The present study was performed on 20 patients randomly selected from a large group with noise-induced tinnitus in order to investigate the effect of acupuncture on their tinnitus. The patients were divided into two groups. One group first received classical Chinese needle acupuncture for 5 weeks, and the other was given a placebo procedure; after a 2-week interval, the procedures were reversed. A single-blind cross-over design was used. Acupuncture was given by a Chinese otolaryngologist around the ear as well as at distal points on the extremities. Placebo consisted of mock electrical stimulation via surface electrodes connected to a Chinese electro-acupuncture stimulator which delivered a weak sound and a light flash at a frequency of 2 Hz but no current to the surface electrodes. The effect was evaluated by the use of visual analogue scales. No significant difference between acupuncture and placebo was found in annoyance, awareness or loudness of the tinnitus. Many patients indicated a preference for acupuncture due to unspecific effects such as improved sleep, decreased muscle tension and improved blood circulation. It is concluded that acupuncture has no specific alleviating effect on noise-induced tinnitus.
本研究对从一大群噪声性耳鸣患者中随机选取的20例患者进行，以调查针灸对其耳鸣的影响。患者被分为两组。一组先接受传统中医针刺治疗5周，另一组接受安慰剂治疗；经过2周的间隔后，两组治疗方式互换。采用单盲交叉设计。由一位中国耳鼻喉科医生在耳部周围以及四肢远端穴位进行针刺。安慰剂为通过连接到中国电针刺激器的表面电极进行模拟电刺激，该刺激器以2赫兹的频率发出微弱的声音和闪光，但不向表面电极输送电流。通过视觉模拟量表评估效果。在耳鸣的烦恼程度、知晓度或响度方面，针刺与安慰剂之间未发现显著差异。许多患者表示由于改善睡眠、减轻肌肉紧张和改善血液循环等非特异性效果而更倾向于针刺治疗。结论是，针灸对噪声性耳鸣没有特定的缓解作用。
