摘　　要：目的探讨继发性功能减弱性发声障碍患者的嗓音训练治疗方法及效果,为临床相关疾病的治疗提供参考。方法以53例继发性功能减弱性发声障碍患者为研究对象,对其进行嗓音宣教、局部放松训练、呼吸及发声训练,并对嗓音训练前、后嗓音的平均基频(F0)、频率微扰(jitter)、振幅微扰(shimmer)及标准化噪声能量(NNE)进行分析,并比较其嗓音训练前后最长发声时间(maximum phonation time,MPT)、平均气流率(meaning flow rate,MFR)及发声效率的变化。结果嗓音训练后,患者F0提高,由矫治前144.5±15.021Hz升至194.59±25.42Hz;jitter、shimmer、NNE值,分别由矫治前的0.49%±0.09%、3.47%±0.89%、-6.35%±1.23dB降至0.17%±0.08%、0.95%±0.46%、-10.72%±5.51dB,差异有统计学意义(P<0.05);MFR由矫治前170.72±15.84ml/s降至122.54±21.75ml/s;MPT及发声效率提高,分别由矫治前9.14±4.08s,313.11±161.02ppm提高至17.16±2.427s,714.68±523.31ppm差异有统计学意义(P<0.05)。结论合理的局部放松训练、呼吸训练及发声训练可以改善继发性功能减弱性发声障碍患者的嗓音质量。Objective To investigate the effect of voice training on secondary dysfunctional dysphonia and provide reference for the treatment of related clinical diseases.Methods A total of 53 patients with secondary hypofunctional dysphonia were included and recieved conduct voice education,local relaxation training,breathing and vocal training towards them.Acoustic parameters(F0,Jitter,Shimmer and NNE)before and after voice training of the patients were analyzed.MPT,MFR and phonation efficiency were measured and compared before and after voice training with the help of speech sounding aerodynamics system.Results After voice training,F0 of the patients increased from 144.5±15.021 to 194.59±25.42.Jitter,Shimmer and NNE decreased from 0.49±0.09,3.47±0.89,-6.35±1.23 to 0.17±0.08,0.95±0.46,-10.72±5.51,respectively.MFR decreased from 170.72±15.84 to 122.54±21.75.MPT and vocal efficiency were improved from 9.14±4.08,313.11±161.02 to 17.16±2.427,14.68±523.31.The difference between before and after voice training was statistically significant(P<0.05).Conclusion With reasonable local relaxation training,breathing and voice training method,the voice quality of secondary hypofunctional dysphonia patients can be improved.Training methods in this study can provide reference for the treatment of related voice disorders.
