全参数生物反馈指标在主观性耳鸣患者中的应用

目的研究全参数生物反馈在治疗主观性耳鸣患者中的效果。方法对20例主观性耳鸣患者行全参数生物反馈治疗10次，观察治疗前后耳鸣残疾评估量表（Tinnitus Handicap Inventory，THI）得分及全参数生物反馈指标的变化。结果耳鸣患者治疗前后THI总分分别为44．9±22．3和28．0±14．8，差异达到极显著性水平（P〈0．01）；冶疗前后生物反馈指标肌电分别为6．7±1．6和5．1±1．2，差异达到显著性水平（P〈0．05）、治疗前后仪波分别为13．3±6．4和16．4±6．2，差异极显著（P〈0．01）、治疗前后SMR波分别为5．4±1．6和6．2±2．2，差异显著（P〈0．05）。结论主观性耳鸣患者进行生物反馈治疗有效，可明显降低THI总分，改善耳鸣症状，随着耳鸣患者症状减轻，其对应生物反馈指标也发生相应改变。

The Application of Biofeedback in Subjective Tinnitus Patients

Objective To study the effectiveness of whole parameter biofeedback in the treatment of patients with subjective tinnitus. Methods 20 patients with subjective tinnitus patients were treated with biofeedback therapy 10 times. The THI scores and biofeedback indexes were observed and compared before and after the treatment. Results The total THI scores of the tinnitus patients were 44.9 ± 22.3 and 28.0 ± 14.8 before and after the treatment, showing a significant difference. There were significant differences in electromyography （EMG） （6.7 ± 1.6 vs 5.1 ±1.2; P〈0.05）, α wave （13.3 ± 6.4 vs 16.4 ± 6.2; P〈0.01） and SMR wave （5.4 ± 1.6 vs 6.2 ± 2.2; P〈0.05） before and after the treatment. Conclusion Biofeedback therapy can significantly reduce the THI scores, improve the symptoms of tinnitus patients, reduce the EMG and increase the α wave and SMR wave, so it is effective in treating patients with subjective tinnitus.
