Extracorporeal shock wave therapy has been claimed to be an effective non-invasive treatment for chronic calcific tendonitis of the supraspinatus tendon. However many trials have been criticised for not achieving necessary scientific standards. We report a prospective, single blinded, randomised control trial of 20 patients, which looked into effectiveness of the therapy. Subjectively, 45% of the treated patients were satisfied with the outcome and also had objectively increased their Constant score by 11% at 6 months. The control group experienced no subjective or objective improvement with p value < 0.03. This study confirms that extracorporeal shock wave therapy is effective in treating chronic calcific tendonitis when compared with a placebo group. However in our experience it is not as successful as previously claimed, with half the patients failing to achieve a satisfactory out come and requiring surgical excision. Patients found the procedure painful, which has not been previously alluded to.
体外冲击波疗法据称是治疗冈上肌腱慢性钙化性肌腱炎的一种有效的非侵入性疗法。然而，许多试验因未达到必要的科学标准而受到批评。我们报告了一项针对20名患者的前瞻性、单盲、随机对照试验，该试验研究了该疗法的有效性。主观上，45%接受治疗的患者对结果感到满意，并且在6个月时客观上其Constant评分提高了11%。对照组在主观和客观方面均无改善，p值<0.03。这项研究证实，与安慰剂组相比，体外冲击波疗法在治疗慢性钙化性肌腱炎方面是有效的。然而，根据我们的经验，它并不像之前声称的那么成功，有一半的患者未能获得满意的结果，需要手术切除。患者发现该 procedure很痛苦，这一点之前并未被提及。 （注：原文中“procedure”未翻译完整，可能是有遗漏，完整的应该是“治疗过程”之类，但按照要求不添加说明，保留原文状态）
