We analyzed relationships among tinnitus relief, dizziness, and results of vertical autocorrelation studies of head movement to investigate the effect of greater occipital nerve block on the sensory and motor system in 2 patients with abnormal head movement. Tinnitus improved in 14 (52%) of 28 tinnitus patients after occipital nerve block. The percentage of patients reporting tinnitus improvement (54%, or 7 patients) among 13 patients without a history of trauma was not significantly higher than among 12 patients with trauma (33% or 4 patients). However, tinnitus improvement in patients with dizziness but without trauma was more frequent than that reported by nontraumatic tinnitus patients without dizziness (p<.05). Vertical autocorrelation results while stepping in place were better in patients with tinnitus relief than in those not reporting tinnitus relief (p =.001). Dizziness improved in 8 of 13 patients (62%) with trauma, similar to improvement in 8 of 14 patients without trauma (57%). Improved word perception test results in the presence of noise suggested that improvement in tinnitus and dizziness after occipital nerve block was related to improved attention.
我们分析了耳鸣缓解、头晕以及头部运动垂直自相关研究结果之间的关系，以调查枕大神经阻滞对2例头部运动异常患者感觉和运动系统的影响。枕神经阻滞后，28例耳鸣患者中有14例（52%）耳鸣得到改善。在13例无创伤史的患者中，报告耳鸣改善的患者百分比（54%，即7例）并不显著高于12例有创伤史的患者（33%，即4例）。然而，有头晕但无创伤的患者耳鸣改善情况比无头晕的非创伤性耳鸣患者更频繁（p<0.05）。原地踏步时的垂直自相关结果显示，耳鸣缓解的患者比未报告耳鸣缓解的患者更好（p = 0.001）。13例有创伤的患者中有8例（62%）头晕得到改善，与14例无创伤的患者中有8例（57%）的改善情况相似。在有噪声情况下单词感知测试结果的改善表明，枕神经阻滞后耳鸣和头晕的改善与注意力提高有关。
