40名患者被随机分配到试验组和对照组，参加了一项双盲研究，以评估针灸在减轻与骨关节炎相关的慢性疼痛方面的有效性。试验组采用标准穴位治疗，对照组采用安慰剂穴位治疗。治疗前和治疗后的分析显示，两组患者的压痛和疼痛主观报告均有显著改善(P<；0.05)，由两名独立观察者和一名观察者评估。两组对治疗的反应比较显示没有显著差异(>；0.05)。因此，试验组和对照组在治疗后都表现出疼痛的减轻。这些结果可能反映了疾病的自然病程以及各种态度和社会因素。(英国医学杂志293：375-378,1975)
Forty patients, randomly assigned to an experimental and a control group, participated in a double-blind study to assess the effectiveness of acupuncture in reducing chronic pain associated with osteoarthritis. The experimental group received treatment at standard acupuncture points, and the control group at placebo points. Analysis before and after treatment showed a significant (P < 0.05) improvement in tenderness and subjective report of pain in both groups as evaluated by two independent observers and in activity by one observer. Comparison of responses to treatment between the two groups showed no significant( > 0.05) difference.Thus, both experimental and control groups showed a reduction in pain after the treatments. These results may reflect the natural course of illness, and various attitudinal and social factors. (N Engl J Med 293:375–378, 1975)
