肩夾擊症係指當你舉高手隻手時，肩峰同上臂骨之間空間變窄，令旋轉肌腱同滑囊被夾住，引起疼痛同發炎。

常見原因
– 長期重複頭頂上方動作（例如打球、游水、搬貨）
– 圓肩寒背、頸前傾等不良姿勢
– 旋轉肌群無力或肌力失衡
– 肩關節退化、骨刺或舊傷

症狀
– 舉手、穿衣、梳頭或伸手入背時肩膊刺痛
– 夜晚瞓覺側瞓患側肩膊會痛醒
– 肩膊活動範圍下降，好似「卡住」
– 有時伴隨無力、沉重感

物理治療重點

急性期：舒緩痛楚、減少夾擊
• 冰敷、儀器（干擾波、超聲波）減少發炎。
• 溫和關節鬆動，改善肩峰下空間，配合輕微伸展。

慢性期／恢復期：重整肌力、改善姿勢
• 強化旋轉肌群、肩胛穩定肌及背肌，提升控制。
• 矯正頸胸姿勢，教授合適工作及運動動作，預防再次夾擊。

Shoulder impingement occurs when the space between the top of the arm bone and the acromion becomes narrowed, pinching the rotator cuff tendons and bursa during overhead movement.

Common causes
– Repetitive overhead activities (throwing, swimming, lifting, stocking shelves)
– Poor posture with rounded shoulders and forward head
– Weakness or imbalance of the rotator cuff and scapular muscles
– Degenerative changes, bony spurs, or previous shoulder injuries

Symptoms
– Sharp pain when lifting the arm, dressing, combing hair, or reaching behind the back
– Night pain, especially lying on the affected shoulder
– Feeling of catching or “block” in the shoulder with movement
– Possible weakness or heaviness in the arm

Physiotherapy focus

Acute phase – settle pain and reduce impingement
• Ice and modalities (e.g., electrotherapy, ultrasound) to reduce inflammation.
• Gentle joint mobilisations and stretches to open the subacromial space and ease movement.

Recovery phase – rebuild strength and posture
• Targeted strengthening of rotator cuff, scapular stabilisers, and upper back muscles.
• Postural correction and movement-pattern training for work and sport to prevent recurrence.
