駝背,不只影響一般人的動作表現,同時也是影響中風和帕金森氏症(Parkinson’s Disease, PD)者動作問題的主因之一。單單來說,如果能改善駝背,對肩膀痛、上肢動作不良及預防跌倒也會有幫助!
為什麼駝背
身體的姿勢靠關節活動、肌肉收縮、神經回饋、腦部整合等共同維持與調整,一但其中一個環節出了問題,姿勢調整自然也會跟著被影響。
中風和帕金森氏症看似不相關,卻都有個共通點:肌肉張力調整異常。
中風 中風後因為軀幹肌肉無力、身體兩側張力獲力量不對稱或左右邊感覺異常,進而讓人容易出現駝背的姿勢。隨著駝背的習慣養成,胸椎的活動就減少,導致日後想挺胸也困難。
帕金森氏症 這是一種因為腦部變化造成動作功能異常的疾病。由於腦部變化,會造成肌肉長時間收縮無法放鬆,因此出現肌肉僵硬(Rigidity) ,進而導致動作及駝背、側彎的情況。
駝背會怎樣?
駝背就是胸椎太彎曲,除了不好看以外,也會造成肩頸關節活動變差和肌肉、關節疼痛問題。
關節活動 不論是手抬不高或是抬高會痛,都是因為肩胛骨沒辦法在抬手過程跟著轉動,導致肩膀附近肌肉要更用力或軟組織被擠壓,進而出現類似『五十肩』的症狀。
疼痛 最大的原因,是在駝背的姿勢之下,頸椎和肩膀附近的肌肉需要用更大的力量才能讓我們抬頭或抬手, 長時間 下來自然會造成肌肉、關節痠痛!
要怎麼自救?
雖然駝背發生在胸椎,但是抬高肩膀的同時,胸椎也會跟著挺直。所以伸懶腰這個動作,就是改善駝背很理想的動作之一。
但是有中風或帕金森氏症的人,常常伴隨有平衡不佳或肩膀、軀幹肌肉無力的問題,所以躺著抬手就是個不錯的選擇!
註:若肩膀有疼痛或其他活動問題者,建議與專業醫療人員討論後再做會比較安全!
