Abstract:
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.
