 nerve roots.
