RESUMEN
Objective To explore the curative effectiveness of comprehensive voice training methods on teachers' voice disorders patients by using subjective and objective assessment. Methods Forty-seven teachers' voice disorders patients suffering from voice symptoms without organic disease and complete follow-up data as the research object were treated with a three-month comprehensive voice training program. Training content included relieving laryngeal muscle tension, improving the throat vocal cord movement and reconstruction methods of pronunciation. The use of voice acoustic analysis and voice handicap index(VHI) were compared before and after training. Results The jitter and shimmer were significantly decreased after comprehensive voice training from 1.06(0.79,1.38)％and 2.71(2.16,3.24)％to 0.78 (0.59, 0.99)％ and 1.64(1.03,2.45)％, the differences were significant (Z=3.249,-4.121, P<0.05). Maximum phonation time and dysphonia severity index were significantly increased obviously from (9.87 ± 2.61)s and-2.23±0.75 to (12.81±1.97)s and-0.43±1.65 respectively, the differences were significant (t=-6.057,-5.273, P<0.05). After the training, the VHI score of voice disorder index decreased from (37.41±4.96)points to (26.31± 4.29) points after the comprehensive voice training. In addition to emotional function, the difference was statistically significant(t=12.715, 5.881, 11.483, P<0.05). Conclusions Voice training can reduce the degree of voice disorders effectively, increase the power of the respiratory system, therefore improve the voice quality of teachers with voice disorders. The subjective and objective combination assessment can evaluate the quality of the patient′s voice more thoroughly and evaluate the clinical efficacy of voice training further.
RESUMEN
Objective To investigate the relationships of tone burst -ABR Thresholds and the pure -tone audiograms in normal hearing adults .Methods The response thresholds of Tone burst -ABR and the pure -tone audiogram were recorded from 34 adult(68 ears) at 0 .5 ,1 .0 ,2 .0 ,and 4 .0 kHz .The results were statistically ana-lyzed .The correlation of the response thresholds of tone burst -ABR and the pure-tone audiogram were studied . Results At 0 .5 ,1 .0 ,2 .0 ,4 .0 kHz ,the averages of the response thresholds of tone burst -ABR were 27 .43 ± 3 .29 ,25 .98 ± 2 .76 ,16 .78 ± 2 .37 ,and 12 .42 ± 2 .64 dB nHL ,respectively .The averages of the pure -tone audio-gram were 12 .23 ± 3 .99 ,11 .82 ± 2 .56 ,9 .58 ± 3 .23 ,and 9 .92 ± 2 .59 dB nHL ,respectively .The differences between the response thresholds of tone burst -ABR and the pure-tone audiogram were 12 .13 ± 4 .51 ,11 .43 ± 3 .66 ,7 .61 ± 2 .43 ,and 7 .17 ± 1 .32 dB ,respectively .At 0 .5 ,1 .0 ,2 .0 ,and 4 .0 kHz ,Pearson correlation coefficients were 0 .69 ,0 .79 ,0 .84 ,0 .89 ,respectively .Conclusion The tone burst -ABR and the pure -tone audiogram thresholds were a highly correlated with each other ,especially at 2 .0 kHz and 4 .0 kHz .Tone burst -ABR has the frequency specificity ,which can response the hearing level better .
RESUMEN
OBJECTIVE@#Comparative analysis of the clinical curative effect of manipulative reduction and TRV- CRP treatment of BPPV, comfort degree during reset and quality of life improvement.@*METHOD@#One hundred and thirty-two patients with BPPV were randomly divided into two groups ,one group underwent the traditional manip- ulative reduction, the other group with TRV-CRP. DRI and VAS was evaluated in the pre and after treatment and evaluation of the efficacy was conducted. The results of two groups were compared.@*RESULT@#The effective rate of manipulative reduction after a week treatment was 89. 23% and TRV-CRP.was 98. 51%, which was higher in TRV-CRP group than that of the manipulation reduction group(P0. 05), the score of the two groups were decreased after a week of reduction, but the improvement of TRV-CRP group was higher than that of manipulation reduction group(P<0. 05).@*CONCLUSION@#The success rate of TRV-CRP was higher than that of manipulative reduction,but manipulative reduction comfort degree was higher than TRV-CRP, the two methods can both improve the quality of life of patients with BPPV. TRV-CRP has many advantages over manipulative reduction, but manipulative reduction is simple with low cost, and the effect is still a great advantage. In clinical work, we should reasonable combine the two methods,so as to improve the cure rate of RPPV.
