椅子に座って行う脊椎回旋ストレッチ
Sitting for hours locks the thoracic spine and shortens the quadratus lumborum (QL). This seated twist restores rotational mobility in the mid-back so the lower back does not bear excessive rotational strain.

ステップ別動作手順
臨床プロトコル- 1 Sit tall on the edge of a sturdy chair with both feet flat on the floor, knees at 90 degrees.
- 2 Inhale to lengthen your spine toward the ceiling.
- 3 Exhale and gently twist your torso to the right, placing your left hand on the outside of your right knee.

- ✓ Initiate rotation from your upper/mid back rather than wrenching your lower back.
- ✓ Keep both sit-bones firmly rooted on the chair surface.
⚠️
避けるべき間違い
