OBJECTIVE
To evaluate the frequency of tinnitus onset (in normal subjects) and modulation (in tinnitus patients) during muscle contractions, estimating possible risk factors.
MATERIAL AND METHOD
This case-control study enrolled 121 tinnitus patients and 100 healthy volunteers who underwent medical history, ENT examination and 16 maneuvers of muscular contraction (head, neck and limbs). Modulation data were compared between patients with and without normal audiometry, well-defined diagnosis and symptoms of craniomandibular disorders.
RESULTS
The ability to modulate tinnitus (65.3%) was significantly higher than that to originate tinnitus (14.0%). The head and neck musculature was significantly more efficient than that of the limbs. Audiometric pattern, well-defined etiology and symptoms of craniomandibular disorders showed no relation to tinnitus modulation.
CONCLUSIONS
Somatic modulation is a characteristic aspect of tinnitus.
目的
评估肌肉收缩期间耳鸣发作（在正常受试者中）和调节（在耳鸣患者中）的频率，估计可能的风险因素。
材料与方法
本病例对照研究纳入了121例耳鸣患者和100名健康志愿者，他们接受了病史、耳鼻喉检查以及16种肌肉收缩动作（头部、颈部和四肢）。比较了听力正常与不正常、诊断明确以及有颞下颌关节紊乱症状的患者之间的调节数据。
结果
耳鸣调节能力（65.3%）显著高于耳鸣发作能力（14.0%）。头颈部肌肉组织比四肢肌肉组织的效率显著更高。听力模式、明确的病因以及颞下颌关节紊乱症状与耳鸣调节无关。
结论
躯体调节是耳鸣的一个特征方面。
