Opera singers train their vocal organ to have a good timbre of voice. They train and train again to have a strong resonance, large range of voice, homogenous color of voice, a voice goes far and to avoid vocal disorder, etc. This article is analyzing training> from scientific and medical perspective. It could approach the secret of the great art of 400 years history - . Furthermore standardizing voice training method based on training> will facilitate to train, therapy and care the voice professional user and voice disorders.

OBJECTIVE: To testify the effect of voice therapy methods for the glottal dysraphism patient with functional voice disorder. METHOD: The subject was a 62 year old man, who had been diagnosed as functional voice disorder of glottal dysraphism. The main therapy was voice training, with normalized noise energy (NNE) as the assessment and monitoring parameter of the voice function. The datum of the baseline period and the treatment period were collected, and were analyzed with A-B Single-Subject Design in statistics. RESULT: NNE had been significantly decreased (P < 0.01) through the systematical voice training. CONCLUSION Voice training had been the effective therapy for the glottal dysraphism patient with functional voice disorder.

OBJECTIVETo explore the effectiveness of voice training on professional voice users with voice disorders.

METHODSThirty one professional voice users suffering from voice symptoms without organic disorder were treated with a four-week voice training program, including vocal hygiene education, respiratory training and resonant therapy. Voice handicap index, maximum phonation time, noise to harmonic ratio, jitter and shimmer were compared before and after the training.

RESULTSThe voice handicap index (x(-) ± s) decreased from 33.7 ± 19.2 to 18.8 ± 18.4 after the training and the difference was significant (t = 6.14, P < 0.05). Maximum phonation time (x(-) ± s) increased significantly from (15.5 ± 5.8) s to (18.6 ± 6.0) s (t = -3.43, P < 0.05). jitter (M [P(25); P(75)]) decreased significantly after the training from 0.42% [0.36%; 0.62%] to 0.35% [0.29%; 0.47%] (Z = -2.51, P < 0.05), while there was no significant change in shimmer and noise to harmonic ratio.

CONCLUSIONVoice training can effectively reduce the vocal symptoms in professional voice users, decrease the handicap degree and increase the respiratory support during phonation, thus improve the voice quality.

OBJECTIVETo observe promoting action of Yintang (EX-HN 3) on expanding and unifying the vocal range of the singer.

METHODSYintang (EX-HN 3) was stimulated at the same time of singing, and changes of expanding and unifying of the vocal range of the subject were investigated.

RESULTSStimulation of the acupoint could promote expanding and unifying of the vocal range of the singer, and strength coordination and completeness of expanding of the vocal range and unifying of sound area for singing.

CONCLUSIONStimulation of Yintang (EX-HN 3) is beneficial to expanding and unifying of the vocal range in singing, and to increasing vocal function.

OBJECTIVES: To explore the character of laryngoscopy finding, voice, and therapy of vocal fold fibrous mass. METHODS: Clinical data, morphology, voice character, surgery and pathology of 15 cases with vocal fold fibrous mass were analyzed. RESULTS: The morbidity of vocal fold fibrous mass might be related to overuse of voice and laryngopharyngeal reflex. Laryngoscopy revealed shuttle line appearance, smoothness and decreased mucosal wave of vocal fold. These patients were invalid for voice training and might be improved by surgery, but recovery is slow. CONCLUSIONS The morbidity of vocal fold fibrous mass might be related to overuse of voice and laryngopharyngeal reflex. Conservative treatment is ineffective for this disease, and surgery might improve.

OBJECTIVES: To evaluate the therapeutic effect on the voice recovery of patients with vocal cord polyps undergoing the microsurgery of preoperative voice therapy. METHODS: Twenty-six patients diagnosed with unilateral vocal cord polyp under stroboscope, who needed to undergo vocal cord loss resection under supportive laryngoscope, were randomly divided into control group (non-voice training) and treatment group (voice training), with each group of 13 patients. Patients in control group were just treated with surgical operation. Apart from surgical treatment, patients in treatment group received 6 hours intensive vocal therapy one week before the surgery. The therapy courses consist of the propaganda and education of voice care, postoperative vocal instruction and the patients' self-training under the guidance of voice therapists. The acoustic parameters (irregularity, breathiness, grade, jitter and shimmer) of the same patient were collected 24 to 48 hours before the surgery and 14 days after the surgery with Ling WAVES. The results were analyzed with SPSS 19.0. RESULTS: The differences of all the five preoperative voice parameters between control group and treatment group are not significant; but postoperative breathiness and jitter in treatment group were significantly lower than that in control group, while the differences of irregularity, overall severity and shimmer were not significant between control group and treatment group. In control group, breathiness and jitter were significantly improved after surgery, while the differences of irregularity, breathiness and shimmer were not significant between preoperation and postoperation. In treatment group, all the five voice parameters were significantly improved after surgery. According to the laryngostroboscopic examination, the vocal fold polyps were excised completely in both groups. CONCLUSIONS Preoperative voice therapy contributes to the recovery of voice quality of the patients with vocal cord polyps. Combined intervention of surgery and voice therapy is an effective method to treat the patients with vocal cord polyps.

OBJECTIVETo investigate the role of airflow parameters of some specific examinations in voice function assessment.

METHODSThe s/z ratio, pulmonary function and phonatory aerodynamic parameters were measured in subjects with benign vocal fold lesions and with normal voice. The effect of treatment in subjects with benign vocal fold lesions was evaluated with the phonatory aerodynamic parameters.

RESULTSThe value of s/z ratio in the disease group was higher than that in the normal group (P<0.05). The value of PEF was significantly different between the disease group and the normal group for male (P<0.05). MFR, MPT, PTF, SGP, PTP, VE were significantly different between the disease group and the normal group (P<0.05). MFR, MPT, PTF, SGP, PTP of the disease group after surgery for both sex were significantly different from before surgery (P<0.05). The disease group was subdivided into two groups through stroboscopic examination before and one month after surgery: the worse group (with some functional laryngeal abnormality, or organic abnormality except benign vocal fold lesion) and the better group. PTF, PTP, SGP, VE were significantly different between the worse group and the normal voice group. There was almost no significant difference for aerodynamic parameters between the better group and the normal voice group (P>0.05). There was no significant difference between the worse group after 8 weeks'voice training and the normal voice group (P>0.05).

CONCLUSIONSs/z ratio, aerodynamic parameters (MFR, MPT, SGP, PTF, PTP, VE) are valuable for the diagnosis and assessment of the voice disorders. Aerodynamic parameters are sensitive to the change of glottal function during the treatment. Voice training can increase the glottal function of patients after laryngeal microsurgery.

OBJECTIVETo apply the theory of channels and collaterals to the study on teaching of singing and to resolve problems in teaching of singing.

METHODSAcupoint stimulation manipulation was used for channels and collaterals comprehensive systematic experiment for signing, and changes of voice quality before and after stimulation of acupoints were investigated.

RESULTSThe stimulation of acupoints is beneficial to discovering and developing a comprehensive controlling system potential for the singer, and after stimulation of acupoints the range of voice and the difference of the higher and lower voice in the subjects have significant changes.

CONCLUSIONStimulation of acupoints provides an experimental basis for teaching study of singing and open a new area of study for the theories of channels.
