Abstract

  許多研究報告報導針刺治療可以緩解膝部骨性關節炎病人的疼痛。大部分針刺治療效果的資料來自西方已開發國家,很少來自亞洲國家。此前驅研究目的是探討在例行的西醫治療加上針刺治療對於膝部骨性關節炎成年病人緩解疼痛和改善關節活動的成效。採用前瞻性、非隨機控制的研究設計,膝部骨性關節炎病人分配至接受例行的西醫治療加上8次針刺治療組(n=12),或者只有例行的西醫治療組(n=12),先收完實驗組資料再收集對照組資料。使用走路六分鐘距離、疼痛視覺類比量表、以及膝部骨性關節炎醫療照護成效量表於介入措施前與4週結束後評估治療效果。調整共變項以後,針刺治療組與對照組皆顯示有顯著的時間效益於走路六分鐘距離、疼痛視覺類比量表,以及膝部骨性關節炎醫療照護成效量表的疼痛範疇和關節活動範疇(p<.01)。但是兩組的進步改變量沒有達到顯著差異。本研究結果顯示例行的西醫治療加上針刺治療似乎能夠令膝部骨性關節炎成年病人的疼痛緩解和關節活動改善。
  Acupuncture has been repeatedly reported to relieve pain associated with osteoarthritis of the knee. As the vast majority of information on the effectiveness of acupuncture on this condition is based on data collected in Western countries, little is known about patients with osteoarthritis of the knee in Asian countries. In this pilot clinical study, acupuncture was incorporated into the standard care for adult patients with osteoarthritis of the knee to determine its contribution to pain relief and improved mobility. In a prospective, non-randomized controlled study, patients with osteoarthritis of the knee were separated into two groups. The first (the experimental group; n = 12) was scheduled for up to 8 sessions of acupuncture in addition to standard care, while the second (the control group; n = 12) received standard care only. Measurements using the six-minute walking distance test, pain visual analogue scale, and osteoarthritis of the knee outcome measurement were taken at baseline and after 4 weeks. Both study and control groups showed significant improvement with respect to time effects in terms of six-minute walking distance, pain visual analogue scale, pain domain and mobility domain scores determined by the osteoarthritis of the knee outcome measurement (p < .01), after adjusting for covariables. However, improvements measured in the study group did not differ significantly from those in the control group. Patients with osteoarthritis of the knee seemed to experience clinical improvements in six-minute walking distance, pain relief and mobility when their standard care was supplemented with acupuncture.
