第 49 題
關於radial tunnel syndrome的臨床表徵及評估檢測，下列敘述何者正確？
- A 觸診屈曲肌群時有疼痛現象
- B 導致患者的手背側之橈側端（dorsal radial side）的感覺喪失
- C 主要影響到三頭肌（triceps）及肱橈肌（brachioradialis）的肌力表現
- D 在患者中指伸展時給予阻力，有疼痛現象
思路引導 VIP
請回想一下橈神經在穿過前臂側邊時，它是被哪些肌肉層所包夾的？如果我們想透過物理檢查來確認這條神經是否在肌肉管道中受壓，我們應該要求患者進行什麼樣的肌肉收縮動作，才能最有效地增加該管道的內部壓力並誘發不適感？

And, naturally, when one performs resisted middle finger extension, the EDC contracts, ratcheting up the pressure in that delicate tunnel. Voilà, pain. It's almost as if this specific test exists to distinguish it from the rather common “tennis elbow.”
