フォームローラーによる胸椎伸展モビライゼーション

The thoracic spine naturally curves into kyphosis, but desk posture exaggerates this into a rigid slump. Placing a foam roller or rolled towel across the mid-back creates targeted extension fulcrums (T3-T9) to reverse hunching and uncompress anterior disc margins.

T-SPINE FOAM ROLLER EXTENSION

🎯 T3-T9 Kyphosis Reversal

ステップ別動作手順

臨床プロトコル

1 Sit on the floor with knees bent and place a foam roller horizontally behind your upper back (just below the shoulder blades).
2 Interlace your fingers behind your head to fully support your neck and cervical spine.
3 Keep your buttocks on the floor and gently extend your upper back backward over the roller.
4 Take a slow, deep breath at the end range of extension without arching your lower back.
5 Return to upright and roll the roller 1-2 inches up toward the top of your shoulder blades, repeating the extension.

🎯

フォームの重要ポイント

✓ Keep your neck neutral by supporting your head with your hands like a hammock.
✓ Do not roll onto your lower back; keep the roller strictly between T1 and T10.

⚠️

避けるべき間違い

✗ Never place the foam roller under your lower lumbar spine.
✗ Do not pull on your neck or chin.

🛑

禁忌および中止すべき兆候

Do not perform this movement or modify strictly under clinical supervision if you have:

Severe thoracic osteoporosis (risk of compression fracture)
Acute vertebral fracture

This exercise protocol utilizes proven spinal mechanics: active core co-contraction (McGill stabilization), directional preference extension (McKenzie MDT), and non-compressive axial elongation to facilitate nutrient exchange in the avascular intervertebral disc matrix.
