										<content:encoded><![CDATA[<p style="font-weight: 400;">隨著香港老齡化人口的持續增長，與行動能力相關的疾病的潛在影響將持續擴大。根據最新統計，香港65歲及以上人口約佔總人口15%，其中80歲以上長者膝骨關節炎患病率達20%-24%。這凸顯出嚴重膝關節炎對老年人生活質量的威脅，尤其是晚期膝骨關節炎患者，其行動不便和疼痛日益加劇，嚴重影響日常生活。</p>
<p style="font-weight: 400;"><strong> 什麼是末期膝骨關節炎？</strong></p>
<p style="font-weight: 400;">老年性膝關節骨關節炎（以下簡稱「末期膝骨關節炎」）是骨關節炎的嚴重晚期階段。此階段的主要特徵是膝關節內軟骨嚴重損耗，令人擔憂的是骨骼之間可能直接摩擦，因而在X光片上通常被描述為「骨與骨」。患者經常感到劇烈疼痛、關節僵硬及活動能力下降，日常行走、爬樓梯甚至長時間站立均成挑戰。晨僵時間通常不超過30分鐘，但活動後疼痛會顯著加重。</p>
<p style="font-weight: 400;">此外，膝關節活動範圍縮小，伴隨著摩擦音（劈啪聲）和膝蓋不穩定感，有時患者甚至感覺膝關節「無力」。由於長期廢用和力學改變，關節還可能出現畸形與周圍肌肉無力，進一步加劇症狀。</p>

<p style="font-weight: 400;"><strong>家庭運動與PEMF療法的研究發現</strong></p>
<p style="font-weight: 400;">近期的研究對比了兩組患者：一組接受家庭運動加上主動脈脈衝電磁場療法（PEMF），另一組則接受家庭運動加安慰劑療法。家庭運動包括臀部、膝蓋及小腿肌肉的拉伸和力量訓練，具體包括坐姿等長股四頭肌鍛鍊(SQM)、腳跟滑動鍛鍊(SHL)、彈力帶膝屈曲訓練(SBKF)、彈力帶股四頭肌訓練(SBQ)與半蹲(SS)。研究結果顯示，結合PEMF療法的介入組在肌力增強和疼痛緩解方面表現顯著優於僅接受家庭運動的對照組。PEMF療法透過產生特定頻率和強度的脈衝磁場，在組織內感應出微小電流，促進細胞再生、減少炎症並緩解疼痛。這說明PEMF並非替代家庭運動，而是有助於強化運動效果的輔助手段。</p>
<p style="font-weight: 400;"><strong>具體家庭運動方案指導</strong></p>
<p style="font-weight: 400;">以下是研究報告中介紹的具體動作，協助改善膝關節功能：</p>
<p style="font-weight: 400;">&#8211; SQM（坐姿等長股四頭肌鍛鍊）：坐姿，雙手扶椅，收縮大腿肌肉伸直膝蓋，維持5秒。每週2次。</p>
<p style="font-weight: 400;">&#8211; SHL（坐姿腳跟滑動鍛鍊）：坐姿，雙腳平放地面，緩慢屈膝後伸直，腳趾保持接觸地面。每週1次，每次2組，每組12次。</p>
<p style="font-weight: 400;">&#8211; SBKF（坐姿彈力帶膝屈曲）：彈力帶綁於腳踝，另一端固定，坐姿中膝蓋彎曲，做最大限度的膕繩肌等長收縮。1-4週每週2組，每組12次。</p>
<p style="font-weight: 400;">&#8211; SBQ（坐姿彈力帶股四頭肌訓練）：彈力帶環繞雙腳踝，雙腳與肩同寬站立，一腳抵住彈力帶伸直膝蓋，另一腳作抵抗。4-8週加量至3組，每組12次。</p>
<p style="font-weight: 400;">&#8211; SS（半蹲訓練）：雙手扶椅背，半蹲至膝蓋約45度屈曲，保持5秒。</p>

<h3 style="font-weight: 400;"><strong>傳統診斷方法與療法有效性的思考</strong></h3>
<p style="font-weight: 400;">儘管傳統診斷方法如X光和超聲波檢測膝關節骨關節炎仍具可靠性，Wang et al.與Dekkerhus et al.指出，症狀與影像學表現常存在差異。許多患者症狀可能與其他疾病相似，這凸顯了主動PEMF療法作為輔助治療的價值，尤其是針對因關節退化導致活動力降低的晚期患者。</p>
<p style="font-weight: 400;"><strong>重視早期介入，綜合療法提高生活質量</strong></p>
<p><span style="font-weight: 400;">膝骨關節炎患者可透過居家運動與</span><span style="font-weight: 400;">PEMF</span><span style="font-weight: 400;">療法兩者結合，有效控制症狀與提升膝關節功能。家庭運動通過強化肌肉和穩定關節降低疼痛，</span><span style="font-weight: 400;">PEMF</span><span style="font-weight: 400;">療法則通過細胞層面促進恢復並減輕不適。正如</span><span style="font-weight: 400;">Felson et al.</span><span style="font-weight: 400;">強調，即使是無症狀的骨關節炎患者，病情進展速度驚人，早期介入防止惡化至關重要。鼓勵大家積極參與適合自己的運動計劃，及早採用多元療法，既可延緩疾病進程，又能大幅提升生活品質。</span></p>
